    Pro Bike Supply among others... Apparently they are making a ton of them to send to suppliers soon...heard thru the grapevine

    Not sure about the 34t, but I am sure if there is a demand for it, they will make it..

    Give them a call..

    Ah, great. Thanks for the heads-up.

    I wonder if QBP or BTI are stocking any. Any idea?

    Does the price seem really high? Are they made in the USA?

    Todd at Black Cat was selling these RCR direct-mount chainrings about a year or so ago. Not sure if they are still available or not...



    Disclaimer: I've never used one of these ring so I can't vouch for them. They look nice though.

    I have an order in for a B Cat as we speak, so that would be convenient. Thanks for the info.

    Renthal also makes rings, although no spiderless.

    Well, I know folks have used Boone and Blackspire in the past with good success though I have never really seen places to order either of them. You can also look into Rotor Q as they also have an SS ring though it is an elliptical shape.

    If you have a M960 crank you are very limited however due to the odd 102 bcd but I believe Blackspire makes one that fits. (unfortunately, this is what I have so the HBC is the best option at the moment as far as an SS ring goes-not because of customer service)

    Surly also makes SS rings and I suspect you can get rings from Truvative as well (I mean they put them on the Stylo cranks right)

    Anyone know what the chainring (non-spiderless) size needed for the SRAM S1400 crankset? I know it's a 4 bolt. I'd like to look into the Salsa rings as a possible holdover for an HBC if I don't go with an MRP, especially since the Salsa comes in red.

    Yep, I would have been all over the Salsa's myself but the M960 while a great cranks, has a stupid frickn bcd size! While it might be available in black or silver, it is only available in red in the 104 bcd.

    There's a big thread in the drivetrain forum about the bling rings. Apparently there's some issue with the first batch being out of round. I figure that would be a problem with SSers

    I know it would be for me (SSr) as you end up with tight/loose spots. They say it is minute but you can still see it when you rotate the pedals, at least that has been my experience anyway. I actually have a little bit of that going on right now with my HBC ring and Surly combo. I thought maybe it was the new Surly cog that I have so I slapped my White Industries set up back on and still have the issue.

    One thing you can do is mark how you mount it when you first put it on. If you have a tight spot, you can try to take it off and rotate it to see if that helps even things out. I have heard that it can also be the actual bolt locations on the crank as well. None the less, I have been doing fine with it but I certainly would not want to buy one knowing that this is an issue.

    That's why they were selling them at a discount and there was a disclaimer on the MRP site stating the rings were out of round and that they could possibly be an issue for SS'ers but not so much for geared bikes.

    I heard about the MRP problems from a friend yesterday. He's running an MRP and just ordered a new RCR ring today.

    By the way, if your ring has bolts, you can try to set the cranks at the tight spot, then loosen all of the chainring bolts, allowing the chainring to scoot over ever-so-slightly, then tighten the bolts again. Most rings have low enough tolerances at the bolt mounts that you can get .5 mm or more by doing this.

    Hi guys,

    Pro Bike Supply does not have the rings in-stock, be warned. There has been at this point (6/6/2012) only one production run, and that production had the imperfection mentioned (ie probably not suitable for single-speed use).

    We are currently producing more and adding 34t and 36t as well. I don't have an ETA. They are being machined right now.

    We have no plans to make the Bling Ring in any other colors.

    Cheers

    Oops...I stand corrected.. apologies. Seems like you will be missing out on a ton of biz by not offering of "bling" colors...

    Why not ano them for us??

    Go ahead and check in to the Homebrewed Components thread and see what we are having to deal with. Help!!

    Thanks! I just got mine today and it's the same. I saw a couple sites selling them saying that they were 104 and most of the others said 120, so I wasn't sure. Kinda sux that they are 120 though, nothing out there for that size.

    They're perfectly round, no problems there. And yes, they are sitting on a small batch of both 32T and 34T, black like mine and also silver.

    He hasn't done 30T yet but I bet he'd be open to it.

    This is RCR Fabrications, a metal fab outfit in Santa Cruz. Just google the shop # and call Josh. They do all of Todd's (Black Cat) drop-outs, etc. Todd asked them to do a small run of chainrings last year. They have just a handful left and I believe he's selling the remainder for $40-50 each. When he does the next production run, there will be a price adjustment.

    The whole RCR crew is top-shelf. Really friendly and competent folks.

    Did you mount that ring yet? We're discovering a bit of eccentricity to the SRAM splined interface (so even if the ring is "round" it'll look "off" once mounted and spun).

    Mine is mounted to the cranks as you can see, but it's not on my bike yet. A friend of mine ordered a ring at the same time and mounted it to his new FORM SS and it's perfectly round, works flawlessly. I wonder if the SRAM eccentricity is consistent from one set of cranks to the next, or if one set will have the "wobble" to it and the next won't. Do you know? First I've heard of it.

    Salsa 94 mm 30t set up single speed with a 19t rear and new 8 speed chain. Died in less than 10 2-hour non-epic rides. Salsa's warranty response,"Single speed 29ers are hard on chainrings." Replaced with a Surly stainless steel.

    I won't run the Salsa rings again, even if they come in pretty colors.

    Sorry to turbo-post in this thread...

    I've had the same experience with Salsa rings. I went through 2-3 of them before I figured out that it was them and not me (I really wanted to believe that the teeth were splaying out because of the sheer power I produce).

    I would get about 3 months out of a Salsa ring before the teeth would get so smashed/splayed that they would catch inside the chain links as the chain rolled through.

    They are junk. Salsa knows it and doesn't fix it. Says a lot about Salsa.

    I am so happy to see that there are quite a few alternatives out there at this point. It sucks that there aren't much of any for the 102 bcd M960 but I suspect at some point, I will just end up getting another crank. Then again, i still haven't flipped my HBC over yet so I suspect I have some time!

    Sounds like cutting edge business practices at this point doesn't it...hahaha. Perhaps you can even expect them to deliver it and not cancel your order w/o even asking AND after waiting 2 months and receiving zero emails

    Post up and let us know your thoughts on the chainring please.

    IMO, we really need to educate any company capable of producing top notch chainrings that they stand to make some $$$ by taking out HBC.

    I know that sounds mean, but that guy has had plenty of time to rectify the BS he pulls and just doesn't seem to care enough to change anything. Oh well...biz is biz..

    Peace

    Oh..and thanks V-kid. Much appreciated

    I'm curious, MRP is also making Sram spiderless rings along with HBC and RCR. This eccentricity would seem to be evident on all spiderless rings, right? Or, what has MRP done to resolve the eccentricity you are finding with these cranks that the other offerings aren't doing?

    I think a little competition in this market segment will do well for HBC--relieving some of the pressure (both Dan's and his customers'!).

    Update with initial impressions about the RCR rings made for Black Cat-

    These aren't spaced at all. This pushed my cog closer to the dropout about 2-4mm. I believe i calculated this out to a 55mm chainline from center of my BB. Might be an issue for ppl running tensioners or freewheels.

    They fit nice on the Sram spline. A better fit than even the spider that i removed. I spun the cranks to look for a wobble at the teeth and the black center ring. No wobble at all. These appear perfectly round on my cranks.

    These have pretty skinny teeth. I'm not sure how long they will last being aluminum. I am also concerned with the tooth spacing. Top & bottom (12 and 6 o'clock) you can tell the teeth are engaging the chain and i get a tight chainline. At 3 o'clock, the chain is noticeably loose. This means it is only engaged to the chain on the top and bottom of the chainring teeth and not around the entire front teeth (say 1-5 o'clock). I can also notice noise when i spin the crank. I think this is from the teeth grabbing the chain only on the top and bottom and not evenly around the entire front side of the ring.

    I have not ridden these yet, but, my initial impression is that these rings aren't going to last long with this much "play". If RCR thinks about making a new run, they will need to fix this issue. Although, i did compare the teeth and spacing to a new Truvativ 32t SS ring and they appeared to be nearly identical. Maybe just wider teeth would fix slop with more engagement area.

    Just thought i should share so the community can make an informed decision before ordering.

    Much appreciated jetboy. Keep us posted. I won't have mine on a bike for another couple months. My buddy rode his 200 miles this past week and no complaints yet.

    That would resolve the super soft issues they have with the aluminum cogalicious version. Hard do drop a large bill on a cog that may be swapped for different sizes depending on the trail.

    They look nice! I do agree though, at about $100 for a cog I think I would still go with a King and call it a day. My Surly has been holding up well and I haven't received my HBC alu version yet to compare things.

    Looking forward to hearing about your HBC cog in May 2013.. Lets hope he sends you the correct item ordered

    I know right! Well, the Surly is holding up well but its a 17t. My plan was to have a 16-19 set up but so far I haven't bought any new ones. I'll probably get another Surly for the 16 and 19 but will probably end up replacing the 17 with a King and probably the same for the HBC (if it doesn't come in by the end of next month). The King is pretty light and is stainless and costs about $55 but best of all are readily available! I just don't want to go have my buddies shop order me the King only to have the HBC show up the next day. Then again, I could probably sell the HBC and make a profit since I would actually ship it!

    Living in the mountains and running a 34x21 makes finding nifty cogs difficult. Anyone know why Chris King doesn't make anything larger than a 20T?

    Maybe the weight? Maybe wear on a 21t on aluminum is enough to not need the stainless? Maybe because 32x20 is near identical to 34x21?

    With a combination of chainring and cog you should be able to replicate the gain ratio in multiple possibilities. Now, gain ratios having the same chain length for a magic gear is another story.

    A few posts back in this thread, I talked about how I was blowing out Salsa rings in just a few months. I noticed the next day that my current ring, which I've been riding for a year now, is actually a Salsa. I didn't think it was. The difference is that it's a 34T, whereas I always rode a 32T before.

    So that's the primary reason I stick with the 34x21 vs the 32x20 I always ran. Drivetrain wear is dramatically reduced.

    Most people here in Prescott ride a 32x20 and a 34x21 is just a tiny bit taller.

    Maybe you mentioned it, but why not drop the front chainring down to less than 32? More wear? How so? Just wondering...please inform

    The forces exerted on a drivetrain are spread out over a larger area when chainrings and cogs are larger.

    Gotcha. I do see that most BMX streetstyle guys seem to run tiny front and rear chain ring and cog mixes though... Hmm..

    A guy I know said they do this because there are essentially less teeth to break and less chain links to break and it is lighter...

    Which is better?

    Well, having been into the bmx scene for a while I can tell you that it also provides more clearance when doing grinds and what not.

    None the less, you will experience more and faster drive train wear with a "micro drive" set up than a more conventional 32:18 set up. It is however lighter and looks pretty cool. But a bmx chainwheel is only about $30! Chains are only about $20! And Drivers for their free hubs are pretty cheap as well unless you go with the Profile ti version. The mtb scene seems to charge alot more for these same parts and we are riding considerably further distances than the average bmx'r.

    In comparison, a top of the line rear der for a mtb (lets say an XTR) is about $200-240! A new Campy Super Record EPS 11 spd rear der is about $900! Just ridiculous! (I want one though!)

    Do BMX drive trains see the forces that our bikes do though? I mean BMX seems like short bursts of power that only last a very short time whereas our bikes see more sustained strain because of the length and steepness of some of the climbs we do. I could be completely off base though...I've never ridden BMX so someone correct me if I'm way off.

    I think bmx runs more steel rings compared to our aluminum rings. That will increase the lifespan of the smaller drivetrain. We wouldn't worry so much about wear if we had more Ti options.

    Perhaps more significant is the chain carries less tension when chainrings and cogs are larger.

    They fit nice on the Sram spline. A better fit than even the spider that i removed. I spun the cranks to look for a wobble at the teeth and the black center ring. No wobble at all. These appear perfectly round on my cranks.

    Thank you so much for taking the time to write all this down! It's invaluable information to note when we are thinking about the next production run. After sending a few of these out the only complaints have come from people riding 8 speed chains. People are pretty stoked otherwise! As I have said before, these were developed for the handmade show in Austin a couple of years ago and we are just now really thinking about doing another run. We just want everybody to be satisfied with their purchase and get their product FAST. We would also like any suggestions for budget minded riders on choice setups for spiderless rings! I can't even afford to run these on my own bike! They are 7075 Aluminum so they should last quite a while. With regards to tooth thickness, we found that .082" seemed to work the best with the geometry. I believe I copied this from another ring that I had laying around the shop. The width was probably snagged from the same ring. I plan on keeping everybody posted as I get better at this forum stuff. You have to be on it to avoid getting torched! Thanks for the help!

    I think we all welcome additional options if you will Please get on it and make some good bling for us. Trust me, if the product is top notch and the customer service is there, it will be a WIN WIN.

    Word spreads fast around here if you haven't noticed already..

    Thx!

    RCR,

    I think the "play" i noticed may originate from the tooth profile. They seem to be very vertical and the loop below each tooth where the chain roller sits is a bit wider than the roller. Since this thread is about HBC alternatives... i will use Dan's ring to compare tooth profile.





    Notice how HBC is slightly more ramped and narrower in the valley between the teeth. RCR ring is very round. 12 and 6 o'clock teeth on the RCR ring does hold the chain very well on the sides of the teeth. Its just the slight play on the valley portion around 3 o'clock that shows that these teeth are providing no support during pedaling.

    As for performance, i haven't noticed an issue yet. I do fear extra wear due to the tension on less teeth over a short period of time. The ring may hold up due to harder aluminum, but, it will wear on the chain more with all torque going into about 6 chain links instead of 12 or more.

    If this one issue was adjusted and you make more tooth counts, so far, i will be back for more. I also actually like the jelly bean cutouts. Thank you for the current support.

    ... and if we just ... RCR rings

    Basically, you guys rule! I am stoked for the input. Sheesh. I just want to go ride! Good news is, this all seems easily remedied. I do know somebody that has been riding his ring for over a year now and it keeps on truckin'. But, there is always room for innovation and refinement. I am going to have to bust a few out of some 6061 and check all these geometry suggestions before I go big on some 7075. Now, to Nicene Marks and that big ol' hill!

    ok, seems it was misunderstanding. I don't have them yet, so am not selling anything.

    This is what i designed recently.
    32T - 51g (alu 7075 T6)
    Tooth shape almost identical to E13 and i have tested this shape already on my other prototype.


    When i actually make them i will pay advertising costs for sure. Right now i am only showing what i have designed. Hope this helps. Otherwise i would have to create new thread every time i want to show what i have designed.

    If there was any money to be made off of these I could pump out a couple dozen a day. Im working up a one off chain ring and a couple different rear cogs for my bike, then "breaking the mold". Unless these are getting made over seas, your either going to be starving or they are going to be too expensive.

    it's not that bad if you have a friendly machine shop with some spare time in the crisis era. I have done few different cogs for myself and they are at reasonable cost. But agree that setting up cost is not low.

    to be fair i don't live from that - it's my passion so i can afford small markup. But i hear what you are saying. "made in China" is everywhere now... and it's our choice what we want to pay for.

    Well, it seems there's enough market that HBC is so behind that there's a 4-6+ month lead time. Not sure how many he's making per day, but if he pumped out 12 a day at $45-100 a pop and is that far in the weeds, there must be hell of a market and some money to be made.

    The passion is why we do this, but this is such a niche market. I wish you the best, and would absolutely love to see some finished products. There are so many different variables, with tooth count, bolt patterns, and mounting style. Everyone is almost a one off, (Hooray for CNC). I spent alot of time going to school to be a machinist, although its not my trade any more.

    For the right set up and the right shop yes there is, I dont think youd get rich, but I wouldnt see that someone starving to death doing it either. I dont know why hes so far behind (work load, time management, ethics, or otherwise). I couldnt pull it off. The family machine shop thats been around for 50+ years is billing out a couple hundred dollars an hour on current projects. If we were making these we'd be starving.

    If you made 12 a day at 252 business days a year(3000ish total), sold them at 45-100 each your looking at your looking at between 130k-300k(costs are not figured in). Good luck selling 3,000 of them. Realisticly cut your sales to a couple hundred tops, calculate your time, materials, shipping, etc. Dont forget uncle sams cut! If it pays for your new bike this year your ahead of the game.

    Im not trying to start a war here, but trust me I wanted to do this. Passion doesnt pay my bills.

    I have received quite a few inquiries for custom rings and the like. As RCR is a general fabrication and machine shop, we tend to work better with the design already done. Take the thinking and trial and error out of the equation. Provide your own CAD drawings where geometry can be grabbed for CNC easily. You will save a lot. Design time is still at the same shop rate so it can add up when just general guidelines are given. I do think there is a market for our rings but it is very difficult to compete with Taiwan and China once they get there s--t together. So far, we have a big hole we have to dig out of before we even think about making any money on these things of bling.

    RCR,

    Honestly, your design is already working. But, would be better with 2 fixes... A slightly wider mounting area to bring the ring inward a slight bit (only needed for those who want to run a chainguide really) and fix the tooth profiles. The teeth on my e.13 has a good fit on the chain. Just wish they were a millimeter taller. Other than that, its good. That said, if i knew CAD i would get this to you asap.

    Btw, i just did a 30 mile ride with your ring. Mostly great, but, 2 times i got a slight "thump" that i felt with my pedals. I have only got this since adding the ring. I think its the feeling when the chain settles. I can't confirm, but, still believe the tooth profiles are the cause of this.

    Technology is awesome isn't it? Without it, those two suggestions would have taken days, weeks or months to get to me. Both are things that I am incorporating into the next incarnation of these rings. CAD work has already begun! I am selling these off, at a loss, and am stoked on the valuable information that I am gathering. This run was made with the input of just a couple of people testing. Now I have a couple dozen. Thank you so much for your purchase and the help!

    Colors...colors would help sell as well. I mean when you get right down to it, a reasonably price high quality product should be enough, but offering a little bling won't hurt either.

    RCR, to better show what i'm talking about with the tooth profile i have taken pictures to point out the "play". I know you got something in the works, just wanted to put an image to the text

    it's not a tooth profile. I had same problem with my very early designs as well.

    It's the spacing of the tooth - seems calculation was wrong for circumference. You will get it wrong by 0.02mm on tooth spacing and after 15 tooths you get 0.3mm error.

    Jetboy23,
    Nice shots! Tehan is right. Totally looks like a circumference issue. Is that an 8, 9 or 10 speed chain?

    Nubster,
    All the kids are asking for the candy colors! Sounds like a good idea to me!

    Velokid,
    Those dropouts are all Todd, and all Black Cat. I wish I was as cool as Todd. He just provided the .dxf file and we crap em' out on the the ol' waterjet. Bike parts from email? Awesome.

    Chain is a KMC z610hx. No ramps for gears. It was a perfect fit on my e.13 guidering. Maybe i'll pull out a 9sp chain and try the fit sometime.

    this has probably been beat to death in the SS forum, but I couldn't find it. Can someone school me on the pros/cons spidered vs. spiderless. I am building a new ride and all I have ever used is spidered, and wondering about spiderless. thanks.

    No chain ring bolts, slightly less weight and IMO better looking.

    I'm going spiderless to reduce a bit of weight (main reason), possible tooth counts under 32, and a cleaner look. I lose the bling options of colors (unless you go with HBC) since MRP and RCR are currently 1-2 color options. And, only HBC is doing Ti (my ultimate dream).

    Haha. Good one.

    Again, are you Dan? No, I didn't threaten Dan. Perhaps he felt threatened by me when I told him I would like to speak with him in person a year ago.

    Today, there would be a huge line of folks wanting to have a word face to face with Dan. You doubt this??

    It was not a threat, but I guess it could have perceived as one.

    I don't doubt that Dan is a good guy. It did bother me how he responded to me and my concerns way back when...struck me as a bit arrogant, as others have picked up on too..

    So move on from talking trash about his company every chance you get. You don't even ride his stuff. You never bought anything from him either as he canceled your order. That's my point. I get others complaining that paid for stuff and don't have it or are still waiting. I would be pissed too. Again, you simply come off as a woman scorned.

    I would think those Velo's are the same as all the other 7075 4 bolt 104bcd rings. In my opinion, these rings are very similar in performance and longevity. Just find one thats a color you want and go either weight weenie or not. HBC makes beautiful rings for this application. At least from the pics i've seen of them (no, my account wasn't hacked just because i said something nice about HBC). With this application, its a pick your flavor type of thing.

    We really need to see the offerings that are in the more custom area of the less common bolt patterns or spiderless for mountain biking. Also, still waiting for a spiderless SRAM titanium option. 30t Sram spiderless Ti ring is my dream.

    Thanks, it measures round. This one is new and not from the original (flawed) batch not recommended for ss use. I'll slap it on soon and report back after some abuse

    Because the quote on your post is referring to the fact that the Bling Rings are made to only work with SRAM cranks.

    I went through a fair bit of agony getting my chainline set to use a freewheel and an HBC chainwheel. Looks like the MRP wouldn't work on my setup since it's dished. How much chainline offset results from the dishing?

    Hows that RCR ring holding up?

    Besides the RCR and Bling Ring's what is available for the Sram spiderless interface? HBC isn't on the radar anymore I'm afraid. Is Boone making one?

    I took the RCR ring off due to some slop around the teeth. It was running fine as far as i know. I hadn't dropped a chain from the slop. In the 150mi i ran it, it seemed to wear fine, too. I just didn't want to be 15-20mi from my car and have an issue. It seemed like the load was being placed solely on 5-8 teeth compared to the full chain contact area.

    Since MRP came out, i've been running that and have been very pleased. I wish they made odd tooth rings as well. Would have loved Ti. But, my 30t seems to be wearing well and shows little to no signs of wear after about 600-800mi.

    I'm a little late to this thread but check out North Shore Billet for some great new SRAM spiderless chainrings. Just ordered up a 31t today. I suspect I'll see this one just a bit sooner than the HBC 104 BCD that i ordered 9 months ago and no longer have a use for.

    Titanium alternative:

    I haven't seen it mentioned here yet, but there is another option for titanium spiderless chainrings:

    .:: Carbon-Ti - Hi Tech Bicycle Components ::.

    They are available 32t through 36t for Cannondale, Specialized, & SRAM/Truvativ.

    I just received one, ordered through their US distributor, Apollo Components.

    I have not used it yet, but it looks nice, although not as blingy as the HBC I am running now. Will try to get a picture up.

    Here are some pictures of the Carbon-Ti spiderless ring. Looks really nice, and only weighs 62 grams.

    Cost was $160 delivered, a touch more than an HBC Ti ring cost when available.

    Rennen is pretty alright in my book. I have not been able to ride it yet due to weather but I have owned to HBC chainrings in the past which one bent in half and the other I sold. Compared to HBC I think they're about the same expect I think Dan did a better ano job.

    What's up with the weird decorative lines that serve no purpose other than to increase cost?

    All these grooves for decoration and minimal weight decrease would seem to only be a great crevice for dirt and grim to accumulate. Cleaner is better imo. Those Absolute Blacks look real nice, though. Just could do without the squiggles.

    That a milled ring. You can make all the machining in a mill. those grooves are the machine marks aftewr milling the dish with a small ballshaped/halfsphere tool. a 3 axis machine that is.

    Otherwise you need to oput it in a lathe to get the dish. 2 machines, instead of 1. Also a lathe with live (spinning) tools can be used and then you can make it all in one single machine too.

    Or it could be cosmetic. I don't care for that look at all. Looks suboptimal to me.

    MRP Bling Ring is about $65 (average US dollars) and the 54Euro converts to $70. More expensive.

    Will be racing remainder of season on MRP Bling Ring 1X10 set up. Sram crankset.

    EDIT: Well, nope ;(

    After taking my crankset apart and installing the nice Bling Ring, I reinstalled the crankset.

    Hmm... Why is the ring nearly touching my chainstay and why is it WAY off from my newly purchased E13 guide?

    Answer: Bling Rings can not be used on PF30 BBs. The spindle is too short! Well...crap in a hand basket!!!

    To MRP's credit, on their site, it does mention that they are to be used with GXP type only...but it was like finding a needle in a haystack on their site.....argh.

    Gave me an excuse to spend another G on my bike..haha. Just went with the XX1.

    Frame is NINER RDO fwiw...

    I think you forgot that it is German shop (Europe). So if you buy from US you don't pay vat. So it works out to 45 eur that means 59$ with current exchange rate. Shipping is not expensive either. So it works out cheaper.

    I do like the red, but loss the extra marks please. Form should follow function.

    seems i missed that 35eur shipping. But anyway it works cheaper excluding shipping. So paying 60$ in US from US shop would be ok i guess.

    These markings are because of technology used. This gives ideally round chainrings as it's done from one clamp. Not like putting material on lathe and then mill (mrp does that - thus early problems with roundness). Here all is done on the mill and these grooves are really tiny and shallow. So function is on first place. It works Making it really smooth would increase cost actually.Homebrewed Components Alternative-closeup.jpg

    If only i could get a Sram splined Ti ring.

    tehan, if the AB rings got a US distributor, i would probably try them out. For now, MRP is working great and wear has been really good.

    haha. Don't know if you have tried ti chainrings, but my experience with Ti cassettes and chain was poor. I expected longer life due to material properties, but it turned out that it dies as quickly as steel ones. So am not sure anymore if there is a big sense to that apart of the bling of Ti.

    I have also on one of my bikes a 40T titanium (Carbon-Ti) ring and wear rate is very comparable to the aluminum one it replaced. The only difference it that Ti one cost me 3x more
    Of course there are methods to reduce wear on titanium but they cost a fortune, so already expensive ring gets just even more expensive.

    Personally I like the look of the absolute black chainrings. Squiggly lines included.
    I see hills.

    I want to climb them.

    Best part is the weight:

    MRP: 28t -53g, 30t -58g, 32t -72g, 34t -85g, & 36t -94g

    Absolute Black: 28t -44g, 30t -48g, 32t -51g, 34t -67g, (36 in the works)

    NSB: 28t -75g, 30t -85g, 32t-95g, 34t -105g, 36t -120g


    This is 30% lighter than MRP and almost 45% than NSB. Finite element testing and "funny lines" can pay of very nicely. At the end of the day who does not want to have a bit lighter bike here and there, which is reliable as heavier bike and cost you exactly the same?

    Now I'm interested, funny lines included! Since these are a result of the milling process and not added for decoration, I don't mind and I like red. How are the tooth profiles and how do they preform?

    Tooth profiles are very similar to the ones from e13 single chainrings. Proven and reliable. I have tested tooth profiles on other rings in my singlespeed 29er (33x18) for over two years and am still able to use same ring with new chain! (pictures will follow on monday)
    Tried these also with no bash/chain keeper (but with type 2 rear mech) and chain retention is really good. For the stuff i ride (wet roots, rough, often muddy terrain) is perfect. But for rockgardens i guess a bashring and chainkeeper would be a good idea - if you tend to hit a lot with a chainring.
    Anyway, if you hit something often a bottom bashguard is wise to have. There is no such chainring which can take brutal abuse from rocks and keep straight all the time. It's because it does not matter how wide is the base of the ring - tooths are only 1.9mm in all chainrings and they simply can't take big hits and remain straight.


    forgot. About those funny lines. Extralight products are made in same way so you can see their crank here:
    QRC 2

    Same with All Hope brakes (levers, bodies and calipers)

    I am working on it right now.
    First production should be in US within 5 weeks. Will keep you posted.


    Few photos from todays ride.
    Yes it's UK and we have snow from yesterday... with mud. This is a custom brown color in case anyone wonders. This setup is with XX casette (12-36) and X0 rear mech and 32T on the front. I know i have a front mech still on... but chain retention is very good like it is on the photo, so i have not put any chainguide yet - as maybe i will not have to buy one. There is absolutely no problem with chain line in such setup. What i found is in most cases one rides in mid section of casette anyway for 60% of time, so chain is almost straight then.

    Okay. Not sure if it makes a difference to anyone, but here's why I was confused, according to their website:

    "We are based in Woburn, UK so please mind on local time."

    In any case, they can't do a shimano version at this time...

    Already posted this on another thread. Drop-stop teeth (XX1 style) allow use without a chainkeeper, im running a standard X0 short cage and 10spd chain with no problems so far.

    Apologies for the crap photos, camera setting were wrong.

    We are based in UK What you have seen in the link is our Dealer web shop in Germany. I am in process of updating our own web site with the product, but our German dealer is quicker then me

    What spines are you interested in for Shimano? I mean do you speak about spiderless version or 104BCD XX1 style rings?

    Hi bkirby, I'll have these available by the end of the week, if you would like to test one out and provide feedback shoot us an email. The old 95x series are our favorite too, I plan on putting the 952's on my singlespeed build this summer, let us know, Thanks - Colin

    I will do them, but it will take some time. Design is not a problem now - it's all about setup of CNC to do it in right money. This takes a lot of time to set up a line and make tools to hold the chainring while machining. It's not a printer or a garage tinkering.

    Understandable. Let us know if/when you get it done. There has got to be a few older guys besides me who love the older Shimano cranks (V1 or square taper BBs)...

    all is on the site. All sizes and colours will be in stock in first week of May. We are now milling as we speak.
    You can preorder and this will get you ahead of the queue as dealers have preordered quite a lot as well, so we have to meet the demand.

    Watch out Bikerumor as well as i have sent them red for test, so they should get it next week.

    i can put my hand on that. You have to understand how they are made.

    MRP uses lathe first to make a dish. Then they put it on the mill to get the tooth shape and rest of holes. This is risky and you have to be very careful to not to get it out of center when mounting to mill.

    Mine are done from one Clamp on the same cnc mill table. That means crank interface and tooths are made from one clamp and there is no way to make it out of true. It is just not possible that way to make it bad. This allows me as well to drop the cost of milling by a bit, so i can offer them to you at lower cost than MRP or NSB -simple. Not everyone can do that as it requires very fancy and expensive tools to do it that way.

    You could probably write a program that first measures/probes and then makes an automatic datum shift (or just rezero) for each piece, and the only "cost" would be the time it takes for the probing and shifting in that tool. Its not that hard to get stuff centered though. i did some 200 round pieces once that were for ultra high speed spindles, everything needed to be perfectly balanced when done, clamped them in the mill with one of those chucks that have 3 points (like in a lathe). And while you think this would center the pieces right?? They were off by about 0,2 mm all off them and that was unacceptable for those pieces. Had to do a datum shift/new zero for each piece. 0.2mm out of center is not that much for a chainring imo. to get that accuracy you only need operators that are not monkeys or retarded. Nothing special is needed.

    Depending on how much material is removed and condition of the material, how the material is removed and internal tensions and stress that gets relieved and crap like that, hardening before or after machining etc, stuff can get out of round/warped after all machining is done, it happens. and the more material you remove and the more aggressive you remove in the least amount of steps the more likely it is to happen. To avoid this precision stuff is always machined to leave room for this until the last step which only removes like 0.1 or 0.2 mm, usually by grinding instead of machining. Not one single part on a bike is a high precision/tight tolerance component though (imo)

    Is anybody making Sram spiderless 39-40T chainrings? I'm looking for a chainring to put on the Sram S950 crankset on my CX bike.

    Hi, this is all fine when you want to make one at a time - then i fully agree. But if you are making 20 at one go on the table... it's not possible (or rather waste of time to make it cost effective)

    all is on the website. Chainline is 50.5mm. That means that the chainring will sit exactly where your middle one is on the triple set crank. So it is identical to MRP in that matter. This is the best spot for the chainring as it works well with upper and lower gears of the cassette.
    So simple answer- chainring is dished, not flat.

    You can avoid chain keeper with mine as well. New production Tooths are slightly different to the photos i showed sometime ago now. I was holding it back to the last minute to wait for test results from pro riders - and they came excellent.

    What we found out is that we can avoid having wide/narrow tooths and retain chain same way as XX1 - all the magic is in the tooth shape itself . In May you will be able to find out yourself. Good news is that i can still keep 60$ retail and you don't need chain keeper.
    you can pre-order now as well on the web.

    exciting times!!

    I am taking your word for this - just ordered one of your 32t rings in black (scott in Canada) most excited about the weight loss over the MRP 32t direct mount!

    Do you feel it will be reliable enough for XC racing with no chain-guide and a clutch rear derail on a hardtail?

    Hmm... Why is the ring nearly touching my chainstay and why is it WAY off from my newly purchased E13 guide?

    Answer: Bling Rings can not be used on PF30 BBs. The spindle is too short! Well...crap in a hand basket!!!

    To MRP's credit, on their site, it does mention that they are to be used with GXP type only...but it was like finding a needle in a haystack on their site.....argh.

    Gave me an excuse to spend another G on my bike..haha. Just went with the XX1.

    Frame is NINER RDO fwiw...

    Yeah, the Bling ring and BB30 or PF30 is tough. Mine works on my BB30 Quiring ONLY because it's a 28t ring, and clearance at the chainstay is barely enough. If I ever go to a bigger ring up front it won't be a MRP Bling Ring.

    before 15th May (so in about 4 weeks). Sorry can't rush it more than i already done. Everyone need to sleep from time to time and having 16h day, every day, is not something one can do in long run.

    Do you feel it will be reliable enough for XC racing with no chain-guide and a clutch rear derail on a hardtail?
    Hi Scott, thanks for a business!
    I don't see any problem with XC riding and chain retention. Only really aggresive enduro riders or some serious downhillers should use chainkeeper as there is no miracles. When you ride really big stuff, chain does what it wants, so even best ring will not handle it on its own. But regular stuff what people mostly do is no problem.

    Hi jetboy,
    You can preorder now if you want on the web. Shipping is in middle of May as stated on the site.
    To make it clear - chainrings you see on my site currently ARE the new design. So what you order now is that new design. I will not make old one anymore as there is no point in that.
    Will change photos as soon as i get them from photo studio to not confusing more.

    If it hasn't already been covered, North Shore Billet makes nice spiderless chainrings and has them in stock ready to ship.

    Tehan, how are the rings coming along? I'm interested but don't want to pre-order after getting scammed by homebrewed components.

    Funny you posted that. I just pre-ordered 2hrs ago. lol. Can't wait to try them out. I will pay attention to the 45 day cuttoff, though.

    They are milled already. Now i need to get them to anodizing plant which should take no more than 12 days according to shedule (1-3rd is national holiday where i make them) so can't get it done quicker.

    If i can't keep the date stated on my site - you will get your money back at the same minute you tell me to do so. I am here not to get just few bucks come on guys... The main difference between me and Hb is that i don't do all the stuff by myself- that would be suicide. So i hire professionals to make the chainrings for me. I am best at design and they are at milling the stuff. So i have time to answer your emails and deal with distributors.
    Jetboy - your blue ring will be made along with everyone else. don't worry. I have found distributor in US finally, so soon it will be easier for you guys to get them there. How soon? - don't know yet.

    If you are talking about RL 104BCD crank then this will not fit (only bontrager i remember is the carbon one made by truvativ - this would work)

    But don't worry. I am launching soon XX1 style chainrings for 104BCD. These should be done by end May - more news soon on those.

    XX1 STYLE - Shimano

    tehan, i wasn't suggesting that there will be an issue. I'm very excited to get one of these rings. I'm shocked that you're on top of orders enough to know it was a blue one that i ordered. Thats awesome.

    I am waiting patiently, just not for more than 44 days. lol.

    warhawk spiderless chainrings

    I just added our hurricane spiderless chainring to our growing collection of spiderless chainring designs. I'm keeping several ring sizes in-stock and utilize JIT (Just-in-Time) manufacturing meaning that even if we don't have a chainring in-stock it only takes a few hours from the time the order is received to machine and ship the part. Our rings have been tested extensively and we are now machining these rings with our new taller tooth profile which will be the same tooth profile used on our soon to be released XX1 compatible chainrings. If you have any questions let us know, Thanks - Colin

    Sure no problem, I just weighed these here at the shop:

    Warhawk Industries Hurricane
    Spiderless Chainring
    Weights:

    28T(68g), 30T(74g), 32T(87g), 34T(112g), 36T(124g)

    The hurricane design is not the heaviest or the lightest among other rings but remember take into consideration the weight to strength ratio. Our rings are ~40% stronger then the lightest competitors ring. If you case a log crossing or need to pivot over a log you don't have to worry about bending one of our rings. If you have any other questions just let me know and I'll get some of the other weights up for our other designs soon, Thanks - Colin

    Great info! I was expecting them to be heavier, but they look like a great strength to weight alternative.

    Just wondering if anyone has any more plans for Shimano spiderless rings? Haven't heard anything in a while and was just wondering...

    jetboy - it was kind of luck that i know it's you but figured that out.

    Warhawk - thanks for weights. I missed them on my site for comparison chart.

    Since mine are the lightest out there i am just curious how did you come up with that 40% stronger value. I am specifically interested in your back calculation... will you share with us?

    Besides, Tank is stronger than a family car by "500%"(i picked that number as it looks good). But people ain't drive tanks on the street as most of them figured out that car is safe enough to drive...
    That's why FEA is so brilliant as you can take weight off of the part without scarifying the strength. I am not the only one who discovered that feature you know
    Secondly - if you pick a lot stronger material, then you can make a lighter part. Since i use the strongest aluminum currently available to public, i can also shave a lot more weight. I have missed on your site what material you use, so don't want to comment more on that.

    To make story short. Heavier does not necessary mean it is stronger. These things does not go in common when using different materials and FEA (i know it sound wired for some but that is true). Sometimes heavier means weaker - for those who used FEA i don't have to write more. For others - heavier means more rigid in most cases, and rigidity is not a good thing in some applications and some axis (don't think about chainrings but about all the engineered parts). It's a very large topic...

    It's not arguing. I just noticed in general that people sometimes make statements without any backup in calculations. So wanted to shed more light on the topic which is very interesting on its own. FEA is a blessing of modern times. Just look back 30years ago and look how heavy many things were. This was because lack of performance materials and lack of calculations. Imagine yourself calculation on paper of 500,000 points in FEA analysis... no go. (well some airspace and car companies did that with 100s of mathematicians, but it's an exception)

    ok enough moaning.

    We have a few out on the trails being tested right now and plan on having these available within a few days. I'll post a reply when they are ready to order, Thanks - Colin

    As long as a chainring can handle my less than incredible strength, i'm good. If i drop my ring on a log, or rock, or anything really... then i fully expect it to take damage like any other chainring not built for bmx freestyle or trials riding. Maybe some will handle the abuse, maybe some won't. I expect them all to fail if i abuse them though. So, i don't.
