    My 32T is already on order. Supposedly shipping this week or next. Very excited as I like the climbing of the 30T, but want more speed. This should be spot on.
    I like 'em long, low, slack and playful

    hey guys. If you are interested about reading more in details why this ring is NOT biopace and what benefits are then I am taking active part in SS forum thread on this:

    http://forums.mtbr.com/singlespeed/o...l#post11468770

    Have a read if you are interested. Worth!


    Shipping- 16.9$ is actually a steal We ship from UK and 16.9$ for tracked parcel is actually less than Royal mail charge + envelope +stickers and fuel to the post. It costs me 19...

    My ring itself is 50% cheaper than Rotor one so this should not put you off. On top of that to use Rotor you need to buy 70$ spider.I charge for my chainrnig less than Rotor for a spider! So compare 200$ Rotor solution to my 66$ chainrnig. Suddenly postage is a wash

    just scroll down on our page and you will see a video showing that rear cage does not move at all. We sell a lot of these rings to singlespeeders as chain does not grow or shorten while pedaling. I know it's difficult to imagine it but it works that way.

    scroll down the page in the link and you will see.

    Re: Absolute Black Oval Chainring

    I have been considered a round 30T instead of the 32T I have for that extra low gear. Would the oval 32T actually do the same? Will it make climbing easier compared to the 30T? What about the highest gear, how will it affect top speed?

    Thanks for any input!

    oval 32t is easier than round 32T.

    oval 32T will be similar to ride something between 30/32T on round. Oval 32T will not be easier than round 30T if that's what you are asking.

    So that something between 30/32 would be a 31?

    From experience, I've found that it climbs as gear just a touch taller than a 30T round (as that's what I previously ran on my AM bike).

    I haven't tried a 32T round.

    I wrote it that way as It really depends on your personal perception. Some people will tell that it rides like 30T and some will write it's just a bit harder than 30T, but surely easier than 32T.
    On average, yes treat it like 31T to calculate gears for eg.

    First ride with oval today and it does feel between 32 and 30, and allows me to ride a gear lower.

    Absolute Black Oval Chainring

    Marcin,

    Wish I had seen this thread a couple of days ago! Just ordered a Rotor 30T QX1 and GXP spider from Bike24 in Germany. It hasn't shipped yet, so have tried to cancel my order with them. Put in an order with you and on the waiting list for the direct mount GXP 32. For those wondering, Marcin's solution is a whole lot cheaper than the Rotor setup. Should also be lighter than the stock setup since it's spider less.

    How is chain retention compared to the stock SRAM chainring? I have had very good luck with it since I bought the bike in April.

    Also, what position would the Rotor ring be in to compare to your ovality? Standing climbing or seated position?

    34T rings now available! But in limited qty for now, so don't think too long...


    34T is cheaper than 32T as it is flat with no integrated nuts into chainring. So it can be used on inside or outside position on 3X crank (inside is recommended).

    My ring is already known to outlast original XX1 by 3-4 times in durability and have same retention capabilities. We use better materials and more complex shape to achieve that.

    Our ring is similar in shape and position as Rotor "starting" position. Which in most cases is No 3 if I remember correctly.

    To be fair this is most optimal position for 99% of people out there. Only pro riders who spend countless hours on ovals can tell the difference if they rotate the oval by a bit. So no point of creating adjustability for something you will not benefit from at all. Even Rotor itself admits in their patent application, that only very few people will need adjustability. Most of you would only get confused. So we wanted to keep things simple and clear for everyone. This is the best position to ride with, so no point of fiddling with it

    Thanks for the reply. I was able to get my Bike24 order cancelled so I will anxiously await delivery of the 32 tooth spider less oval GXP. Website said it would be shipping in about a week?

    Will a 30t ever be produced for us that ride heavy fat bikes in snow? Also, how does these rings work for all mountain duties? That is, fast and punchy climbs up technical rock sections?

    Tehan... my question is not about singlespeed so I came here.
    Im looking for a 1x10 drivetrain using the 32t AB oval 104BCD chainring I already ordered.
    To get the correct chainline... should I use a 3x or a 2x crankset?

    Thank you.

    (42-11T e-13/xtr cassette).

    this ring is designed for hard riding so not sure what you ask. The slower you pedal the more benefit you feel from the oval.

    32T ring has integrated 2mm spacers which offsets ring by 2mm to the frame. So 2X crank is more than good. 3X crank is also good and it will move your ring by another 2mm to the frame.


    Just be careful as some new (2014) 3X cranks have 94bcd spider. They can be distinguished by 30T middle ring on them. If there is 32T it means normal 104bcd spider.

    Just pointing out that Merlincycles.com can ship to the US for free(over $80)

    Otherwise, I don't suppose ya'll wll create any rings for 86bcd?

    Love what you have done in the chainring space.

    Does this mean a 34 should feel abit more like a 33 when climbing.

    They could work I suppose. As they're narrow wide to stop the chain coming off, it'd be a bugger to shift between chain rings though.

    Re: Absolute Black Oval Chainring

    Hopefully will be doing a good long hilly ride tomorrow. Will be comparing the 32t oval and 11-36 cassette to the last ride on the same tracks with a 34t front and 13-40 cassette.

    You will get yours by Monday most likely as you ordered few days later.
    We always send according to order date to be fair with customer.

    Gearing felt good, virtually the same low gear with a higher top.
    Traction was good, and the best bit, after 10min, I didn't feel any "ovalness", it just felt natural.

    Similar heart rate to last time, but 4min faster.

    Got er done tonight, Absolute Black 34T Oval and a Wolftooth 42T GC on a Fuel EX 9.8 29er.

    302g/.67lb savings

    Rode around the driveway, worked good, felt the oval a little, won't be able to give it a real shake down for a few days. I'll report back.

    Absolute Black Oval Chainring

    Ordered mine on 11/7/14 and still waiting. They are not on top of keeping customer informed. I need a front chain ring lots of grinding noise it's a wolf tooth lasted three months. I don't want to buy another front ring if mine is coming soon?

    I'm pretty bummed out to I put my order in on 10/27/14 and the confirmation email from Absoluteblack stated delivery about 11/9 or a bit later??? I guess technically Absoluteblack covered his bases, but really??? I've sent 2 emails & no responses. Please give me a heads up, it's all I'm asking for!

    Hi Guys,
    sorry if some of you did not receive their rings yet. From a month or so we face huge increase in order volume and this impacts the response time.

    We are on top of shipping the 104 oval rings and everything else except Sram oval chainrings. These shipped to everyone who already ordered them before 5th October. Everyone else will receive them in about a week as we are going to send all backorders this week. I know this is a bit late but making spiderless oval chainring is not easy and we faced some challenges when we started making them at full speed. Hence a delay.

    But now is all sorted and you will get them very shortly.

    Why did you make the chainline on these 50mm, when the ideal should be 47.5mm?

    I was contemplating buying and XX1 crank, and one of these, but with the chainline 2.5mm more than ideal. i'd prefer to go with a 104 BCD one that I can tune with washers.

    Pity as an XX1 crank with this ring would have been an awesome setup and would have dropped a load of weight.

    Please also do not forget that new Boost 148 drivetrain system is going to be widely available in 2015 and this forces every single chainring manufacturer to change offset by 3mm outboard to clear the frame.
    Well except us, as we made a universal offset which is excellent in Boost148 and 1x10 current conversions and still very good in 1x11 conversions.

    So you buy 1 chainring from us and don't worry what system you have in the bike. It will fit for sure and can be changed between bikes if necessary.

    on 2X crank big ring is 52.5mm on 3X middle ring is 50mm (This is true for most crank manufacturers like Sram, Shimano, RF etc). XX1 crank has 49mm.
    Boost 148 will require 52mm.
    Our ring is 50mm

    50 will clear all chainstays. while 47-49 not really.

    What most people forget is that with 1X drivetrains you need to make a clever choice of front ring.
    Chainline is not that much important here.
    You should spend 85% of your riding time in middle of the cassette. If you don't do that currently that mens you have too small or too big chainring.

    Lets take an example.
    Someone has now 30T and says that he spends most of the time in last 3-4 granny cogs on the rear. This is not good and you wear drivetrain a lot. But if you change the front ring to something like 28T suddenly you have moved chainline "virtually" to middle of the cassette as you start using lower gears to have same speed.
    If you already ride 28T and you are in same boat - try 26T. If you ride already 26T and still using last 3-4 granny cogs all the time = time to move back to 2X as going smaller than 26T up front does not make sense.

    If you ride 32T and use 11-13-15-17 all the time- it is time to move to 34 or even 36T.

    In normal ride you should use your extreme gears only 15% of the time to have a perfectly healthy drivetrain. You need to optimize your drivetrain to your fittness level and terrain you ride. There is no shame to ride 28 or 26T up front if you need one.

    This is a best way to get as much from 1X as possible. Saying 47.5mm chainline is optimal is not true. It is not. This chainline is optimal only for granny gears. But if you change front ring according to your needs you will start using more of the middle of the cassette.
    Try and you will not regret.

    Tehan - I currently have a 1 x 9 setup (soon to be 1 x 10).

    I have a SS Q Ring mounted to the outside ring position on a 2x XT Chainset. This would give me a chainline of 48.8mm, as far as i have been able to ascertain. I have shimmed the chainring using 1.2mm washers to give me a chainline of 47.6mm. Ideally I should be using the middle position on a 3 x chainset to give me the same position.

    When I put the chain in the middle of the cassette, this looks close to having the chain running in a straight line (although I still feel the chainring could move in a little).

    Although I want to lose some weight, by switching to an XX1 Crankset and direct mount ring, having the correct chainline is more important to me as I believe drivetrain efficiency is more important than lower weight.

    I don't really understand why sram have gone with a 49mm chainline with XX1, and why the direct mount ones are even wider? Maybe I'm missing something, but for me a setup of 45 - 47.5mm looks to be correct. If you do a search on XX1 chainline issues, you'll find plenty of threads about people finding the chainline too wide.

    Another consideration is that when using an Aluminium largest sprocket, either with an XX cassette or a 40t range extender, I'd prefer to have the best chainline possible, so to keep wear to a minimum.

    I've never heard of boost 148 before, but I assume its a 148mm rear hub? Another standard that no one really wants? Why would I want a chainline compatible with this when I have no intention of buying a bike with it? (since i've only just begrudgingly converted to 142 since the bike I just bought has it, and have no intention of changing this bike for many years)

    I appreciate your analogy of using the correct size chainring to keep you in the middle of the cassette, however there is always going to be times when you have to use the biggest sprocket (often when you're tired), so you want the gears to be running smoothly in this setup.

    I'd have thought that if you manufactured a direct mount ring with a chainline that better suits 135 / 142 rear hubs, then people would be very interested in this!

    hey,
    What you describe is your personal case. We sell thousands of those and they fit perfectly well. We need to think globally not locally to supply the parts. There will always be the case where something may be less than ideal, but we can't cover all the bases. Same is happening with every single part from every manufacturer.
    99% of setups are really good with such a chainline.

    What you propose (47mm chainline) will have a negative impact on lower gears and make them hard to ride. So we will not do it.

    If you converting to 1x10 with XX1 crank then our spiderless ring will be on 5th gear - means ideal chainline.

    You can't have perfect chainline for granny gears and still have great chainline for small cogs at the same time. This is simply not possible with 1X. Some people complain on XX1 chainline as they use wrong ring up front and then use granny gears all the time.

    This is why I wrote longer post above. If you don't ride 85% of the time in sort of middle of the cassette in your local trails then you have a wrong ring up front.

    Boost 148 will be a standard for many many bikes in 2015 and 2016. Especially for 29ers. You will not change a bike in few years maybe, but another few million people will and we need to support them as well.

    Its not really just my personal case, since what I'm doing isn't unusual - i.e. run a 1x setup with a 135 / 142 hub.

    And I want the chainline of the chainring to line up with the center of the cassette, not for it to favour either high or low gears.

    Its my understanding that the chainline on mtb chainsets increased from what is ideal, in order to allow the front mech to function properly with oversize tubes. However this isn't an issue with 1 x setups (unless you're running large chainrings), so why does the chainline need to stay wider than it should be?

    Maybe a few million will convert to Boost 148, but ther'll will still be many millions more who will still be running 135 / 142.

    Do you have information on what the correct chainline is for a 135 / 142 hubs? Maybe I'm off wit the 47.5mm figure?

    I just wrote above that with 1x10 conversion and our chainring with XX1 crank, chainline is on 5th gear(that is middle of cassette). So not sure why you keep saying you need 47.5mm chainline...
    You just contradict yourself at the minute.
    What I am talking here is a standard setup with 135/142 spacing.

    With Boost 148 spacing of 148mm your chain would be on 6th gear in same setup as talking above.
    So our rings fit just fine. You just need to go an ride and stop worrying about those numbers

    Thing is no matter how you look or set it up a 1x will have a compromise either at the top end or low end.

    Thats the reason (fwiw) that the chainline be kept at center as much as possible.

    One can only limit the 'severed' chain angle by moving the chainring inboard or outboard with the effect of severely increasing the angle of the other end.

    Tehan has a point about staying in the middle if one is concerned about chainline. But still there is still a limit up to how many teeth a chainring can accomodate depending on the chainstay geo.

    Ie not all frames and/or legs can run 1x may it be oval or round. Theres always a limiting factor to everything.

    Tehan - you need to stop getting so defensive when I'm trying to have a genuine conversation about an issue.

    I ride plenty thanks - this is why I want my gears to run as smoothly and efficiently as possible, so that I don't cause premature wear to a very expensive cassette.

    I've asked you if you have any information on what the correct chainline is for a 135 / 142 hub, you claim that your chainline of 50mm is correct. This is contradictory to other information that I have been able to find which suggests that 45 or 47.5mm is correct:

    http://forums.mtbr.com/drivetrain-sh...ub-941112.html

    Here on sheldon brown, they say that 47.5 is ideal, this is where I got my figure from:
    Chainline on Bicycles with Derailers

    My issues is that with a 1x setup, there are no front mech issues requiring a wider (50mm) chainline, just chainring to stay clearance ( but a 34t oval works fine at 47.6 on my setup), so why not make the ideal setup, rather than one copied from multi chainrings?

    Well I can tell you for fact that the tall 42 tooth cog on the new 1x cogsets are creating massive havoc with the narrow/wide chainrings and wearing them out fast in the cross gear even at 49mm (Sram's standard). Going wider is just plain wrong I don't care what tehan is saying. And to suggest we stay in the middle cogs is also idiotic - anyone who lives in the REAL mountains knows that you spend MOST of your time in the largest and smallest cogs with very little time in the middle as you are either going UP or DOWN! FWIW Wolf Tooth just came out with a 49mm chainline for their RaceFace rings because they now uderstand this as DOES B-Labs with an even tighter 48.5mm chainline: B-Labs OVAL chainring
    The problem is real - I have a toasted 30t Sram ring after only 400 miles and there is plenty of info here on the Race Face rings going fast too with their 51mm chainline (the rear cogs are not wearing, just the narrow wide rings). The wider rear chainstays (for today's bigger tires) do play a part in this as the larger you go in ring size, the wider the chainline needs to be to clear the chain stays. 47.5 might be ideal but good luck clearing your chainstay with anything over 32 tooth on a modern frame. It's a balancing act peeps!

    Have FUN!

    Sorry if I may have come across as being defensive. English is not my first language so i try my best to describe what I think.

    Quote Originally Posted by xcbarny View Post

    And we got to the point. It would be probably ok on your own setup with your frame model, frame size, crank etc. But we sell to tens of thousands of customers with very different setup array. There are millions of combinations we need to fit into. But I understand it is easy to forget about it when you look only at your particular bike.

    There is no fixed figure for chainline number. On 10spd cassette 50mm chainline is perfect (and this is what you want) as it is in dead middle center. On 11spd it could be a bit improved, but soon most frames will require 52mm chainline due to growing chainstays and hubs and we are already prepared for it.

    Concluding. There isn't really something like ideal chainline on 1X. There is always a little compromise to be made. Like I wrote already 45-47mm chainline will not fit many frames with ring bigger than 30T(yours may be ok but we are talking overall) and most importantly such chainline would be only good for top 3/4 of the cassette.

    If you need such a chainline we offer 26/28/30T 64BCD rings for such extreme situations where you need only your granny gears. This will give you chainline of 45/47 dependent on 3X or 2X crank spider. But as you may notice we only offer sizes up to 30T as nothing bigger will fit with such a chainline to 90% of frames on the market.

    With 1X you have to make your own personal decisions. In your case staying with a spidered crank and mount our 64BCD ring may be a better option if you like smaller chainline then going spidrless. This is why we have many options to offer.

    In general on 1x10 conversion our sram spidrless ring is ideal.


    I will also write again. If you wear out your biggest cog very quickly then it means you use it far too often. That means you use too big front ring. If you would use granny gear like 40/42T only 10% of the riding time this cog would last a full season with no problem. This is why taking correct chainring up front is crucial.

    With our oval rings things have simplified a bit as Oval give you an "easier gear" comparing to same tooth count round equivalent. So you will effectively start using lower gears on the back and save your granny gears only for extreme situations.
    Please have a think about what I wrote.
    If you used 32T round then try 32T oval or 28/30T round and you will improve your chainline.

    uff. We sold lots of them and on average our ring last 3x longer than Sram one...

    What you say is perfect example where you have too big of a ring up front. 42T is a bail out gear not a half a day use gear. If you change your ring to 28T or even smaller one you will stop using 42T as often as you do now. Please have a think about it. This is what Sram is promoting all the time, but many people do not understand it.
    Please look what pros do with XX1. they change the front ring on every race according to terrain. why they do it? To stay in the middle of the cassette most of the time as you get less drag from chain= great speed at less effort.
    Of course in our regular riding this would be not convinient. This is why picking one correct size to fit most of your local stuff is crucial. Read what I wrote above how to figure out correct ring and you are good.

    We do offer smaller chainline as well on many rings. Oval 32T 104BCD has integrated 2mm spacers to push to 48mm chainline. But this does not fit 100% of frames.

    We do 64BCD rings in 26/28/30T for those extreme mountain situations where even with 28T up front you still use last 4 cogs all the time. Who said you need to use spiderless option in every single case??

    In majority of cases our spiderless option works excellent especially on 1x10 drivetrains. There is no argue with that.

    If you really need to use such a small chainline then consider buying a crank with a spider to fit our 64BCD rings. They are Very popular among our customers who live in mountains as they use mostly granny gears so this is perfect option.

    on the side note. You will not feel a difference between 49 and 50mm chainline under your legs or ears. I can bet about it. So making 1mm more does not change anything.

    Again. Choose your ring smartly to your needs.

    Absolute Black Oval Chainring

    I would agree that no one is going to notice 49 vs 50 mm. Not sure why everyone is beating up on Tehan since this chainline is the industry norm right now . The Next SL cranks I have been drooling over have a 51 offset. Wolftooth is 50. SRAM is 49 apparently. I get some grinding already with 49, but the short chainstays on my Mach 6 accentuate the issue.

    However, I don't pick a front chainring to "stay in the middle of the cassette." I pick the gearing that gives me the best RANGE for my trails. If I went to a 26 or 28 tooth, I would run out of gear going down.

    No, that's not the reason. The reason they have to do this is because of the limited range on a 1x drivetrain. You want low enough gear in the steep climbings, but also high enough gear in the descendings. Also, using big chainrings will be more efficient, so if you don't need a very low gear in a specific race, then you want a bigger chainring in front. A bigger chainring will also last longer than a smaller one.

    And by doing what you say you end up riding in middle of the cassette most of the time.

    Does any know of someone who does a direct mount oval ring to fit a SHORT spindle BB30 Crank please?

    Been on Google all afternoon, and all the manufactures I've found only do ones to fit GXP or BB30 long type only

    Many thanks if you can point me in the right direction!

    We will do it in late January. 32T oval for the start.

    There is no one on the market doing them at the moment.

    Tehan, please tell me you will be doing the DM S-Works rings before the Raceface rings as many of us have been waiting since spring for these.

    Wondering, can mouting the oval ring work if placed on the big ring position of a 3x crank? This might fix my chainstay clearance issue for my build...

    just installed my new A/B 32t oval and did my first ride.

    My setup: 29er hardtail.
    1x10 with SRAM X9 type2 rear D
    Raceface Turbine cranks
    Replaced Raceface 32t narrow/wide with Absolute Black 32t narrow/wide (104 BCD)
    Install was easier than falling out of bed

    The difference is a bit more subtle than I expected in terms of pedaling motion
    I kind of expected something more dramatic
    Nice though. Smooth. No dead spot. Power is just always on.
    No issues with chain line, or shifting quality. It's all just good.

    Very happy

    I didn't ask the question as a beat up, and the only reason it was directed at Tehan is because he's the only one from the industry who is actually talking to the the consumer here, so fair play to him for that.

    As you said, this is an industry standard thing, so I wanted to know, why when Sheldon Brown says the perfect chainline for an MTB is 47.5, has the industry gone with 49 - 51mm?

    Yeh, I get that its only a couple of mm, and most people won't notice, but it is something that I do notice. So if it means that I have to stick with a 104 BCD chainring, which I can adjust the chainline on, rather than a lighter direct mount setup, then so be it.

    Since it seems that the main issue is chainstay clearance, I'd say that there would be a case to have 2 different versions - one with the correct chainline, and one with the increased clearance chainline. Similar to how Sram have the 2 different q factor crank sets. Or just make the bigger ring sizes with increased chainline.

    I run a SRAM XX1 crank with a stock 30T.

    When I'm in the three largest cogs...I do notice a low rumbling noise from the chainring that I don't get in the smaller cogs.

    I remember seeing pics of Pro XC bikes, probably pre XX & XX1, where they'd put a spacer behind the cassette, and leave off one of the smaller sprockets, in order to get a better chainline on the bigger climbing sprockets.

    I actually tried putting different sized spacers behind my cassette. I bought a 1.2mm Shimano shim from Ebay...but it was too thick...I couldn't get more than 1 or 2 turns on the lock ring. There is a .9mm I'm thinking about. Right now I have one of the two shims that originally came with my OneUp 42T. I don't think its making a difference...haha.

    Did you take a smaller sprocket off to make room for the spacer?

    you should be able to move it over 4mm then

    No, I didn't remove anything. I'm still 10 speed. Only thing XX1 I have is the crank. My shifter is and X0 and RD is X9. I do have the Ridea 30T en route.

    This one is well worth reading about Oval rings (as we are quite similar to Rotor it also applies to ours):

    From Inside Peloton: SLO Motion ? Peloton


    "Round rings do not optimize the way humans produce power. Its as simple as that. Anyone interested in going faster on their bike needs to switch to oval rings. As OHaras study percolates through the pro peloton and the entire cycling community, 10 years from now, when only vintage bikes have round rings, we will look back on her study as the turning point."

    Will these fit Cannondale cranks? I have a 2015 Scalpel Team with the XX1 chainring. Can find any info on the cranks to see what BCD it is.

    If you have hollowgram cranks and want oval then best way is to get 104BCD spider for the crank and then our 104BCD oval ring:
    OVAL 104BCD chainring

    We do spiderless rings for Cdale but they are round.

    If it's an XX1 chainring, per SRAM's website, and Google, it's 76mm.

    You won't notice a chainline issue until the chainring starts to wear out. That said I think it's great that AB does have the option of narrowing up the chainline with their rings for the spider versions. My comments were for spiderless which is really what I want for a number of different reasons.

    Have FUN!

    Absolute Black Oval Chainring

    I hate to jump on the bandwagon, but I put my order in on 10/27/14 & I'm still waiting. Not very happy at the moment. The website said shipping around 11/7 & my current N/W chainring was just beginning to make grinding noise. I ordered up this oval chainring thinking I'd get this product in a reasonable time.

    At this point, instead of investing in another N/W chain ring I had to put on a spare crankset, spare normal chainring & an upper guide.

    Im holding off purchase until delivery issues are sorted. This seems to be a turn off imo...

    This is a good product and i hope logistics and the delivery do not mess it up.

    Ill be getting a green 32t shimano oval.

    Absolute Black Oval Chainring

    Moved the 32t over from the Stumpy hard tail 1x10 race bike to the new (to me) Kona Unit.

    Going from 26" to 29" will effectively gear things up, but the Unit's 180mm cranks will help there...


    It feels like the benefits of extra traction are more pronounced on the single speed than the gearies.

    Won't be long before I'm a repeat customer though...

    Precisely what I found. On a singlespeed gearing down and shifting the weight way back for a slippery uphill is simply not possible. The oval ring made loss of traction more gradual (because the effective gearing is higher at the point where crank torque is highest) and allowed to quickly get over the dead spots to start another stroke.

    Guys, At the moment we are getting a large amount of orders still. We try to catch up but because Christmas is just behind the corner do not expect USPS to deliver it on time.

    Many customers say that parcel was held by US customs for more than 2 weeks alone. This is busiest period of the year. It has always been for postal agencies. So you really need to be a little bit more patient.

    All old orders we sent long time ago so most of you should have it by now. Contact me if you have troubles on email and I will help you to find where it is.

    In 99% of cases you were not home and parcel is sitting at your local post office for those who don't have it yet. We found that very common. Usually postman "forgot" to leave notice.


    My good advise - order and wait for shipping note. We ship backorders first and list is long at the minute. So we don't expect to have free stock any time soon. Just place the order and you will get it in first/second week of January most likely in US.

    Most of the issues are not with us not delivering, but with USPS being very slow. Many internet shops already write "delivery time 14 days". It is this time of the year..

    Hi Tehan !

    I'm fond of absolute black's oval NW chainring, but with the new BCD standards (96bcd for my shimano xt :/), do you plan on releasing them ? I'd buy one the day it comes out !!

    Thanks

    And standing and climbing on the SS, you get better at adjusting body position for better traction at different parts of the pedal stroke compared to sitting and spinning.

    hey,
    No plans for 96BCD. This is only on some oem 29er bikes. It's 10x better to sell this crank and get normal 104bcd version of XT.

    If someone require smaller oval than 32T we are going to make 28T oval for 64BCD. This will be great for climbing on 29ers or enduro bikes if someone can't push 32T at the moment.
    28T oval will be 26/30T equivalent in round in min/max radious. This should fit on your crank as well as it is as far as I remember 64/96BCD.

    For those who wonder how the chain tension looks like on SS bike here is a small example.



    As you can see it is correctly tensioned on the biggest radius and slightly slack on min radius. This is absolutely fine. Chain will never drop and you get less chain wear as it is not stretched to maximum all the time.

    Mine came today also. 32 tooth SRAM GXP Oval Direct Mount. I am going to sell it, as I bought a 30 tooth from B Labs while waiting for this one (since Nov. 2). New in package, never used, never mounted.

    PM me if you are interested. Same price, $82.90 shipped via Paypal. The advantage from me is you won't have to wait long for it. SOLD

    Had a chance to test it out, first off adjusting to the oval ring was very natural and easy. In your head you think it will feel so strange, but its feels like the old 32 tooth ring it replaced when spinning.

    Now the good part, I love it!! I found myself getting out of the saddle more and just powering up hills in a lower gear, but now it just felt smoother with less energy wasted. In the saddle I felt it less but I was still going faster in lower gearing. It was like this "something just felt better", can't wait to keep testing it out. Great job on the design of ring, it could be a bit tighter on crank. The Sram spider is tighter with less slop, but when the screws installed all nice and tight. Saved 30grams of weight!!

    Question...
    In my 1x10 is better to use a 10s chain (got shimano m981) or a 11s (maybe dura-ace 9000)?

    Ty.

    Our is different to Blabs so I would keep it on your place. We have slightly different clocking which minimizes feeling of the ovality.

    thanks for feedback.
    Sram has quite wide tolerances on the crank splines. So it vary from crank to crank. Therefore we keep it with minimal play. Some will find it a bit loose and some will find it almost perfectly matching the crank splines. Those 3 bolts hold the ring actually(not the spline pattern as a whole), so this should not be a concern.

    I like how well it matches your bike!

    both chains will be absolutely fine.
    The only difference would be in deep mud. You would get less rub from 11spd chain (on 10spd cassette) as it is slightly narrower in outside diameter, so leaves bigger gaps between rear cogs.
    Other than that you would notice no difference.

    Tehan, are you definitely planning to make a short spindle pf30 sram direct mount oval? Reason I ask is my yelli screamy has limited chainring clearance, so that with Sram gxp cranks I'm currently running a Wolftooth short spindle version ( it has no offset, so chain line on a gxp crank ends up about 55mm). 99% sure I could run a 32t oval version of a flat, no offset sram direct mount...

    Or if you feel really ambitious a direct mount for lightning/s-works cranks would be awesome on my Stumpy, currently running a Wolftooth on that as well, would love to try an oval.

    What's the largest 1x chainring you've fitted a yelli screamy?

    I'm planning on using a 32t shimano oval but it might screw the chainline...

    ^^^I'm just running a 30t right now Spyghost. Check around in the Canfield forum there's a thread where people talk about different chainrings and cranks on the yelli. All I know is with sram xo cranks I could not use a standard Wolftooth direct mount 32t. With a the non-dished pf30 short spindle version it would work, I just ended up getting a 30t. Chainline is out there at 55mm but no problems yet, probably some increased wear in the long term.

    I have a couple of rides now on the oval ring and liking it a lot. Despite my best efforts to change, I am a lower cadence guy. My first ride I didn't feel much difference, but didn't feel awkward either. Second ride out I noticed that my legs felt fresher throughout the ride. I do feel a bit more improvement at lower cadence than at faster cadences. Not a Strava guy, would be interested in whether people get a measurable time decrease.

    The DM Lightening/ S-Works rings were supposed to be done last summer. Not even sure if they plan on doing them anymore. Several riders in my area including myself have been waiting for these, hopefully it still happens.

    my honest answer would be - sell this crank while you still can and buy something like X0 or similar so you can use spiderless version or some crank with 104BCD spider.

    120 in 1X is surely a dead BCD.

    Have been testing the oval 34 for a month now, setup as follows

    XT rear der
    XT cassette
    One Up 42 cog
    One Up 16 cog (poor shifting)
    34 Oval chainring

    Previously had the 34 and 30t Race Face, dropped a chain in both of them (once or twice) and haven't dropped a chain on the Oval yet, very pleased on the quality of the Absolute Black

    So if I have a BB30 short-spindle crank, the GXP ring will fit but result in ~45mm chainline?

    correct. This would not be a problem normally but many frames these days will not allow for such chainline and you will have some rub on chainstay if you use GXP ring on short spindle BB30 axle. Some frames will accept that but general rule is that they don't. Hence there is a need for a flat version of same ring.

    Yesterday was easy test. I can tell you that the oval definitely works
    - It is easier to pedal uphill slope
    - The legs are less burdened
    - The chain does not fall out even at maximum load
    - Perfect changing all 10 speed (SRAM cassette 11-36)
    For now I am more than satisfied. I'm waiting for the weekend and a longer ride as well as larger and long uphill climb
    More about the experiences in the next appearance ...
    P.S. next week I will have the opportunity to test the smaller A / B oval 32T ring

    This. I'd like to get some, but don't want to have to find and use a 104mm BCD spider. I just sold mine.

    I think I may have destroyed a chain in a race yesterday. Checking it after the race and it has gone from less than .5% to more than 1%. There's about 5cm of slack. Not one chain drop. Including a 20min rocky descent.

    we are out of stock at the minute but will have more in 4 days. Shipping time to US is about 7 days at the current speed of USPS.

    I really do recommend to backorder and wait (max 5-7days). We always send older orders first. So if you order today and another 200 people will order tomorrow, then once we get stock your order will be sent first...

    I just ordered the required parts to convert my Mojo HD from a 1x9 to a 1x10. I have E13 DH/AM cranks and was going to replace my 32t round ring with a RaceFace narrow wide 30t to go with the new XT11-36 cassette.

    I'm looking to improve my climbing ability. I know a 30t round ring and a 11-36 cassette will give me more power but would I be better off with a 32t oval ring for climbing? From what I'm gathering a 30t round ring is more power but the oval ring is a slight increase in power and puts in me in a better cadence making climbing easier?

    I won't be riding for months yet so if a 32t is recommended over a 30t round ring I would be able to try it and I have plenty of time for it to arrive.

    Neither will help you produce more power. I'm not sure why you've come to that conclusion.

    An oval chainring may simply make producing that power feel smoother. There is no evidence that they will help you produce more power.

    Well I know my body won't physically be producing more power but I'm talking about a drivetrain with a ratio that will make climbing easier. A 30t round ring with a 11-36 cassette is going to have more underdrive vs a 32t round ring with the same cassette. So I guess I'm looking for opinions which setup would be best for improved climbing. More underdrive with a 30t x 11-36 or the more efficient power delivery of a 32t oval ring and 11-36 cassette?

    Moment many of you have been waiting for. RaceFace Cinch Oval rings are here!
    32T oval for the start with 30 and 34T coming in few more weeks.

    Visit our web for more details:
    RaceFace Oval

    Lighter than original round ones, with great oval shape and possibility to adjust the clocking position of the ring if you want to. This is the Ultimate solution for your RF crank.



    Long description:
    Our main/recommended clocking position is a fantastic setup for everyone (same as our other rings in the line). However some more experienced riders may like a bit more aggressive clocking. RaceFace oval chainring allows you to change clocking position by 22deg both ways from initial setup.
    RF Cinch mounting pattern is the only one out of all direct mount chainring patterns on the market (like Sram/Hope/E13) that can be rotated by every 22.5deg (16 spline design). That coincides with 2 positions that oval users love.

    Our main (signature) position is located around 3.30 oclock. That means crank arm is located at 3.30 oclock when major axis of the oval is at 12 oclock (vertical). That gives greatest benefits and excellent feel of the ring.

    Our second position in RF oval rings is located at 4.30 oclock. That is 22deg later than our main position. You need to turn the ring clockwise by one notch on the spline pattern. This position is favored by some experienced riders out there who already rode oval rings for few years from various manufacturers. We do not recommend it for people who just started the experience with ovals as this position is more pronounced and aggressive. We encourage customers to play with second position only when they have ridden on the main position for minimum 5-6 months (or ridden other ovals for longer period of time).

    Chainring has a mark on the back side of where the main position is. That mark needs to be located in the middle of crank arm.

    Our oval 32T ring is only 62g vs 68g from RF. But oval 32T rides like 34T equivalent (RF 34T is 70g). That makes RF Next SL crank with our 32T oval ring lightest possible setup on the market (for that crank).

    I placed my order for the 36t soon after I saw the above email, and while it only took a few days for the package to be shipped from Poland, it's now apparently been stuck in some NY sorting facility for more than a week.

    Anyone in the US have had a similar experience? Can it be stuck at customs?

    Here's the USPS link in case anyone is familiar with what it actually says.

    that is normal when USPS is busy. It just sits in their facility and it is not stuck in customs so not to worry. By monday it will move to your destination. We have seen it thousands of times now in last 2-3 months.
    It just means that they have more parcels than they can handle at the moment.

    Tehan, you are great, thanks so much for keeping us updated. Like many, I can't wait to order a couple of Cannondale direct mount ovalized rings from you.

    Absolute Black Oval Chainring-oval.jpgjust got my sram spiderless oval ring. it left poland 4-9-15 and arrived here in the west coast (CA) today 4-17-15. it had some scanning activity at the NY ISC, Bethpage NY distribution center, Industry distribution center, and at the norwalk Post office. however the carrier did not scan it. i talked to the carrier before and said that they don't really scan foreign parcel it is like a hit or miss if the scan the foreign parcel. but it is here
    i ordered it 3-13-15 and it was supposed to ship 3-28-15. not bad for ten days of delay

    just have to figure out the correct orientation to install it.
    i am guessing with the cranks in horizontal position, install the chainring where the x-axis is the longest?

    any pointers on how to install it correctly?

    Hi
    SRAM it only mounts one way. The three torx bolts are tight with loc- tight so be careful not to round them out. And use loc-tight when reinstall or they might come lose. Your chain line might be off the new ring is 2 mm less off set then the one you have take off. You might need to shim the cranks all the way over so the chain will stay on the rear cassette when you freewheeling in the 42t or your lowest gear.

    Good luck. You can lay both chainring on a flat surface and see the difference in backspacing. AB has the back spacing for a single speed. This my only complaint about this product I would pay an extra $20.00 for the right backspacing.
