    Smile 29 x 35mm carbon fiber DERBY RIMS Grand Opening

    Hi Friends,

    Thank you all for providing so much technical trail bike knowledge. I've learned so much and met so many great people over my 15 years participating in the MTBR forums.

    Now it's my turn to give back and serve the trail bike community, with what I know many including me have long been asking for.

    I'm introducing here the first WIDE carbon-fiber rims for mountain bikes, 29 x35mm and 650b x 40mm.

    See Home for details, and a limited sale price for the first 10 rim sets.

    I want you to ride them first.

    I could go on and on what a game changer these rims make in optimizing 2.1 and larger tire performance for stability, grip, and handling, with DH/FR durability and XC weight.

    BTW, I've posted an MTBR classified ad. And updated my signature as per the forum policies.

    on the 29er rim, how wide is the ID? where are they manufactured? Who designed them? is there a phone number we can call you to dicsuss?

    Really interested. How are these mounted to 100mm hubs? I ask because I've been changing bike configs a lot, and I'm starting to wish for something I'm not sure exists, which would be 135mm wide front suspension. I don't need much suspension. I have a Jones with a fat front that I like a lot, but sometimes I need just a little more than pneumatic suspension, but I like the precision of the wider stringer front wheel...

    These rims look like a sweet option. Now if I can only find a way to taco one of my crests without hurting myself, so I need a "replacement".

    Awesome product idea. Insufficient warranty. For example, Specialized (big, bad, I know) offers lifetime to the original owner, and crash replacement prices when you need them. No need to purchase ahead of time.

    Sticking with the Rovals for now, but REALLY attracted to the size of these!
    Whining is not a strategy.

    It costs you $200 for each LB rim , landed in the USA. You are telling me you would not pay an extra $100 for an additional year warranty and a crash replacement program that would cost you 50 percent and you could be back on the trail in one week?.. Ha ha....

    Where you getting the "$200" from? Its $50 to ship two LB rims. These Derby rims are $379 also.

    Two LB rims shipped= $350
    Two Derby rims=$758
    Difference=$408

    Very cool you've decided to follow your passion and provide a neat product, but come on man, who's ridden these and tested them and such data you can provide, because these aren't super cheap??

    Small suggestion for your web site..change the colour of the font so it is darker and easier to read for us older folkes. Also, seriously, you don't need WIDE in orange everywhere on the page, makes it seem like some BS scam page that try's pushing crap with buzz words.
    One day your life will flash before your eyes, will it be worth watching??

    LB - $165 x 2 = $330
    Shipping $ 50
    Paypal $19
    TOTAL $399.....$400

    DERBY is running a Special at $279 x 2 = $558 + Shipping..call it less than $600.

    What is the difference ??

    Oh, BTW. 3mm lip vs. 2mm lip means that the part that needs to be the strongest is going to be less prone to fail.

    Have you calculated how much it will cost you to replace your LB rims ??

    Wow. I feel so good hearing so many positive vibrations!

    Other than my day job, and a short 2 hour ride before dark last night, since announcing the Grand Opening till now I've been non-stop replying to emails from derbyrims.com and filling orders.

    The first day was great!

    3mm thick "hookless" rim walls, which is 0.5mm more than the thickest hooked rim walls, adding minimal weight but much durability from rock hits when flatting, and a wide surface to prevent most tire or tube snake-bit pinch flats. Although, I managed to pinch flat my tire landing a drop on a sharp rock with very low tubeless air pressure, making minimal damage to the rim with no rim repair needed. See the web site for a picture of this damage.

    The factory is confidential, but it's not in the US, I could not afford this risk otherwise. ENVE rims are the only make in the US, and this is the main reason each rim's MSRP is $900, and rumor is they will be producing rims in China soon as some of their other components are.

    mxer, Thank you so much for the order! You won't be disappointed. Yes, 29mm inner width, and coming in at 445 grams on average now, some a little lighter, a couple were up to 450 grams. XC light in weight, DH/FR durable.

    My P35 is 1mm wider inner width. I was riding those, and then tried carbon rims and the weight drop was very noticeable, but the major loss in handling and stability with the same tires was very disappointing. So I started last October researching the feasibility of getting carbon fiber real wide rims made.

    It turned out I had to invest in the molds to get it to happen, and design the rims. It's been very interesting, but I need to work a regular high tech high stress job to pay the bills. So working on this wide rim project mornings, evening, and weekends, it's been and still is a very long process in communication, design, critiquing, researching for any patent infringements (nope!), re-designing or adjusting design, communicating my design with the carbon fiber expert factory engineers and couple of carbon fiber manufacturing experienced friends, over many cycles, waiting for money transfers of my hard earned savings to get there trusting I wasn't going to be ripped off, then weeks waiting for the steel molds to be CNC'd and pictures of the first rims for testing, expert failure force testing, waiting for evaluation rims to build myself and ride (such an awesome experience riding my own design! and an instant handling confidence gain riding them, the performance improvement is incomparable, and that I was on the right track to proceed in risk), more design, communication, mold changes, setting up the business banking, business and sales licenses, bookkeeping myself, getting the web domain and building my own website and adding a shopping cart and designing and now managing that, proceeding with blind faith and much prayer that my very hard earned life savings was not just in vain, not just for my own ego inflation and riding pleasure. I almost quit 2 months ago, totally stressed out affecting my energy for my real job, to consider if I could be just to be satisfied I was riding these great rims and having learned much about rims and business. I stopped the project for a few weeks, then proceeded with recharged energy to bring these great rims to you guys at a price we career hard working recreational riders can afford. The first day of sales has been very encouraging!

    At this point, unfortunately, shipping from the US to outside the borders is extremely expensive for "oversized" packages with the major shipping companies, like $350 or more per rim set package. Maybe foreign individual buyers can find a way to order a pick up shipment at a reasonable cost with one of their counties shippers. I hope international bike industry distributors will be interested to make substantial orders which could be drop-shipped direct from the factory. Drop shipping would be much to complicated for individual sales, I'd need to charge more for the much greater communication and handling effort. But "where there's a will, there's a way". Somehow international sales will happen, I just don't know how yet. Stay tuned!

    Yes more pictures will be posted in time to the website. The spoke holes are drilled with enough room for nipple direction "float". One reason I decided on a deep parabolic rim wall design besides maximum stiffness and strength, was for room for alternatively using internal nipples such as ENVE rims are limited to, for a stylish look although that is heavier and very inconvenient for adjusting spoke tension after building. These thick spoke beds with the parabolic rim wall design do not fail in testing, spokes break first. The many layers of crossing direction UD fiber and thickness are effectively as strong as much more labor intensive molded holes. Although the molded holes may reduce weight for the strength as much as 10 to 15 grams per rim. ENVE does have a patent filed on this technique.

    The rear 135/142mm trail hubs have flanges that are about 90mm wide. The spoke holes are wide enough for sufficient nipple/spoke direction angles. I see no problem with using wide hubs for fat bikes, or 150mm DH rear hubs.

    I'm working on getting international sales to happen. A Euro distributor could have a huge demand from Enduro riders.

    I can't take the time from my regular job to get to Europe this year.

    Thanks for the suggestions. In my 30+ years trail riding experience, I've observed that manufacturing defects normally show up in the first month or six months or so of frequent riding of other components and rims. And the factory won't warranty more than 1 year. However, I could consider a longer defect warranty at my risk, I just don't want to get into what is a factory defect argument after years of heavy duty use as intended. Personally I think more than a year defect warranty is hype, except for metal fatigue and then 3 years seems more than a reasonable fatigue failure expectation for higher end.

    I'm taking your crash replacement suggestion in consideration, it would need to be a higher price, the current price is below my costs. I should not loose because you crash or run over the rim with your truck. I expect crash damage that fails one of my rims would kill the rider! These rims are "overbuilt" according to an expert professional carbon-fiber design engineer.

    It is steep for me too. But like cranks or dropper posts and other major components, the best cost more to produce and need to be priced to cover the higher costs and eventually profit.

    Consider getting one wide rim for the front. Later a rear. The front end with narrow rims (I feel 30mm carbon rims are narrow), tends to wash out before the rear when hard cornering or up switchbacks. When I ran metal rims, I used a P35 only on the front, and a 28mm rear rim. Going back to narrow 30mm when I tried carbon rims was a major let down in handling performance and stability and directional control over rocks with much less side slip, so I began research on this wide rim project. And the rear wheel tends to follow the front. However, with the wide rims front and rear, the rear brake modulation is more powerful which makes the front tire grip better too in corners. The front end wash out is not really apparent with real wide rims front and rear, the same tire grips and rails in corners so much better.

    Well my rims are currently $279 each for the first 10 sets ordered in each size, 29'r or 650b, which is $558 for a set plus $20 shipped anywhere in the US lower 48, add $20 more to Hawaii and $30 more for Alaska. International is too expensive to reasonably ship with cost quotes of $350 for the "oversized" packages from all the major carriers, so I'm hoping distributors will be interested to work out alternative production order shipping direct from the factory.

    After the limited count Grand Opening price, it will rise, but probably no higher than $20 more per rim at first. That is until dealers and distributor buy in quantity (I hope!), then I'll have to maintain my direct order price at the full MSRP to support room for discounting to them, enough for both me and the resellers to make a buck, and room for them to discount below MSRP.

    Noted. I do need to add the failure force test data to the web site. Only a few have ridden them so far with confidentially. Maybe they will post their impressions, they confirm with me my own riding impression of incredible handling, stability, and traction performance improvement without sacrificing any weight advantage compared to light weight 24mm wide metal rims.

    And I was wondering if the copy font was too light, I will darken that and make larger (I also wish Dirt Rag and Bike Mag would increase their font size, maybe not have so much white space between the character rows.)

    Well the WIDE is what I am hyping! Maybe I have over done it : ) The wide-ness is the major performance advantage of these light weight rims optimizing just about any trail and DH tire, besides the easy tire installation without levers, secure bead locks for tubeless preventing burps, stiffness, and incredible rock hit durability, not to mention the great look of the deep rims on any bike.



    Thanks everyone! .... I'll check back when I can come up for air again and relax here.

    Was wondering where you'd disappeared to Derby, but great response back to everyones questions.

    On the "Who's ridden them" it would be a very good idea if the people who have ridden and tested them did do some reviews/write ups of their experience using them and what other rims/wheels they've used, what bike type they were used on and their style of riding.

    To Font size, that's not an issue these days with current browsers, you only need to use CTRL+/- to change it, so wouldn't worry about that. As to font colour, I'm quite picky since I always believe the easiest/simplest solution is normally the best. Hear you on pushing the WIDE, but honestly, bolding it would make it stand out, but not as much as putting it in orange IMHO, but what do I know

    Now all that aside, these have loads of potential, was looking at carbon rims but wasn't too impressed with the current offerings width wise. Personally can't afford any of these yet, but do plan to get a pair of Blunt35s to lace up and give a try on the Prime and rigid KM.

    FYI, for international shipping, not sure about other places, but from here we can get freight forwarders in Miami who consolidate shipments to fill a container or pallet and charge a pretty reasonable rate, especially compared to the OS charge those couriers charge. They also handle the customs and all that other fun crap.

    I'm not sure if you've had to use the crash replacement on your Rovals yet, but for my Roval SL's it was $550 per rim, plus the cost to rebuild. I got lucky and it turned out to be a manufacturing defect, which Specialized just took care of (they do have a good warranty, can't argue with that), but I just wanted to point out that's a pretty steep crash replacement cost, and the initial cost is almost 2x these too.

    I do find it interesting that he went with the "no bead hook" rim design, ala Specialized. I guess there's something to it.
    Fall in Fruita/GJ. F' yeah! Lunch Loops are riding sweet and so is everything else.

    29 x 35mm carbon fiber DERBY RIMS Grand Opening

    Complaining about the warranty is ridiculous. Specialized is a billion dollar corporation and Derby is a privateer doing countless hours of leg work for a minimal profit on top of his 40+ hr a week day job. I'm happy there's any kind of warranty, period! Specialized could give away 1000 sets of Rovals tomorrow and it would barely be a blip on their accountant's radar. Derby probably won't sell a thousand sets in a year(no offense).

    Rant done...

    Thanks for doing this, Derby. I love the design! Exactly what I would've designed for myself if I had the balls to do it. I bought a set

    While i agree that it's great that someone felt strongly enough to follow their dreams and produce a product they wanted and thought there is a market for (think Derby is right in this regard), I cannot agree that just because you're a small company or one man operation that your product should be any less or not have the confidence to stand behind it for a reasonable time frame, i.e. warranty, than a big company - If you're going to try and play with the "BigBoys", then expect to have to produce similar or better product and expectations of said products.

I'm happy there's any kind of warranty, period! Specialized could give away 1000 sets of Rovals tomorrow and it would barely be a blip on their accountant's radar. Derby probably won't sell a thousand sets in a year(no offense).

    Rant done...

    Thanks for doing this, Derby. I love the design! Exactly what I would've designed for myself if I had the balls to do it. I bought a set
    If someone would care to, if there's no bead seat, then how does the tyre bead "seat" and stay on the rim?? Maybe I'm missing something simple, never claimed rocket scientist status so would appreciate the smarter ones explaining.

    I currently ride a set of carbon rims. They weight around 390grams. The OD is 30mm. I am not quite convinced that the derby rims are for me. I totally understand the stiffness angle and will agree that when I compare an aluminum rim to a carbon rim, there is no comparison. However, you have to weigh the advantages of light weight and the width/stiffness and I personally think that these are a little bit too heavy. One of the things that 29ers are plagued with is a heavy wheel set. In my mind the most important thing to make a 29er come alive and be a fun bike is to reduce the wheel weight. These may have the advantage of being super stiff, but it loses by adding too much weight and I believe the bike is not going to be a lively and fun to ride.....that being said, other riders may weight the stiffness of the rims greater than the weight. Just know what you want to get out of the product and buy the right one...

    29 x 35mm carbon fiber DERBY RIMS Grand Opening

    YaMon,
    I wouldn't sweat 50gr too much. While I see what you're saying, if 50gr is a big deal, then these probably aren't for you anyway. How much does an ENVE AM rim weigh? Yea... The Flow EX, Velocity P35 "AM" crowd will be all over these in a heartbeat! These can actually produce a LIGHTER setup if you ran a lighter tire. I'm scared to run a non sidewall protection, über light tire on my current carbon rims from fear of crunching the bead hook. With the wider, 50gr heavier Derby rim, I wouldn't think twice about running a 100gr lighter tire because I'm not worried about the bead so I could SAVE weight in rotating mass All depends how you work the numbers.

    Lynx,
    The hookless design is just like a car or motorcycle bead. Modern mtb tires have such strong, tight beads, the hook really doesn't even do anything besides being a liability on a carbon rim. Specialized's new Roval Trail rims are hookless as well. It's an old technology being rehashed in modern times since the tire technology can now handle it. Derby has a slight "UST" style ridge(you can see in the cutaway picture on his website) that will keep the tire in the outer side of the wheel. His rim will be the norm in a few years. I see this rim as one of those visionary ideas that is far enough ahead of it's time that it will take a while to catch on.

    Ditto. More specifically, trying to figure out if the rims would be compatible for cyclocross using open tubular/clincher tires and latex tubes? While I have a couple sets of the LB XC carbon 29er rims with Specialized Trigger Pro tires and latex tubes for gravel/light trail use, those rims have a slight 'hook' on the inner bead and I am concerned that the lack of a 'hook' on the Derby rim bead might not be suited to the lower pressures with relatively narrower (32mm) cross tires.

    derby,

    First - a correction. On your Buy Now page you list the specs for BSD as 584mm for both 650B and 29". I think you want something around 622mm for 29". Probably a copy/paste oversight when the page was created.

    Second - hats off for taking on this project! I've been a fan of wide rims for almost a decade so this is really great news for me. I hope this really takes off. I'm not currently in the market for a new wheelset, but when I am (probably early next year), this will probably be the only rim on my short list.

    Thanks and good luck!

    29 x 35mm carbon fiber DERBY RIMS Grand Opening

    I just got mine today! They're BIG!!! Pictures and numbers don't do these things justice. An old Flow literally fits INSIDE the rim bed of the Derby! I threw a tube and a Dampf on just to see what the volume was like. Massive. Tires fit very tight on these guys. My Dampf is used and has never been right enough to need a tire level to mount...until today. The bead seat is very tight and the UST style ledge makes getting them off a bit harder, which I find a good thing. The hookless design is nothing to be afraid whatsoever. Tires aren't going to roll off these guys or burp

    The finish is MUCH better than my LightBicycle AM rims. A few imperfections here and there but it's matte carbon so it's to be expected. They'll be trashed within a few rides with me at the helm anyway. I couldn't be happier. Once my new hubs show up, off they go to Chad at The Barn There will be pictures...

    Id love to see some pictures of tires mounted on them, say next to a picture of the same tire on a typical narrower rim, something maybe in a 2.35 29er?

    OK Dude, since you're the first the task falls to you, as asked, pics of the same tyre mounted on these and say some LB ones and Flows if you have em and of course measurements.

    As to ragging on Derby, that all part and parcel of having the cahones to start up something like this and feedback/criticism does help, once it's constructive and I think it has been. You can't blame people for questioning about warranty etc in these tough times, when a set of these rims will set you back the more than the cost of a decent wheelset like Pro2/Flows. I'll say though, if I had the coin I'd give them a go as I like wide and light would be nice, but it's the stiffness I want more than uber lightweight.

    It would be interesting to test all the carbon rims for stiffness. However ...keep in mind that you could have a rim that tests stiff and you would never be able to reach that limit....so in the end it would be a waste.

    Eg...I sell a hurricane screen that the Building Code says the connection have to pass 400 pounds of pressure. Brass grommets pass at 600 pounds. There are 2 other connections that pass at 14,000 and 15,500 pounds of pressure.....at that pressure the house will not be standing anyways....

    So here is something interesting. I have 2.25 Schwalbe Racing Ralphs mounted 30mm wide rims. When I measure the distance between the edge of the rim and the edge of the tire, it is 10mm. Does this mean that with the same tire mounted to a 35mm wide rim, the distance will be 7.5mm ??

    I'll get some pics and measurements tomorrow. They showed up about 30 minutes before I had to leave for a business trip so I didn't have any time to get pics/measurements done properly

    This is really exciting. Thanks for taking the plunge on this so we can have sweet toys to play with. I hope this works out for you (and us). Budget won't allow me to pull the trigger on these currently, but if things are on track when it does, these will be on my next wheelset.

    Hey Muzz, since DFYFZX was so inconsiderate, why not, when you're purchasing your rims add another 2 and send to me, I take excellent photos and would most likely get them before you anyhow Also have a decent selection of tyres to try on them, so definite win/win for ya and I mean seriously, like the wifeys gona get any more bent outa shape for you spending dosh on 2 more rims

    I just brought another set off I9 wheels & she has pinched them, So I am a set of wheels down.

    The joke is every time she goes away with work I buy a bike or something for a bike. Last week she had to work Australia & I brought a bike & the I9's.

    In 2 weeks time she has to work in England for to weeks, Then 3weeks after she is back she has to work in Australia for a week & then back in new Zealand for 2 weeks & then she is Working back in Australia for a week.

    So it may be a bit hard to keep up my record of buying things I shouldn't.
