    26in chinese carbon all mountain rim

    I really enjoy the 29er chinese carbon rim thread but l didnt see anything for all mountain chinese wheels or rims. I'm looking for some 26in carbon all mountain rims that need to be wide, pretty light and strong to go on my Tracer2. Going through all the Asian carbon stores is big undertaking. That, and l dont fully understand everything about wheels. Are all the rims pretty much for xc if not can someone point me in the right direction

    Well the company that everybody is buying the wheels from in the 29er thread also makes 26er carbon rims as well.

    26er MTB carbon MTB rim clincher - light-bicycle

    That is the regular 24mm wide 26er. They are also in the process of producing a wider 26er that will come in at 30mm wide (external), 23mm wide (internal), and 23mm depth...which is wider than the ZTR Flow. Not sure on the weight of the wider rim since I'm still waiting for a reply from Nancy.

    Do you know what the internal width is on those rims? Price and weight looks reasonable. Found the 29er rim thread. Has others used the 26er version?

    I see there's no inner ridge to keep the bead in place.

    Here is what Nancy sent me for the wider 26er...she also mentioned that the weight will be right around 370-380g.

    Impossible to tell, as these are not in production yet. However given that a Mavic 823 weighs over 600g, it's a bit hard to imagine that a sub 400 carbon rim is intended to compete in that usage category.

    Check the 20 page thread in the 29er section for some short term ride reports.

    Yeah, I have been, I actually want to build up a set of normal 29er rims for my 29ers

    But currently I am planning to build a set of DH rims with Stans Flow or DT swiss 500, so I wonder if these would work. The real question is what would happen if you hit something hard enough that would normally dent a aluminum rim.

    well, pound for pound, properly laid up carbon will be stronger than aluminum in pretty much all aspects, too many variables here to know though if these will adhere to that, i dont think id risk it on DH as the risk far outweighs the reward...light-bikes can build the rims up beefier for heavier riders upon request, so that might be an option if you are brave
    enve has a DH rim coming out soon that has been quite durable in testing, much moreso than aluminum DH rims and weighs in around 475g...they will assuredly be better than these chinese rims, at a major cost penalty

    I have seen Enve rims fail. One rim that a pro DH rider was using broke, with the bead hook chipped off. An AL rim would have bent at that spot. Granted, this was at Bootleg, so not too many rims last there.

    Enve DH's are $1000 per rim. It's a joke.

    For DH, if you are going to use light rims, you are better off using something cheaper like Flow and replacing it every season or more.

    read the article i linked about the testing they did, may be one you were talking aobut:

    During the 2010 season, the Syndicate’s first on the carbon rims, they replaced 53 wheels, which was down from a reported 180 wheels per season when the team was on alloy. In 2011, the team had to replace just 11 wheels.

    Of last season’s 11 broken wheels, not one lost air pressure or warranted their rider to slow before the finish line. “They were cracking hook beads,” said Schiers of the failures

    Article on Enve DH rims (including weights) are here: ENVE Launch DH Rims And Wheels - BikeRadar

    So will a sub 400g rim be suitable for DH? Especially when the manufacturer has stated a rider weight limit? The answer should be self evident.

    Yeah ENVE, is a little too pricey for me. I love high end stuff, but when cost is 1000% ($600 vs. $60) greater then a comparable aluminum rim that weighs about the same, I think there is a better way to go.

    But like it has been said, if the carbon fails it's one of 2 ways, it's a crack and it's not a huge deal, or it is a fracture, and all hell breaks loose in your world at that moment.

    That profile doesn't look like it'll be tubeless compatible at all. The profile looks exactly like their current narrow 26 rim profile and the current rim is not tubeless compatible according to Nancy when I inquired about them.
    I hope they make the profile like the wider 29er rim.

    Per Nancy just a few minutes ago:

    "Hello sir,

    It is tubeless compatible,but we are doing the strength testing & also the outlook checking. To make them perfect.

    Thanks,
    Nancy"

    Agreed,
    I have the popcorn and wine in hand watching this thread. If I could get a sub 400g 23mm wide (internal) rim for my new Lefty build I'd be thrilled. I'd even go as high as $200 for it.

    Looks like March 5th is the ETA for the wider 26er. Nancy is checking back with the engineer to get me an up-to-date cross-section.

    What's the profile of their XC rim? At 330gr, it could make a killer rear wheel.

    Can you explain or draw what the profile needs to be or how it needs to change for tubeless and why that is? Thanks!

    Would something like the Bontrager rim strip work, granted it would add weight but, doesn't it have a beadlock on the rimstrip.

    See the flat ramps on the sides? Holds the bead in place so it can seal.

    Let me see if I understand you.



    So what you are saying is the red shelf is where the bead of the tire sits when deflated, with the bead approximately located where the blue dots are, you then inflate the tire and the bead slides up the sides of the rim and hooks under the lip there where the green dots are?

    If this is the case why won't these Chinese rims work? It would seem that it might be harder to get a tire mounted but not impossible with a compressor and some soap right?

    I see, interesting. So for it to be UST or UST compatible it has to have those ramps and that shape for the bead? What if it's not UST but "tubeless compatible" like the enve rims?

    Thanks!

    I guess specs are kind of all over the place for now.

    This is what she told me yesterday.

    "The ERD will be at 537mm to 539mm, i still haven't got the finianl one from our engineer leader, they will inform us once the rims are ready to sell."

    I sure hope the rim profile comes out with the UST platforms/ramps built in. They are going to miss out on a lot of sales if they look like the earlier picture shown.

    Subscribing. Interested in the wide all mountain. In the 29er thread on the same topic, a guy was considering ordering a rim without the outer holes drilled to & use a magnet to pull nipples (with a steel threaded shaft fitted) through from the valve hole. This would make a well sealed tubeless rim.

    Per Nancy:

    "The rims are ready, the engineers are preparing the pictures and datas for this rim, then our website administrator will upload the pictures on our website.

    Thanks for your follow up. It can be finished soon."

    Excited to see what the end result came out to be.

    That's how Fulcrum (road wheels) does it on their 2 way fit road tubeless wheels.

    They do pretty well, but I won't buy them for that reason. When you buy a Notubes rim you expect to use std tires with sealant.

    I want a rim that I can mount UST or tubeless ready on without issue. The Notubes rims don't do nearly as well with ust tire beads

    I wonder what the weight limit is on the wide 25ers; I read somewhere that the "normal" 26ers had a 190lb weight limit.

    the 29er wide rims had a rider weight of 95kg (210lb), but could be built up with extra carbon for heavier riders
