    Wide in front. Narrow in back?

    I'm seriously considering purchasing a pair of these "Nancy" wheels. I have a question though: I like riding a narrower profile tire in back, say 1.95, and wider up front. Would it make sense to order a mismatched pair, i.e. a wider (23mm internal) upfront and a narrower (21mm) rear? Or will I burp air under hard cornering? If I go wide on both, then what's the narrowest tire profile I'll be able to run for my back tire?

    as for a 1.95 tire on the wider rim, i have no experience with that as i cant imagine ever wanting a tire that small, did find this chart though fwiw, and it looks to be ok but who knows how it will handle
    dont see any problem with mismatching them either if thats what youd prefer

    I'm using a 2.0 Spesh Captain on the wide rim as my rear wheel and like it. It gives a nice profile.
    Faster is not always better, but it's always more fun

    I took these rims out for their first trail ride. They were just AWESOME! I was able to climb easier with them, and the nice round tire profile was super nice in terms of good traction.

    Overall, I'm very impressed with their quality (not perfect, but for the $$). My Nomad carbon now has the right amount of weight/strength balance

    I didn't end up using my Bontrager strips, if anyone wants to buy the pair. They took me a while to hunt down.

    UST compatible?

    I've scoured this and the 29er Chinese thread but can't find the answer to this question:

    Has anyone mounted a UST tire (not tubeless ready, but actual UST) to the AM (34mm internal) version of these rims? From the rim cross section it doesn't appear to match UST spec, so will a UST spec tire mount to these rims?

    many tubeless ready tires have a UST spec bead, just not an air-tight casing.
    user 'zorg' seems to be running S captain 2bliss on his with bonty strips.

    Missling bead lock?

    Macming, forgive me for beating a dead horse; but how is it possible as based on the profile there appears to be no bead lock? How does the UST tire "hook" for the air tight seal without the bead lock on the rim? That's what worries me most, as I plan on strictly using UST tires.

    i haven't followed that closely but weren't there two drawings? - one that was incorrect and one that was corrected that had been emailed to some people who asked directly about it.

    I was concerned about the lack of bead lock myself. In fact, I purchased a set of Bontrager Rythem strips to correct this.

    At the end of the day, my UST nobby nics mounted supe easily. The bead popped into place as I aired them up. I left them at 30 psi, and the tire/wheel performed beatifully over the last ride.

    Considering how cheap these rims are, I have no complaints.

    Are these the rims for "heavier people" or just the regular wide rims?

    there really isnt a distinguishment between the two, they are the same rim, one just layed up with more carbon...they will be using the same molds so its just a matter of when you placed your order it sounds like, regardless if you asked for the HD rims or standard

    Good job! Ordered mine today!

    I have a new set of the very light American Classic Disc hubs and just paid for my set of the wider 26 inch rims today ($304.00 with logo). Mine will have the matte finish 3k with their name in clear high gloss like ENVE does but instead of the blue background it will be red. I will be using DT Competition spokes (1.8-2.0) with red ano nipples and AC red ano tubeless valve stems. They should look pretty awesome when they're built up before the end of next month.

    Can someone educate me on the process involved to get the logo done? What colors do they support? What dimensions do you use? What file format do you send them? I'm most interested in paying the bit extra for logos but the process seems quite obscure to me.

    I did the logo in clear to contrast the matte finish and the blue behind the logo will be red.

    Impressive! Although I would have gone with "NANCY COMPOSITES" myself (kidding).

    Did you actually send them this image, or did you create a graphic file that accounted for the rim curvature and such? If so do you mind sharing how so I can recreate in Illustrator (using different words of course)?

    UST compatible?

    Just received this cross section diagram from Brian. Aside from the small ledge this looks like it might work ok with UST spec tires, which is what I plan on running. Thoughts?

    Update from Nancy:
    Sorry for the late reply, the rims will be shipped before the end of this month. The first production has been started last week. And will do sanding & painting these days. I will do QC check before shipping.

    Bontrager symmetric Rythm strip will give you the bead lock you're looking for (wide rim only). It weighs next to nothing and works beautifully. I also suspect (but only time will tell) that the Rythm strip will hold up better over time than the equivalent Stan strip, while being much cheaper. I run a 2.0 Spesh Captain 2bliss tire on the rear and a Maxxis Advantage 2.25 on the front with Stan's goop without any problem. I used my compressor to air it up and the bead set quickly. The Captain took 2-3 rides to seal well, and now holds air really well. I currently run the tires around 30-32 psi (probably 175-180# ready to ride) on an Intense Carbine. I'll experiment with lower pressures over the next few rides.

    One more thing: I had to use 3 tire levers to set in place a new Captain tire, and it was a real pain. I only needed one for the used Maxxis Advantage.

    you ran the flow strips prior to the bonty strip, right? another poster showed the bonty didn't meet the bead fully - i assume yours are the same and how did the flow strip fit compared to the bonty?

    I ordered a Flow strip but never used it since the Rythm strip worked so well. I don't quite follow the "UST bead being too far" comment. The edges of the strip are lined up properly with the inside rim wall as far as I can tell, so if the UST beadlocks are too far, that'd be due to the Rythm strip being inadequate. Then again, I'm no tire/bead/wheel specialist, just your average Joe rider. For what it's worth, I rode the bike in the mountain where it's fairly rocky a couple times, and the rear tire never burped (front wheel wasn't ready yet then).

    I ordered yesterday a pair of 26" carbon rims (not the wide version) and today I got this ETA from Nancy:

    Hello sir,
    Thank you so much, your rims will be finished in 8days, i will mail you the tracking number when the rims are finished.
    Thanks,Nancy
    I must tell that I never had such a quick reply and support from any online company in the past. Nancy is answering me in less than 10 minutes each time I'm sending. Now lets hope it will really be 8 days...

    do your strips look like this when mounted?





    or is there a gap between the strip and the bead hook like this?

    Looks like the first. I don't remember seeing a gap, then again, I wasn't looking for it either. I'm a simple guy. I put it on, I installed the tire, I aired it up and it stayed inflated. I was happy.

    This whole ERD thing needs to be checked. Is it 536 or 530? Are you guys who say 530 sure you're measuring correctly?
    I have flows now and would like to swap over since they also have ERD 536

    you should measure it yourself once you get them, especially with some of the manufacturing hiccups that have come up, theres a chance that there may be some differing measures on these rims, though a 6mm delta seems quite off
    ...that said, they list 536mm on the website for the wide 26", and i believe the guys ordering the 29er version have come up with similar measures as the websites listed ERD

    I posted the second picture. If you looked at the rim directly, there is the same amount of gap between the rim and the strip. I wasn't too comfortable with it, and the strip made the rim too tight to mount a tire.

    My rims were definitely not 536. The excess spoke showing on my straight pull Industry 9 wheels is much more so than 1.5mm (I had DT 5.1ds with 539mm ERD before). Both my LBS and I came to the same 529-530mm measurement.

    If you don't have spokes already, I'd wait until you got the rims before ordering spokes.

    Perhaps it was a manufacturing defect. I probably should've waited for the second batch

    wow, those I9 spoke/hubs are way more versatile than i thought. I never knew you could use the same spokes for rims that differ by 10mm in ERD. (I probably should've bought that I9 wheelset that was up for sale a while back)

    So, do you have an extra 5mm of spoke showing through at the hub?

    Do those I9 spokes need nipples at the rim end, or is there a thicker bit at the end - kinda like a built in nipple?

    Did you measure the ERD with these i9 spokes/nipples? How about stock standard nipples/spokes? If so, did you get the same ERD? From what I have read, some of the other nipples sit a little differently in some rims, making a few mm diff in the ERD measurement.

    If in doubt, measure it yourself. Check online, there are several means to measure it.

    As I stated above, I measured mine at 537 mm, close enough to the 536 mm. Measured it myself, bought the necessary spokes to build my wheel and it came out right on.

    Good luck with that.

    Any riders here tested this rims at downhill or any really rocky terrain ?
    Will it hold?

    First of all I found it very difficult to measure ERD precisely. I used the techniques from a wheelbuilding PDF I have but I still got it wrong on an old rim.

    Second, I have Comp and Revo spokes matching my Hope Pro2 and Flows which would be nice to use over again. If I could do that it would make this deal more attractive.

    I sort of doubt that it could be quality problems making the rims differ by 6-7 mm in diameter. I mean thay have solid metal molds they make these in. They can't differ that much if they dont switch molds. I'd be more inclined to thinking it's measuring differences.

    Spending again...

    Because of this "stupid" thread, I have now ordered the wide 26" rims... Also ordered the MTB252 rear hub from BikeHubStore. I went with this hub because it has 42 POE, good for my singlespeed. This will be the first time I will be building wheels. I've done pretty much everything on my bikes, except build wheels... damn MTBR.....

    See attached image. I broke a piece of the freehub body while trying to change my bearings yesterday. I took this picture to source a new freehub body from I9.

    The I9 spokes have a built in nipple and thread into the hub.

    So, do you have an extra 5mm of spoke showing through at the hub?

    Do those I9 spokes need nipples at the rim end, or is there a thicker bit at the end - kinda like a built in nipple?

    Did you measure the ERD with these i9 spokes/nipples? How about stock standard nipples/spokes? If so, did you get the same ERD? From what I have read, some of the other nipples sit a little differently in some rims, making a few mm diff in the ERD measurement.

    As I stated above, I measured mine at 537 mm, close enough to the 536 mm. Measured it myself, bought the necessary spokes to build my wheel and it came out right on.

    Good luck with that.

    Second, I have Comp and Revo spokes matching my Hope Pro2 and Flows which would be nice to use over again. If I could do that it would make this deal more attractive.

    I sort of doubt that it could be quality problems making the rims differ by 6-7 mm in diameter. I mean thay have solid metal molds they make these in. They can't differ that much if they dont switch molds. I'd be more inclined to thinking it's measuring differences.

    This mornings email from Light-Bicycle

    Hello

    I am sorry to say but I'm afraid not. The 26er rims have not come out yet. We are now trying our best to manufacture. They should be shipped at the end of this month. We are sorry about it.

    Best Regards,
    Brian from Light-Bicycle

    Asked them about 20mm F & 12x142 R 32H on the wider rims, $540, def sounds reasonable, if I blew up another ex 500, I might just pull the trigger..

    From LB:
    "The rims are finished, one rim has some painting pollution, and i have asked the production line to repaint, we can ship them out to you these days."

    no idea what paint pollution is, i guess dust/particulate got on them or something...which is of no concern to me if thats the case

    I guess it must be some small paint/clear coat particles that have fallen over the rim. Or someone just drop his coffee right on the rims

    Hello,

    The wider 26er rim mold has completed updating. Late week, we sent out two rims to an earlier-ordered customer and we will ship out more from this week. Your rims would probable be shipped in one week, according to the order sequence.

    Am I right in guessing it has been about three months from order to ship for you? I ordered a set over a month ago (because of this damn thread), wondering if it will take another couple months to see the rims.

    it has nothing to do with when you ordered
    they had issues in the beginning that they needed to iron out, and they stopped production...so id imagine that they will be shipping all backorders shortly

    This is almost the finished desidn that I am having done on my wheels. I told them to eliminate the white in the background and to make it only red. The actual name is not any color but high gloss clear so it will pop in sunlight.

    Ive been lurking around for a while now but this is my first post.

    I emailed Light-bicycle yesterday about the rider weight limit of the rims and "Nancy" claims that the 360g-370g wheels have a rider weight limit of 140kg, thats roughly 308lbs. "She" also says that the beefier version, 390g, has a rider limit of 160kg or 352lbs. So their beefier rim is 5g less than the ENVE AM rim. She also sent me a cross section that has somewhat of a bead lip making them far more suitable for tubules.

    I have a question though for those of you with these wheels. Have any of you taken the new wider rims off any sizable drops or jumps? Say 3'-5' in height? I ride aggressively and hit every jump on a trail I can, and weigh 230lbs, so I am wondering if the 370g rim would be fine since I am 70-80 lbs under the limit plus these would go on a 6" travel bike.

    I have SLR's on my stumpy now and have not had any issues with them and these are supposed to be much stiffer and stronger than the SLR's.

    If you weigh 230, do drops and ride aggressively I would definitely go for the beefier rim. It's 40 g difference. Remember that these are cheaper chinese rims which cannot be compared to $1000 rims. I would have some margin

    Ok i get that these are chinese rims but they are no less quality than the more expensive ones right?

    When I worked at an outdoor store in college we had a 45% profit margin on products so lets use that as an example:

    If I go to a bike shop and buy 1000 rims that means the shop probably paid 550-650 for them, and the manufacturer probably made 300-450 on them when sold to the dealer. So using this example I would assume that if light-bicycle went through US distributers these rims would probably sell for 1500 for a set.

    Yes that is cheaper than the 1800-2400 price we see on name brands but those are name brands and want to make more money to pay for all the R&D.

    The reality is something like 80% of the worlds bikes are made in the FAR EAST and Light-bicycle probably makes frames and rims for several companies that are based here in the US or Europe. I know that there is a lot of chinese knock off crap out there but those are usually boot legs and these rims aren't bootlegs. Plus add the communication that light-bicycle does so well at and I am inclined to think these are at least 80% as good as say ENVE rims

    I figured I would go with the beefier rims. I just hope they dont end up over 400g in weight.

    i dont think the quality is an issue, and id guess 80% of Enve is probably a fair estimate (maybe even conservative?), one of those hard to determine values without some destructive testing...when you throw in bang for buck though, its hard to imagine Enves being 6-7 times better than these rims
    also dont think 3-5' drops are anything to worry about, especially with the beefed up rims and 6" of travel

    Agreed, I would just like to see some more earlier adopters input before I pull the trigger. But the price is just so damn cheap that I may be willing to be an early adopter myself for 280 bucks. I mean if it works out I will feel like the luckiest SOB on the planet, and if it doesn't the rims still have a 1 year warranty and only cost 280 for the set so its not like its a huge blow to my bank account.

    If I do buy them I think I am going to use that new Kappius Evolution Hub with 240 POI! With the money I am saving on the rims I think it would be well worth the cost for the hubs.

    Bit the bullet and ordered two sets (one 26er and one 29er) Bryan emailed me saying due to production backorders, it would be about three weeks before they are sent.

    Fingers crossed he is working on the "under-promise-over-deliver" philosophy. I have a three day stage race on June 30-July2 that I would really like to have them for but I guess, I snooze, i lose.

    Unless you want a light wheelset or your current rims are 400grs or less, 400gr of a CARBON rim is not bad. Yeah, it will be heavy but pretty much bombproof.

    This thread is making me to hit the 'buy' button .... I just received the email from Nancy on the design on the rim. Looking great. Intend to mount American Classic hubs with it to save some grams.

    Just like to check with those who got it in hand
    How is the ride ?
    Any mounting issue with Tubeless tires ?
    What u do not like about it ?

    not many people have received theirs yet because they had manufacturing problems and had rework the mold, the few that have received them from the original batch have posted about them in this thread already, if you havent read it
    you will have to wait a couple weeks for reviews as they are just shipping out now for the people who ordered them a few months ago (picking mine up tomorrow from the post office, and then will be probably 2 weeks before i have them built up) or go read the 29er versions mega thread

    I'm running mine with tubeless tires. The rims are super stiff, and accelerate like crazy.

    I didn't think much of the rims until I hopped back onto my XC bike with 819s. There was a huge amount of difference in stiffness. It wasn't even funny.

    Buy them and you won't regret it.

    More Stiffness = more Butt pain :P
    Can I say that I need to pump more pressure on my rear shock to accommodate the stiffness from the rear carbon rim ?

    one more thing - I'm using NN 2.2 now . Will it be too small for the 30mm wide rim ?

    I've slowly started saving my pennies for a set of those rims...

    Might do the move for next year, but I'd like to first see some solid feedback from a few months of use of those rims from the early adopters. I know this isn't mega $$$, but for a student that's a lot of money for a set of rims. I'll be using them on my GT XCR bike, so a FS XC bike and since I'm fairly lightweight at 120 and never really destroyed bike parts even riding hard, I'm thinking about a low spokes count build with the narrow 26" rim.

    I won't be running anything bigger than 2.1 tires and probably won't even go tubeless, but I'd like to see if the narrow rims could handle ghetto tubeless setup with standard, non tubeless folding tires.

    And does anyone as a link or reference chart about the different carbon fiber wave/finish ?

    DO NOT pump more pressure into your shock! Set your pressure according to manufacture weight limits or 25-30% sag depending on your bike. You will ruin the small bump compliance and the handling if you pump up the pressure in the shock.

    As far as tire width is concerned a 2.2 would be fine on that rim but a 2.3-2.5 would be best

    Just for reference the ENVE DH rims are 475g a piece. The beefier version of the chinese rim only weighs 400g so these rims are not suitable for DH. I believe they are suitable for AM though as the beefier version rims weigh the same as ENVE AM rims..

    there are far more variables that determine its suitability for usage than just comparing weights

    FWIW, I'm running a Maxxis Advantage 2.25 on the front and a Spesh Captain 2.0 on the rear, both tubeless using the Bontrager Rythm strip. Very happy with the wheels so far.

    First off I need to mention, I have zero experience with carbon rims, so I don't really have a baseline of comparison for these.
    The exterior finish is good, and there are no irregularities. The bed seems solid as well, with minimal sanding spots, no noticeable areas where filler has been used. All the bead hooks are properly formed and fairly uniform (the only variations are where a couple of rim segments meet, but they are nominal). One of the valve holes on the interior looks a bit irregular and is prob gonna need to be opened up a little more, but id rather it be under drilled than over drilled I suppose. Overall I am very pleased with these rims, construction is as good or better than I expected from following this and the 29er thread (again no carbon rim experience) and they feel nice and light/stiff unbuilt compared to past experience with velocity/stans.
    I am one that thinks weight weenies are a bit ridiculous and have no intentions of weighing these (no scale). I ordered the standard layup that is claimed to be in the 370g +/-10 range fwiw, and if they are 400g it wouldn't bother me.

    Here are some camera phone pics i took on my lunch break, not great, but whatever. If anyone has any special requests, I can try and accommodate with my point and shoot.







    also, i got a seat post to try out

    Can I say that I need to pump more pressure on my rear shock to accommodate the stiffness from the rear carbon rim ?

    one more thing - I'm using NN 2.2 now . Will it be too small for the 30mm wide rim ?
    No worries. By stiffness, I think most people by stiffness sideways. Wheels don't tend to flex much vertically.

    I'm running the same 2.2 NN tires on these rims. They work great and I love the tire profile.

    Also, I have a NomadC with a CCDB coil. The bike is PLUSH regardless of the wheel choice

    Nice. Wanna trade? j/k

    I may get a second set after all the back log has cleared up. Donno what I want to do yet. Maybe I'll switch the rims around this time.

    So your rims are unlike the most recently posted cross section, which has the bead shelf rising before the center channel.

    Great Customer Service

    After I received my tracking number from Light Bicycles, I had issues using their website (verification code in Chinese) and mentioned it in an email back to "Brian".

    Since then, "Brian" has been sending me daily updates on my package's progress via email. (I did manage to navigate to a page on the EMS website with a non-Chinese verification code).

    Despite the delay, I've been very happy with the customer service. Hopefully the rims are just as good.

    So your bead shelf slopes upwards before the center channel?

    nope, maybe ever so slightly
    i assume what you are referring to is like a ust rim bed, LB rims have never shown that in the profile

    Manufacturing process is everything in composites. Comparing weights of two rims from different manufactures as a basis for durability is pure speculation.

    True but there are not a whole lot of patented or proprietary layouts for carbon rims out there right now so by comparing weights you can get a close idea of how the rims will act.

    Consider bike geometry back in the 90's, you could just look at the numbers and know how well the bike will ride. Now, not so much because of all the proprietary suspensions and patented pivot points and what not.

    .
    Go do some reading on how carbon fiber is made, talk to some composites engineers then come find me and we can have an intelligent conversation.

    From my point of view, I don't think composite frames technology can even be compared to simple composite parts such as rims or stem spacers... Since your rim must act the same way integrally, there is not much "technology" other than finding the lightest and stiffness wave and layout combination. Not like a frame where every inch do a unique action on the bike handling.

    As long as the rims are strong and true, you just have to be concerned that they aren't made out of 80% resins and 20% fibers

    HA wow what is about the internet that makes people act like complete ****** bags like yourself?

    Perhaps I miss spoke. Currently there are only a few ways to manufacture carbon components and they are shared across the industry. Each company may have a specific carbon layup that their engineers prefer but the carbon is all formed in the same way. Thats my point here. Unfortunately I can not post links yet or else i would add documentation
