    Those Ibis seem a little rougher than the Derbys, more like the LB. The Derby cut outs really do look more uniform and better proportioned.
    Although upon closer inspection the Ibis 941 does look pretty clean and uniform.

    shows that all rims from LB have 3k lay up on the inside to improve spoke holes

    No bead lock shoulders on any of these. That 27mm sure is a good looking cross section... but I'm pretty sure I want 35mm, if not 38mm.

    I got another one from LB. A good close up.
    I must say that Nancy from LB has set the standard for before the sale customer service with thorough and prompt replies to my questions.
    Here I asked about angled nipple holes, and her reply... "Currently, our rim spoke holes are straight, no angle. If you like +/-6 degree, you can inform us once you place the order. Then we can manufacture accordingly.

    It is like attached picture. Please check."
    They really seem super accommodating.

    She also stated in her reply..."And for Nextie or other guys, they are different from us. There are quite a few guys emailed us to check this. Please check below statement. If the rims are not from us, we will not offer warraty for those rims.

    Currently, most factories know our rims are popular. So they copy our rim profile drawing, to make the rims look the same. But actually the inside structure is totally different. The layup schedule and the manufacturing process will make the carbon rims with different strength. It is hard to tell all the manufacturing process here, but you know our rims are popular, and we have got high reputation. We are the leading factory in manufacturing carbon rims. Most factories are always looking at our new products and copy the same design."

    That tidbit about angled drilling is new to me, thanks for posting it dimitrin! I wonder if the better spoke/nipple alignment would balance out the liability of the nip heads sitting at kind of a funky angle on the inner wall of the rim. With an eyeletted rim or maybe with washers it seems like there could enough wiggle room and deflection to still spread the load across most of the nip head, but with the straight CF inner wall, I'm not so sure.

    To those who were reading this thread way back when, it looks like LB has upgraded their drilling capabilities significantly. A while back I recall someone saying that theirs looked like they were drilled by a kid with a hand drill and a dull bit, and now they are hitting 6 degree offsets!

    I also found this interesting. They still claim to be a factory, when several earlier posters have argued very convincingly that LB is a trading company, one of many, who resells products made by other companies. It is kind of cute that things have progressed to the point where LB is now warning about counterfeit product, copying their designs but not equaling their quality of layup, whereas a year or two ago we were all talking about if these were bootleg Roval rims coming out the proverbial back door of the factory, and whether or not they were as safe and well designed as the big red "S" products. Talk about a brand building milestone!

    Almost made it a full 3 years, but after heavy use a spoke and nipple pulled through the rear wheel rim.

    Time to replace...

    I have both Derby and LB rims, but had to laugh at the irony of a Chinese company posting a statement like that.

    Very nice to see the angled spoke holes. Wonder when they will offer offset spoke beds. I know there are asian companies making some rims with this feature for other companies.

    one of trading companies told me that their product and LB come from same plant.
    Is LB manufacturer or trading company?
    who to believe ?

    The rims may be coming from the same plant but that doesn't necessarily mean there all the same. Each trading company could be having the rims made to THEIR specs.

    I'm remember the discourse regarding the purchase of these rims. I bought a set of the updated versions. Do you plan to obtain another LB rim? Other than the alloy nipples disintegrating, my ENVEs have held up well. Caught a stick but the rim seems fine.

    Yes, I will be ordering a new rim to replace. I might just do front and rear while I am at it to a bit wider version.

    Do you think the wider rim version, "how wide" will be a problem on your 429c with rear clearance?

    Ok, this may be the last pic. It is from Nextie. I asked for cross section but this is all they had.

    (Cheap) Chinese Carbon Rims?-nextie-rim-pics.png

    They included some clarifications...

    "Yes, all rims are with 3K fiber inside rim channel protecting from spoke holes from tearing.

    Yes, our NXT29H07 and NXT29H06 rims and are with pre-made carbon rings at spoke bed.

    Our NXT29H03 35mm rims are without carbon rings inside, just once to make. (NXT29H03 rim is without beadlock)

    Yes, rims are with continuous layer of carbon fiber.

    Nope, we donít use same manufacturers as Light-Bicycle or Carbon Bicycle.

    Itís Ok. I understand your worries.
    We offer two years warranty on our rims in case they got cracked because the rims quality."


    Well after the pics and clarifications this is what I think I have learned...
    The rims all use 3k on the inside to strengthen spoke holes
    Use of continuous length of carbon fiber during build seems consistent as well
    LB no longer uses rim ring, Nextie still does (mostly)
    LB and CB claim the bead-lock, raised ridges on either side of the rim channel, are not required
    Derby and Nextie claim they make a difference
    Bead-locks may make it more difficult to open the tire up trailside to insert a tube if needed
    Overall rim height varies a lot, sometimes the narrowest one being the tallest...
    CC wide rims 20mm-25mm
    Derby 31mm
    Nextie 25mm-30mm
    LB 20mm-32mm
    6* angle available with LB
    Wide rims weigh more but may ride better with narrower tire than narrow rim with wide tire. Using narrower tire may offset weight concerns yet still improve ride quality. ( I have NOT tested this, but have read it various times)
    CC rims are cheapest, no bead-locks, 1 year warranty
    LB has 1 year warranty
    Nextie 2 year warranty
    These Chinese companies are either setting a new standard for before the sale customer service, or really good B.S. artists.

    questions I would like to know is...
    benefits vs negatives of 20mm rim height vs 32mm rim height?
    to angle or not to angle spoke holes?
    has anyone had to file for a warranty claim and how did it go?

    For me the LB after sales was just as good as before. I received a scratched rim and got an instant reply after i send a picture of the rim + the serial number. A new one is on its way.

    Im using a set of 29er nextie rims 35 wide and 28 deep. Been pretty impressed with them even though ive not given them a proper test yet.


    I know this is a little OT as this is a MTB forum but im looking to buy a set of road carbon rims and i think ill go with nextie again. Theres a build option of having a basalt braking surface, Is this worth going for?

    Thanks

    Yes, go with the basalt, As I understands it, having the basalt reduces the likelihood of issues due to heat build up.

    I purchased a set of 35mm/30mm from Carbon Bicycle on Dec 20th, they arrived in AZ 7 days later. They look to be either the same company (LB) or reside on the same city block...? The price was a little cheaper than LB. They look great, and are currently being built.

    Has anyone built up the new LB 38/31.6 rims yet? I think I may pace an order soon and it'd be cool to see pics of some built up.

    I placed an order for these rims a couple days ago. Expect delivery in a couple weeks. Really looking forward to getting them built up and installed.

    No decals. Told them I wanted UD matte, with no stickers or anything else on them. I got 32 hole rims in the heavier DH version.

    My order of LB 38/31.6 rims took 10 days to arrive in SF Bayarea over the New Year (expected sooner if not for the NY holiday). UD matte 32 holes and no decals. They look really nice. I will take time to build up the wheels.

    Those rims take more beating than the first AM rims. Really happy with mine. Hope hubs are some of the best for function and reliability for a reasonable price tag.

    Spoke Direction - Looking for some help here, I received my new rims this week. I went with 35 mm outer from Xiamen Newtopbike. They came recommended from someone in my bike club.
    I have built a few wheels ober the years but never seen a rim with a "spoke direction" sticker. I am thinking that it has something to do with the lead spoke orienting to the direction of the CF weave, but I could be wrong

    Can anyone confirm what this refers to?

    I believe it means that the holes are directionally drilled. That spoke must connect to the hub flange on that side. DO NOT GET THIS WRONG....it will destroy the rims if you do not....

    Its just an arrow to point out the obvious. It is a "type B rim". Meaning the first spoke hole is offset to the right.

    I think it is directionally drilled, not offset.
    Directional drilling is actually pretty easy to miss unless you know what to look for and remember to check it. It's not very obvious.

    I think meltingfeather has the right idea unless it is visibly offset.

    Question about the different finish options on those rims (the external visible weave):

    Is it just cosmetic, or are some finishes more durable?

    Is directional drilling not treated the exact same way as is offset when it comes to lacing?

    I think with offset you have to install the rim on the hub in a certain direction (the rim is directional), but with offset drilling you can flip the rim 180 and still find the correct positions (rim is not directional)

    I built a I9/ Light Bike 29er wheelset before the hookless rims came out. Original rims were Flows and the ERD matched without a problem.

    My question now is if there is a carbon 650b rim that also matches Flow EX ERD
    (562) so I can re-use the same I9 spokes, just swap out rims, as I did with the 29er.

    Looks to me like the new wide rims ERD is closer to 530/540.

    Thanks for any info!

    I'm not talking about offset rims. I'm talking about spoke hole offset left and right which is correspondingly laced to either right or left flange. Directionally drilled is the same principle wherein the spoke holes appear to be drilled right down the centerline of the rim but when viewed from underneath are angled right or left. The same principle applies when lacing a wheel whether it is offset left or right or drilled left or right. Nothing changes.

    Very easy to check...we have to do it with every rim we ship since ours are all directionally drilled. Drop a spoke and nipple in any of the leading holes and tip left and right to see which way it "leans" to the furthest. If it is directionally drilled, it will not be the same. Double check by verifying the next hole is the opposite.

    Treated the same? Not if figuring out how to lace the rim is a part of lacing.
    Same level of obviousness relevant to the phrase "point out the obvious?" No.
    The difference in obviousness between offset and DD is the point of my post because it is a mistake that many inexperienced wheelbuilders make. Even experienced wheelbuilders can get caught if a company (*cough* Stan's *cough*) changes the way they drill rims.

    I've never done it on these DD carbon rims, but with Velocity rims, which are directionally drilled, it can be seen by lining up the access holes and spoke holes in the rim. When aligned they clearly point to one side or the other.
    Of course, I have a lot of experience shooting compound bows, which may give me an advantage.
    I don't know how the drill rigs are tooled in the case of the carbon rims, but it makes sense for the holes to be aligned on the axis of the drilling direction if they use a single bit to drill both holes, as Velocity does.

    I have built a few wheels ober the years but never seen a rim with a "spoke direction" sticker. I am thinking that it has something to do with the lead spoke orienting to the direction of the CF weave, but I could be wrong

    Can anyone confirm what this refers to?
    Can you please update if these are directionally drilled?

    Hello folks. Sorry for not using search button, but i am looking for answer to a question about chinese carbon rims - are they durable and safe enough? How is the experience overall? Is there any problems that anyone bumped into? Any breaks, crashes?

    One local racer has broken 6 carbon rims, and he says that he was careful enough...
