  • Manufacturing process
    Our air bladders are made from a special material which produces smoother walls, result in a lighter rim, and are completely removed without harsh chemicals. They are removed through the valve hole with a unique process so that the rim does not have to be patched like traditional manufacturers use. This significantly improves the strength of the rims. Read More about our process
  • Precise layup
    Each rim carries its own layup schedule documents which are followed meticulously by the layup workers. Our Engineering team creates a unique fiber orientation which amplifies the desired riding characteristics for a given rim.
  • Angled Holes
    Angled spoke holes allows the nipple to pull straight in line with the spoke for reduced stress. This results in fewer broken spokes and nipples.
  • U-Shape
    U-shape profile spreads the force of impacts and creates a more robust product.
  • Bead lock
    The small ridges on either side of the drop channel help secure tubeless tires in place. The bead lock makes it easier to seal up tubeless tires with a floor pump, and they are incredibly hard to burp.
  • Tubeless
    While the rims are optimized for a tubeless setup with the addition of tubeless tape, they also work with tubes.
  • Asymmetrical
    The profile allows for equalized spoke tension which creates a stronger wheel that stays true.
  • Hookless
    Carbon fiber flows continuously over the bead area to provide the best impact resistance and a significant strength increase compared to a clincher rim.
  • T700
    Constructed with premium Toray T700 carbon fiber. The best strength to weight ratio with no expense spared.

Hi Is this the same rim with modelname RM29C21?
LightBicycle : (2018-01-19)
Hello Anders, Thanks for your contact. The AM928 is the same as RM29C21. The new name AM928 is based on the rim inner width. Do you like to order the same RM29C21 rims or is there anything we can do for you? Thanks, Lightbicycle

Hello, can you tell me by how much the spoke holes are offset from the centreline of the wheel? Thanks :-)

Hello Ben, Thanks for your continued support. The AM928 asymmetrical rim is offset by 2.6mm. Rim profile attached for your reference. Thanks, Lightbicycle

I'm interested in the AM928 as well as the RM29C14 rims for my MTB, I like the AM928s but can't figure out why they are so much more expensive. Is there something I should know that justify the exter $84 per rim?
LightBicycle : (2017-06-02)
Hello Charlie, Thanks for your inquiry. Please find the difference between RM29C14 and AM928 rims as below. -Both rims feature angled spoke holes, a modern u-shaped profile, have a bead lock and work with or without tubes. Both rims also have a low profile hookless bead with a large radius which helps reduce pinch flats. -Our 34mm asymmetrical rims will have more even spoke tension than our 38mm which results in a more durable wheel build. The low tension spokes will be at higher tension compared to a traditional rim which results in less wheel re-truing. -The 38mm are wider and deeper so the lateral and vertical stiffness are increased. Riders that prefer a more compliant ride would be happier on the 34mm rims. The 34mm rims with their new layup design have the best strength to weight ration in our lineup. -And it is 2 years warranty for asymmetrical rims/wheels. It is only 1-year warranty for symmetrical rims/wheels. Thanks, Lightbicycle

Hi I damaged the rim on my sram roam 50 front wheel. I stead of buying a new front wheel I am considering rebuilding my wheels with carbon rims. the spoke count is 24 on the front and the back. Will the rims hold up to that? my wight is 90kg and i ride agressive xc on a hardtail. best regards Lasse
LightBicycle : (2017-05-09)
ello Lasse, Thanks for your inquiry. Normally, more spokes give the rim greater strength and rigidity. Most of our customers choose 28H or 32H rims which make wheels stronger. If you take XC riding only and go with AM928, it is okay to order the 24H rims also. Thanks, Lightbicycle

Hi, I am looking for another set of your rims. Should I just use the asymmetric rim for my rear wheel and a standard non asymmetric rim for the front? eg EN928 for rear All Mountain RM29C07 Just trying to keep the cost down and the non asymmetric rims are cheaper. Thanks
LightBicycle : (2017-03-24)
Hello Justin, Thanks for your inquiry. It will be great if you get both front and rear with asymmetric rims. You will get more even spoke tension with the asymmetrical rim which makes for a more durable wheel build. For symmetric rim, the spoke tension is different on both drive and non-drive side. However, if you are on a budget, let’s go with front RM29C07/ rear EN928. Thanks, Lightbicycle

Is the cost quoted above per rim or set of two?
LightBicycle : (2017-03-22)
Hello again, Our price is for one single rim. Thanks, Lightbicycle

Hello- I have some Industry 9 Hubs and Spokes, could I fit those to the AM928 32H? Thanks
LightBicycle : (2017-03-22)
Hello Mike, Thanks for your inquiry. Our AM928 rims will work with Industry 9 hubs. For spokes, may I know your rim ERD? Then we will check if you can reuse your spokes. Normally, you need to get some new spokes, because the rim ERD is different, so the spoke length will be different. Thanks, Lightbicycle

I am looking for 2 each AM928 at 415 grams/each. Do you have any in stock? How long will it take for shipment, costs for duty tax to California? Do you sell DT Swiss 240 boost hubs for front and rear? Thank you.
LightBicycle : (2016-12-06)
Hello Rean, Thanks for your inquiry. Below are the lightest AM928 rims we stocked for your reference. We cannot manufacture the rims at 415g. It is too light and not strong enough for all mountain riding. If you like lighter rims, you can go for RM29C19 rims. What do you think? Thanks, Lightbicycle

Hi, Other than the dimensions, could you tell me the difference between these rims and the RM29C14 please? I see these are $85 more per rim. Thanks
Light-Bicycle : (2016-09-18)
Hello Mark, Sorry for the late reply. Because we were on vacation in last 3 days. Our asymmetric line of rims is inventoried so we can ship quickly. Yes it is more expensive (inventory and our product improvements cost more), but it does offer a higher level of service. The crash replacement coverage is increased and time period is doubled. With the addition of increased performance and durability etc. this could be a viable option for customers wanting something at this level. The hookless "lips" on the 38mm rim are 3.2mm wide vs. 3mm on the asymmetrical rim. Both are the same depth and are quite strong. Technically the 38mm yields a slightly higher impact resistance, but it's quite close. You will get more even spoke tension with the asymmetrical rim which makes for a more durable wheel build, so the 34mm has the advantage there. If you prefer a slightly more round and more natural tire profile with medium stiffness, go with the asymmetrical rims. If you prefer a wider more squared off profile with more volume, then go with the 38's. Thanks, Light-bicycle
