One 10 yard roll of tape will be included.

On mountain bike rims, one layer of 18mm width tape is strong enough to seal the access holes which makes for the lightest tubeless setup.

The 38mm rims are very popular amongst riders looking for a strong and wide carbon rim. The 31.6mm internal width works well with high volume tires and the wide bead seat helps to prevent tire burping on tubeless setups. These imposing rims have a 32mm depth so you will get a very responsive wheel that can hold it’s line through rough terrain.


For really aggressive riders or those using the bike park from time to time, we have an HD version. The HD version receives an extra wrap of 3k carbon fiber for additional wall thickness and reinforcement so they can handle G-outs better than the normal version.

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.


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


T700: Constructed with premium Toray T700 carbon fiber. The best strength to weight ratio with no expense spared.


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.


Pro Series: from date of purchase, 3 years warranty
Non-Pro Series: from date of purchase, 15 months warranty

Crash Replacement: from date of purchase, 30 months with 10%+ discount subject to rim model

Hi, Are these rims the only am/dh rims that you can manufacture in UST (without spoke holes on rim bed)? And could you build a wheelset with them as UST?


LightBicycle 2018/06/06

Hi Adam, We can customize made any rim as UST and build wheels with it. Note that his custom service does not require extra charge from you. The UST wheelset is without spoke access holes on rim bed. Please find attached pictures 650B UST wheelset for your reference. Thanks, Lightbicycle

Hello, Is there a chance you would know the diameter of the holes on the rim? The ones that are covered by tubeless tape. I've got this set of rims on the way and I'd like buy VeloPlugs for them but I don't know if the holes are 8 mm or 8,5+ mm in diameter (and can't measure yet). Regards, Sasa


LightBicycle 2018/03/12

Hi Sasa, The spoke access holes on rim bed is 8mm. Thanks, Lightbicycle

Garofalo 2017/06/04

Hi! I'm thinking about building my next LightBicycle wheelset for my downhill bike. So far i am very satisfied with the light cross country rims i bought from you. I'm wondering if this rim is your most suitable offer for a downhill bike. I use to ride quite hard on technical downhills in europe and in the alps. They will have to withstand big jumps and drops as well.. Would they be a good choice?


LightBicycle 2017/06/05

Hello Garofalo, Thanks for your continued support. According to your info, our 38mm wide 650B HD rim is strong enough for your riding. The HD version has extra layers for increased stiffness and sidewall reinforcement. Ideal for large and aggressive riders. Thanks, Lightbicycle

Chris 2017/02/13

What is the main advantages and disadvantages between these and the en/am733 besides the dimensions?


LightBicycle 2017/02/14

Hello Chris, Please find below rims difference between RM650BC13 and AM/EN733. -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 40mm 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 40mm has slightly increased impact protection than the 38mm but both are quite strong, especially in the heavier/reinforced version of the rim. The 40mm are wider and deeper so the lateral and vertical stiffness are increased. -Both rims come with a 1-year warranty. The 40mm rims have a 2-year crash replacement policy at 25% discount, and the 38mm have a 1-year crash replacement policy at 15% discount. Thanks, Lightbicycle
