  • [Premium] 29" Asymmetric Mountain Carbon Rim 35mm


The carbon fiber bicycle industry has been innovating and advancing all the time. Being lighter and stronger has always been the pursuit of the professional bicycle industry, especially for the mountain rims for XC (Cross Country) riding , where riders have extreme weight requirement.

In the year of 2017, we first tried to use Toray T800 carbon fiber material and to improve the production process, reducing a weight of 60g for the XC mountain rim, which is a huge improvement. In the year of 2022, we upgraded the rim of NXT29XMA35 with new layer-up system, the weight decreases 20g than the previous generation when the strength kept same. 

The weight of model NXT29XMA35 is only 325g. The profile drawing of this rim is as below.
