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.

In 2017 we first tried to use Toray T800 carbon fiber material and to improve the production process, the strength of AM rims increased more than 10% when the weight kept same. In order to maintain the continuous improvement in the performance of AM (All Mountain) carbon mountain rims, we redesigned three models of 29 inch AM-level rims in the year of 2020. The new models are NXT29XM33, NXT29XM36 and NXT29XM41, which can be used for AM and Enduro riding. The inner width is specially designed to 27mm, 30mm and 35mm, which mountain riders mostly prefer. They can be fully adapted to the current popular AM-or Enduro level tires in size 2.0"-2.75". With the premium layer-up system applied, rims get lighter in weight and stronger in performance. The positive stiffness test on all the XM series has reached more than 110J (Flat Hammer, no tire).

Upgrade 2024:

The weight of model NXT29XM36 is only 390g for AM or 420g Enduro. The video of Positive Stiffness Test: VIDEO LINK

The profile drawing of this rim is as below.

The tire size for this model of rim is recommended at 2.0" ~ 2.75". The tire pressure is recommended at 20 ~ 37psi.
