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 27.5 inch AM-level rims in the year of 2020. The new models are NXT27XM33, NXT27XM36 and NXT27XM41, 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 1.75"-2.4". 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, the Enduro version even reached more than 120J.

The weight of model NXT27XM33 is only 350g for AM and 380g for Enduro. The profile drawing of this rim is as below.

The tire size for this model of rim is recommended at 1.75" ~ 2.4". The tire pressure is recommended at 22 ~ 42psi.
