About this rim
The details
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 2023, when designing and developing the Supreme Edition Alpha 30 rim (now Premium Edition), we tried to use different modulus carbon fiber materials and to apply a new stacking manufacturing technology. It brings an ultralight weight XC mountain bike rim, which weight is only 255g. Comparing to the other premium edition rim like NXT29UM30 which is 310g, the Alpha 30 rim is so lighter. Here we do not make detailed public introductions to the materials and the stacking manufacturing techniques.
In the impact test without a tire mounted, the strength of the Alpha 30 reached 70J, which has already passed the test standard of the Premium Edition XC mountain rim. The specific impact test video can be watched here TEST VIDEO
This rim could be used for XC (Cross Country), Marathon and Trail riding. The tire size for this model of rim is recommended at 1.75" ~ 2.15". The tire pressure is recommended at 22 ~ 40 psi.
