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 requirements.

In 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 rims, which is a huge improvement. In order to further meet the market's more performance needs and size preferences for light weight mountain rim, we redesigned the shape of ultralight mountain rims from the year 2020 to 2021. Here comes with the mountain bike rim UM Series, including the NXT29UM27, NXT29UM30, NXT29UM32 and NXT29UM35 rims. 

The weight of model NXT29UM32 is only 320g. The profile drawing of this rim is as below.
