Introduction
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 of UM Series in size 27.5", the NXT27UM32 carbon MTB rim for XC.
The weight of model NXT27UM32 is only 300g. The profile drawing of this rim is as below.
The tire size for this model of rim is recommended at 1.75" ~ 2.25". The tire pressure is recommended at 30 ~ 60 psi.
