For XC (Cross Country) mountain bikes, if you want mtb carbon wheels which are easy for maintenance and do not care a bit heavier weight, 4-spoke carbon wheel is good option.

Since 4-spoke carbon wheel is made in one-piece, there is no traditional spoke needed, which makes it easy for maintenance (no need true spokes or replace spokes).

ProX 650b 4-spoke MTB carbon wheel is designed for 650b mountain bikes (or other bikes that fit 27.5’’ wheel).

If you want wheel for 29er mountain bikes, please check another page of our 6-spoke carbon mtb wheels.

The rim side wall in our carbon spoke wheel is thicker than regular carbon rims, which is of better stiffness and strength.

In our MTB 4-spoke carbon wheels, Chosen hubs (made in Taiwan) are used, with Shimano 11s HG, 12s MicroSpline, Sram 11/12s XD freehub optional.

The default hubs come with boost standard (front 15*110, rear 12*148mm). Non-boost (front 15*100, rear 12*142) can also be ordered (need to emphasize it when contacting us).
