For BMX carbon rims, strength should come first. 

ProX provides two sizes of 20 inch BMX carbon rims, ETRTO 406mm and 451mm. They can be used for BMX bikes as well as folding bikes.

Both models are made from high strength Toray T700 carbon fiber +  stable resin system, which is the basis to guarantee strength.

In addition, we optimize the lay-up design, make our BMX carbon rims much thicker than road rims, to make sure they are strong enough for jumping.

We do strict impact testing for our carbon BMX rims, make sure they are able to tolerate great force coming from jumping and keep riders safe.
