20mm carbon rims low profile and ligh weight,really a high performance for mountain climbing,great lateral stiffess and acceleration.

Our proprietary 255 high Tg carbon can withstand more braking heat and resist brake surface deformation & delamination after

prolonged braking.

Better gluing surface,more reasonable rim bed shape and dimension,ensure carbon tubular rims optimized tire gluing and secure.

New material molded carbon brake surface,optimized brake performance even in variable weather conditions.
