1. Proprietary 255TG resin system carbon fiber can withstand high heat from braking,tested in Taiwan Braking Lab without compromise,resist clincher carbon rims brake track deformation and delamination confidently

2. Auto-machine process can remove extra resin on brake surface,allow brake pads to work on carbon fiber directly,creates better braking performance in dry and wet condition.

3. Extra weight compensation on the rim valve hole opposite,reach the completed wheels dynamic balance.

4. Water drain holes on each size of the rim,opposite to valve,will dry out rim's cavity after wet ride or bike washing.
