The new design makes the rotor automatically aligned and makes the brake pads perfect gripping on the rotor which always provides stable braking force.
EFFICIENT TORQUE CONDUCTION:
Special design makes braking power directly and completely transmit to the bicycle, and reduces braking noise
DECREASING HEAT DAMAGE:
The new design offers controlled tolerance preventing structural damage by heat. An aluminum inner frame can make the heat not go into the hub directly to effect safety.
Round Edge:
Safe Design without rotor-cutting risk
Silence Design:
Special Braking surface window, reduces noise from braking
