absoluteBLACK Premium Oval Road 38T Shimano 9100/8000 - Blk HS&LS compression In contrast to floating discs

In contrast to floating discs the torque is transmitted to the dovetail-shaped toothing over its entire surface instead of just the rivets increasing the rigidity of the brake disc and the degree of heat dissipation under continuous load

Chain: SRAM XO Eagle Transmission

This allows riders to go faster at the same power output and through corners with confidence
