The SK series front race rotors represent an evolution of the original Braking STX profile rotors, but with precise direction of rotation, meaning the left and right rotors are side specific.
A lower outer braking track designed for today’s radial calipers, lessens weight, reducing unsprung mass, leading to better overall handling and performance of the bike. 40-50g lighter per rotor than the STX series rotors and nearly 1 lb. lighter per set than other brands.
The SK rotors provide FAST reaction and the best lever feel during racing conditions. Precise direction of rotation designed to permit better ventilation capability, maintaining the coolest temperature possible during aggressive use.
