TRP Centerlock-25 Rotor TRP's Centerlock-25 Rotor is a little more advanced than a standard rotor. The two-piece rotor offers superior heat dissipation due to an aluminum center and excellent stiffness to provide you with the most confident braking possible. TRP's design with six recessed slots creates channels for dirt and debris to fall through. If you want to increase your stopping power and experience better heat dissipation, upgrade to a larger rotor.
