TRP-33 TRPs two-piece rotors offer superior heat dissipation due to the aluminium centre, as well as excellent stiffness, providing you with confidence in your braking and lighter weight in 180/203mm sizes. Two-piece is now combined with TRPs new slotted rotor is design. Six recessed slots create channels to allow water, mud, and other debris trapped between the pad and rotor to escape under braking. When debris gets trapped between the pad and rotor braking power is dramatically reduced, these recessed slots maintain a more consistent brake feeling in mixed conditions. 2 Piece Slotted: Sizes: 140mm, 160mm, 180mm, and 203mm. Six slots to remove water, mud, and debris. Two-piece design for heat management and stiffness. Spyre Disc Rotor: TRPs latest disc brake rotor designed specifically for use with the TRP Spyre, Spyre SLC, Spyke, Hylex and HyRd. Offers smooth braking and excellent heat dissipation. 29 - Slotted Stainless: TRPs slotted rotor is designed for the most demanding riders in the most demanding conditions. Six recessed slots create channels to allow water, mud, and other debris trapped between the pad and rotor to escape during braking. When debris gets trapped between the pad and rotor braking power is dramatically reduced, these recessed slots maintain a more consistent brake feeling in mixed conditions. Upgrade the stopping power and heat dissipation by increasing the size of your rotor giving you more surface area and leverage. 2 Piece Disc Rotor: Sizes: 140mm, 160mm, 180mm, and 203mm Superior heat dissipation and excellent stiffness. Includes T25 Torx wrench and mounting bolts. Centrelock Disc Rotor: TRPs two piece rotors offer superior heat dissipation due to the aluminium centre as well as excellent stiffness to provide you with confidence in your braking. Upgrade the stopping power and heat dissipation by increasing the size of your rotor giving you more surface area and leverage. ¢ Sizes: 140mm, 160mm and 180mm. ¢ Compatible with Centrelock hubs. ¢ Does not include lock-ring.
