What Our Gearhead® Experts Are Saying: "I recommend this rotor for riders dealing with variable conditions. The two-piece construction manages heat well on long descents, and the slotted design noticeably improves consistency when things get wet or muddy. It delivers solid braking feel without excess weight." When conditions are unpredictable and braking consistency matters most, we turn to the Tr33 Disc Rotor to keep control dialed. Designed by TRP to perform in mixed environments, this rotor blends efficient heat management with dependable stopping power for road, gravel, and trail riding. The two-piece construction pairs a lightweight aluminum center with a steel braking surface to improve heat dissipation and maintain stiffness under load. Six recessed slots create channels that evacuate water, mud, and debris from the braking surface, helping maintain a more consistent lever feel when conditions deteriorate. Whether we’re dropping into long descents or riding through wet terrain, this rotor delivers reliable braking performance we can trust.
