The Shimano Deore XT RT-CL800 disc brake rotor eliminates the dreaded ticking, rubbing, and howling that plagues traditional rotors after heavy braking. By engineering a wildly robust new alloy carrier and an optimized arm shape, Shimano has drastically reduced heat-induced deformation, meaning this rotor stays perfectly true and silent even when subjected to extreme temperatures.
Built on the legendary ICE TECHNOLOGIES FREEZA architecture, it sandwiches a highly conductive aluminum core between stainless steel braking tracks to rapidly bleed off heat. The result is absolute, fade-free stopping authority and whisper-quiet performance on the most punishing descents, all without sacrificing your weight-weenie build goals.
Crucially, these new rotors are recommended for both road and mountain bike braking systems. Blurring the lines between disciplines, they are available in sizes scaling up to a massive 203mm to handle high-torque gravity applications, and are the ultimate upgrade for consistent, noise-free braking, whether you're navigating steep gravel chutes, flat-out tarmac, or aggressive singletrack.
________
Specifications:
- Quieter than ever, but with superb, consistent braking performance on any long, steep descents thanks to excellent heat dissipation
- The new arm shape is more robust, leading to quieter operation
- Optimized 3D-shaped aluminum carrier is designed purposefully in every single dimension and achieves lightweight and superb heat distortion resistance.
This prevents the entire rotor from deforming due to heat and reduces rubbing noise while riding. -
