Shimano RT-CL800 brake rotors use Ice Technology FREEZA construction to manage heat better during long descents. Their three-layer design and cooling fins help keep your braking consistent and quieter, whether you're on pavement, gravel, or trails. It's a direct replacement for many Shimano brake setups.
Features and Benefits
- Stainless steel and aluminum core - This pulls heat away from the braking surface, which helps reduce brake fade.
- FREEZA heat-dissipating fins - These fins increase the surface area, letting the rotor cool quicker under heavy braking.
- Center Lock mounting system - This gives a stiff, secure connection to the hub, making installation simple.
- Redesigned arm shape - This shape helps cut down on noise, so you get quieter braking on the road or trail.
Applications
- Road bikes - The 140mm size offers lightweight, dependable stopping power for steep mountain passes.
- Gravel riding - The Shimano RT-CL800 works well for gravel bikes that need reliable braking in mixed conditions.
- Mountain bikes - Use the 160mm rotor for extra cooling and braking force on cross-country trails.

Q: What exactly is the 'Ice Technology' in these brake rotors? A: It's a three-layer sandwich construction with an aluminum core between two stainless steel layers. The aluminum helps pull heat away from the braking surface much faster, which reduces brake fade and keeps your stopping power consistent on long descents..

Q: Can I use these on my mountain bike, or are they just for road bikes? A: You can use them on either. They are designed for both road and mountain bike applications, as long as your bike's hub uses the Center Lock standard and your frame has clearance for the rotor size you choose..

Q: What kind of warranty comes with the CL800 rotor? A: Shimano provides a two-year warranty that covers defects in materials and workmanship. This doesn't cover normal wear from use, like the braking surface thinning over time.. Q: What kind of warranty comes with the CL800 rotor?

Q: Why would I choose these over a less expensive, solid steel rotor? A: The main benefit is better heat management. If you do a lot of riding with long, steep descents, these will give you more consistent and reliable braking from top to bottom. For performance-focused riders, that extra control is a significant advantage.. Q: Why would I choose these over a less expensive, solid steel rotor? A: The main benefit is better heat management.
