SHIMANO ULTEGRA RT-CL800 CENTER LOCK DISC ROTOR
HIGH-PERFORMANCE ICE TECHNOLOGIES FREEZA ROTOR WITH LOCKRING
Upgrade your road or gravel braking experience with the Shimano ULTEGRA RT-CL800 Center Lock disc rotor. Built with advanced Ice Technologies Freeza construction and a redesigned rigid spider, it delivers rapid heat dissipation, quiet braking performance, and reliable stopping power even on demanding mountain descents.
FEATURES
- Ice Technologies Freeza: 3-layer sandwich rotor structure (stainless steel/aluminum/stainless steel) with aluminum cooling fins to significantly lower operating temperatures.
- Quieter Braking Performance: Redesigned arm shape reduces heat deformation, minimizing annoying rotor rub and brake noise during long descents.
- Lockring Included: Comes complete with a genuine Shimano Center Lock lockring for quick and secure installation.
- Flexible Size Options: Choose between individual 140 mm or 160 mm rotors, or get a complete 140 mm + 160 mm front/rear combo set.

Q: Does this rotor include the Center Lock lockring?
A: Yes, every RT-CL800 rotor includes a genuine Shimano Center Lock lockring in the package.
Q: What is the difference between RT-CL800 and RT-CL900?
A: Both feature the updated quiet anti-deformation spider design and Ice Tech Freeza structure. The main difference is that RT-CL900 (Dura-Ace grade) features heat-dissipating black cooling paint on the fins for slightly faster heat dissipation, while RT-CL800 (Ultegra grade) has raw aluminum fins.
Q: Can I use RT-CL800 rotors with 105, GRX, or Dura-Ace brakes?
A: Yes! The RT-CL800 uses the standard Center Lock system and is fully compatible with all Shimano hydraulic disc brake systems, including Dura-Ace, Ultegra, 105, and GRX series.
