Shimano Dura Ace CL900 Brake Disc Ø140mm CL - Black

With a focus on reducing heat distortion of the disc brake rotor, the result of the new disc brake rotor is quieter than ever, delivering braking performance without compromising on weight or heat dissipation.

- Quieter than ever, with superior, consistent braking performance on long, steep descents thanks to excellent heat dissipation
- The new arm shape is sturdier for quieter operation
- Heat-dissipating coating enhances performance

The Shimano CL900 140 mm disc rotor offers top-class heat management and silent, consistent braking performance during long descents thanks to the Ice-Tech FREEZA sandwich construction and a reinforced aluminum carrier that resists heat distortion. The Center Lock interface with an internal serration lock ring is compatible with quick-release hubs, ensuring precise and secure installation; the large diameter of 140 mm provides maximum braking power for heavier riders, loaded bikes, e-bikes, and mountain biking adventures in all weather conditions.

- The CL900 140 mm rotor delivers powerful and stable braking performance with smooth modulation on long alpine descents
- The Ice-Tech FREEZA stainless steel-aluminum-stainless steel construction quickly dissipates heat to reduce fade and extend brake pad life
- A reinforced carrier and optimized arm shape help prevent heat distortion, keeping the rotor quiet and true
- The Center Lock interface with an external serration lock ring is designed for 12 mm thru-axle hubs, ensuring quick and precise installation
- The 140 mm diameter increases leverage and braking power for e-bikes, bikepacking, and endurance rides in wet conditions
