The Shimano RT-CL700 is a high-grade Centre Lock disc rotor that brings Shimano's proven Ice-Tech cooling down from the top-tier rotors, so your brakes stay powerful and consistent ride after ride. At 180mm it gives you extra stopping power for heavier loads, longer descents and bigger riders, with quiet, fade-resistant performance in all conditions.

Highlights

• Ice-Tech three-layer construction sheds heat fast for consistent power and less brake fade
• 180mm diameter delivers strong, controlled stopping for descents and heavier setups
• 3D-shaped aluminium carrier resists heat distortion and helps keep braking quiet
• Centre Lock fitment makes installation and removal quick and secure
• External serration lock ring included in the box
• Suits road, gravel and hybrid disc-brake setups

Ice-Tech cooling that holds up

The braking surface is a sandwich of stainless steel, aluminium and stainless steel. The aluminium core pulls heat out of the braking track far faster than a solid steel rotor, which keeps power consistent on long or repeated braking and fights the warping that causes pulsing and rub.

Quiet, stiff and easy to fit

An updated 3D-shaped aluminium carrier adds stiffness and resists heat distortion, so the rotor stays true and runs quietly. The Centre Lock spline mount and lock ring let you fit or swap the rotor in seconds with a single tool, with a precise, rigid interface that improves braking feel.

Compatibility & fit

180mm Centre Lock rotor for hub-mounted Centre Lock disc hubs. This is the external serration version and uses an external lock ring (included). It pairs with Shimano road and gravel disc systems such as 105 and GRX, and with any Centre Lock hub and Shimano-compatible disc calliper rated for a 180mm rotor. Confirm your hub is Centre Lock (not 6-bolt) and that your frame, fork and calliper mounts are set up for 180mm before fitting.
