Shimano RT-CL700 DISC ICE-TECH CENTERLOCK ROTOR - 140mm
Consistent, quiet stopping — engineered for road and gravel, every ride.
The Shimano RT-CL700 is the Ice-Tech Centerlock disc rotor built for 105 and GRX brake systems. An aluminium-core, stainless steel sandwich construction pulls heat away from the braking surface faster than conventional single-layer rotors, so your stopping power stays consistent on long descents and repeated braking situations. The updated 3D-shaped aluminium carrier further reduces rotor noise for a calmer, more controlled feel — no harsh squeal, just smooth deceleration when you need it.
Centerlock compatibility. The RT-CL700 uses Shimano's Centerlock mounting system — secured with a standard lock ring (internal spline) compatible with most Shimano and third-party Centerlock-compatible hubs. Quick to remove, quick to reinstall, zero wobble.
What makes this worth it
Ice-Tech heat management
The aluminium-core, stainless steel sandwich construction dissipates brake heat faster than a standard steel rotor — keeping braking power consistent under sustained load on long descents.
3D aluminium carrier
The shaped carrier is engineered to reduce rotor noise — those harsh metallic sounds that plague cheaper rotors are damped out for a quieter, more confident braking feel.
Centerlock mounting
Shimano's Centerlock interface is faster to service than 6-bolt designs — one lock ring holds the rotor true. The internal spline lock ring is compatible with most Shimano and third-party Centerlock hubs.
105 & GRX compatibility
Spec'd to pair with Shimano 105 R7100 and GRX 800-series brakes — the same Ice-Tech rotor standard across Shimano's road and gravel brake lineup.
Two size options
Available in 140mm (lighter, faster-clearing) and 160mm (more power, better for heavier riders or loaded gravel). Choose by frame clearance and your typical terrain.
Shimano rotor hierarchy
The RT-CL700 shares Ice-Tech DNA with the Ultegra CL800 and Dura-Ace CL900 — same core technology, optimised for the 105/GRX tier. A genuine upgrade over third-party alternatives.
