A good fit for anyone servicing a compatible commuter, recreational, road or mountain bike fitted with a CENTER LOCK hub and resin brake pads.
The Shimano SM-RT30 is a 180 mm CENTER LOCK disc brake rotor designed specifically for resin brake pads. It suits riders replacing a worn rotor or refreshing a compatible braking system without changing to a different mounting standard or pad compound.
CENTER LOCK uses a spline mount and lock ring rather than six separate bolts, helping make rotor installation and removal quicker and more straightforward. The secure spline fixing also supports precise, rigid rotor mounting for consistent braking operation.
This rotor uses a two-piece stainless-steel construction and is supplied with a lock ring featuring internal and external serration for easier installation. Choose the SM-RT30 when you want a practical, easy-to-service rotor for a compatible bike; check that your hub is CENTER LOCK and that your callipers use resin pads before ordering.
