The Shimano Deore SM-RT64 is a 220mm Center Lock disc rotor built for riders who want strong, dependable braking on long descents and bigger bikes. Its two-piece construction pairs a stainless steel braking track with an aluminium carrier, and the larger 220mm diameter gives you extra stopping power and better heat management when you need it most.

Highlights

• Large 220mm diameter for more braking power and improved heat handling on long, steep descents
• Two-piece design with a stainless steel braking surface and an aluminium carrier
• Center Lock fitment makes installation and removal quick and tool-light
• Works with both resin and metal disc brake pads
• External serration lockring fits all common axle standards, including 12, 15 and 20mm thru-axles and quick release

Built for serious stopping power

Stepping up to a 220mm rotor gives you more leverage at the calliper and a larger surface to shed heat, which means more consistent braking on sustained descents and under heavier loads. The stainless steel braking track stands up to repeated hard stops and wet conditions.

Center Lock convenience

The Center Lock mounting system uses a splined interface and a single lockring instead of six bolts, so fitting and swapping rotors is faster and the connection stays precise and rigid for clean, predictable braking.

Resin or metal pads

The SM-RT64 is compatible with both resin and metal brake pad compounds, so you can tune your setup for quiet everyday riding or extra bite and durability for harder use.

Compatibility & fit

Center Lock hubs only (not for 6-bolt hubs). This is the external serration lockring version, which fits all axle types including quick release and 12, 15 and 20mm thru-axles. Suits Shimano and other Center Lock-compatible disc brake systems running 220mm rotors. Confirm your frame, fork and calliper are rated for a 220mm rotor before fitting, as larger rotors may require a specific mount adapter.
