The Shimano Deore SM-RT54 is a dependable 180mm Center Lock disc rotor that delivers consistent, controlled stopping power for trail and everyday riding. The larger 180mm diameter adds braking leverage where you need it most, and the Center Lock interface makes fitting and swapping quick.

Highlights

• Larger 180mm diameter for stronger, more confident braking
• Center Lock mounting for fast, tool-light installation and removal
• Internal spline lockring to suit Center Lock hubs that use the internal lockring standard
• Tuned specifically for resin (organic) brake pads for quiet, progressive feel
• Two-piece construction for reliable, consistent performance

Center Lock convenience

The Center Lock spline mount and lockring replace the six bolts of a traditional rotor, so installation and removal are quicker and the rotor seats precisely on the hub for added rigidity and braking accuracy.

Built for resin pads

This rotor is designed for use with resin (organic) brake pads only. Resin pads bed in quickly and offer a quiet, progressive bite, making this a sensible match for general trail, commuting and recreational riding. It is not rated for metal (sintered) pads.

Compatibility & fit

Suits Center Lock hubs only. This is the internal spline lockring version (SM-RT54-MI), which fits Center Lock hubs that take an internal-serration lockring; if your hub uses an external lockring you need the SM-RT54-ME variant instead. The 180mm size requires the matching brake calliper mount or adapter for a 180mm rotor. For use with resin (organic) pads only.
