The Shimano SLX SM-RT66 is a dependable 180mm 6-bolt disc rotor that delivers consistent, controlled stopping power across trail, cross-country and commuting use. Its one-piece stainless steel build resists corrosion and shrugs off the heat of hard, repeated braking.

Highlights

• Consistent, reliable braking performance in all riding conditions
• One-piece stainless steel construction that resists corrosion and warping
• 180mm diameter for stronger braking and better heat capacity than a 160mm rotor
• Compatible with both resin and metal brake pads, so you can run your preferred compound
• Anti-loosen tightening plate keeps the six rotor bolts secure and speeds up installation
• Supplied with rotor fixing bolts and non-turn washers

Built to handle the heat

The single-piece stainless steel rotor body manages braking heat well and stays true under load, giving you a firm, predictable lever feel ride after ride. Stainless construction also stands up to wet Australian conditions without surface rust becoming an issue.

Run your pads, your way

Because the SM-RT66 is approved for both resin and metal (sintered) pads, you can choose quieter resin for dry trails or switch to harder-wearing metal pads when conditions turn wet and gritty, all on the same rotor.

Quick, secure fitment

The included anti-loosen tightening plate locks the six mounting bolts in place so they resist backing out under vibration and repeated braking, making setup faster and giving you peace of mind on the trail.

Compatibility & fit

Standard ISO 6-bolt mount with a 44mm bolt circle, suiting any 6-bolt hub. Compatible with both resin and metal disc brake pads. Designed for Shimano SLX, Deore and other Shimano hydraulic and mechanical disc brake systems, and works with most 6-bolt setups. Confirm your frame, fork and caliper are rated for a 180mm rotor before fitting.
