SM-RT66MP 6-Bolt Disc Brake Rotor - 180mm

Shimano SM-RT66MP SLX 6-bolt disc brake rotor in 180mm is a dependable choice for riders who want consistent braking feel across changing trail and weather conditions. The 6-bolt mount keeps compatibility broad across MTB hubs, while anti-loosen plates help keep rotor bolts secure for confidence on long descents and rough terrain.

• 180mm rotor size - adds leverage for stronger, more controlled braking compared to smaller rotors (frame/fork clearance permitting)
• 6-bolt mounting interface - widely compatible with standard 6-bolt hubs for straightforward swaps and service
• Anti-loosen plate construction - helps prevent rotor bolt back-out to reduce mid-ride checks and re-torquing
• Resin or metal pad compatible - supports a wide range of pad choices to match noise, bite, and durability preferences
• Hardware included - comes with rotor fixing bolts and non-turn washers for a complete install
