Shimano SM-RT66 Disc Rotor - 180mm | 6-Bolt
What is the Shimano SM-RT66 180mm rotor built for?
The Shimano SM-RT66 Disc Rotor 180mm 6-Bolt is built to deliver consistent, dependable stopping power across SLX and Deore level brake setups in all riding conditions. It uses a one-piece stainless steel construction that resists corrosion and holds up to hard, repeated braking, and it ships with Shimano's anti-loosen tightening plate so the rotor bolts stay put and installation is quick and secure. The 180mm diameter steps up braking power and heat capacity over a 160mm, making it a smart front-rotor choice for trail and all-mountain riding.
This rotor mounts to any standard 6-bolt hub on a 44mm bolt circle and works with both resin and metal brake pads, so it drops into most Shimano and cross-compatible disc setups without fuss. It weighs roughly 154 grams and is part of Shimano's proven SLX and Deore family. It is best for trail, cross-country, and commuter riders who want a no-nonsense replacement rotor that just works and lasts.
