SHIMANO SM-RT66 6-BOLT DISC BRAKE ROTOR
HEAT-TREATED STAINLESS STEEL — RESIN & METAL PAD COMPATIBLE
Upgrade your braking reliability with the genuine Shimano SM-RT66 6-Bolt Disc Brake Rotor. Available in 160mm and 180mm sizes, this rotor is crafted from precision heat-treated stainless steel to ensure consistent stopping power and smooth modulation. Unlike entry-level rotors, the SM-RT66 is fully compatible with both resin (organic) and metallic (sintered) brake pads, making it a versatile choice for MTB, Gravel, and Commuter builds. This OEM package includes the rotor, 6 T25 mounting bolts, and 3 anti-loosen tightening plate washers.
FEATURES
  • All-Pad Material Compatibility: The hardened stainless steel surface is rated for both resin and metallic (sintered) brake pads, offering versatility for all weather conditions and riding styles.
  • Heat-Treated Stainless Steel: Provides superior heat management and durability compared to standard steel rotors, reducing brake fade on long descents.
  • Mud-Shedding Design: Precision-cut venting slots rapidly clear water, mud, and trail debris, reducing pad wear and preventing brake squeal during wet rides.
  • Complete Hardware Kit: Includes 6x T25 Stainless Steel Bolts and 3x Dual-Hole Tightening Plate Washers designed to lock bolts in place and prevent loosening under vibration.
  • 6-Bolt Mount Standard: Compatible with all standard 6-bolt disc brake hubs (IS Mount).
