Shimano Deore XT SM-RT86-M2 Disc Brake Rotor - 180mm, 6-Bolt, Silver/Black

A 180mm 6-bolt Ice Tech disc brake rotor for XT-tier mountain bike builds, the Shimano Deore XT SM-RT86 Disc Brake Rotor (180mm) uses Shimano's Ice Tech 3-layer clad construction (stainless steel, aluminum, stainless steel) to pull heat out of the braking surface, which reduces fade on long sustained descents. The two-piece rotor pairs an aluminum spider with stainless braking surfaces and includes an anti-loosen tightening plate, with the 180mm size weighing approximately 149-154g. Compatible with both metal and resin pads. The SM-RT86 is the right 6-bolt rotor for XT-tier MTB builds where rotor heat management matters and the hub uses the 6-bolt interface rather than center-lock.
