XTR MT900 Ice Tech Freeza Centerlock Rotor

Shimano's XTR MT900 rotor delivers high-performance, consistent, and versatile brake performance in the most demanding conditions. Ice Technologies Freeza construction boosts heat dissipation by a claimed 20% over previous-generation Ice Tech rotors.

Included lockring is compatible with up to 12mm axles and requires a standard FR-5 cassette tool. For 15mm or 20mm axles, you will need the XT M8010 style lockring.
