For use with 2000+ Hayes 74mm eye-to-eye calipers (adapters/calipers for 22mm mounts are no longer available) - (IS) International Standard 51mm tabs; (QR) Quick Release; (TA) thru-axle - Note: Fox-36/40 (thru-axle), Rock Shox Pike (Maxle), and Psylo (Tullio) axle forks use IS-QR adapters

The D-Series rotor was developed in conjunction with the new Dominion disc brake, designed to provide consistent and reliable stopping power under all conditions. - Proprietary friction surface, optimized for use with Hayes T106 (Semi-Met) or T100 (Sintered) pads to deliver fast, consistent burnish, predictable friction rate, and consistency across temperature and speed conditions - MRC (Modal Resonance Cancellation): Tuned to cancel resonance and vibration, particularly when paired with Hayes T106 (Semi-Met) and T100 (Sintered) pads - 1.95mm thickness enhances heat dissipation - Includes mounting hardware

- Prime 2-piece rotors are for Prime Pro and Expert brakes only - L-series, lightweight one piece rotors - V-cut profile steel rotors for optimum weight-to-performance ratio. Increased surface area over previous designs increases power while cutouts and drillings help keep pads clean - Rotors includes: (1) 6-bolt/44mmBCD rotor, (1) Torx wrench, and (6) T-25 rotor mounting bolts with thread retaining compound - 205g @ 203mm
