Whether you need new or replacement rotors for your Shimano disc brake setup, the XT SM-RT81 Rotor is an excellent choice. Featuring Ice Technology with a stainless steel/aluminum/stainless steel 3-layer sandwich structure, the rotor manages heat better than an all-steel rotor with the same durability when using resin or metal pads. Additionally, it also results in longer pad life and substantially quieter braking. The rotor is then joined to an aluminum carrier which further improves heat dissipation, helps the rotor resist bending, and drops some grams. The result is reduced fade under heavy braking on long descents. These rotors come in 160, 180, and 203mm diameters and are compatible with centerlock hubs only. An HB20 lockring is required for 15 and 20mm thru-axle hubs, which is sold separately.
