Description

XT RT81 Centerlock Disc Rotor

Shimano's XT-level centerlock rotor uses Ice Technology and a deeper disc area to manage heat better than an all-steel rotor. Ice-Tech construction consists of an aluminum core sandwiched between steel exteriors to provide better heat dissipation. The rotor is then joined to an aluminum carrier which further improves heat dissipation and also helps the rotor resist bending. The result is reduced brake fade for more consistent braking, especially on long descents. These rotors are compatible with centerlock hubs only. An HB20 lockring is required for 15 and 20mm thru-axle hubs, which is sold separately.

  • Ice-Tech design manages heat for consistent braking on long descents

Works great

  • Familiarity: I've put it through the wringer

Shimano rotors are made well and paired with the correct Shimano brakes, makes stopping a breeze.

Unanswered Question

Will these rotors fit in Sram Level TL brakes? (using same rotor size as the Sram rotors.)
