TRP Centrelock RotorWith its two-piece construction that consists of an aluminium central spider and a drilled steel braking surface, this centrelock type rotor from TRP gets the best out of your road bike’s or mountain bike’s (MTB’s) disc brakes. The aluminium centre draws heat built-up away to prevent the dreaded “brake fade” on long descents and it stiffens up the rotor too, for consistent operation as you’re riding at your limit. That’s not all, as TRP has added recessed slots that enable dirt or water build-up to escape quickly, so you can rely on your brakes in all riding conditions.Features:Mount Type: CentrelockBrake Compatibility: Road and Mountain Bike (MTB) brakesThickness: 1.8mmExcellent heat dissipationAluminium spider body channels heat away quicklySix recessed slots allow water, mud, and other debris to escape easilyLock ring not includedManufacturer’s Part Number: TRP-25Buy TRP Components from Chain Reaction Cycles, the World’s Largest Online Bike Store.
