Shimano Disc Brake Rotor SM-RT81 Deore XT 180mm Centrelock

Or 3 x $13.33 Per Month

Shimano Deore XT is known for its unbelievable performance, technology minded and durable components that can be used day in and day out for a very long time. This is no exemption in these Shimano XT RT-86 Center lock rotors. Shimano made sure that the stopping power is in par with the industry's best and these XT rotors give nothing to the XTR ones in terms of stopping power. The only difference you would be able to find between both would be the slightly anorexic weight of the XTR, reserved for those super hardcore racers that saving 5 grams on a rotor just needs to happen.

When transferring from a "regular" rotor, by regular we mean a single steel piece bolted to your hub, you will notice a considerable difference on long descents where your old rotors would heat up and (actually) boil your brakes, leaving you with 50% or less of the initial braking power. Shimano counter-attack this by ditching the one build material and adding clever solutions to maximize heat dissipation. By using the sandwich method, Shimano employed 2 specially design friction steel pieces with an aluminium core and an aluminium spider. Aluminium is known by it's heat dissipation qualities. The result is a rotor that won't heat up as much as the "regular" ones, won't boil your brakes and will allow you to have all your braking power right in your fingertip even on the longest and steepest of downhills.
