Product Description

SM-RT81 Ice-Tec rotors give excellent performance made from a stainless steel/alloy 3-layer sandwich construction that manages heat while riding. The clad steel/alloy/steel rotor construction allows heat generated from braking to radiate quickly through the aluminium core achieving surface temperature drops of around 50°C. When used with Ice-Tec pads surface temperatures can drop from around 400 to 300°C, this provides great improvements in performance all round.

Review from MBR : August 2012 Rating: 9/10 Construction Shimano's compact XT brake lever and parallel double-barrelled reservoir is derived from the well-regards XTR brake, and comes with an adjustable cam system. This Servo-Wave design pushes more fluid at the start of the stroke (affording the pads more clearance) before smoothing out the force on the rotor when you apply the brakes more firmly. The stubby, hooked-lever assembly comes with a free stroke screw (we ran this fully in) and a tool-free reach adjuster. A hinged clamp allows easy fitment, and an integrated I-Spec clamping option enables perfect integration with Shimano shifters. Oversized 22mm ceramic pistons inside the two-piece XT caliper help prevent heat transfer into the mineral oil, with Ice-Tech finned pads designed to dissipate further heat build-up. There isn't an option to change hose orientation. Performance We've already tried the mega-powerful XT brakes with the metal pads and found them slightly too grabby, so we opted for the resin (F01A) finned pads. With these in place, control and modulation were excellent at low speeds and on sketchy, steep sections in both wet or dry, but still equally capable of scorching to a rapid halt on high-speed fire roads and downhill tracks. The short lever blade fitted our forefinger perfectly. There was no slop and, although it was initially a little reluctant to get moving, the action was then light and smooth, which helped keep our digits relaxed if we rode covering the brakes. Shimano claims its aluminium/steel-layered rotors reduce temperatures by about one-third over a standard all-steel disc and we noticed massively superior performance over Deore rotors. In fact, even a fast 20-minute Lakeland descent didn't make the Ice-Tech rotors flinch. We've already used XT brakes to cover hundreds of wet miles with only one set of new pads, so durability is excellent. Since the brakes aren't the lightest but the power is so great and consistent, we'd have no qualms dropping to a 160mm rotor on the front to save rotating weight. Verdict The latest Shimano XT brakes are hard to fault, with true one-finger operation whatever the conditions. Awesome, manageable power is combined with rotors and pads that keep on performing consistently. Our only small gripe is that running the levers very close to the grip exceeds the optimum leverage position of the cam - a XT lever without the cam, as found on the XTR Race brake, would be a 10/10 for us.
