Q & A

Shimano have gone back to the drawing board and made significant steps forward with the new XTR hydraulic disc brake system by incorporating a number of their established technologies into a totally re-designed caliper and lever housing, with different specifications designed for either trail or race use; XTR is starting a revolution in mountain bike braking performance.

The main focus during the development of these brakes was to reduce heat buildup, which is the limiting factor in brake performance over extended periods, to this end the M988 forged aluminium caliper uses oversized 22mm ceramic pistons which prevent heat transfer into the fluid and a unique pad setup with aluminium cooling fins built into the backing plates to dissipate heat more effectively. In addition they are designed to be used with Shimano's Ice-Tec rotors which have a sandwich steel / aluminium construction; the end result is that the huge temperatures generated during intense braking (upto 1000°C on the rotor surface) are dissipaited more effectively and quickly resulting in virtually fade free performance even when using smaller rotors.

A new generation of XTR always introduces new designs and the disc brake lever no longer shares any resemblance with the current range, moving from a 90° style housing to one more acutely angled results in a more natural lever position and ergonomic stroke, whilst allows it to sit closer into the bar and for cleaner looks. The housing now features a split clamp to simplify installation and adjustment, whist the new I-Spec system allows for an integrated brake/shifter mounting in the same vein as Avid's Matchmaker clamp. The short 14mm 1.5 finger brake lever provides ample power in all conditions and features a dimpled surface for additional grip in wet weather. The trail version also benefits from free-stroke adjustment, tool-less reach adjustment and Shimano's patented Servo-Wave technology.

The mineral oil brake fluid specified by Shimano is non-corrosive and less hazardous than conventional hydraulic brake fluid, whilst the shim-less mounting system allows for quick installation and set-up. This kit also contains sintered pads, plus spare olives and insert should you wish to adjust the length of the cuttable hoses. Front or rear versions are available, please select from options.

Hose length: Front 1000mm, Rear 1700mm
Note: Kit does not include brake disc rotors and caliper mounting adaptors
