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 M987 forged magnesium caliper uses an opposed 2 piston design (with oversized 22mm ceramic pistons which prevent heat transfer into the fluid) to provide excellent modulation, reduce leading effect and extend pad longevity. In addition they are designed to be used with Shimano's Ice-Tec rotors which have a sandwich steel / aluminium construction to help dissipate the high temperatures generated when using smaller cross country rotors in a race situation, preventing brake fade lap after lap.

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, whilst the new I-Spec-B system allows for an integrated brake/shifter mounting in the same vein as Avid's Matchmaker clamp. The super-short 13mm 1 finger brake lever provides ample power in race conditions and features a dimpled surface for additional grip in wet weather. The lightweight race version features Shimano's patented Servo-Wave technology but forgoes tool-free reach and free-stroke adjustment in order to save weight

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
