Shimano XTR M987 Disc Brake Caliper

Shimano have redesigned their XTR XC race brake – now known as the M987. Significant weight savings have been introduced, along with a new rotor design offering improved heat dissipation.

The additional weight of many 29ers was a key consideration during the design process. Weight savings are claimed to be 40g per brake compared to the previous XTR Race M985, achieved by using a magnesium lever and caliper body along with carbon lever blades and titanium hardware. The range-topping M987 is actually Shimano's lightest hydraulic disc to date. The BR-M987 caliper is also compatible with Shimano's Ice Tech finned brake pads.


  • Shimano XTR cutting edge braking technology, lightweight and powerful easily adaptable post-style hydraulic disc brake calliper
  • Oversized 22mm ceramic pistons optimized for heat insulation, lightweight and stiffness
  • Opposed 2-piston design reduces leading effect and optimal pad wear increases braking control
  • Super lightweight magnesium calliper design with Titanium hardware
  • Can be used with a choice of adapters and rotors giving you the freedom to customise and suit your bike
  • Recommended for use with Ice Tech Centre-Lock rotors for optimum braking performance in a choice of 160 mm, 180 mm and 203 mm
  • Can be used with Ice Tech pads available in resin or sintered compound, the optional aluminium radiation fin pad further improves heat dissipation reducing brake surface temperature by 50 deg C
  • Easy to use one way oil bleeding for improved oil routing
  • Mineral oil brake fluid
  • Shim-less mounting system
  • Banjo style attachment for neat hose alignment
  • Contains standard G01A resin pads, plus optional bleed nipple blanking grub screw to save a further 3 grams
