The Shimano XTR M9100 group was developed to meet the demands of mountainbike racers at the highest level and guarantees "second to none" performance.

The range offers the most versatile components for XC, Enduro and Marathon races.

It all started with the search for the ultimate MTB racing components and now the XTR continues 27 years of innovation with even more speed, focus and control. It is jam-packed with the technological advantages needed to push the boundaries of today's insanely demanding courses. It is lighter, smoother, more durable and versatile to transfer all pedal-pounding watts into ground speed with extreme efficiency.

The Shimano XTR BR-M9120 Postmount brake caliper has a one-piece aluminium construction and ensures significantly faster response and less free travel of the entire XTR 9100 brake system when combined with the highly rigid braking cables. In combination with the especially developed BL-M9120 brake lever the 4-piston caliper makes use of its immense potential. So the BR-M9120 offers 10 % more braking force than its predecessor. The N03A Resin or N04A Metal brake pads with cooling fins in combination with the 4-piston caliper guarantee extremely good deceleration and low weight at the same time.

Please pay attention to the maximum permitted disc diameter depending on your fork or frame.
