Shimano XTR M9100 - Back to where it all started.

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.

J-Kit (Easy Hose Joint System)

At brake systems with J-Kit hose joint the brake lever features an integrated olive what makes an easy brake hose installation and removal possible.

Shimano XTR BL-M9120 brake lever

The Shimano engineers have redesigned the XTR 9100 brake levers from a braking system that had been already the benchmark among mountainbike braking systems. For the BL-M9120 levers both the clamp and the lever body itself have been modified. The clamp moves further into the middle of the lever and is angled. This cleverly supports the outer end of the expansion tank directly on the handlebars and creates an additional counter bearing for lever actuation.

This significantly increases stiffness and stability, what ultimately leads to an even more direct brake feeling and improved control. So the BL-M9120 is 8 % stiffer than its predecessor, too. The Enduro brake lever is especially developed for use with the BR-M9120 4-piston caliper and features a tool-free reach adjustment as well as an additional adjustment option for the free travel. Servo Wave technology guarantees smooth and predictable control with the right balance of power and rigidity. Thanks to the I-Spec EV design the XTR SL-M9120 shifting levers can be mounted directly to the brake lever.

Shimano XTR BR-M9120 disc brake caliper

The Shimano XTR BR-M9120 brake caliper has a one-piece aluminium construction and ensures significantly faster response and less free travel of the entire 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.
