Shimano XTR BL-M9220 / BR-M9220 Disc Brake Set - Post Mount | 4-Piston

The no-compromise Di2 system delivers Shimano’s ultra-precise and lightning-quick electronic shifting capabilities, with increased durability across each component. Engineered to withstand the demands of real-world racing, the new group features Shimano’s most robust drivetrain construction to-date, more intuitive ergonomics, predictable braking control, and new customization features that every rider can appreciate.

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.

Shimano XTR BR-M9220 disc brake

One of the most significant changes for XTR comes with an updated braking system that delivers Shimano’s most powerful and most predictable braking control ever.

Improving upon the Shimano’s lightest post-mount offering, the BR-M9200 two-piston post-mount caliper is equally at home on the World Cup cross country circuit when paired with BL-M9200 lever, or on rougher, steeper trails with the BL-M9220 Enduro/trail lever. Heat-resistant resin pistons, resin and metal pad options, and new low viscosity mineral oil make the M9200 caliper the ideal option for any two-piston brake requirement.
