Shimano XTR Trail Disc Brakes M988


Riding comfortably at speed requires an unconscious, intuitive confidence in your machine. It requires knowing that whatever conditions you come across your brakes will be ready and able to deliver reliable control in any situation.

Say hello to XTR Trail brakes, and say goodbye to compromise. The integration of Servo-Wave brake-boosting technology into an XTR-level brake generates gobs of lightweight stopping power (125 percent of the previous XTR benchmark, to be exact) that can be precisely rolled on and off with single-finger effort leaving a better grip on the bar for charging through the gnar.

With industry-first full ceramic caliper pistons, radiator-fin-backed brake pads to shed performance-sapping heat, these all-new brakes maintain cool, quiet performance under fire.

As the most powerful and most controllable XTR-level brake of all time, XTR Trail absolutely assassinates wide-open descents with uncanny consistency, delivering more confidence than ever before.

The new XTR Trail lever delivers big power. As the first XTR lever equipped with Servo-Wave, riders can precisely control 25 percent more power with highly-adjustable and responsive one-finger braking. When coupled with the XTR Trail lever, the new forged one-piece caliper delivers a balance of light weight and power that resists performance-sapping heat better than ever before thanks to an industry-first full-ceramic piston and optional Ice Technology radiator brake pads.
