XTR BL-M9120 Disc Brake

If you follow mountain bike news, then you already know well about Shimano's leap into the future with its new 12-speed groupset, and with the beefier cassette and gear range, there's no doubt that you'll want a shiny new brakeset to go along with your setup. In years past we knew Shimano's XTR brakes by their "Trail" and "Race" designations which have been done away with this year, and to keep things simple, we'll say that the new XTR BL-M9120 follows the line of evolution from the 9020 Trail brake from before, but with some major improvements, like quicker brake engagement with shorter free stroke, and increased stiffness over the 9000 series, even under high temperatures.

The XTR BL-M9120 is stocked with all of the bells and whistles we want for enduro riding and multi-day peak-to-peak epics, like Servo Wave for lever adjustability, an updated brake lever shape that's more comfortable for 2-finger braking. It's compatible with Shimano's newest I-Spec, the I-Spec EV shifting lever mount, for a clean and organized cockpit. With I-Spec EV you'll find that the clamp location moves inward from the previous design, while the new master cylinder contacts the handlebar, elevating lever rigidity and improving braking response. The lever features a simple freestroke adjust, so you can customize when your brakes bite, and pairs up with a refined 4-piston caliper that increases braking power a claimed 10% above the M9020 of last year.

On the business end of things, Shimano employs some similar technology from previous generations, including titanium hardware, and a one-piece aluminum caliper design that is lighter, and better at heat distribution. It employs a mounting bolt that increases stiffness and power, to improve speed and reliability in your braking. They feature Ice Tech radiator pads and insulated pistons that continue Shimano's prowess in heat dissipation, aiming to all but eliminate heat as an issue on long, steep descents that require more braking than normal. Compared to M9000, the new M9120 features quicker brake pad engagement for faster response when you need it.

You may be wondering where the M9120 falls in comparison to the equally new and shiny M9100. While the M9100 may shed grams above the M9120, you'll find that it lacks the adjustability, and some of the stopping power. The M9120 uses two more pistons in the calipers making it more ideal for enduro and trail shredding, while the M9100's minimalist approach slides it to the ideal spot for racing cross country and marathon. That's because 9100 skips the bells and whistles, like Servo Wave adjustment, and free stroke adjust, opting for a more minimalist, but featherweight application.

The Shimano XTR M9120 Brakes come individually, so please order both front and rear sets if you'd like a pair. The brakes were optimized for performance with Shimano's Ice Tech brake rotors, which are not included.
