When Shimano released a brand new 12-speed group, we'd be lying if they told you that we don't want to see every little piece of the puzzle. Certainly We are delighted with the cassette and the completely new shift system but we also wanted to see what improvements were ready to race touched on other components such as the XTR BLM-9100 disc brakes. M9100 disc brakes matching the XTR 9000 Race models of yesteryear, bring pure a minimalist approach to your cabin both thanks to the sleek, no-frills appearance and in its featherweight class, which is 26 grams lighter than its predecessor. - all without compromising XTR's next-level stopping power.

Shimano has made some major changes to the design of the cockpit-side brake kit , as in the design as well as the location of the brake levers. They use a new magnesium master cylinder to reduce grams and are equipped with I-Spec EV which moves the clamp inward compared to the previous I-SPEC design so that the new master cylinder contacts the rod. This additional point of contact increases rigidity , improving braking performance and improving control when you drive through your head entering a sharp turn. In addition to the new I-Spec configuration Shimano uses a new brake lever shape with ergonomics in mind allowing comfortable braking with two fingers for smooth operation. Shimano claims that the new brake design provides a whopping 10% increase in rigidity over the M9000, even in high temperature conditions.

You may also have noticed the Shimano M9120 brake kit on our website and you might be interested where M9100 is in comparison. Compared to previous years The M9100 corresponds to the Race model, while the M9120 is more similar to the Trail model. It means that while the M9120 has almost all the functions such as servo wave adjustment and free play adjustment M9100 chooses clean, smooth minimalistic design. Although you can still adjust the arms with a tool in a shop or home garage M9100 is not designed for on-the-go adjustments which allows for significant weight reduction. At the rear, the M9100 uses a lighter 2-piston system which provides more than enough stopping power for your XC setup while the more powerful M9120 opts for a 4-piston system necessary for stopping heavier enduro rigs. Both have been optimized for the latest Shimano Ice rotors
Tec Freeza allowing heat to be removed as quickly as possible even at high speeds.
