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 handlebar and creates an additional abutment when the lever is actuated. This significantly increases stiffness and stability, which ultimately leads to an even more direct braking feel and improved controllability.
The two-piston brake (BR-M9100) comes in combination with a light XC brake lever, whose grip width is of course individually adjustable. The four-piston brake (BR-M9120) recalls its immense potential in combination with a special SERVO-WAVE brake lever (BL-M9120), whose grip width can also be adjusted without tools and which also has an adjustment option for the free travel. Both calipers have a one-piece aluminum design and are combined with highly rigid brake lines, so that the new XTR brake systems score with significantly faster response and less free travel.
The brake pads and brake discs have also been revised to match the newly developed brake calipers. The four-piston brakes use brake pads with cooling fins. (N03/04A, resin/metal).
On the other hand, the pads without Kührippen (K02/04S, resin/metal; optionally K02/04Ti with titanium carrier plate) ensure good deceleration with low weight. The design of the brake discs is a further development of the successful ICE TECHNOLOGIES FREEZA design. While the further weight reduction of 5g and 10g is particularly attractive for the 140mm and 160mm discs, the 180mm and 203mm versions are characterised by a further improvement in heat dissipation of 20°C in intensive tests and are also pleasantly low-weight (203mm: minus 30g).
