Shimano XT M8100 Rear Brakes

DEORE XT – Durability and performance for today´s mountain bikers

– The new DEORE XT M8100 series includes innovative features such as the MICRO SPLINE sprocket cassette with 10-45T or 10-51T teeth development, 1×12 or 2×12 HOLLOWTECH II crankset , powerful 2-piston and 4-piston brakes, adjustable ISPEC-EV shifters, 12-speed rear derailleur and derailleur, ICE TECHNOLOGIES FREEZA fast-cooling rotors and complete wheel sets for XC or Enduro, all adjusted to The needs of mountain bikers today.

– Brakes: The DEORE XT brake calipers are available in a 2-piston version specific to XC and in a 4-piston version for Trail / Enduro. The 2-piston version shares the same design as the previous XT M8000, which means that the G02A / 3A / J02A / 3A resin pads and the G04S / J04C metallic ones are compatible, while the 4-piston version is completely new, inspired by the XTR M9100, with which it shares the N03A (resin) and N04C pickups (also compatible with D03S and D02S).

– The DEORE XT brake levers work with both XC and Trail / Enduro calipers and are equipped with Shimano´s SERVO WAVE system for faster coupling, improved power and faster response. The levers now come in two positions on the handlebar to provide a stiffer braking sensation. They also have dials that allow the braking adjustment during the ride.

– The XC brake kit (BR-M8100-BL-M8100) with rotors (160 mm RT-MT800) and pads weighs 392 g and the Enduro kit (BR-M8120-BL-M8100) weighs 410 g, including rotors and pads.

Technologies:

– ICE TECHNOLOGIES: Loss of overheating braking efficiency, which can occur in the brake disc and the pad when braking on long descents, for example, has a negative impact on braking performance. SHIMANO has adopted the ICE TECHNOLOGIES brake disc and the ICE TECHNOLOGIES pad to make cooling technology a reality that provides reliable performance. The coated brake disc blade, which has a 3-layer sandwich structure of stainless steel, aluminum and stainless steel, provides better radiation performance and allows 400 ° C to 300 ° C surface temperature. Likewise, a radiation fin has been adopted for the tablet. In addition, the coated brake disc blade and the radiator fin offer a long service life of the pad, less noise,

– ICE TECHNOLOGY pickups: Available in resin or metal compound, the optional radiation fin pickup with 2-layer backplate (aluminum fin with stainless steel) further improves radiation performance.

– ICE TECHNOLOGY piston to achieve optimum weight, high rigidity and heat dissipation. The oversized pistons directly transfer hydraulic power to the brake pad and the ceramic material is used to prevent heat transfer in order to obtain a stable steady braking, providing efficient lossless braking power transfer

– “ONE WAY BLEEDING” has been developed for a quick and easy prevention of the presence of air in our hydraulic system. We have streamlined the route of the oil in the system to avoid air bubbles in the system. The one-way oil path, plus a funnel tool with mineral oil, provides an easy and clean purging system.
