Ready for aggressive mountain bike rides, the Shimano XT M8000 model features an aluminium lever and caliper construction. This makes it more than capable of handling all the abuse from trailside obstacles and bumps from the rocky terrain. Shimano has also gone a step further by giving this MTB disc brake's lever an anodised finish. This means you'll benefit from an extra layer of durability and corrosion resistance as you weave between the mountain bike trails in all weather conditions. Adjustable MTB Disc Brake Designed for ease of use, this MTB disc brake is kitted out with an adjustable lever reach. This allows you to fine-tune the distance between your handlebar and the lever to perfectly match your hand size, riding style and terrain conditions. As a result, the Shimano XT M8100 Disc Brake is an excellent choice of upgrade for riders who want a more customised braking feel as they blast across the mountain bike trails. Technologies: Servo Wave Action: When you pull a Servowave brake lever, initial pad travel is fast, so little lever movement is needed to bring the pads into contact with the rotor. The power multiplication factor then increases rapidly at the pad-to-rim contact so more of the lever stroke is used to apply greater braking power with improved control. Reach Adjust: Brake lever is equipped with a reach adjust mechanism. The distance from the handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences. Free Stroke: The distance from the initial lever position to pad contact point can be adjusted to suit any hand size, type of riding and individual rider preferences. Ice Technologies: The fade, which can occur to disc brake rotors and pads when braking on a long downhill ride, has a negative impact on the braking performance. Shimano has adopted Ice Technologies disc brake rotor and Ice Technologies pad to realise the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminium and stainless steel, provides better radiation performance achieving from 400˚C to 300˚C surface temperature. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight. One Way Bleeding: One Way Bleeding was developed for quick and easy prevention of air in Shimano's hydraulic system. Shimano has streamlined the oil route throughout the system to prevent air bubbles from being captured in the system. One-way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.

This stunning model features quicker piston retraction for instilled downhill confidence and modulation as you shred the trails. Its four-piston construction is specially engineered for conquering every off-road ride as it gives you versatile high-performance braking control. Technologies: Four Piston: A disc brake system with the dual diameter opposed-piston caliper design has differently sized pistons in the front and in the rear. The system adopts a power transfer system in which the disc brake rotor is pressed by the smaller sized piston at the entrance of the disc brake rotor intake and also by the more powerful larger sized piston at the back. This prevents the wobbling motion of the disc brake rotor and reduces noises significantly. The 4-piston caliper also allows a wider contact area for the disc brake rotor while keeping the size compact, and the efficient location of pads is adjusted as necessary to stabilise the pressure. In combination use with the Servowave lever it provides an incredible 50% more stopping power than the previous model. The advanced Saint/Zee disc brake system, which adjusts to accommodate the different braking styles of different riders, offers stable braking power and excellent modulation. Ice Technologies: The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride for instance, has a negative impact on the braking performance. Shimano has adopted Ice Technologies disc brake rotors and Ice Technologies pads to realise the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminium and stainless steel, provides better radiation performance achieving from 400˚C to 300˚C surface temperature. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight.

The Shimano Ultegra R8100 series caliper brakes offer a clear contact feeling while balancing rigidity, weight, and stopping power. With increased clearance for 28mm tyres, the sleek design is still fetching. Powerful and Responsive Shimano SLR-EV Braking Efficiency SLR-EV is Shimano's SLR braking technology with a dual symmetric pivot brake caliper. The short-arm brake design employs two bearings and a roller to realize greater efficiency in the pivot area and deliver superior modulation and power for braking. Together with the BC-9000 brake cable, the latest calipers deliver 36% more braking power than Shimano's previous brake model.

To ensure that the signal goes from the shifter to the derailleurs, the reliability of the electric cable has been proven by repeated field tests in various riding conditions, including extreme temperatures, rain,mud, and cobble stone roads. The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts. Dura-Ace Di2 requires 2 cables: a handlebar cable set to connect the shifters to a battery indicator junction box or FlightDeck, and the other to connect the handlebar cable to the battery and derailleurs.
Perfect for keeping you in control of your road bike adventures, this model features a heat management system and an Ice Technology pad within the fin. This combination reduces heat build-up and allows you to benefit from consistent braking efficiency as well as excellent longevity. Designed to offer wide pad clearance and easy tool access, this is a great upgrade for riders that want a straightforward and easy to fit brake caliper for their road bike. Item Top Features Continued: Recommended Brake Rotor: SM-RT54/RT56 (160mm); RT-MT800 (140mm/160mm) Single or Pair: Single Part Numbers: Front: BRRS305F; Rear: BRRS305R Technologies: New Super SLR: SLR stands for SHIMANO Linear Response. The NEW SUPER SLR design makes use of a friction-reducing mechanism in the caliper, lever and cable that improve response and modulation. Also for the lever, the SERVOWAVE mechanism is adopted to provide quick contact of shoe to rim and longer stroke from the initial braking effect for better control. SLR is the essential factor in the SHIMANO dual-pivot caliper that deliver more braking power than conventional side-pulls. Road Disc Brake: Road Disc Brakes deliver consistent brake performance in any weather, with lighter lever action and greater brake power control for a wide range of riding styles. Ice Technologies: ICE TECHNOLOGIES piston in order to achieve optimized lightweight, high rigidity and heat dissipation. Oversized pistons transfer hydraulic power directly to the brake pad, and ceramic material is used to avoid heat transfer for constant stable braking, providing efficient stopping power transfer without loss.
