Shimano XT M8100 Mountain Bike Disc BrakeThe stunning XT M8100 Mountain Bike Disc Brake from Shimano combination features a two-piston caliper and a rider tunable lever for outstanding stopping power on the trails. Its lever gives you an action-optimised cockpit layout for greater flexibility while its reach adjustment suits any hand size. Its caliper offers quicker piston retraction for superior modulation and control, so you'll benefit from a more efficient braking set-up. This lightweight and easy to install model is ideal for taking your off-road adventures to the next level.Features:Material: Lever: Aluminium anodised; Caliper: Aluminium paintedUse: MTB (mountain bike)Caliper Mount: Post MountLever Length: 2 fingerAdjustment: Tool-less reach adjustmentPiston: 2-pistonPads: G03A Resin without finBrake Fluid: Mineral oilWeight: 284g (approx)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 to 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 rotor and pad 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 our hydraulic system. We have 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.Click HERE to check out the Shimano Brake Reference Guides.A 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

The distance from the handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences. E-Tube Project: Shimano's genuine application E-Tube Project Cyclist allows you to customise your bike, update firmware, and maintain it by connecting it wirelessly to your bike. You can also get the more detailed bike maintenance by connecting to your bike by wire with E-Tube Project Professional application. Dual Control Lever: DCL stands for Dual Control Lever. It has brake and shifting functions in the system and enables easy operation. Ergonomic innovation is probably more critical to the higher standard performance than the added gearing. The shift internals borrow the robustness from Shimano's MTB technology and are so smooth and effortless that one finger shifts front and rear are possible. Indeed, shifting is the ultimate act of Shimano Total Integration, and simply has to be experienced to be understood. 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 the Ice Technologies piston to realise the cooling technology for consistent performance. 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. This model's Ice Technologies piston achieves optimised lightweight, high rigidity and heat dissipation. One Way Bleeding: One Way Bleeding was developed for quick and easy prevention of air in the 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. Hollowtech II Technology: Providing the best balance of stiffness, strength, weight and rotating performance, the concept of Hollowtech II technology is focused on producing a superior crankset that will maximise your power transfer. The rigidity of the crankset ensures pedalling efficiency while its weight, a key element of the crankset, you want light, aids in cycling longer distances where you need to pedal more. Moreover, the Hollowtech II crankset has a high-precision sealing in the bearing area to increase durability maintaining the excellent rotating performance for long periods. Hollowglide Technology: This model features Hollowglide technology on its outer chainring. High rigidity hollow structure cuts down on weight yet maintains strength. Better power transfer and quicker and more precise front shifting. Digital Integrated Intelligence: The revolutionary DI2 shifting system solves the challenges drivetrains present to the power-delivery equation in cycling. DI2 gives you instant, accurate, lightning-fast shifts the first and every time, at the push of a button. Even in the most extreme conditions, shifting is precise and controlled. You can change gear even under heavy load while climbing or accelerating. With DI2, you are in complete control.

You can also get more detailed bike maintenance by connecting to your bike by wire with the E-Tube Project Professional application. E-Tube Ride: Shimano's E-Tube Ride application allows you to visualize your ride with a route map to your destination, a real time ride data display, and ride record data on your smartphone while you are on your bike. You can also upload your ride log data to Strava.Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
