Shimano XT MT8120 Front Hydraulic Disc BrakeWith its four-piston caliper design giving you extra braking power and modulation, the Shimano XT MT8120 Front Hydraulic Disc Brake enables you to attack trails harder. The lever has reach adjustment and can be combined with I-Spec EV gear shifters. The powerful Shimano XT M8120 mountain bike (MTB) brake includes a rider tuneable lever and four-piston caliper for outstanding stopping power as you navigate around the trails. Its caliper decreases rotor wobbling noise and increases its braking power by 10%, so you'll enjoy a quieter and more precise braking set-up. In addition, its lever enables combination with I-Spec EV gear shifters for an action-packed cockpit layout. There's also an adjustable reach that suits any hand size, type of riding and individual rider preferences. This is a perfect choice of upgrade for dominating every descent and shredding around the trails in style.Features: Material: Lever: Aluminium anodised; Caliper: Aluminium painted Brake Type: Hydraulic disc brake Brake Fluid Type: Mineral oil Hose Length: Separate 850mm and 900mm options Single or Pair: Single Use: MTB, Enduro, Trail Caliper Mount Type: Post Mount (mounting bolts included); Brake Lever Mount: I-Spec EV Lever Length: 2 finger Adjustment: Tool-less reach adjustment Piston: 4-piston Brake Pads Included: Yes; Brake Rotor Included No Weight: 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: The 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.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.Four Piston: Disc brake system with the dual diameter opposed-piston caliper design has differently sized pistons in 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.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.Click here to view the Shimano Brake Reference Guide.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.

Less deadband. More positive engagement. A new cam system requires less lever throw to push the pads toward the rotor. That’s great, but there’s more to perfect braking performance than just power. You need control. Many brake systems minimize deadband—but at the cost of modulation. SwingLink solves that with its special cam shape. When the pads contact the rotor, the leverage rate curve is flat and smooth, avoiding that “on/off” brake feel. It’s the perfect balance of power and precision.Useful reach and contact point adjustments for every type of rider.

These bar clamps are sold separately.Technologies: Contact Point Adjustment: Some people like the instantaneous power of a short lever throw. Others prefer the feel of a longer throw. With Contact Point Adjust, you can pick the position you want your fingers to be in when your brakes are engaged. It’s a quick and easy way to customize the feel of your brakes without having to move the pads. It’s also a way to balance both brake levers to feel exactly the same. Power Reserve Geometry: Your fingers pull in a straight line, but brake levers move in an arc. Bottom line: Your fingers typically want to slip off the ends of the levers as you pull. We designed all of our brakes with the industry's lowest X Factor (that's the distance from the center of the handlebar to the center of the lever's pivot). That reduces the lever's inward travel, creating an arc that's closer to your fingers' natural motion and more power is delivered to the brake lever. And, the cool part is, every SRAM and Avid brake lever has it. Timing Port Closure: A hydraulic brake’s timing port is the connection between the reservoir and the lever cylinder bore.
