Shimano XT M8120 Disc BrakeWith its four-piston caliper design giving you extra braking power and modulation, the Shimano XT M8120 Disc Brake enables you to push yourself harder on the trails. 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) 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, N04A Metal (Sintered) with fin 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.

The introduction of Di2 to Shimano’s 105 front derailleur represents a dramatic leap forwards for the Japanese brand’s most popular groupset. Even in its mechanical form, a 105 front mech offered smooth, precise gear shifts; the addition of Di2 to this already exceptional groupset, means your gear changes will be quicker and more reliable than ever. Electronic Shifting For The Masses: Di2 is Shimano’s electronic gear shifting system but until now it had only been available on the Japanese component maker’s top-tier models. In introducing Di2 to the 105 range, the smooth, crisp feel of electronic gear changes are now available to a whole bunch of new cyclists. It’s no secret that Dura-Ace and, even, Ultegra are ultra-premium groupsets, only obtainable by pros and the financially well-endowed. However, no longer is electronic shifting available only to the elite. A 105 Di2 front derailleur has made electronic gear changing more affordable than ever. Over the years, Shimano have continued to review the shape and style of their electronic front derailleurs. The R7150 front mech draws on inspiration from the well-established models. It is sleek and subtle, and will easily enhance any bike it adorns. Synchronized Shifting: The 105 Di2 front derailleur is compatible with Shimano’s Synchronized Shift system. Through this system you can set up your shifting to be full synchronized, semi-synchronized, or manual. In fully synchronized mode if you shift the rear derailleur, the front derailleur can change should it no longer offer an optimum chain line. In semi-synchronized mode, the rear derailleur will automatically adjust when the front mech is changed. In manual mode, you’ll be free to choose when the derailleurs shift. What’s more, the R7150, without any cables to thread, is simple to install and easy to set up. Once you’re up and running with your 105 Di2 system, you’ll wonder how you ever managed without electronic gear changes. Product Features: Programmed chain guide control Shimano Synchronized Shift Top Gear Teeth Capacity: 50-52T Braze-On Weight: 142g (with bolt washer)
