Shimano XT M8100 12 Speed ShifterThe light and responsive XT M8100 12 speed shifter from Shimano is perfect for MTB (mountain bike) use as it improves your speed, control and concentration. Shift both up and down with ease using a single lever and enjoy the instant push and pull movements as you conquer the trails. Featuring a compact design combined with top technology from Shimano, this Speed Shifter is a perfect upgrade for quick and easy-shifting performance.Features:Front Speed: 2Rear Speed: 12Max Multiple Shifts: 4Release Function: 2-Way Release, Multi Release, Instant ReleaseShifter Type: Rapidfire PlusMount: I-Spec EV and Band On options available to selectAverage Weight: 78g (Left); 117g (Right)Technologies:SIS: Shimano Indexed Shifting. It's the technology behind that "click" you hear and feel every time you shift through your gears. That "click" captures the light, precise, and consistent shifting bikes equipped with Shimano deliver. It's the sound of perfect gear changes, of levers directing derailleurs in harmony and the feeling that resonates into your hand, letting you know that your commands are being answered. Whether you ride for fun, fitness, commuting, or competing - and on pavement or trail - Shimano S.I.S is a foundation of your cycling experience.Rapidfire Plus: Mountain bikers have used Rapidfire Plus since 1985. Rapidfire Plus is still a winning choice from a wide range of riders from XC racers to free-riders. Rapidfire Plus is suited to quick shifting, giving riders the ability to downshift three gears in one stroke. Rapidfire Plus shifters from Deore to XTR all feature 2-way Release, which means release shifts by a pull of the index finger or push of the thumb.2-Way Release: The Rapidfire Plus shifter release lever is commonly called a trigger because it is operated like a pistol, by pulling toward the grip. The release lever of Rapidfire Plus shifters from Shimano Alivio to XTR can be operated in this same manner but adds the ability to activate a release shift by pushing with the thumb.Instant Release: Instant Release shifting replaces the two-stage click and release shifting you are familiar with. Instant Release shifting releases cable as soon the lever is activated, resulting in the quickest possible gear changes. Whether it is an upshift with a top normal rear derailleur or a downshift with low normal rear derailleur a quicker shift is always a better shift.Multi Release: Previous shifting systems shifted faster in one direction than the other. Choosing top normal or low normal always meant sacrificing shifting speed in one direction. Now with Multi Release you can release shift two gears in one stroke. The result - the fastest possible shifting in both directions regardless of rear derailleur choice.Rapidfire Plus Mono: The Rapidfire Plus Mono lever provides intuitive and simple front control that empowers riders to shift both up and down with a single lightweight and compact lever. Simple and intuitive single lever operation, quicker access and lighter front shifting enhances concentration. Front double shifting with natural finger positioning supports intuitive shifting operation. Easy front shifting helps riders quickly and accurately respond to rapidly changing conditions.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.
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.
