This Shimano Di2 Bluetooth frame or bar plug mount allows you to charge and check the battery level of your Shimano Di2 electronic shifting system. Thanks to its Bluetooth-compatible design (Bluetooth module available separately), you can easily connect to your Shimano Di2 to change shift modes such as manual shift, synchronized shift 1 and synchronized shift 2. Its built-in LED lights will illuminate to indicate the mode you have selected by a green or red light system. If your bike receives a strong impact, the rear derailleur (RD) protection function kicks in and the connection between your motor and the link is momentarily severed so that the rear derailleur will no longer operate. This is done in order to protect the system at times such as if the bike falls over. The Shimano Di2 junction box allows you to press the button on junction (A) to restore the connection between the motor and the link and to clear the RD Protection function for the rear derailleur. To top it off, this handy device features water-resistant connectors so you can keep your Di2 running in peak performance, whatever the weather conditions. Please note: You need the additional Bluetooth module Shimano SM-EWWU111 to enable Bluetooth. This Shimano SM-EWWU111 unit allows you to connect to a Bluetooth device once installed however, the EW-RS910 alone does not allow for this functionality and would work in tandem with the Shimano SM-EWWU111.

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.

Bleeding Edge: Bleeding Edge technology makes bleeding brakes quick and simple. An updated fluid path and bleed porting make it easier to push fluid through the caliper. A dedicated bleed adapter plugs into the bleed port and seals the system to minimise air contamination and fluid loss. Direct Link: SRAM's DirectLink lever design produces a solid, positive feel the second you squeeze the lever to engage the brake It offers a no-nonsense solution to give you precise control. Lever Pivot Bearings: Precision sealed bearings at the lever pivot enhance the clean, crisp lever actuation and consistent, light, one-finger feel. Expandable Bladder: SRAM's brake lever design includes a reshaped bladder that helps regulate and reduce air bubbles. The bladder is specifically shaped to evacuate air from the lever and push the fluid exactly where it's needed. The result is improved back-pressure relief, which produces dependable braking power and consistency. Timing Port Closure: A hydraulic brake's timing port is the connection between the reservoir and the lever cylinder bore. When the lever is squeezed, a cup seal passes this area and closes the port, which pressurizes the system. SRAM's timing port closure system features durable seals and an ultra-smooth cylinder bore finish producing reliable braking performance.Buy SRAM 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. SRAM design its brakes to give each individual rider distinct control of their ride.Added stiffness in the caliper and a new pad compound that offers more bite and really delivers the Mini-Code feel.Engineered for easy installation.Features: Lever Blade Material: Aluminium - Stamped Piston Material: Phenolic Plastic Pad Type: Steel-backed Organic Use: Mountain Bike (MTB) Brake Type: Hydraulic disc brake Number of Pistons: 4 Recommended Rotor Type: 1-piece CenterLine (available separately) Recommended MMX Clamp: Stainless bolt, blk clmp (available separately) Single or Pair: Single Weight: 248gPlease Note: This brake is designed for use with a Matchmaker clamp (combined with shifter) so does not come with its own bar clamp. 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. When the lever is squeezed, a cup seal passes this area and closes the port, which pressurizes the system. SRAM’s timing port closure system features durable seals and an ultra-smooth cylinder bore finish producing dependable braking power and consistency.Buy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
