Shimano ST-R7170 105 Double Hydraulic Di2 LeverBringing electronic wireless Di2 shifting to a new set of riders, this shift/braker lever combines industry-leading functionality with trickle-down technologies from the Dura-Ace and Ultegra series. After years of research and development, Shimano's 105 series now offers Di2 electronic shifting for the first time, bringing precise, intuitive gear changes to even more riders. Not only does it offer worry-free Di2 shifting in a compact shifter size, but it also features technologies such as Reach Adjust and customised button functions that allow you to dial in your ideal ergonomics. For those who have only experienced mechanical shifting and ergonomics, this model marks a new era of affordable performance.Reach AdjustThis model's 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.E-Tube ProjectShimano'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 LeverDCL 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.Features: Shifter Type: Dual Control Lever (DCL) Use: Road Speed: 12 speed Di2 Connectivity: Wireless Di2 shifting Battery Type: CR1632 x 2 Recommended Brake Caliper: BR-R7170 (available separately) Brake Lever Clamp Band: 23.8 - 24.2mm Firmware Update by E-Tube Project: Yes Mineral Oil: Shimano Mineral Oil Adjustments: Reach Adjust, Free Stroke Adjust, Funnel Bleeding Single or Pair: Single, sold individuallyTechnologies: Clean Cockpit: Wireless connection enhances the aesthetic of your bike while keeping shifting lightning fast.

Shimano 105 Di2 ST-R7170 Hydraulic Disc Brake STI Lever The introduction of 105 Di2 shifters is perhaps the biggest shake up in gear changing since the invention of electronic shifting. With the 12-speed ST-R7170 shifters on your handlebars, smooth, quick electronic gear changes are now quite literally at your fingertips. The 105 series is easily Shimano’s most popular groupset; favoured by cyclists across the world, adding Di2 to the range puts electronic shifting in reach of many a cyclist to whom it was previously unobtainable. With 105 Di2 shifters, not only do you get fast and precise shifting every time you click the button, you’ll also get the braking performance to match. Perfect Shifting At The Touch Of A Button: Introducing Di2 to 105 naturally means one of the most evident changes can be seen in the shifters. Since gear changes are performed electronically, of course, there is no longer any need of a lever to pull cable through. Instead you change gear effortlessly at the touch of the button. Simply click the button, and listen out for the derailleur whirring into life. Via Shimano’s app it is even possible to customise your preferred shifting pattern, whether that’s faster or slower. Ergonomically Minded, Cleaner Look: In addition to introducing electronics to the shifters, the refinement of the shifters’ shape is further evidence of the thought that’s gone into this product. Without the need to accommodate the mechanical devices of the non-Di2 version and based on pro feedback, Shimano have slimmed down the design of the 105 Di2 lever and increased the height of the hood’s hook to improve the ergonomics of the shifter. The enhancements bring ST-R7170 closer in design to the more premium Dura-Ace and Ultegra lines. The combination of a slimmed down shape and absence of wires and ports means that the cockpit area is cleaner than before. So whether it’s the minimalist appearance you crave or it’s more space for accessories you’re looking for, everyone’s a winner. Braking Excellence: Braking control, while already stellar on the previous R7000 model, has also received a boost in performance. The 105 R7170 levers provide exceptional braking performance and control. The lever action is smoother and lighter than before, and the braking control area has been increased too. Battery For The Ages: Finally, if you’re concerned about forever being in a state of charging and replacing batteries, fear not. The two CR1632 batteries required are good for up to three years, which should provide enough power for even the most ardent users.

More compact and lighter than ever, the R7170 brakes offer wide pad clearance for easy wheel removal and quiet performance as well as one-way bleeding for easy, clean maintenance. 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. Shimano 105 Di2 brings electronic wireless shifting to a new set of riders.

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. Manufacturer's Part Numbers: R7170DRF Black Front Right R7170DLR Black Rear Left
