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.
