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.

The consistent stopping power provided by Shimano’s latest 105 BR-R7170 hydraulic disc-brake calliper makes bike riding that much more enjoyable; regardless of whether you’re descending mountain tops in the wet or racing your friends in the dry, you’ll get the stopping power you’d expect. The 105 hydraulic disc calliper represents the most cost effective way to experience the excellent stopping power offered by Shimano’s performance-oriented disc-brake systems. Although slightly heavier than Shimano’s top-tier models, it offers similar levels of performance to them. So, if you want premium-level performance, at a more reasonable price point, these callipers are certainly worth consideration. Better Braking All The Time: It’s no secret that more and more bike makers are prioritising disc-brake bikes and that an ever increasing number of riders are experiencing the performance benefits of disc brakes. It’s no surprise why, the benefits of disc brakes are numerous: consistent stopping power in the wet or dry; no risk of over-heating and damaging expensive carbon rims on long descents; better brake modulation; and it enables manufactures to make wider wheels, that accommodate larger tyres. Braking Excellence: In the updated BR-R7170 calliper, Shimano have improved the heat dissipation and overall braking control. Whether you’re descending an alpine mountain in the blistering sun or making a sudden stop in the rain, you can rest assured your brakes will work all the same. Further improvements have been made by the Japanese component makers. Pad clearance has been increase by 10%, which will reduce the noise that can occur with disc brakes. Attention has also been paid to the maintenance and bleeding process, which have been improved to make home maintenance a simpler process. A convenient one-way bleeding system, combined with an easy hose joint system, makes for simple installation and adjustment.

The Shimano 105 R7150 Di2 groupset is perhaps—without exaggeration—the most hotly anticipated groupset of the century. Even in mechanical form, the 105 series is widely regarded as one of the most reliable and affordable performance groupsets, with the introduction of electronic the gap between the brand’s mid-tier range and its top-tier is now closer than ever. A Battery For The Ages: The introduction of wireless shifting might leave you feeling concerned you’ll be forever charging batteries and living in perpetual fear you’ll be stranded in you biggest gear miles from anywhere. But with 105 Di2, power is supplied via two CR1632 coin cell batteries in the shifters, which should provide over three years of life. With such a range, even the heaviest of users shouldn’t find themselves in a constant state of charging and re-charging batteries. Semi-wireless Setup: 105 R7150 uses the same semi-wireless, 12-speed shifting setup as the top-tier models. The proprietary semi-wireless system means there is no longer any need from wires to the shifters to the derailleurs. Since there’s no need for wires and cables, the cockpit of a bike set up with 105 Di2 is cleaner and less cluttered than ever. Shift Into Gear: Of course with the change to electronic gearing, one of the most significant changes to the groupset is in the shifters themselves; the all-new 105 ST-R7170 levers now operate in much the same way as the top-of-the-line shifters. Shifting gear couldn’t be simpler: click a button on the shifter and almost instantly you’ll hear the derailleur whir into life. Drawing on Shimano’s years of experience in electronic shifting, you can expect smooth gear changes at the touch of a button. Without the need to accommodate levers, wires, or ports, the shape of the R7150’s levers has been brought more in line with the sleeker Ultegra and Dura-Ace shifters. The new, slimmed down, STI levers are also more ergonomically shaped, thanks to the raised hood peak and offer more opportunity to refine the reach. The Brains Of The Operation: Another significant change to previous mechanical setup is in the front and rear derailleurs. The rear derailleur is an integrated, 12-speed wireless unit, which will comfortably accommodate an 11–36T cassette. Such a wide range of gears is perfect for those big climbing days, without spinning out when the road tips back down or when you’re racing along in fast bunch rides. The rear mech uses Shimano’s Shadow technology is incorporated to reduce the risk of the derailleur hitting the chainstay in rough-riding conditions, and to provide smoother, quieter performance. The 105 Di2 front derailleur offers the smooth shifting you’d expect from the Japanese component makers. It can be programmed to be manual, or full or semi-synchronised, accommodating a 50T or 52T chainring. Crank It Up: Shimano continue to deploy their famed Hollowtech II technology in the R7100 crankset, which is now 2x12-speed. This is the same technology they have employed in the 105 range for years, and features also in the company’s premium lines. The result is a sturdy crankset, that is stiff and relatively light. Incorporated also is Hollowglide technology, which offers more precise and efficient power transfer than ever before. Shimano have been able to reduce the weight of the crankset but maintain stiffness, strength, and performance. For 105 Di2, cranksets are available as a compact (50-34 tooth) and in crank-arm lengths of 170, 172.5 and 175mm Stopping Performance: The 105 hydraulic disc brakes of the previous iteration were highly capable; for the latest ST-R7170, Shimano have further improved braking performance. The lever-action required for braking is now lighter and smoother, offering a greater area for braking control. For 105 Di2, the clearance for pads has been increased by 10%, reducing braking noise. Overall, rain or shine, you can be assured of high-performance stopping power.
