Shimano 105 Goes Semi-Wireless Di2 With The 7100 Series
The Shimano 105 ST-R7170 Di2 Shifter W/ BR-R7170 Disc Caliper set is a lever/caliper combo that is ready to mount on your bike.
The Shimano 105 ST-R7170 shifters are semi-wireless, and utilize Shimano's proprietary integrated circuit that features high security, fast processing speed and low power consumption.
Contrast that with other wireless platforms and you get a significant decrease in interference probability, faster shift speeds, and longer battery life. And by using a single, internally housed rechargeable battery, charging is straightforward, and the battery is protected, further ensuring stable and reliable shifting at all times.
The Shimano 105 BR-R7170 brake calipers inherit the same revamped qualities of the latest Dura-Ace and Ultegra groupsets—they are quieter, easier to maintain, and supremely controlled and powerful.
The calipers include a fast initial contact point with a wider control zone, and 10% wider pad-to-rotor clearance assuring noiseless operation.
Home mechanics will also appreciate a more user-friendly bleed process, which can be done without removing the caliper from the frame.
The new Shimano 105 12 Speed di2 groupset brings the benefits of semi-wireless electronic drivetrains to their workhorse line of components.
Pro level features are now available for every-day cyclists.
