Shimano 105 ST-R7170 + BR-R7170 Hydraulic Disc Brake - Di2 | 2x12 Speed - Rear Set
105 R7100 / R7150 – It's A New Day
Marking the 40th anniversary since its market launch in 1982, the 105 series receives its latest update with Shimano's electronic Di2 shifting technology. Maintaining the standard price level, the precise shift function, precisely tuned gear ratios and a reliable braking system are made accessible to an even wider circle of road cyclists. Following in the tradition of its predecessors, today's 105 is also packed with cutting-edge technologies – like the wireless cockpit – and premium features from the next-generation Dura Ace and Ultegra series so your riders can discover the road anew, every day. .


STI Shift/Brake Lever Shimano 105 Di2 RD-R7170
As with the current STI shifters from the Dura Ace and Ultegra series, Shimano has once again worked with professional riders to develop the 105 series 2x12 electronic control units. Not only has a Wireless system been introduced to ensure a neat and wonderfully minimalist cockpit, but also the ergonomics have been extensively refined. Characteristic of the revised aesthetics and aerodynamics are, above all, the raised rubber lever horns, which prevent fatigue regardless of hand position and guarantee first-class comfort.

But the compact Dual Control levers are also convincing on the technical side. While the reach adjustment mechanism makes it possible to adapt to different hand sizes or riding styles and thus promises more control in racing, the button functions that can be individually assigned via the E-Tube app They benefit an essential task of the controls: the performance of the change. A proprietary circuitry ensures safe and fast signal transmission, which not only enables more precise and direct gear changes, but also more intuitive gear changes in manual mode. Athletes who want to dedicate themselves fully to competition can also leave gear changes completely or at least partially in the hands of Synchronized Shifting technology.

Switching to electronic Di2 gearing naturally also offers decisive advantages in terms of ease of maintenance. With a battery life of at least 3 years, the rider also doesn't have to worry about powering the wireless shift/brake levers. Speaking of brakes, the smooth-operating Servowave brake levers have also received a significant upgrade in terms of metering and deceleration performance with an extended range of control.

Shimano 105 BR-R7170 Disc Brake Caliper
Thanks to the natural deceleration feel of the Shimano BR-R7170 hydraulic brakes, athletes can push their limits even further. While their flat profile makes Flatmount disc brake calipers ideal for use on road bikes, a 10% larger pad spacing compared to the previous model reduces the risk of unwanted friction and brake drag. brake discs.

This reduces overall noise during deceleration without compromising brake performance. By contrast, the BR-R7170 brake calipers not only fit quickly, but also fit reliably. To keep maintenance to a minimum, the proven One-Way-Bleeding system is used again, with a simplified bleeding process that eliminates the need to remove the caliper from the frame.

J-Kit (Easy Hose Joint System) | On brake systems with a J-Kit brake line connection, the brake lever has an integrated pinch seal (olive), which greatly simplifies overall brake line installation and removal.
