Shimano 105 R7170 Di2 2x12 Speed Shifter Set

Function and technologies inherited from Dura-Ace and Ultegra, Shimano 105 is the culmination of years of research and development. With a shared Di2 platform, sophisticated ergonomics, Shimano 105-optimized gear combinations, and an exceptional brake system, the new Shimano 105 marks a new era of affordable performance. Sleek wireless cockpit brings simplicity and clean aesthetics. Wireless connection enhances the aerodynamic effect and easy maintenance.

Never skip a shift as you fatigue or encounter an unexpected climb. Worry-free Di2 shifting and a compact R7100 series shifter keeps you in control in any situation. The difference is made over the course of a ride, saving you energy with every gear change, allowing you to focus on the scenery, your effort, and your friends.

The all-new lever shape brings comfort and control in every riding position. Raised hood peak improves ergonomics, while a longer hood body increases hand support. Compact, ergonomic performance, custom button function and adjustable ergonomics cascaded from Dura-Ace.

Shifting is automatically completed at the touch of a switch, eliminating the need for the amount of stroke required for mechanical shifting. The rider can shift into the most appropriate gear at will, depending on the ever-changing conditions, speed, and road surface. This is a great advantage not only in the world of racing, but for all cyclists.

With a new piston design, race-ready braking is now available for even more riders. The new Shimano 105 BR-R7170 brake caliper allow riders to progress in their cycling journey by learning the joys of braking and pushing their limits with better sensitive braking control in a wider control zone and 10% wider pad clearance.

105 ST-R7170 is compatible with wireless connect and easy to change of CR1632 shifter batteries that provide high electronic energy efficiency of 3.5 to 4 years of battery life.
