Shimano 105 Di2 R7170 2x12 Speed Upgrade Kit

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.

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.


Easier on the hands: Comfortable compact hoods

Easier on the hands: Short-travel shifting

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.

Shimano 105's sub-1:1 ratio 12-speed range is a tool that lets riders take on steeper slopes and better control their effort along the way with Shimano FC-R7100-12 crankset pairing with CS-R7100-12 or CS-HG710-12 cassette, and RD-R7150 rear derailleur supporting the cassette ratio of 34T-36T.

One-hand shifting that can be personalized to match your riding style

Enjoy simple, one-hand control as the Shimano 105 FD-R7150 front derailleur is automatically kept in synchronization with the 105 RD-R7150 rear for consistent pedaling efficiency and stress-free shifting. You can personalize it to match your riding style in the E-TUBE Project app.

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.
