Product Details

Shimano R7100 105 Di2 12 Speed Disc Groupset

Shimano 105 Di2 utilizes a hybrid system, featuring a wireless cockpit paired with a wired connection between a single, seat-tube-stored battery and the front and rear derailleurs, ensuring absolute reliability in all conditions. And just like Dura-Ace and Ultegra, the Shimano 105 Di2 system is highly customizable using Shimano’s user-friendly E-TUBE PROJECT Cyclist App on your smartphone.

By making the move to a 12-speed cassette, Shimano 105 R7100 Series riders now have the high and low gearing they need, along with an intelligent progression of gear steps in between.

Just as with the latest Dura-Ace and Ultegra groupsets, the new Shimano 105 features a revamped braking system that’s quieter, easier to maintain, and supremely controlled and powerful. Top line features include a fast initial contact point with a wider control zone and 10% wider pad-to-rotor clearance to help avoid brake noise.
