Shimano R7100 105 Di2 12-Speed Disc Groupset

The new SHIMANO 105 brings Di2 shifting to a new set of riders. For those who have only experienced mechanical shifting and ergonomics, SHIMANO 105 Di2 represents a transformation of the road cycling experience.

With 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.

Shift With Ease

Never skip a shift as you fatigue or encounter an unexpected climb. Worry-free Di2 shifting and a compact shifter size keep 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.

A Drivetrain For Diverse Riders

Helping you meet the road with 12-speed gearing and low-climbing ratios. Here is the low gear that you've always wanted. 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.

Slowing Down Never Felt So Good

With a new piston design, race-ready braking is now available for even more riders. The new SHIMANO 105 braking system allows riders to progress in their cycling journey by learning the joys of braking and pushing their limits.
