Order the Shimano 105 Di2 R7100 Groupset from today. Shop North America's biggest and best selection of Shimano 12-speed group-sets at The all new redesigned Shimano 105 Di2 R7100 Groupset provides the reliability of the Ultegra and Dura-ace groupsets but at an accessible price point.

We recommend upgrading the Rotors (RT-MT900) and crankset (FC-R8100) both for performance, longevity and weight savings.

The Shimano 105 Di2 R7100 Groupset delivers the workhorse durability for which 105 is known, but with state-of-the-art electronic shifting. Using the latest Shimano technology, this groupset features a 12-speed cassette and a wireless cockpit, providing a wide gear range and a simple setup. 

Much like the top-shelf Dura-Ace and Ultegra Di2 offerings, shifting is customizable through the use of the accompanying Shimano E-Tube PROJECT mobile app, allowing you to adapt it to your preferences. The braking system is revamped, ensuring superior performance and less noise. The bleeding process has also been improved, ensuring overall ease of maintenance.
