The Shimano 105 Di2 R7100 marks a major advancement by making electronic shifting more accessible to cyclists seeking performance and reliability. Designed to compete with the SRAM Rival AXS, this groupset offers the benefits of Di2 12-speed technology at a more affordable price.
Building on the technology of the Ultegra R8100 and Dura-Ace R9200 groupsets, the Shimano 105 Di2 R7100 features a 12-speed architecture, delivering smoother shifting and better adaptation to different pedaling cadences.
It utilizes a semi-wireless design, where the shifters and derailleurs communicate independently, while the derailleurs are wired to a battery to ensure optimal battery life.
Shifters
The Shimano 105 Di2 shift levers maintain the same ergonomic design as the higher-end models, providing a comfortable and intuitive grip. While this model does not include the programmable thumb button or the ability to add satellite shifters, it stands out by using two CR1632 batteries, helping to extend battery life.
Rear Derailleur
The rear derailleur is the center of operations for the whole groupset, by wireless communication with the shifters, direct connection to the internal battery and ANT+/Bluetooth connection for configuration via the E-TUBE app.
No more need to choose the correct cage length, the new 105 derailleur comes in a single cage length for use with cassettes up to 36T.
Builds
The Shimano 105 Di2 groupset is now featured on many mid-range bikes, gradually replacing the mechanical Ultegra groupsets that were previously common on these models. Bikes like the Madone SL 6, Émonda SL 6, and several others are now equipped with a 12-speed electronic drivetrain, delivering enhanced performance and smoother shifting.
