The new Shimano 105 Di2 R7100 groupset is in line with the recent trend of fully electronic groupsets at a more affordable price than ever before. 

The new Shimano 105 Di2 R7100 groupset is Shimano’s first foray into offering an affordable electronic groupset, competing directly with the Sram Rival AXS drivetrain. The design of the R7100 is mostly taken from the higher-end Ultegra R8100 and Dura-Ace R9200, both having been updated to 12 speed drivetrains in the last few years.


The new shifters have the same ergonomics as the more expensive counterparts, with a few functions removed; the top button is not part of the shifter, nor is the extra port for connecting satellite shifters. That said, these missing features are balanced by the fact that they can accept two (rather than one) coin cell batteries for longer 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. 


The new Shimano 105 Di2 groupset will feature on mid-range builds, which would have previously been built with an Ultegra mechanical groupset. Models such as the Madone SL 6 2023, Émonda SL 6 2023 and others will now include an electronic groupset.
