Shimano 105 R7100 Di2 review - a brilliant groupset albeit expensive

105 Di2 makes Shimano's electronic shifting more accessible - but this isn't a 'groupset for the people' in the way the mechanical version always was

Cycling Weekly Verdict

It’s undeniably a good thing that Shimano released this groupset; more people will be able to enjoy the benefits of Di2 shifting, which continues to be a triumph. However, as a third tier groupset, cuts did have to be made and I believe they were made in the right place. The biggest problem which this groupset faces is the price, performance and practicality of its nearest rival: SRAM Rival.

Reasons to buy
  • +

    Shifting is what you’d expect from Di2

  • +

Reasons to avoid

    Expensive compared to SRAM Rival

Following the release of Dura-Ace and Ultegra at the back end of 2021, it maybe shouldn’t have been a surprise as to what was in store for 105. Shimano seemed to have waited a while to get this release out, especially since SRAM has been running their top three road groupsets in with both 12 speed and wireless for what feels like some time now. 

Not one to be rushed or be dictated to by SRAM, Shimano did the inevitable and gave 105 the digital treatment. It does share a lot of the same DNA as its bigger brothers as well as an inflated price over the mechanical counterpart - which is still readily available.
