Shimano 105 FC-R7100 Hollowtech II 2x12-speed road bike crankset

To celebrate the 40th anniversary of its 105 groupset, Shimano has decided to make a big splash by switching its third groupset to electronic mode. Within this modern groupset, designed for the general public, the Shimano 105 Di2 FC-R7100 Hollowtech II crankset promises faster and more precise gear changes than the mechanical version. Available with two gear ratios, namely 50-34 or 52-36, this crankset ensures smooth and progressive shifting with an 11-34 or 11-36 12-speed cassette. With this versatile gear ratio, you’ll be able to ride fast on the flat and tackle all climbs with ease.

Thanks to this new Shimano 105 Di2 FC-R7100 crankset, power transfer will be as efficient as possible with the Hollowtech II structure. As well as reducing weight, this design ensures the crankset is rigid, allowing you to generate more power and thus improve your performance on all terrains. Available in several crank lengths, there’s something for everyone. In short, all cyclists will be able to make the most of this new Shimano 105 Di2 12-speed groupset.
