Shimano 105 Goes Semi-Wireless Di2 With The 7100 Series
The Shimano 105 FC-R7100 Crank is a super sturdy 2x12 HOLLOWTECH II style crankset intended to be paired with the new 12-speed 105 Di2 group.
The crank comes in both a 50x34t, and 52-36t configuration. Combined with the new 11-34 and 11-36t cassettes, it delivers a low, even sub 1:1 gear combination that can help riders take on steeper slopes, and better control their efforts.
The new Shimano 105 12 Speed Di2 groupset brings the benefits of semi-wireless electronic drivetrains to their workhorse line of components.
Pro level features are now available for every-day cyclists.
