SHIMANO DURA ACE FC-R9100 CRANKSET

The Shimano Dura Ace FC-R9100 11-speed crankset has the same 4-arm design with a uniform 110 mm bolt circle diameter as its predecessor, but it has lost weight again. The hollow forged Hollowtech crank arm now weighs seven grams less, which increases the performance even more. The hollow large chainring also benefits from the weight saving. Since the Dura Ace also moves with the times, the FC-R9100 can be easily used on racing bikes with disc brakes. What has remained, of course, is the unique, surely already iconic Dura Ace aesthetics and the Hollowtech II construction for the best stability values. The crank arms are still made of aluminium, carbon is also used for the chainrings. There are five different double shades and six arm lengths available,
