Product details:
The Dura Ace 9100 crankset has been given a new look and has become even more striking in its appearance. The crank wasn't just designed to look good however. The powertransfer has been improved because of the wider asymmetric crankarm, but without a penalty to weight. Thinwalled, forged aluminium cranks with an optimised chainring design. Thanks to the innovative 4-point mounting system, it's possible to mount any available chainring size to the cranks. This allows you to easily convert a double to a compact, and vice versa.
