Description

Shimano Dura Ace crank 2-FC-R9100

The easiest and most reliable Shimano crankset

The new Dura Ace crankset is characterized by a very high switching performance. The gearshifts are doing with high precision.
This is achieved by its broader HOLLOWTECH II-arm and a reinforced outer chainring to its unique asymmetrical Spider-construction with four arms. In terms of stiffness and lightness, the new R9100 cranks highest standards to meet.
