The Shimano Dura-Ace FC-R9100 Crankset has a wider arm than the previous 9000 series crank, but this top-level component still manages to shave weight without reducing stiffness. Hollowglide chainrings and a Hollowtech II crank construction make this superb feat possible, and it’s ready for today’s modern race geometries with a re-positioned inner chainring to improve performance with 135 mm rear-spacing frames and short chainstays.

Available in multiple crank lengths and gearing options. Compatible with Shimano BB-R9100 and BB-R9100-PB bottom brackets.
