Shimano Dura-Ace FC-R9200 Chainset

Shimano Dura-Ace FC-R9200 Chainset Featuring precision manufactured HollowTech II aluminium crank arms; the Shimano Dura-Ace FC-R9200 Chainset guarantees to transfer every watt generated into forward momentum; even when under the strain of a grand tour sprint. As their name would imply; these crank arms have a hollow construction that is meticulously internally chamfered to lower weight without sacrificing any strength. Partnering the crank arms is a hollow outer chainring that follows the same design targets; increased stiffness; improved strength and lower weight. In addition; both outer and inner chainrings feature unique tooth profiling to heighten shifting smoothness and speed. To complete the design; the 24mm diameter HollowTech II spindle mates perfectly with Hollowtech II bottom brackets (available separately) to provide increased pedalling efficiency under load.
