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.
