The revolutionary four-arm spider and Hollowglide chainring construction places the Shimano Dura-Ace 9100 compact crankset at a new industry standard with a remarkable 609g in weight. Its new geometry has been adapted to be compatible with race bike specific disc brake systems, allowing for larger clearance between the chainstay and chainring. The new design also provides a slight increase in rigidity and a reduction in weight over the 9000 series crankset, further improving performance. The Dura-Ace 9100 features a 24mm steel spindle axle, plus a choice between press-fit and threaded bottom brackets.
