Shimano Dura-Ace 9100 Chainset
The Shimano Dura-Ace R9100 Compact Chainset has been completely re-designed to offer the very best combination of light weight and stiffness. It features Shimano's iconic 4-arm hollow spider that is made from hollow-forged aluminium.
Although the crank arms and spider arms are noticeably bigger, which increases stiffness, the overall weight has dropped by 7g over the previous edition of Dura-Ace.
The crankset has been adapted to work with disc brake road bikes that generally have 135mm rear hub spacing and shorter chainstays without the need to increase Q-factor thanks to its wider chainring spacing.
