All about this product
General
Thanks to being completely re-designed and improved from previous iterations the Shimano Dura-Ace R9100 Double Chainset offers one of the very best combinations 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.
Technical details
- Enhanced design saves 7g while maintaining rigidity
- Iconic 4-arm construction maintains high rigidity and reduces weight
- Optimised crank arm design strengthens key stress zones
- New chainring tooth profile is adapted for race bike specific disc brake systems
- Accommodates shorter chainstays (410mm) with 135mm OLD rear spacing
- Hollowglide chainring construction maintains smooth shifting whilst reducing weight and increasing stiffness
