Shimano Dura-Ace R9100 Double Chainset

The Shimano Dura-Ace R9100 Double 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.

Shimano has adapted the crankset 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.

The Double version offered here comes in numerous gear combinations to best suit each individual riders needs.

Please note: Bottom bracket is NOT included.


  • 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
  • Weight: 621g (53.39T)
