Shimano Dura-Ace 11 Speed Road Double Chainset

Shimano Dura-Ace R9100 11 Speed Road Double Chainset

The Shimano Dura-Ace R9100 11 Speed Road Double Chainset boasts Shimano's well-known 4-arm hollow spider that is constructed from hollow-forged aluminium. This chainset has been completely redesigned to ensure it boasts the best combination of lightweight and rigid construction. 

The chainset has been adapted by Shimano to work with disc brake road bikes that have a 135mm rear hub spacing and shorter chainstays without the need to increase Q-factor thanks to its wider chainring spacing. Although the crank arms and spider arms are bigger, this increases overall stiffness, and the chainset has dropped 7g of weight since its previous edition.

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

Please note: A bottom bracket is NOT included.

Features:

• 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)
