Shimano Dura-Ace R9100 Compact 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 aluminum.

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.

The Compact version offered here features a 50.34T chainring profile to offer an excellent rider tuned gear combination for varied conditions from flats to high mountains.

Please note: bottom bracket is NOT included.

Features:

  • The 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
