  • 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 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.

    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:

    • 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: 609g (50.34T)

    A 2 year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).
