  • Shimano Dura-Ace R9100 Compact 11 Speed Chainset

    The Dura-Ace R9100 chainset is the highest level of cranks produced within the Shimano road product range. Designed to be light weight and stiff, this compact chainset comes with a 50-34t chainring setup ensuring you have a wide range ratio for climbing and descending.

    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 chainset has been adapted to work with disc brake road bikes that generally have 135mm rear hub spacing and shorter chainstay 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.
