  • Wide stance seat stays: With the stays set further from the wheel, airflow isn’t disrupted by the reversing flow coming off the tyre
  • Deep airfoil seat tube: The rear wheel is tucked in tight to a cut-out in the deep-section airfoil seat tube for smoother airflow
  • Optimised tyre size: The ONE and its Black Inc wheels are both designed around tyres 25-28mm for lower rolling resistance and optimum ride quality
  • Seatpost options: The ONE is offered with a choice of Zero and Offset seatposts with fittings for carbon (7x9mm) or metal (7x7mm) saddle rails
  • Power drivetrain: The continuous fibre construction of the down tube and chain stays gives the ONE unrivalled stiffness under power
  • Brake options: The ONE continues to be offered in both direct-mount rim brake and flat-mount disc brake options
