Aerodynamics

The air resistance is accountable for approximately 90% of resistance forces during a handbike ride. Less air resistance gives you a significant advantage in the race. That’s why, aerodynamics is what we paid a special attention to, when designing our bike. The underside of our frame is shaped as an airfoil. Such shape, together with a smooth broadsides without angles, organises an airflow between the frame and a road surface. That minimizes turbulences, and therefore minimizes the air resistance.

• Disc Brake

  • Gives smooth braking, and thus full control over the braking force – needed especially at high speeds
  • Its efficiency decreases only slightly while driving, especially in the case of carbon rims, which are sensitive to the temperature rise during braking with calliper brakes
  • Unlike other types of brakes, they are practically insensitive to weather conditions

• Thru-Axle

  • Increases the stiffness of the fork-wheel system
  • Allows for more precise positioning of the wheel (especially important when mounting a disc brake)
  • Reduces the risk of the wheel disconnecting when using a disc brake

• Continuously Adjustable Crankset Height

  • The distance between the axis of support and the seat is smoothly adjustable in the range of +/- 2cm from the distance requested in the inquiry form.
