Developed for aerodynamic efficiency

The 58 mm deep and 30 mm wide rim has been specifically developed around modern road tyre combinations. With 25 and 28 mm tyres, the tyre-to-rim transition remains particularly clean, helping to maintain efficient airflow around the wheel.

The integrated AERO GROOVES are another distinctive feature of the MARK4. They are designed to influence airflow around the spokes in a controlled way and help reduce turbulence.

During development, the MARK4 was optimised using CFD simulations and subsequently tested in the wind tunnel and under real-world riding conditions. At realistic yaw angles of 10° to 12.5°, wind tunnel testing showed a reduction in power demand of more than 3 watts compared with conventional 45 and 60 mm spoked wheels.

Austrian monocoque construction

Unlike conventional spoked wheels, the MARK4 is produced as a complete carbon monocoque. Rim, spokes and hub are developed as one integrated structure.

This construction delivers the direct and precise handling that is particularly noticeable at higher speeds and in demanding racing conditions.

With a wheelset weight from 1,530 g, tyre compatibility from 25 to 42 mm and a maximum combined weight of 120 kg, the MARK4 offers the versatility required for a wide range of road setups.

Built for riders who expect more
