Ride smooth. Be fast.<\/strong><\/p>\n

With the MARK4, XeNTiS combines aerodynamic efficiency, monocoque technology and precision manufacturing to create a distinctive carbon wheelset for demanding riders.<\/p>\n

Developed for road cycling, triathlon and racing, the MARK4 focuses on speed, efficiency and precise handling. Its distinctive 5-spoke monocoque construction<\/strong> is manufactured in Austria and forms the foundation for the wheel’s combination of aerodynamics, stiffness and direct power transfer.<\/p>\n

Developed for aerodynamic efficiency<\/h3>\n

The 58 mm deep and 30 mm wide rim<\/strong> 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.<\/p>\n

The integrated AERO GROOVES<\/strong> are another distinctive feature of the MARK4. They are designed to influence airflow around the spokes in a controlled way and help reduce turbulence.<\/p>\n

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\u00b0 to 12.5\u00b0, wind tunnel testing showed a reduction in power demand of more than 3 watts compared with conventional 45 and 60 mm spoked wheels.<\/p>\n

Austrian monocoque construction<\/h3>\n

Unlike conventional spoked wheels, the MARK4 is produced as a complete carbon monocoque<\/strong>. Rim, spokes and hub are developed as one integrated structure.<\/p>\n

This construction delivers the direct and precise handling that is particularly noticeable at higher speeds and in demanding racing conditions.<\/p>\n

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

Built for riders who expect more<\/h3>\n

From everyday training and fast road rides to triathlon and racing, the MARK4 combines XeNTiS monocoque technology with a concept focused on aerodynamic efficiency.<\/p>\n

Developed. Calculated. Tested. Handcrafted in Austria.<\/strong><\/p>\n
