The MAGENE EXAR Ultra DB405 Carbon Wheelset is a high-performance carbon wheelset designed for road cyclists who demand lightweight construction, excellent stiffness and efficient power transfer. Developed for modern disc brake road bikes, the DB405 combines advanced carbon technology, aerodynamic performance and low rotational weight to deliver outstanding acceleration and climbing performance.

The DB405 Ultra features a 40 mm front rim and 45 mm rear rim profile, creating an ideal balance between aerodynamic efficiency, handling precision and stability. The lower front and higher rear wheel design improves front-end control while maintaining strong rear-wheel momentum, making it an excellent choice for climbing, fast road riding and endurance cycling.

Built with HI-MOD carbon fiber rims and HI-MOD carbon fiber spokes, the EXAR Ultra DB405 achieves exceptional stiffness while reducing overall weight. The lightweight carbon spoke construction improves responsiveness, acceleration and power transmission compared with traditional spoke designs.

The wide 30 mm external rim width and 23 mm internal rim width are optimized for modern road tyres. Combined with 28–32 mm tyres, the wheelset provides improved comfort, tyre support, aerodynamic efficiency and confident handling. The tubeless-ready design allows riders to benefit from lower rolling resistance and improved puncture protection.

Equipped with a 36T flat ratchet hub system, ceramic bearings and a Standard Shimano 11-speed freehub, the DB405 ensures fast engagement, smooth operation and compatibility with Shimano 8–12 speed cassette systems.

The MAGENE EXAR Ultra DB405 is the perfect choice for road racers, climbers and performance-focused riders looking for a premium lightweight carbon wheelset with advanced technology and race-ready performance.
