The MAGENE EXAR UltraDark DB508 Carbon Wheelset is a premium aerodynamic carbon wheelset engineered for road cyclists seeking maximum speed, efficiency and stability. Designed for modern disc brake road bikes, the DB508 features an advanced mixed rim profile with a 50 mm front rim and 58 mm rear rim, delivering the ideal balance of aerodynamic performance, crosswind stability and precise handling.

Constructed from HI-MOD carbon fiber, the UltraDark DB508 combines exceptional stiffness with an impressively low weight. The full carbon fiber spokes further reduce rotational mass while increasing lateral stiffness, resulting in quicker acceleration, more efficient power transfer and confident climbing performance.

The wide 30 mm external and 23 mm internal rim profile is optimized for modern road tyres. When paired with 28–32 mm tyres, the wheelset delivers improved aerodynamics, enhanced comfort and excellent grip, making it ideal for racing, fast group rides and long-distance endurance cycling. The tubeless-ready design also reduces rolling resistance and improves puncture protection.

Equipped with a 36T flat ratchet hub system, balanced 2:1 spoke lacing and a Standard Shimano 11-speed freehub, the DB508 UltraDark offers fast engagement, reliable performance and compatibility with Shimano 8–12 speed cassettes.

With a claimed weight of just 1390 g, the MAGENE EXAR UltraDark DB508 is an outstanding upgrade for riders looking for a lightweight, aerodynamic carbon wheelset that performs at the highest level.
