Magene EXAR DB405 Ultra Carbon Wheelset

Magene EXAR DB405 Ultra Carbon Wheelset – Lightweight and Fast on Climbs

Magene EXAR DB405 Ultra – a premium carbon road bike wheelset designed for performance riding, hilly courses and racing. Its carefully balanced construction delivers a responsive feel during changes of pace, precise bike handling and efficient power transfer.

Key Features:

• Mixed rim depths: the 40 mm front rim improves handling and crosswind stability, while the 45 mm rear rim helps maintain speed for longer.
• HI-MOD carbon fibre: the stiff and lightweight rim construction enables faster acceleration and efficient transfer of pedalling power.
• Low wheelset weight: the pair weighs approximately 1,280 g, making the DB405 Ultra particularly suitable for climbing and courses with frequent changes of pace.
• VONOA carbon spokes: each spoke weighs just 2.8 g, while its aerodynamic profile helps reduce drag.
• Balanced spoke lacing: the 2:1 lacing pattern distributes spoke tension more evenly and increases lateral wheel stiffness.
• 36-tooth flat ratchet: the large engagement surface provides fast, precise engagement and consistent performance.
• Ceramic bearings: low rolling resistance allows the wheels to rotate smoothly and helps conserve energy at higher speeds.
• Wide rim profile: the 30 mm external and 23 mm internal widths are optimised for 28–32C road bike tyres.
• Optimised hub construction: precisely engineered flange geometry helps maintain similar spoke tension on both sides of the wheel.
• Tyre compatibility: the rims are compatible with tubeless and conventional clincher tyres.
• Optimised for TPU inner tubes: dynamic wheel balancing helps maintain stability at high speeds when using lightweight TPU tubes.
• Tested durability: the rims have passed the UCI 40 J impact test and meet the requirements for professional racing.
