Magene EXAR DB508 UltraDark Carbon Wheels – Aerodynamics and High-Speed Performance

Magene EXAR DB508 UltraDark – a carbon road bike wheelset designed for fast training rides, racing, and routes where maintaining a high pace over long distances is important. The different front and rear rim depths help balance aerodynamic efficiency with confident handling: the bike remains stable on fast straights while staying easy to control through corners and in crosswinds. The updated hub design and carbon spokes deliver quick response during acceleration and efficient transfer of pedalling power.

Key features:

• Different rim depths: the front rim is 50 mm deep, while the rear rim measures 58 mm.
• Aerodynamic balance: the shallower front wheel provides greater control, while the deeper rear wheel helps maintain speed.
• Wheelset weight: the pair weighs approximately 1390 g; the manufacturer specifies a ±3% tolerance, excluding rim tape and valves.
• HI-MOD carbon fibre: the lightweight and stiff rim construction responds efficiently to acceleration.
• UltraDark finish: the dark finish and subtle logos give the wheels a clean, minimalist appearance.
• VONOA carbon spokes: each spoke weighs approximately 2.8 g and is around 30% lighter than a high-end steel spoke.
• 21 spokes per wheel: the 2:1 lacing pattern helps balance spoke tension and increase lateral stiffness.
• 36-tooth flat ratchet: provides precise engagement and stable power transfer.
• DT-type compatibility: the ratchet can be replaced with a compatible mechanism featuring a different tooth count.
• Wide rim profile: the external rim width is 30 mm, while the internal width is 23 mm.
• Recommended tyres: best suited to 28–32C tyres, although tyres from 25C can also be used.
• Tyre compatibility: hooked rims are compatible with both Tubeless and standard Clincher tyres.
• Maximum tyre pressure: up to 110 PSI with inner tubes and up to 100 PSI with tubeless tyres.
• Axle standard: 12 × 100 mm front and 12 × 142 mm rear.
• Freehub body: supplied with Shimano HG as standard, while SRAM XDR and Campagnolo N3W options are available separately.
• TPU tube-optimised balancing: helps maintain smooth and stable wheel rotation at high speeds.
• Package contents: includes tubeless rim tape and rim hole plugs.
