The Magene EXAR UltraDark DB405 Carbon Wheelset 40/45mm (Disc Brake) is engineered for performance-focused road cyclists who want a refined combination of low weight, aerodynamic efficiency, stiffness and responsive handling. Designed specifically for modern disc brake road bikes, this wheelset uses a differentiated rim-depth setup with a 40mm front rim and 45mm rear rim to balance steering control, aerodynamic stability and speed.
The shallower front rim helps maintain confident handling and steering precision, while the deeper rear rim supports improved aerodynamic efficiency and speed retention. This 40/45mm combination makes the DB405 a versatile option for climbing, fast road rides, racing, endurance events and rolling terrain.
At the core of the wheelset is HI-MOD carbon fiber construction, selected to reduce weight while maintaining excellent structural stiffness. Lower rotating weight contributes to quicker acceleration and a more responsive feel during climbs, attacks and repeated changes in pace. At the same time, the stiff carbon structure helps transfer pedaling input efficiently, giving the bike a direct and performance-oriented character.
The upgraded hub and spoke system is designed to provide faster and more stable response. This helps improve power transfer and overall wheel stability, especially during hard accelerations and high-speed riding. The combination of refined rim construction, responsive hubs and optimized spoke performance makes the DB405 suitable for riders looking to upgrade from heavier alloy or entry-level carbon wheels.
A distinctive Night Black coating with dark graphics gives the UltraDark series a clean and premium appearance. The understated black-on-black aesthetic works well with a wide variety of bike frame colors and creates a modern race-inspired look without excessive branding.
Because the DB405 is developed specifically for disc brake applications, the carbon rim can be optimized around aerodynamic and structural performance without requiring a traditional braking surface. This makes it well suited to contemporary road bikes built around disc brake technology.
