Description
Exar DB508 UltraDark Series Carbon Fiber Wheelset
The Exar DB508 UltraDark Series Carbon Fiber Wheelset is a cutting-edge disc brake wheelset released in 2024. This high-performance wheelset boasts a unique design with a lower front and higher rear rim height, offering riders an optimal balance of speed and stability.
Sleek Night Black Design
The DB508 UltraDark features a striking night black paint coating with dark logos. This classy and trendy design complements a wide range of bike frames, giving your ride a sense of speed and style.
Lightweight Performance
Crafted with HI-MOD carbon fiber, the DB508 UltraDark wheelset achieves a significant weight reduction while maintaining exceptional stiffness. At just 1390g (including a ±3% tolerance on weight, without rim tape and valve), this wheelset enhances your climbing and acceleration capabilities.
Aerodynamic Excellence
The DB508 UltraDark combines a 50mm front wheel with a 58mm rear wheel. This configuration provides excellent aerodynamic performance and crosswind resistance while maintaining high inertia in the rear and superior controllability in the front. You’ll experience improved stability and pedaling efficiency, along with easier handling during turns and emergency maneuvers.
Advanced Hub Technology
The flat engagement ratchet system ensures stable performance across all speeds. Riders have the flexibility to replace the original ratchet with other DT ratchets of varying tooth counts for customized responsiveness. The rotating sound is more even thanks to the flat wire spring design.
Ultra-Stiff Carbon Fiber Spokes
Featuring VONOA’s carbon fiber spokes, each weighing only 2.8g, the DB508 UltraDark achieves remarkable stiffness. These spokes are 30% lighter than top-level steel spokes and can withstand 30% more tensile force, resulting in higher driving efficiency and reduced strength loss during power transmission.
Wide Rim for Comfort and Aerodynamics
With a 30mm external rim width and 23mm internal rim width, the DB508 UltraDark is optimized for 28-32c tyres. This design creates a flatter aerodynamic surface and enhances cycling comfort, ensuring optimal performance in various wind conditions.
Meticulously Engineered Hub
The hub design incorporates several advanced features:
- Improved flange diameter for better driving stiffness and endurance
- Smooth edging on bearing surfaces to reduce losses
- Scientific WR size of 18.2mm for balanced spoke tension
- 2:1 balanced spoke pattern for optimal tension distribution
Additional Features
- Disc brake compatibility
- Tubeless-ready design (comes with tubeless rim tape and plugs)
- Clincher tyre compatibility
- Dynamic balance optimized for TPU inner tubes
The Exar DB508 UltraDark Series Carbon Fiber Wheelset represents the pinnacle of cycling technology, offering riders a perfect blend of speed, stability, and style for their high-performance cycling needs.
