Light Bicycle WG55 – Maximum Speed & Stability for Gravel The WG55 (Wide-Gravel) carbon rim is built for riders who demand uncompromising aerodynamics, stability, and efficiency on gravel. With an ultra-wide 32mm internal width, it optimizes tire profiles for improved traction and rolling resistance while maintaining aerodynamic efficiency. At 55mm deep, the WG55 takes aero gains to the next level, reducing disruptive airflow and allowing air to pass smoothly across the tire-rim interface. Despite its depth, the rim remains stable in crosswinds, making it ideal for high-speed gravel racing, long adventure rides, and everything in between. Constructed from Toray T700 & T800 carbon fiber, the WG55 is available in Standard (460g) and Flyweight (400g) versions, catering to different rider needs. Designed with tubeless compatibility and a hybrid hook bead, it accommodates tire widths from 32C to 70C, offering superior versatility.
