Toray Carbon: Lightweight & Rigidity Redefined Japanese Toray carbon rims and spokes deliver "featherlight strength" — just 1235g per pair (min.), over 30% lighter than alloy equivalents for effortless climbs. Carbon’s high modulus boosts torsional rigidity by 40%, ensuring precise high-speed cornering with zero power loss. Tubeless + Carbon Spokes: Beyond Traditional Performance Tubeless design cuts rolling resistance by 15% (adding 10km range) and slashes punctures by 60% via anti-puncture coating, ideal for rough terrain. 3g carbon straight-pull spokes (70% lighter than steel) amplify power transfer by 25%, turning every pedal stroke into pure forward momentum. Aerodynamic Geometry: Master of All Speeds Front 55mm/ rear 62mm height: Agile low-speed handling meets 20% less wind resistance at 30km+/h for easy high-speed cruising. 28mm width (with tubeless) adds 12% more grip, balancing aerodynamics and control. Disc Brake Excellence: Stopping Power in All Weathers Center-lock disc brakes paired with aluminum straight-pull hubs react 0.3s faster than rim brakes — cutting 40km/h wet braking distance by 2m. Hubs reduce rotation resistance by 18% for longer glides and effortless rides. Custom Style + Precision Details Full-color custom paint (gradients, laser patterns) makes your ride one-of-a-kind. 0.3g aluminum spoke nipples blend easy maintenance with extreme lightness, refining both form and function.

The KOIBIKE D50X30TL/HL-UL is a high-performance road wheelset. Its 50mm rim depth and 30mm external width ensure excellent aerodynamic efficiency. Its 24mm internal width is compatible with 28–50c tires, adapting to a wide range of riding conditions. The straight-rim version is designed for tubeless tyres and offers excellent sealing, while the hook-rim version is compatible with both tubeless and clincher tyres, offering greater flexibility. Each rim weighs a mere 400g ± 15g. Made from Japanese Toray T700 to T1100 carbon fiber, the UD paint treatment not only highlights the carbon fiber texture but also provides scratch and sun protection.
