1.Lightweight High-Stiffness Carbon Rims Each carbon rim weighs just 330g, leveraging carbon fiber’s high specific strength to minimize rotational inertia—boosting acceleration and climbing efficiency. Its 35mm depth optimizes aerodynamics, while the 30mm external width works with tubeless tires (via low-pressure setup for better road grip). Ideal for both road and gravel riding, balancing speed and terrain adaptability. 2.Versatile Hub System Features 12×100/12×142mm thru-axles + center-lock design for superior axial stiffness and disc brake efficiency. Compatible with Shimano HG/MSR/N3W/XDR freehubs (covers entry to high-end groupsets) and 24-hole straight-pull construction, ensuring even spoke tension for enhanced overall rigidity and load stability. 3.Durable Practical Setup Tubeless-ready rims reduce puncture risks and rolling resistance. 4.3g steel straight-pull spokes combine light weight with high fatigue resistance, withstanding frequent riding impacts. Reliable for daily commuting and long-distance trips, extending wheel lifespan. 4.Customizable Aesthetics Offers tailored carbon fiber textures and paint finishes. Customize rim visuals to user preferences without compromising performance, elevating product differentiation.

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.

Carbon fiber rim: Full carbon construction delivers exceptional strength-to-weight ratio. Its 45mm height + 28mm outer/21mm inner width balances aerodynamics and tire compatibility, while offering custom finishes for personalization. Carbon fiber spokes: Straight-pull design, ultra-light at 3g each, leverages carbon’s rigidity for efficient power transfer, enhancing responsiveness. Aluminum hub: Complements carbon components with durable straight-pull architecture, center-lock disc brake, and versatile thru-axle (12x100/142mm) + freehub options (Shimano HG/MSR/N3W/XDR), ensuring broad compatibility. Personalized Customization (by Koibike factory): Personalize carbon finishes, paint, and spoke hole counts to match your style.

Ultra-light & High-strength: As low as 269g, made of 6061+7075 aluminum alloy composite, balancing lightness and rigidity. Efficient Structure: Straight-pull design enhances force transmission and wind resistance reduction; 12*100/12*142mm through-axle boosts stability with easy assembly/disassembly.
