The WR50X28TL-SS-SL wave rim wheelset is a high-performance wheelset developed specifically for all-terrain riding. Its core breakthrough lies in the synergistic design of a 50mm wave rim structure and dual-tire compatibility. The rims are constructed from Toray T800-grade carbon fiber, using a variable curvature hot pressing process to create a wavy cross-section. The peaks of the waves optimize aerodynamics, while the troughs act as stress buffers. This ensures the aerodynamic advantages of a 50mm-tall rim while also improving impact resistance on challenging terrain. The 28mm width is compatible with 28-50C tires and supports both tubeless and clincher setups, allowing you to switch between different riding styles without changing rims. The tire pressure range is 50-80 PSI, with lower pressures ideal for gravel and higher pressures for road racing.
Equipped with a KOIBIKE RH-SS260-DB aluminum alloy straight-pull hub, a 24-24 hole straight-pull layout, and Sapim CX-RAY steel spokes, the wheelset boasts a single-spoke tensile strength of 480N, increasing overall stiffness by 18% compared to a similarly sized wave rim wheel. The 269±5g hub weight and 4.3g steel spokes combine to achieve a balance between lightweight (1295±30g) and durability. The hubs support interchangeable freehubs for Shimano HG/MSR, Campagnolo N3W, and SRAM XDR. The black rims contrast visually with the gold freehubs. Spare spokes, rim spacers, and valves are included, providing a complete "install-and-use" solution with long-term maintenance, suitable for diverse riding scenarios, including road, gravel, and light off-road.
Wave rim construction for all riding scenarios:
The 50mm waved rim utilizes an innovative "aerodynamic crest + trough cushioning" design. When cruising on the road, the wave crests streamline airflow and reduce drag, resulting in a 12% improvement in aerodynamic efficiency compared to straight-edged rims. When entering gravel, the troughs deform slightly by 1.5mm, absorbing bumps and shock, reducing vibration by 25%. The T800 carbon fiber boasts a shear strength of 5.2GPa. In a 1-meter rock impact test, the rim deflected ≤0.08mm, ensuring a balanced aerodynamic and impact-resistant ride.
Dual-Tire + Wide Tire Compatibility:
The 28mm rim width is compatible with 28-50cm tires. In tubeless mode, the inner rim seal grooves securely align with the tubeless tire bead, maintaining a 24-hour air loss of ≤1.0psi. In clincher mode, it's compatible with traditional inner tubes without any additional modification. Narrow 28cm tires are ideal for road racing, while wide 50cm tires are suitable for gravel roads, allowing users to flexibly switch between configurations without changing wheels.
High Rigidity and Lightweight Balance:
The 1295±30g total weight is achieved through "precise material distribution"—four layers of carbon fiber at the rim's crests enhance aerodynamic stiffness, while two layers at the troughs provide cushioning flexibility. This makes it 15% lighter than conventional steel spokes while also increasing tension by 20%. The 24-24 hole straight-pull layout improves power transmission efficiency by 10% compared to cross-spokes, providing more direct acceleration on hills.
Multiple freehub body compatibility and easy maintenance:
The KOIBIKE RH-SS260-DB hub supports quick-change freehubs for Shimano HG/MSR, Campagnolo N3W, and SRAM XDR. The included spare spokes, rim spacers, and valves alleviate the hassle of purchasing spare parts for future maintenance, extending the life of the wheelset.
Precise braking with center lock:
The hub utilizes a center lock design, achieving a concentricity error of ≤0.02mm with the disc brake rotor, ensuring zero rotor runout during braking and a brake response delay of ≤0.2 seconds. Combined with the heat dissipation texture of the black rim, the rim temperature is reduced by 10°C during continuous downhill braking, preventing brake fade caused by high temperatures. This makes it ideal for long-distance mountain and road cycling.
Application areas for the WR50X28TL-SS-UL carbon spoke wheel:
Road and Gravel Crossover:
28-50mm wide tire compatibility and a beaded rim design allow for high-speed cruising on paved roads with narrow 28mm tires, while also allowing for smooth traversal on gravel roads with wide 50mm tires. This makes it ideal for weekend mixed-use road and light off-road riding, eliminating the need to carry multiple wheels and increasing mobility.
Long-Distance Endurance Cycling:
The aerodynamic advantages of 50mm beaded rims reduce the physical strain of long-distance cruising. The high durability of Sapim CX-RAY steel spokes reduces the risk of failure. A 50-80 PSI tire pressure adjustment allows for optimized riding feel based on road conditions—80 PSI for improved efficiency on flat roads and 50 PSI for enhanced cushioning on mountain roads. This makes it suitable for long-distance endurance rides of over 200 kilometers.
Entry-Level Competition Training:
1295±30g lightweight and highly rigid, it meets the training needs of entry-level road races and gravel events. The center-lock brake provides precision, allowing riders to adapt to high-intensity braking situations. Multi-freezer body compatibility allows for adaptability to various training shifting systems, reducing equipment replacement costs, making it ideal for advanced riders in both daily training and competition preparation.
Personalized Commuter Modification:
The visual combination of black rims and gold freehubs creates a sporty and recognizable look, compatible with most commuter bikes. The 28mm width is compatible with 32C puncture-resistant tires, balancing commuting efficiency and road adaptability. Tubeless mode reduces punctures and reduces maintenance for daily commutes, making it an ideal choice for commuters seeking both individuality and practicality.
Bulk Purchase for Cycling Clubs:
Dual tire compatibility, multi-freezer body compatibility, and a complete set of bonus accessories make it ideal for clubs purchasing in bulk. Different members can choose tires and shifting systems based on their riding habits. The unified black appearance facilitates club image management. Spare parts reduce maintenance coordination costs and enhance the group riding experience.
