The GW42-52X36TL-CS-UL gravel road wheelset features a core design featuring "different front and rear rim depths + wide tire compatibility." The front wheel features a low 42mm profile for enhanced handling, while the rear wheel features a high 52mm profile for enhanced aerodynamics and power transfer. Its 30mm internal width and black marble-patterned exterior ensure both maneuverability and visual recognition when switching between gravel and paved roads. Weighing in at a lightweight 1157±30g (8% lighter than similar gravel wheels), paired with 2g/strip CS-T32 carbon straight-pull spokes and 227±5g KOIBIKE RH-CS220 straight-pull hubs, the wheels deliver a 15% improvement in transmission efficiency over steel-spoke wheelsets. A center-lock disc brake system and 12×100/12×142mm thru-axles ensure stable braking on bumpy gravel surfaces. Compatible with Shimano HG/MSR, Campagnolo N3W, and SRAM XDR freehubs (with gold accents), the wheelset offers a versatile and efficient performance solution for gravel road riding.

This quick-release assembly features a "scenario-specific adaptability + high-strength and durable design." The front quick-release is 100mm long (compatible with a 100mm fork clearance), while the rear quick-release covers various lengths: 130mm (road), 135mm, 142mm, and 148mm (Mountain Boost), precisely adapting to the rear fork clearance requirements of different bikes. A weight distribution of 440±15g for the front wheel and 490±15g for the rear wheel ensures lightweight handling while also enhancing structural strength through the added weight of the rear wheel. The rear quick-release is constructed of thickened stainless steel, offering 25% greater torque capacity than standard quick-releases. A spring-loaded design ensures stable locking in both bumpy mountain terrain and high-speed highway cruising, preventing wheel drift. This is a versatile and secure quick-release solution.

*The DW35X28TL-CS-UL wheelset features a "35mm low-profile aerodynamic + all-around adaptability" design. Its optimal ratio of 28mm external width to 21mm internal width maintains the nimble handling of a low-profile wheel while optimizing aerodynamics through its U-shaped cross-section. At 15° crosswind, drag is reduced by 12% compared to a straight-sided wheel of the same height. *With an ultra-light total weight of 1039 ± 30 grams (rim + hub + spokes + nipples), paired with 3g/single CS-R38 carbon straight-pull spokes and 279 ± 5g KOIBIKE RH-CS275 hubs, the wheelset's rotational inertia is reduced by 25% compared to a comparable steel-spoked wheel, resulting in a more responsive acceleration. Compatible with tire pressures from 50-80 PSI and 25-40C tires, it features a 12x100/12x142mm thru-axle and center-lock disc brake system. *Compatible with Shimano HG/MSR, Campagnolo N3W, and SRAM XDR cassettes. Its uniform black design combines performance and style, making it a versatile choice for road racing, gravel riding, and long-distance endurance racing.

*The RH-CS275T-DB road hub is designed with "lightweight and high efficiency for road racing + full carbon spoke compatibility." It reduces wheel rotational inertia by 22% compared to similar hubs during both flat cruising and climbing sprints. *An ultra-light total weight of 279 ± 15g delivers a perfect balance of lightweight and rigidity. *Supports seamless integration with T-head and round-head carbon spokes, offering both steel ball bearings (default, workhorse) and ceramic bearings (performance upgrade). Compatible with Shimano HG/MSR, Campagnolo N3W, and SRAM XDR multi-freehubs, and customizable laser engraving is also available. *The disc brake system ensures stable braking in the rain, creating a carbon spoke wheel core that combines "racing-grade drivetrain with personalized fit" for road cycling.

*This extended-length MTB (Boost) hub features "Boost-grade adaptability and multi-freezer compatibility." Its 15x100mm front and 12x148mm rear thru-axle designs ensure precise power transmission and torsional resistance in demanding off-road conditions, such as rocky slopes and continuous spurs. *With a total weight of 306±15g and a 28/28 hole straight-pull layout, it features a steel spoke-compatible design. A reinforced bore treatment minimizes spoke tension tolerance to within 4%, ensuring both strength and durability. *Made of a dual-material aluminum alloy 6061 + AL7075, it's compatible with Shimano HG/MS and SRAM XD multi-freezer bodies and disc brake systems, creating a core component for MTB that combines "toughness, compatibility, and efficient transmission" for use with disc brakes.

The XC-W25X35HL-29ER-UL off-road wave rims are based on a 29-inch wheel diameter. Their 25mm low-profile wave profile and 35mm external width overcome the off-road dilemma of "low rim flexibility and wide tire support." The short-pitch, wave-shaped design improves torsional resistance by 14% over straight-sided rims of the same height in bumpy conditions. The 35mm external width is compatible with wide off-road tires from 2.2-2.7 inches. At an ultra-lightweight 320 ± 15 grams, they're approximately 12% lighter than similar hooked off-road rims. The low tire pressure range of 18-30 is ideal for navigating soft muddy terrain, gravel slopes, and other terrain. The straight-edge, hookless rim grooves simplify wide tire installation. The UD/marble finish, paired with a full matte and smoked black finish, makes it instantly recognizable for off-road use. The innovative wave-shaped structure delivers dynamic cushioning, ensuring stability even under the 120kg rider weight limit, providing both flexibility and strength for XC off-road riding.

The W60X28TL-UL wave rims, built around a 29-inch wheel diameter, combine a 60mm high-wave profile with a 32mm external width, breaking the traditional dilemma of tall rims for aerodynamics and wide tire compatibility. The streamlined design with corrugated peaks and valleys reduces drag by 10% compared to a straight-sided rim of the same height at 18° crosswinds. The 32mm external width is compatible with tires ranging from 25-47cm. At an ultra-light 490±15g, the rims lack spacers in the spoke holes, saving approximately 8% compared to rims of the same specification with bushings. A high tire pressure range of 36-100cm is suitable for mixed paved/gravel terrain. Hooked rim grooves enhance tire retention. The white rims, available in a variety of finishes, including matte and smoked black, are visually recognizable. The innovative wave structure's stress-distributing design ensures stable performance even at a rider weight limit of 120kg, providing the dual benefits of aerodynamics and durability for crossover riders.

The W45X32TL-UL Wave rims, based on a 29-inch wheel diameter, feature a perfect ratio of 45mm height and 32mm outer width. Their unique wave-shaped rim design achieves a breakthrough in both lightweight and torsional rigidity. At an ultra-light 380±15g, they're approximately 15% lighter than traditional straight-sided rims of the same specification. With a tire pressure range of 18-30, they accommodate tires 2.2-2.7 inches wide, and a rider weight limit of 120kg, they meet most riding needs.
