Its black exterior combines performance with visual recognition, making it a versatile choice for all-terrain riding.

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 4.4±5g for the front wheel and 4.9±5g 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 G52X36TL-UL gravel rims, built on a 29-inch wheel diameter, feature a 52mm depth and 36mm outer width, achieving breakthroughs in both aerodynamics and stability for gravel riding. At an ultra-lightweight 455 ± 15 grams, they're approximately 12% lighter than similar gravel rims, significantly reducing rider fatigue. A wide tire pressure range of 30-60PSI accommodates tires from 35-55C , with a rider weight limit of 125kg. Available in a variety of finishes, including marble, they offer a new option for gravel riding that combines performance and style.

These 25mm high, 100mm external width, and 95mm internal width snow rims are a true "buoyancy weapon" for snow riding. The extra-wide internal width is suitable for giant snow tires, increasing the contact area by over 60% compared to standard rims, making them easy to navigate deep snow. The 25mm low profile design enhances handling flexibility, and the UD paint finish remains scratch-resistant and abrasion-resistant even in temperatures as cold as -30°C.
