* 25*26mm aerodynamic profile slices wind, enabling effortless speed. * Vacuum-integrated design eliminates air leaks and reduces rotational weight for responsive handling. * Disc brake compatibility ensures reliable stopping power in all conditions. * Fully customizable to perfectly match your bike’s specific specifications. * High-modulus carbon construction balances durability and agility, easing climbs and enhancing descents.

* The AM-MW28X36-29-CS-UL all-mountain wheelset is built around "all-terrain durability and a breakthrough in lightweighting." Its 29-inch hookless rim features a perfect ratio of 28mm depth, 36mm external width, and 30mm internal width. Its short rim depth enhances impact resistance on challenging terrain. * At an ultra-light 1326±30g, its combination of 2g/single KOIBIKE CS-T32 carbon fiber spokes and 330±5g MH-CS320T-Boost hubs achieves a weight reduction of over 12% compared to comparable all-mountain wheelsets (approximately 1500g). *Boost-spec thru-axles (15×100mm front / 12×148mm rear) and a center-lock disc brake system ensure precise braking and structural stability on bumpy terrain. The 24/24 hole straight-pull layout further enhances wheel rigidity, making it an ideal choice for all-mountain (AM) riding, demanding both lightweight climbing and aggressive descents.

1. Dual-Head Design and Full Compatibility T-Head (CS-T50): Increases the contact surface with the T-Head hub by over 35%. This reduces spoke-hub displacement and the risk of loosening in challenging conditions like hill descents and road sprints, making it particularly suitable for racing wheels requiring high stability. Around-Head (CS-A50): Featuring a curved round-head structure, it is compatible with most traditional standard hubs and can be installed without hub modification. It's ideal for upgrading entry-level wheels or performing routine maintenance, breaking the limitation of "specialized carbon spokes only fit specific hubs." Customized Length: Available in a range of 242-291mm, carbon spoke lengths can be precisely matched to rim diameter and hub flange size, for example, 700C road rims (260-280mm recommended), 27.5-inch mountain bike rims (260-280mm recommended), and 12.5-inch mountain bike rims (27.5-inch mountain bike rims). 270-291mm), to meet the wheel assembly requirements of different models.​ 2. Material Combination and Process Innovation Balanced Lightweight and Strength: The 3.5g weight of a single spoke is achieved through a "carbon fiber body + stainless steel threaded nut" combination. The carbon spokes are made of high-modulus carbon fiber (tensile modulus 230GPa), and the stainless steel nuts are made of 304 stainless steel (tensile strength ≥520MPa). This makes them easier to process than all-carbon fiber monolithic structures and avoids stress concentration issues at the carbon fiber-metal connection. Glueless Mechanical Locking Pultrusion: The carbon spokes and nuts are secured together through a mechanical interlocking mechanism, eliminating the need for glue. This eliminates the risk of long-term loosening due to glue aging and simplifies installation, requiring only a standard spoke wrench for complete tightening. The precision of the process ensures an overall tensile strength of 3 kilonewtons (approximately 306 kgf), far exceeding that of traditional steel spokes (approximately 180 kgf). Spoke tension is maintained at a stable 120-130 kgf, and the tension decay rate is ≤5% after long-term use.​ 3. Detailed Design and Durability Flat Carbon Wire Rope Construction: 5.0 ± 0.1mm wide and 0.83 ± 0.1mm thick flat carbon wire ropes reduce wind resistance by 18% compared to round carbon wire ropes (tested at 40 km/h). They also increase the flexural strength of the wire ropes. Under lateral impacts (such as rock scraping during mountain biking), deformation is ≤ 0.2mm, and there is no permanent deformation after loosening. Anodized Black Stainless Steel Nuts: 304 stainless steel nuts are anodized and withstand salt spray tests for over 48 hours, making them resistant to rain, humidity, and other harsh environments. They avoid rusting associated with traditional galvanized nuts and extend maintenance intervals by 60% compared to conventional nuts. Glueless Nipples: Glueless nipples provide dual stability with the mechanical locking mechanism of the spokes. The nipples fit the rim holes with a tolerance of ≤ 0.05mm, reducing unwanted squeaking and improving the overall smoothness of the wheel.

This carbon bottle cage is designed with "extreme lightweight and easy installation" in mind. At 10.9g each, it's 15%-20% lighter than similar carbon bottle cages. Leveraging the high modulus of Toray's T700-grade carbon fiber, it maintains a clamping strength exceeding 200N while reducing weight. Its innovative upper and lower double-hooked design, with the upper hook 2mm deeper and the lower hook 1.5mm wider, creates a "hugging and lifting" dual-locking structure, ensuring the bottle remains stable even on bumpy mountain roads or high-speed highway rides. Mounting to the frame requires only two screws, taking less than a minute. It fits standard bottle cage mounting holes on most road, mountain, and commuter bikes, offering a balance of performance and practicality, making it an ideal choice for those seeking lightweight cycling.

*The WR50X28TL-SS-UL wave rim wheelset features "all-scenario adaptability + innovative wave rim construction." Its 50mm waved rim cross-section and 28mm width combine to overcome the traditional dilemma between aerodynamic performance and rough terrain cushioning. The wave crest streamlined design reduces drag by 12% compared to a straight-sided rim of the same height at 15° crosswinds, while the wave valley structure absorbs the impact of gravel road bumps, accommodating both road cruising and light off-roading. *A lightweight weight of 1295±30g and Sapim CX-RAY steel straight-pull spokes ensure rigidity within the 120kg rider weight limit while reducing rotational inertia. *Suitable for both tubeless and clincher tires, with a 28-50C tire range and 50-80PSI tire pressure adjustment, it adapts to a variety of riding scenarios, from paved roads to gravel roads. *The KOIBIKE RH-SS260-DB hub features a center lock design compatible with various freehub bodies. Its black exterior combines performance with visual recognition, making it a versatile choice for all-terrain riding.
