Bike Spoke

1.Ultra-light & High-efficiency: Only 3g per spoke, greatly reducing wheel inertia for lighter riding and faster speed 2.Tough & Durable: Carbon fiber body for high tensile strength, stainless steel threads/caps for corrosion resistance, and glue-free mechanical locking to prevent loosening 3.Precise & Uniform: Pultrusion process ensures consistent specs (e.g., 3.8mm width) and stable quality in bulk production 4.Practical & Aesthetic: Matte finish for scratch resistance and easy cleaning; round-head/T-head options fit different wheel hubs, balancing appearance and compatibility

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.
