TI-3.7-Flat Spokes

TI-3.7-Flat Spokes | Lightweight High-Performance Wheel Spokes

 

Two months ago, we set up a dedicated team specializing in titanium alloy spoke manufacturing. Following two months of market research and repeated design iterations by our elite team, this 3.7g titanium alloy spoke is officially launched. The colours listed below are available for customisation

Titanium boasts a density of 4.44 g/cm³, only 56% that of steel spokes. Spokes of identical specifications weigh less, reducing the wheel’s rotating mass for snappier acceleration and handling response.

Manufactured from aluminium-vanadium titanium alloy, these spokes deliver a tensile strength of 1126 MPa and an ultimate load of 360 kgf, with a recommended lacing tension range of 80–140 kgf. Every spoke undergoes high-temperature refining, stress relief, alongside tensile, hardness and fatigue testing. It achieves up to 19,366 fatigue cycles, offering outstanding fatigue resistance and corrosion resistance. The wheels resist deformation over long-distance riding for consistent stability.

Aerodynamic Streamlined Bladed Profile

Built with a streamlined bladed cross-section (2.3 mm width × 1.5 mm thickness), they cut wind resistance by 30%–50% compared with conventional round spokes and minimise turbulent airflow. Engineered for slim lightweight geometry without compromising strength. A 270 mm spoke weighs merely 3.7 g. The reduced airflow contact area lowers drag, balancing lightweight construction and aerodynamic efficiency.

Precision Grinding Machining

Titanium is notoriously difficult to machine. Custom tooling enables precision processing to guarantee uniformly smooth spoke surfaces. Surface imperfections that trigger turbulence are eliminated, sustaining steady aerodynamic performance.

Flared Radius Transition Spoke Head

A rounded transition is adopted at the joint between the head and shaft — a common site for fatigue cracks: • Distributes stress to extend fatigue life and lower fracture risks • Transmits load evenly to avoid gouging or damaging hub holes • Enables smooth insertion and self-alignment during assembly, facilitating balanced spoke tension and minimising pull-out hazards
