Spoke thread rolling machine Cyclo CYC-07836 for 12G, 13G, 14G spokes

The Cyclo CYC-07836 spoke thread rolling machine is a mechanical tool for forming external threads on bicycle spokes sized 12G, 13G and 14G. Using a cold thread rolling process rather than cutting, the unit displaces material to create rolled threads that maintain spoke integrity and provide consistent thread pitch for reliable nipple engagement. Designed for use in wheel-building workshops and bicycle repair shops, this machine supports repetitive production of threaded spoke ends with minimal setup and no consumable cutting dies.

Advantages

The Cyclo CYC-07836 produces rolled threads that are stronger than cut threads because the metal grain is preserved and work-hardened during the forming process. It is compatible with common bicycle spoke sizes 12G, 13G and 14G, allowing a single machine to handle multiple spoke gauges. The mechanical operation provides repeatable thread pitch and reduces the risk of introducing stress concentrators associated with cutting. Its design prioritizes straightforward setup and routine use in workshop environments.

Suitable for

• Wheel-building workshops producing threaded spokes for nipples
• Bicycle repair shops that rethread or shorten spokes during wheel truing and repair
• Small-scale manufacturers or maintenance departments processing 12G, 13G and 14G spokes

When it may not be suitable

This machine is intended specifically for forming external threads on 12G, 13G and 14G bicycle spokes and may not be suitable for other spoke gauges, non-cylindrical spoke ends, or stainless steels and alloys outside the machine's recommended material range. It is not a universal threading solution for parts with irregular geometries or for threads requiring diameters or pitches outside the designed range.

Key specifications

• Supported spoke sizes: 12G, 13G, 14G
• Threading method: cold mechanical thread rolling (material displacement, non-cutting)
• Intended application: external thread formation on bicycle spokes
• Typical use environment: wheel-building workshops, bicycle repair shops, small production

How to use

Secure the spoke in the machine according to the manufacturer's instructions so the unthreaded end aligns with the rolling dies. Activate the rolling mechanism to form the external thread by advancing the spoke through the rolling dies; the rolling action will displace material and produce the finished thread profile. Verify thread length and pitch after forming and trim or deburr the spoke end if necessary before fitting a nipple. Follow routine maintenance and lubrication schedules to keep the machine operating consistently.

What to consider before purchase

• Ensure your shop works primarily with 12G, 13G or 14G spokes to match the machine's supported sizes
• Confirm compatibility with the spoke materials you use (carbon-coated, stainless, or alloy spokes may behave differently)
• Assess workspace, power and mounting requirements for safe, stable operation in a workshop setting

Usage recommendations

Use consistent spoke feed and alignment to ensure uniform threads; inspect the first few threaded spokes to confirm pitch and length, and maintain the rolling dies per manufacturer guidance to preserve thread quality and machine longevity.
