🚲 Bicycle Cockpit, Steering & Control Hardware

Precision fasteners M4-M6 with low-profile Torx heads, thin-wall tubular spacers, complex 3D-printed structural brackets, small-diameter pivot pins

Design Principles

Material: Grade 5 (Ti-6Al-4V) mandatory for all cockpit safety-critical fasteners (stem bolts, lever pivot pins). Grade 9 for non-structural fasteners. Never use aluminum for stem bolts.

Form: Bar stock for precision fasteners with rolled threads. 3D-printed (SLM) Grade 23 for custom stem bodies — zero material waste, optimized topology.

Engineering Trends

  • ▸ Process: CNC turning of bolt heads and threads
  • ▸ Process: Thread rolling (all safety-critical bolts)
  • ▸ Process: SLM 3D printing of custom stem/adapter bodies
