What is Bicycle Wheels, Saddle, Pedals & Accessories?

🚴 Bicycle Wheels, Saddle, Pedals & Accessories represents a complete system of precision titanium components engineered for Cycling / Bicycle applications. Long thin wire 200-300mm, small hexagonal nipples with internal threading, hollow axles with cam mechanisms, thin-wall tubing for cages/rails, small cleat plates The system integrates 14 distinct component types manufactured through 3 specialized processes.

Key manufacturing processes for this system include CNC turning Swiss-type for accessories geometry, Thread rolling DIN 13-1 6g with SPC sampling, Vibratory deburring with SPC sampling, Go/No-Go ring gauging with SPC sampling, CNC turning Swiss-type for wheel hardware geometry, each selected and qualified to meet component-specific requirements.

Engineering & Design Principles

Material: Grade 9 (Ti-3Al-2.5V) is ideal for spokes — higher strength than CP-Ti, excellent cold drawability, 40% lighter than steel. Grade 5 for axles and pedal spindles.

Form: Wire drawing for spokes and saddle rails. Bar stock for axles and pedal spindles. Tube forming for bottle cages.

Standards & Material Specifications

Standards: ASTM B863 Grade 9 wire / ASTM B348 Grade 5 axles, 100% tensile tested spokes, anodized

1 Part Feature Analysis

Precision-machined thin-profile toothed rings (cogs/chainrings), small-diameter pins/shafts, threaded fasteners with rolled threads, hollow spindles with bearing interfaces

  • ⚠️ Rotational inertia reduction
  • ⚠️ Wear resistance against chain rollers
  • ⚠️ Sweat/rainwater corrosion
  • ⚠️ Thread galling in aluminum frames
  • ⚠️ Fatigue under sprint torque 1500W+

2 Material Selection Rationale

Grade 5 Ti-6Al-4V — General alpha-beta alloy, high strength

Grade 5 (Ti-6Al-4V) provides ideal wear resistance, fatigue strength, and 40% weight saving vs steel for drivetrain components. Grade 9 for fasteners requiring cold heading.

3 Form Selection Rationale

Round Bar / Rod — for turning, fasteners

CNC machining from plate/bar for cogs and chainrings. Swiss-type turning for pins and spindles. Rolled thread forming for bolts ensures continuous grain flow for fatigue safety.

4 Manufacturing Process & Services

Core Processes:

CNC machining of tooth profilesThread rolling of all fastenersSwiss-type turning of spindles/pinsAnodizing/DLC coating

Toll Processing Services:

CMM tooth profile inspectionHardness testingFatigue testing (sprint load simulation)MPI of threads

Process Pitfalls:

  • ⚠️ Chainring tooth profile must match chain roller diameter to +-0.05mm for silent shifting
  • ⚠️ BB spindle taper requires +-0.01mm concentricity for bearing preload accuracy
