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.
