Product Description

Industrial Aesthetics, Refined by Titanium Engineering

The pursuit of industrial beauty begins with precision engineering.

S-PARTS transforms functional bicycle components into refined design objects through CNC machining and advanced surface treatment technologies, redefining the visual identity of modern cycling builds.

Grade 5 Titanium Construction

Machined from Ti-6Al-4V (Grade 5) titanium alloy, widely used in aerospace and motorsport applications.

  • Tensile strength: ≥1050MPa
  • Approximately 50% lighter than steel equivalents
  • Excellent corrosion resistance (rain, sweat, salt exposure)
  • High structural stability under long-term cycling stress

Shimano Hollowtech II Universal Compatibility

Compatible with:

  • Shimano XT
  • Ultegra
  • Dura-Ace
  • SLX / Deore (Hollowtech II system family)

✔ MTB & Road universal fit
✔ Designed as a preload adjustment cap (not a load-bearing bolt)

Function & Installation

Replaces the original Shimano preload cap to:

  • Adjust crank bearing preload
  • Remove crank play
  • Ensure smooth drivetrain rotation

Installation Tool: 10mm Allen Key / Hex Wrench
(No Shimano TL-FC16 proprietary tool required)

Recommended torque: 3Nm
