Product Features

Designed for SRM PM9 Power Meter Cranks

Specifically developed for SRM PM9 crank arm pinch bolt assemblies.

The threaded side and non-threaded side versions are available separately, allowing riders to select the correct replacement component according to their crank configuration.

Premium Grade 5 Titanium Construction

Made from aerospace-grade Grade 5 Titanium (Ti-6Al-4V), offering an excellent combination of strength, corrosion resistance, and lightweight performance.

S-PARTS carefully selects premium titanium materials through continuous laboratory comparison testing and strict quality control.

Material performance:

• Tensile strength average: over 1050 MPa
• Exceeds industry standard requirements
• Mechanical performance comparable to Grade 10.9 steel hardware
• Approximately 50% lighter than traditional steel components

Titanium delivers an outstanding strength-to-weight ratio that conventional metals cannot match.

Precision CNC Machined Manufacturing

Each pinch bolt nut is manufactured using high-precision CNC machining technology with strict dimensional control.

Micron-level tolerance management ensures:

• Precise thread engagement
• Accurate fitment
• Reliable clamping performance
• Long-term durability

Every detail is engineered for premium crank system performance.

Titanium Anodized Finish

Available Colors:

Green / Purple / Candy / Indigo

Created through electrochemical anodizing, forming a controlled oxide layer on the titanium surface.

No dyes are used. The unique colors are created by the interaction between oxide layer thickness and light reflection, producing a natural titanium color effect with excellent visual depth.
