Features

Specifically Designed for SRAM RED AXS E1

Designed exclusively for the SRAM RED AXS E1 8-bolt direct mount crank interface, ensuring precise dimensions, excellent thread engagement, and an OEM-quality fit for secure installation.

Ultra-Lightweight Performance

Weighing only approximately 4.9 grams per set, this titanium hardware significantly reduces weight compared to the original steel bolts while maintaining the strength required for demanding road riding.

A simple upgrade that complements premium lightweight bike builds.

Aerospace Grade 5 Titanium

Manufactured from premium Ti-6Al-4V (Grade 5 Titanium), the industry standard for high-performance cycling hardware.

Benefits include:

• Outstanding strength-to-weight ratio
• Average tensile strength exceeding 1050 MPa
• Excellent fatigue resistance
• Exceptional corrosion resistance
• Rust-free performance
• Approximately 45% lighter than comparable steel fasteners

Built to perform in all weather conditions while maintaining long-term reliability.

Hot Forged for Superior Strength

Unlike ordinary titanium bolts machined directly from bar stock, every S-PARTS spider bolt begins with a precision hot-forging process using custom-engineered tooling.

Hot forging refines the titanium's internal grain structure, improving mechanical strength and consistency before final machining.

To maintain exceptional forging accuracy, each die is carefully controlled through limited production cycles, ensuring consistently high manufacturing standards.

Precision CNC Machining

Following hot forging, every bolt is finished using high-precision CNC machining equipment with micron-level tolerances.

This manufacturing process provides:

• Accurate thread dimensions
• Smooth thread engagement
• Excellent fitment
• Reliable torque consistency
• Premium surface finish

Every bolt is individually inspected before packaging to ensure consistent quality.

Premium Surface Finishes

PVD Vacuum Coating

Available in:

• Gold
• Rainbow
• Black
• Blue

Using advanced Physical Vapor Deposition (PVD) technology, a dense metallic nitride layer is permanently bonded to the titanium surface.

Benefits include:

• Increased surface hardness
• Superior scratch resistance
• Improved wear resistance
• Excellent color durability
• Long-lasting premium appearance

Unlike conventional painted finishes, PVD coatings resist fading under normal riding conditions.

Anodized Titanium Finish

Available in:

• Green
• Purple
  
• Candy
• Indigo

The anodizing process creates a controlled titanium oxide layer that enhances corrosion resistance while producing brilliant metallic colors through optical light interference rather than pigments or dyes.

Each finish displays subtle color variations depending on lighting conditions and viewing angle, giving every bike a unique appearance.

Natural Titanium Finish

Available in:

• Natural Titanium

The Natural Titanium finish preserves the authentic metallic appearance of Grade 5 titanium without additional coloring treatments.

Its understated industrial aesthetic highlights the material itself while retaining titanium's outstanding natural corrosion resistance.

Package Includes

• Titanium 8-Bolt Spider Bolt × 8

Compatibility

Compatible with:

• SRAM RED AXS E1 Crankset

Designed for the SRAM 8-bolt direct mount spider interface.

Please compare your original hardware before ordering to ensure compatibility.

Installation

• Recommended tightening torque: 4.5 Nm
• Use a T20 Torx wrench.
• Tighten the bolts evenly using a cross pattern.
• Apply a thin layer of anti-seize compound to the threads before installation.
• Always follow SRAM's official installation procedures and torque specifications.

Installation Tip

Titanium fasteners installed into aluminum cranksets or spiders may experience thread galling (cold welding) if assembled dry.

For optimal installation and easier future maintenance, S-PARTS recommends applying a high-quality anti-seize compound to the bolt threads before tightening.

Using anti-seize helps to:

• Prevent galling between titanium and aluminum
• Reduce thread friction
• Improve torque consistency
• Protect threaded components
• Simplify future removal and maintenance

Note: Apply only a thin, even coating of anti-seize compound. Excess lubricant may affect the actual clamping force.
