Precision Fit for Magene QED

Generic replacement bolts may differ in thread specification, shaft length or head geometry.

S-PARTS develops each component around its intended mounting interface to provide accurate fit and consistent installation. From derailleur mounting and adjustment points to pulley and shifter clamp hardware, every component is engineered for its specific application.

Careful control of thread dimensions, shaft geometry and head design helps ensure proper engagement with the corresponding mounting points.

Lightweight Grade 5 Titanium Construction

Each component is manufactured from Ti-6Al-4V titanium alloy, internationally known as Grade 5 titanium.

Grade 5 titanium combines excellent strength, low weight and corrosion resistance, making it well suited for high-performance bicycle hardware.

With a total weight of just 17.9 g per set, this kit offers a lightweight titanium upgrade for selected Magene QED drivetrain components.

Precision CNC Machining

Every component is precision CNC machined with dimensional tolerances controlled to ±0.02 mm.

This level of machining control maintains consistent geometry and dimensional accuracy across the kit. Key load-bearing fasteners also feature position-specific shaft diameters or structural designs according to their intended application.

Precision-Machined Tool Interfaces

Different fasteners use the appropriate tool interface for their specific installation points:

• 2 mm Hex
• 3 mm Hex
• 5 mm Hex
• T25 Torx

The bolt heads feature precision-machined tool recesses for secure tool engagement during installation and removal, reducing the risk of tool slippage when the correct tool is used.

Surface Treatment and Color Options

The surface treatments used across the range include vacuum nitriding and anodizing processes.

These treatments provide a range of distinctive finishes while enhancing surface durability, corrosion resistance and resistance to wear from regular use and repeated installation.

Available color options:

• Gold
• Rainbow
• Titanium
• Black
• Blue
• Green
• Purple
• Candy
• Indigo

Candy Finish Notice

Due to the unique coloring process, the Candy finish features a dynamic, fluid color gradient. Color distribution and pattern may vary from one set to another, giving each set a distinctive appearance.

Variations in color and pattern are a normal characteristic of this finish.

Thread Finish Notice

Slight uncolored or bright lines may appear on certain threaded areas during the coloring process.

This is a normal cosmetic characteristic and does not affect normal installation or product performance.

Installation Notice

Please install each fastener in its designated position and follow the torque specifications provided in the original component documentation.

Use the correct tool for each fastener and avoid excessive tightening.
