• Reliable clamping performance

Every detail is engineered to meet the expectations of performance-focused cyclists.

Advanced Surface Finishes

PVD Vacuum Nitriding Finish

Applied to:

• Gold
• Oil Slick
• Black
• Blue

Benefits include:

• Increased surface hardness
• Improved wear resistance
• Enhanced impact resistance
• Superior color durability

The PVD process creates a dense nitride layer on the titanium surface, producing rich metallic colors with excellent resistance to fading and abrasion.

Anodized Titanium Finish

Applied to:

• Green
• Purple
• Candy
• Indigo

Benefits include:

• Enhanced corrosion resistance
• Increased surface durability
• Brilliant metallic color effects

These colors are created through controlled oxide-layer thickness rather than dyes or pigments, producing the unique visual characteristics that titanium anodizing is known for.

Natural Titanium Finish

Applied to:

• Titanium

Features the authentic metallic appearance of raw Grade 5 Titanium, highlighting the clean, technical aesthetic of aerospace-grade titanium without additional color treatments.
