Premium Surface Finishes

PVD Vacuum Nitriding Finish

Available in Gold, Rainbow, and Black.

This advanced process forms a dense nitride layer on the titanium surface, significantly increasing hardness, wear resistance, and impact durability. The color is integrated into the surface layer for long-lasting appearance under demanding riding conditions.

Anodized Finish

Available in Green, Purple, and Candy.

Anodizing creates vibrant, eye-catching colors ideal for riders seeking a personalized and distinctive bike build.

Natural Titanium Finish

Titanium finish retains the raw appearance of Grade 5 titanium, showcasing its clean industrial aesthetic without additional coloring.

Aerospace-Grade Titanium Performance
