The R1WURKS Ultra-Lightweight Titanium HD CVA Bones (X67mm) are engineered for racers chasing maximum efficiency and response in stock classes. Crafted from specially treated Ti 6Al-4V Grade 5 Titanium, these are the lightest CVA bones R1WURKS has produced, dramatically reducing rotational inertia for faster acceleration and sharper braking.
Optimized for 21.5–17.5 stock racing, these bones deliver improved power transfer, better cornering agility, and a noticeable reduction in overall drivetrain mass—giving stock racers a real competitive edge.
