THE NEXT GENERATION OF VORTEX SPROCKETS

Vortex’s proven CAT5 sprockets are already lightweight, but the new V4 line pushes that further. With a 10-15% reduction in weight compared to CAT5, and no compromise in strength, the V4 is built for riders who expect more from their drivetrain. It’s not a replacement for the iconic CAT5, but it raises the bar for performance aluminum sprockets.

KEY FEATURES

• Precision-machined from high-strength 7075-T6 aluminum
• Machined front and back for optimized weight balance and rigidity

PERFORMANCE BENEFITS
