Vortex 435C-63 CAT5 Rear Sprocket 63 Tooth

The Vortex 435C-63 is a high-performance CAT5 rear sprocket featuring 63 teeth for modified gearing applications. Manufactured from premium 7075-T6 aluminum alloy, this sprocket delivers exceptional strength while reducing rotational mass compared to steel alternatives.

Key Features:

• 63-tooth configuration for increased top speed and reduced acceleration
• CAT5 construction uses 7075-T6 aluminum for optimal strength-to-weight ratio
• CNC-machined from solid billet for precise tolerances and perfect chain alignment
• Hard-anodized finish in silver provides superior wear resistance and corrosion protection
• Laser-etched tooth count and size markings for easy identification
• Steel inner hub insert prevents bolt hole elongation and ensures secure mounting

Vortex CAT5 sprockets are engineered for serious riders who demand maximum performance and durability. The lightweight aluminum construction reduces unsprung weight for improved suspension response and acceleration, while the hard-anodized surface treatment extends service life significantly beyond standard sprockets.
