Vortex 253ZB-53 CAT5 53-Tooth Black Rear Sprocket

The Vortex 253ZB-53 is a 53-tooth rear sprocket finished in Vortex's signature solid black hard-coat anodize, part of the CAT5 rear sprocket series. Machined from aerospace-grade 7075-T6 billet aluminum, this sprocket delivers a significant weight reduction over steel alternatives, lowering rotating mass and sharpening throttle response.

Vortex's patented saber-tooth groove design sets this sprocket apart from conventional units, extending service life by reducing friction and wear on both the sprocket and chain. The solid black PTFE-bonded hard-coat finish provides a durable, low-friction surface that resists corrosion and wear far longer than standard anodizing.

Key Features:

• 53-tooth rear sprocket for performance gearing tuning
• Manufactured from 7075-T6 billet aluminum for maximum strength-to-weight ratio
• 100% CNC machined in the USA to tight tolerances for a perfectly concentric fit
• Solid black hard-coat anodize finish — PTFE-bonded for enhanced durability and reduced friction
• Patented saber-tooth groove design increases sprocket and chain longevity
• Reduces rotating mass for improved acceleration and throttle response
• Part of the Vortex CAT5 rear sprocket series
