Vortex 526ZK-42 CAT5 Rear Aluminum Sprocket 42-Tooth 525-Pitch Silver

The Vortex 526ZK-42 is a CAT5 series rear aluminum sprocket featuring a 42-tooth count and 525 chain pitch, designed as a high-performance upgrade over the heavy OEM steel sprocket. Vortex sprockets are a lightweight, high-performance alternative to the steel stock sprocket.

Key Features:

• 42-Tooth / 525-Pitch rear sprocket for precise gearing adjustments
• 100% CNC manufactured in the USA from a specially formulated alloy per Vortex specifications
• Made with highest quality 7075 T6 aluminum — the best grade material for lightweight and durability
• Silver anodized finish to prevent corrosion
• Saber tooth grooves with a unique tooth design that increases sprocket longevity
• 100% CNC machined with saber tooth grooves
• Vortex patented sprocket design unlike any other sprocket

The weight saved on drive components is multiplied as rotating mass — less rotating weight improves acceleration. The perfected tooth design has less drag and reduces friction for better acceleration and deceleration.
