RFX Pro Series Armalite 520 Sprocket ā 45 Teeth (ref. FXRS50-45ALBK)
Designed for demanding use in Quad, Cross, and Roadster applications, this RFX Armalite composite sprocket combines a CNC 7075-T6 aluminum core with a high carbon steel (HCS) outer ring. The result is a lightweight, rigid assembly designed to minimize tooth wear while maintaining high torsional strength. Anodized black finish for a racing look and enhanced durability.
Product developed and tested in competitive contexts, the Pro Series Armalite is aimed at demanding riders who want a robust, lightweight, and easy-to-maintain sprocket. For installation, follow the manufacturer's recommendations: clean the hub, apply appropriate Loctite, and tighten evenly to the recommended torque values.
