RFX Pro Series Armalite Aluminum Sprocket - 520 (Ref. FXRS 31-48 ALBU)

Designed for demanding riders, the RFX Pro Series Armalite double composite sprocket combines a machined aluminum core with a high-density steel outer ring. Ideal for both the Cross and Roadster environments, it incorporates technical solutions developed by RFX for competition while remaining suitable for road use.

• Material: CNC machined 7075 aluminum inner ring, HCS (high carbon steel) outer ring
• Configuration: double ring with Hex-Drive interface between the two parts to limit stress on the rivets
• Features: pitch 520, 48 teeth, blue anodized finish
• Design: CAD-optimized profile for lightweight, mud evacuation grooves, and rigid construction for better torsional resistance

This sprocket installs like a standard part: clean the hub, mount the ring onto the mounting holes, apply Loctite to the bolts, and tighten according to the manufacturer's torque specifications. It is particularly suitable for models branded by the manufacturer and can replace your original 520/48 tooth sprocket.
