The RFX Pro Series Armalite sprockets are designed and tested at the highest level by race teams in world and British championships.

The dual-sprocket design offers optimal performance, reduced weight due to a 7075-T6 aluminium centre, and longer tooth life thanks to the special high-density carbon steel outer layer.

The Armalite sprockets also feature a hexagonal interface between the inner ring and the outer ring, a groundbreaking technology for sprockets that maximises the transfer between the two parts and eliminates any force applied to the rivets.

Features:

• CNC 7075 aluminium inner ring
• HCS outer ring
• Hex-Drive interface between the inner and outer rings
• CAD-designed profile for lighter weight.
• New mud release groove design to reduce wear.
• The rigid design increases resistance to twisting.
• Anodised colour

• Start by placing the bike on a stand, with the rear wheel off the ground.
• Remove the chain and the wheel from the bike.
• While holding the hex key, loosen the nuts using a spanner.
