Description

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

The dual sprocket design offers optimal performance, reduced weight thanks to a 7075-T6 aluminium centre, and a longer lifespan for the teeth due to the high-density carbon steel exterior.

The Armalite sprockets also feature a hexagonal interface between the inner and outer ring, a groundbreaking technology for sprockets that maximises the transmission between the two parts and reduces the force on the rivets to zero.

Features:

CNC 7075 aluminium inner ring
HCS outer ring
Hex-Drive placement between the inner and outer ring
Profile designed with CAD for added lightness.
New mud clearance groove style to reduce wear.
Stiff design increases torsional strength.
Anodised colour

Installation instructions:

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 with a wrench.
Remove all nuts and the worn sprocket.
Clean the surrounding area of the hub, ensuring it is clean and free of debris.
Take the new sprocket and place it on the hub, ensuring it fits snugly and the bolt holes are correctly positioned.
Clean the bolts and nuts for the sprocket.
Apply blue Loctite to each bolt and insert them into the holes.
Screw the nuts onto the bolts by hand, making sure the seals are intact and in good condition.
Keep the hex key in place and tighten the nuts evenly.
Tighten the nuts and bolts according to the user manual.
Replace the wheel on the bike, making sure the chain is properly aligned and tightened to the manufacturer's specifications.

Features:
