Description

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

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

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

Features:

CNC machined 7075 aluminium inner ring
HCS outer ring
Hex-Drive location between the inner and outer ring
CAD-designed profile for lightweight construction.
New mud-clearing groove style to reduce wear.
The rigid design enhances torsional resistance.
Anodised colour

Installation instructions:

Start by placing the bike on a stand with the rear wheel off the ground.
Remove the chain and wheel from the bike.
While holding the hex key, loosen the nuts using a wrench.
Remove all nuts and the worn sprocket.
Clean the hub area ensuring it is clean and free of debris.
Take the new sprocket and place it on the hub ensuring it is properly fitted with the bolt holes aligned.
Clean the bolts and nuts for the sprocket.
Apply blue Loctite to each bolt and insert them into the holes.
Hand-tighten the nuts onto the bolts ensuring the seals are intact and in good condition.
Hold the hex key in place and tighten the nuts evenly.
Tighten the nuts and bolts according to the user manual.
Reattach the wheel to the bike ensuring the chain is properly aligned and tensioned to the manufacturer's specifications.

Features:
