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 provides optimal performance, reduced weight thanks to a 7075-T6 aluminium centre, and a longer lifespan of the teeth due to the high carbon density steel outer ring.
Armalite sprockets also feature a hexagonal interface between the inner and outer rings, a revolutionary technology for sprockets that maximises the transmission between the two parts and completely eliminates the force on the rivets.
Features:
- CNC 7075 aluminium inner ring
- HCS outer ring
- Hex-Drive location between the inner and outer rings
- CAD-designed profile for lightweight.
- New style of mud release grooves to reduce wear.
- The rigid design increases torsional strength.
- Anodised colour
