This is a Batch 6 version HIGH QUALITY 1st gear cog for the Cyclone 5 Speed gearboxes. We have changed manufacturer and all Cyclone products, including complete gearboxes and spare parts, are made from the latest specification materials and vastly improved manufacturing methods giving greater strength and quieter running.
This gear cog is NOT manufactured by DRT but it designed to be used with all Batch 2 - Batch 4 versions marked 'DRT', and all subsequent RLC produced Batch 5 - Batch 6 versions, marked 'PZ'. This gear cog can be used with all Batch 2 - 6 Cyclone 5 Speed gearboxes that have a 9 tooth first gear on the cluster.
This is NOT suitable for very early Batch 1 gearboxes that have a 10T first gear on the cluster, or Cyclone 5 Pro gearboxes.
