Introduction
To perform the core replacement on a Sturmey Archer RX-RK5 Hub you will need the following tools:
- Sturmey Archer Hub Core Wrench (available for purchase on the Biktrix Website)
- Adjustable Wrench
- Bike chain tool
- T25 Head Screwdriver/Bit
This service can be performed with the hub still laced into the wheel or with the hub standing by itself. However, the rear wheel must be removed from the bike to do this.
