This tool is designed for centering wheels and checking their axial symmetry.
Use
- Unscrew the set screw until both measuring surfaces rest against the rim flank. Then turn the screw back until the measuring surfaces lift slightly off the rim flank.
- Place the tool on the opposite side of the wheel.
- You can then assess the wheel’s axial symmetry and, if necessary, adjust the spoke tension on the appropriate side to center the rim.
