The Cyclus Tools gauge checks and corrects the exact geometric position of the frame dropouts.
- To use the gauge, remove the wheel from the frame (fork) and clamp both gauges in the axle mount.
- Allow for the different axle diameters and installation widths: front wheel axle diameter – 9 mm, installation width – 100 mm; rear wheel axle diameter – 10 mm, installation width – 130/135 mm.
- Move the sleeves on the tool to ensure a good fit.
- If the dropouts are positioned correctly, the face planes of the gauges will be parallel. If the two sides of the tool do not align, the dropouts must be realigned accordingly.
