Precision milled inspection tool to detect bent fork stanchions.
Hold the tool frontally on the uprights. In the case of bent studs, the tool is tilted at one of the 4 support points.
This does not necessarily have to be caused by an accident, even after mounting the front wheel under tension, for example after a tire service, the tool can tilt.
In this case, a loosening of the triple clamps can already provide relief.
