A lower tube on the trellis frame of the Gummicow gets rubbed by the boots, especially so it you use MX boots with lots of external reinforcements. Mine had lost a lot of paint down to the bare metal.
That inspired some rock song themed repairs!
Sanded the area, painted it with some rattle-can black and attached Touratech small frame guards. We’ll see how that helps. Next long tour is two days from now, to Dresden, to visit my son.
