Rode around the Cwmcarn trail on friday. Did an experiment to see how low I could run the tyre pressures. Tried 18psi in High Roller 2.3" XC. Too low. I heard the rim a few times when going over rocks and took it easy over other bits due to being too lazy to get the pump out of my bag. By the end of the loop the tyre and inner tube on the front had rotated about 10mm.
Oops.
