Two tyred

Switching the tyres from off-road to road was all very well,  but getting a pinch flat while trying to get the oh-so-tight road tyres back on meant getting a new tube. The guy in the bike shop took a look at my photo of the old tube, and then sold me a 28" tube for my 26" wheel. A trip back there today then to switch for the right size, and the bike is shod with road rubber once more.
