Many years ago, way before prop stands were usually fitted to bikes, and one had to use a pedal on the kerb to hold the thing up, I bought a double armed prop stand that I wish I could get again. It had two arms so the bike rested on them without putting strain on the frame, and these two arms were pivoted such that they came together as they were raised and moved apart as they were lowered. Does anyone know of anything of the sort still available?
