Thanks to a combination of a thief and a quick-release lever, my saddle and post were removed from my bike yesterday at the station. Have no fear, BTP are on the trail of the thief. In the emantime I needed a new saddle and post. My LBS measured the stem internal diameter as 25.4mm (an inch in real money). However, his 25.4mm stems could not be gripped tightly enough. The 25.6mm stems were too big, and did not fit. So now I have a 25.4mm plus an old coke-can acting as padding. Does anyone know what standard sizes stems are? Peter.
