Building up a road hack whilst I nurse my back, back to fitness, so looking for something around 18" with canti mounts upto about the £50 mark, though easily swayed by the right fancy stuff. Has to have canti mounts though, as those are the bits I have in the shed.
I've got this which is built up, but I could take apart. It's 6061 alloy very light and v brake only. £50 posted should do it. I've also got a slightly larger Marin Muirwoods, steel, again v brake only and £50 posted email me for pix of Muirwoods if interested Martin fnnerhorneATntlworldDOTcom
