Here'a an old steel Basso converted to a single-speed bike. I keep it in the midlands for riding around the undulating lanes north of Coventry on my frequent trips back there. I scrounged the frame. forks and wheels off a mate who has emigrated (on condition that he can have them back if he ever comes home). Most of the other bits came from my junk box. It only cost me £25 for cables, bar tape and tubes !
Its been slacker
I have a non-round chainring, which is a bitch. Its bad aswell, but it hasnt come off yet, i think its been close when i let it go really slack once, but no real problems with it like that. Working pretty well at the moment
I have 3 bikes, all steel. This is the one I use the most - I love it. It's also the oldest by a long way; c.1980. I'm thinking of treating it to some flashy bar tape or maybe even a respray, but I also want to preserve it so I'm torn. I'll probably remove the rear brake some time as I don't use it.
