i started on 48/19, then went down to 48/17. 48/18 is probably exactly right for london I reckon - 19 was too spinny at the kind of speed I like to go to keep up with traffic, but while I have no problems handling 17 generally, I do wonder if all the standing starts are going to take a toll on my knees eventually.
