I have a nice Nitto Technomic extra tall quill stem which is designed to take narrow diameter bars (25.8mm?, forgotten, you know what I mean). I want to fit some alloy drop handlebars which have the least possible drop and forward reach, 42mm wide would be best. Modern shape, ie with straight sections under the levers and indents for cables to go under the tape if poss, but can't ask for the impossible. Any recommendations?
