I recently aquired a 60's Varsity. In tailoring the bike to my needs I have ran into a problem and seek advice. I need to replace the handlebars to 48cm Nitto Noodle 177 road drop bars. The Problem: The stem has a 25.44mm (1 inch) opening and the bars have a 26.0 mm center. The quill for the stem is 21.15.......whatshould I do?
