Brazuca, sounds like you and I are exactly the same size - 6-foot-nothin' with long legs. A 23" frame feels smallish, and 25" frame is OK, but maybe just a tad tallish.

If you don't mind me hijacking your SuperCourse-specific thread, I'd like to ask other forum members if they know of any lightweight lugged steel 24" frames I should be looking for? My ideal n+1 bike would be a touring (with cantis) frame, but made with a reasonably light tubing set. With a 24" CTC seatpost.
