Can anyone tell me why one would choose 1" Ahead over 1&1/8" or 1&1/4"? What are the benefits of oversized headtubes, integrated headsets and the like? I'm thinking about what to choose for a new steel frame, which isn't going to be an outdated affair. It's going to be a quite solid frame, probably sloping TT, fillet brazed, road-fixed.
