Is it for aesthetics or function? Is it worth the cost to you? Your decision. Very nice bike. If it were mine, I would go modern with a threadless headset/stem, compact, 31.8 bar, and carbon fork. I am in the process of doing that to a Lemond Tourmalet. I just acquired the fork from Spaghetti Legs. I also switched to, 6750 crankset, and the rest is 6600. It already had 4600 shifters and they stayed. It is a fair investment for whatever gain there is or isn't. It is something I wanted to do, saw an opportunity to do it at, IMO, a low cost, and went with it.
