I'll echo what other people have said-

If you want a carbon bike- get a carbon bike. This will never be a carbon bike.

This is a special frame- especially because it was specially built for your grandfather. It's a quality frame, made from quality materiel.

If you get the frame/fork painted- spring for the decals- once the frame is painted and it leaves your possession- it just becomes "an old bike" like millions of others- and on some forum somewhere there's going to be a "Identify my mystery frame" thread and no one is going to know what it is.


Where I get a little different is that I would build the bike a little more easily sourceable. I think your brakes are the gem as far as components- keep those. But the rest of the stuff- I'd find a quality 70s 10 speed and transfer the parts. Because I'm a dork- I'd go with Suntour Cyclone 1st generation derailleurs, Simplex Retrofriction shifters and a Stonglight 99BIS crankset. Lightweight, impeccable performance, certifiably "vintage," and undeniably badass.
