My Graftek might have been lighter (or maybe not, it was a 63 cm) Ended up 17.4 lb but could have been under 17 with superlight tubulars. Not bad for such a large frame in the '70s.
Mine had Hi-E rims too, and the front wheel had Hi-E aluminum "Siamese" spokes (I know, we don't use that word for conjoined twins anymore, but that was a different time...) Hi-E pedals too, which might be lighter than whatever weirdo pedals Jim's bike has there. (Weirdo is a word of praise, to me, they look cool!)

I sold the bike before I got around to making a lighter seatpost for it. Not that the Campy on there was too much of a pig, but my goal was to have zero Campy, and the post was the last holdout. A guy in Nederland bought it. I wonder how many Grafteks went to Europe?
