I believe that Merckx would have gone as fast in the hour on a heavier Colnago as on his superlight one. I believe that Rominger would not have gone any faster on a superlight Colnago than he did on his relatively heavy one. It appears that either Mr. Colnago changed his opinion on the usefulness of light weight in an hour record attempt - after all, he made very different bikes for each - or that he did not give Rominger as much support as he did Merckx.
I suspect - and this is pure speculation - that Colnago (and perhaps Merckx) knew all along that a superlight bike would not make a huge difference, but this was a great way of putting Colnago's skills (and Campagnolos upcoming superlight parts) into the spotlight. The hour record bike is a great achievement from a craftsmanship perspective, and whether it was necessary to achieve the record or not does not detract from that.
However, if you believe that a lightweight bike would have allowed Merckx to accelerate faster to his final speed - and considering that it took him two laps to get to that very high speed, this could be an important factor - then I am willing to accept that. -- Jan Heine, Seattle Editor/Publisher Vintage Bicycle Quarterly c/o Il Vecchio Bicycles 140 Lakeside Ave, Ste.
