Norris, I have a 73/74 and here is what I can tell you about mine: the "clubs" cutout on the seat tube lug has the bottom radiused downward. The fork crown, on top, has them also with the bottom being radiused downward. The tangs inside the fork have a slightly different design: the stem of the club is elongated downward then the bottom is straight. The BB cutout is yet different again: the bottom of the club rather than being radiused downward is more angular....approaching a very, very slight V. Angel Garcia Long Valley, NJ
Subject: [CR]1971 Colnago Track Frame
snip> At first glance I had obtained my objective.. a resplendent flam ruby and chrome Colnago shone in the rays of the Provencal sun..but that world-renowned type face did not spell out Colnago... but Tinazzi. Tinazzi the former French pro has a tio shop just outside Marseill at Aubagne,famous throughout thre world as the setting for Marcel Pagnols poignant novels..
studying the frame I noticed the clover-leaf cut-out in the down tube-head tube lug, couldn't find any engraving on either the fork crown or top-eyes, but turning the bike upside down rejoiced at seeing the large Colnago motif cut out of the bracket shell.
My joy was short-lived as I was certain that this frame was no Colnago but a very subtle copy .. and well executed ...The "give-away" is that the foot of the trefoil is not flat but slightly radiused downwards.. not too much .. but sufficient not to breach Colnago's registered design. Clearly the seller had been duped... Other cyclists on the caravan site thought it to be original... but I am not too sure.. but it's a nice frame anyway.. The final word will rest with M. Tinazzi... if he ever replies to my email.
Can anyone help out here.. could it actually be a genuine Ernesto..?
