Hi All,
I have a question about tubing used on Italian bikes in the mid-60's. Someone gave me a Bottecchia frame that I believe to be a 1967 model. It has Campagnolo 1010 long slot dropouts and forkends and the guy I got it from removed a nearly complete Nuovo Record group that the original owner told him was original so it seems reasonable to believe it was the Professional model. It bears a strong resemblence to my '72 Bottecchia Giro d'Italia frame but for a couple of differences: there are no spiral ridges in the steerer tube like there are on my '72 and it takes a 26.8mm seat post instead of 27.2mm. Those things would tend to indicate that it is not Columbus SL type tubing. But what then? It appears to be Bottecchia's top of the line frame from the period but now I have no idea what it is made of. The 22" frame weighs 2165g and the fork weighs 727g if that is of any help. Thanks.
