Right, that´s what it is, a sleeve. I had been wondering about my own
ca. 1963 Cinelli frame and why there was this funny seatlug leaving the
seatpost without contact to the seat tube. I only finished putting the
bike together on Thursday.
I wonder if they also brazed the sleeve into the seatlugs of B models?
I´m still not certain about mine as it is not in original paint, and I
have been wondering why there´s chrome on the (SC sloping crown) fork
and none on the frame.
The b/b on my bike rumbles horribly. It´s my luck that I´ve got the
model with the wider b/b shell, so no modern stuff will fit. The axle itself is quite ok, but the cups and balls will have to be replaced. Where do I get these older Campag spares? Please keep in mind that I´m
not really into Campag (the whole Cinelli bike was a chance find), so I
hope I haven´t overlooked anything obvious.
