I have a Legnano Roma and a Gran Premio of almost the same age - 1960-63 - and both have Record derailleurs and Record hubs (engraved Campagnolo, not Legnano) and Universal brakes. The biggest difference in equipment is that the Gran Premio has a steel Legnano branded crankset, whereas the Roma has a Campy Record unit, and a plain seatpost instead of a Campy one. However, the most significant difference is the frame, although they look nearly identical - the Gran Premio is heavier and takes a 26.4mm dia seat post: the Roma takes 27.0. I think that Romas were mostly 531 or Columbus, whereas the GP mostly used Falck tubing. The GP was an adequate race bike, the Roma better.

Hi All
What's the difference between a Legnano Roma and a Gran Premio?
Also any idea when steel Legnano panto'd hubs started and aluminium ones took over, or did they run
concurrently?
Thanks
PS. Any CR folk going to the Ripley Bike Jumble on Saturday?
