With regards to info on the tubing, my Basso 'Coral' is about 2-3 years older than this one and is built with Columbus 'Cromor' if that's of any help or interest. Very similar build features such as rear brake bridge, chain stay bridge, lugs, drop outs and braze on parts. One big difference is mine has a crowned fork with the Basso logo stamped in either side of the top of the crown. Is your fork original? the unicrown fork looks a little out of keeping with the frame (just my opinion). Mine, like yours, also has very tight clearances, lovely frame to ride, I imagine you'll regret to see it go.
Hi Adam, thank you for the information, that's good to know. Yes, I think in 1995 Columbus had stopped making tubing for some reason, and so Basso basically took a lot of different brands of expensive steel tubing and put them together and branded the mix as their own, hence the 'Basso superlight tubing'. I'm sad to be selling it, it was a great ride, but just a tad too small I'm afraid. Yep, the fork is original, and I totally agree with you, it doesn't look incredibly, but it is very very light!
