Thought I'd post these seeing as there are so few of them kicking around in the UK.
It's a 59cm Dancelli frame in what I believe to be crimped Columbus SL. There have been suggestions that some of the Dancellis were made by Colnago, but I've never seen any hard evidence.
I've built it up mainly for commuting as a 7-speed currently, with a wide-range block.
Shifters and rear mech are Chorus, chainset is C-Record, Campag skeleton brakes, and a 27.2mm aero seatpost.
It's a great ride; awesome handling once up to speed.
