I have a Pinarello, which I believe to be a Treviso (so Columbus SL). I bought it in late summer last year, had it powder coated, rode it once and decided it is a little too long in the head tube for me.
I haven't got around to stripping the bike down. Happy to send some photos across.
In brief - 61 ct, top tube is 58cm, head tube is c 19.2cm
Campag dropouts, rear brake cabling through the top tube, brazed on front mech, italian threaded bb, original chrome fork, chrome chain stay.
I'd be happy selling the frame, fork, headset (threaded, has been painted black at some point) and the bottom bracket currently fitted.
I'll send a PM to exchange e-mail details for pics etc.
