Thanks to Rob Thompson for providing the following info for his Stephen Roche Bioracer (pictured)
“I got the frame from a guy who found it in a bike shop in Sydney. The story goes that a pro rider brought the bike out with him to Australia then sold it to the bike shop before leaving, this was common practice. The bike was stripped of its Campagnolo components and hung on the wall.
The size I think is 54
Italian bottom bracket
Internally routed rear brake cable
Seat tube 27.0 diameter (straight , not ovalized), Columbus sticker illegible, rear dropouts are Campagnolo
Carbon fork I guess not original
Amazing paint work with gold leaf”
I am grateful for David Cotter for sending me the following pics which have identified the tubing as Columbus Gara, plus the original steel fork- great find!

Hi Rob, I too am from Sydney. Very interesting that the bikes are both in Australia. Especially European built bikes which don’t seem to be found in iEurope lol ??? I have now sold the bike but is good hands and still in Oz.
