I bought this old bike a month ago. I've been trying to find info of what frame it is but...difficult. I think it might be Columbus tube but only because there is that one logo which previous owner has put there and it’s a light frame. There is also shimano 600 and campagnolo stickers but...doesn’t tell much.
It has been painted over and under the silver grey there is yellow, green, orange and red (maybe not originals). It has dura-ace headset, sr stem, campa super record rear mech, shimano 600 cranks, breaks and front mech. Wheels are wolber super champion tubular with campaganolo record hubs. It’s a really mixed up combination. Only lugged part is with top tube and seat tube. What frames were made with only one lugged part? It has also eyelets in rear and front dropouts. Under the bb there is only AC 3294. Can anybody help me to find out what this frame is?
I just became curious. It’s a really nice and light machine to drive.

a closeup of the seat cluster may help, too.

Thanks,

here is more. i took the saddle away. the Bike came with brown leather/suede san marco seat and im cleaning it.seat post is campagnolo i think. there is a really strange metal plate as a bridge where the rear brake is. with two drilled holes. maybe for the fender in winter training? Could it be that somebody has just welded by him/her self this frame? my guess is that the bike is from 80's.

this one too

What nonsense im talking. its not lugged at all. the seat tube is just having that holder.

You sure it's a light bike?
From what I can tell, it looks like all welded joints, and the chainstay and brake bridges look very low quality. But with the parts it has on it, someone must have loved it dearly. I have seen that type of brake bridge on Austrian bikes, sorry I can't be more help.

I know, it looks low quality and not really well made. I think i can weld better Haven't weight it but it is quite light. i have also old steel pinarello frame, not the top one, but this is in the same cathegory as weight wise. it is a bit mystery. really nice parts and wheels but the frame looks like from the other planet...Thanks anyway from trying to help me you all. I'll keep it as a commuter and don't put it to the parts, at least not yet. Handle bar is also somekind of nice sakae, golden 3D circle details and nice eagle on it.

The flat metal plate above the rear brake permits one to affix a Pletscher "mousetrap" rack without scarfing up the paint on the seat stays. There is often a similar drilled plate, with one large hole, under the chainstays for attaching a Pletscher kickstand. I have seen these feature on various lower-end Swedish, Dutch, and Austrian bikes. You may have a Crescent (Sweden) or a Steyr-Daimler-Puch (Austria).

Did Crescents have unlugged construction. If I rebuild the whole bike could there be info inside the bottom bracket shell. I havent taken fork off to check if there is info too. In our family there is a 70's 3-speed Monark super sport which has that type of rack and kickstand. It is also nice bike to drive but this has much more lighter frame.

thanks, Im trying to find info from crescents and puchs. I'll let you know if I found out what this frame is.

CampyGuy

The only info on the inside of the bottom bracket would be what type of threading it has.(English, French, Italian, or Swiss)
