Hi Norris,

Thanks for the informative and detailed post. I have not spent anywhere near the time that you have researching this frame, or the marque, but I have found it difficult to find much real information on the internet about anything to do with Mercier.

I'm afraid I can't shed much light on the history of this frame. My wife was living in France when we were just boyfriend and girlfriend, and she was doing a bit of cycling with her local cycling club. She could only afford one bike, so she had a mountain bike, and spare slick tyres for the road.

One of the elder statesmen of the club decided that she needed a road bike if she was going to be road riding, and so gave her this bike that had obviously been "done up" for winter use, with a selection of cheap parts (i.e. unbranded wheels, mix of cheap sachs and shimano gears, etc). I think the only original part still on the bike was the seatpost.

If it is as you say, a top end custom frame (perhaps even a pro frame?), it seems surprising that it would be relegated to this status, however I wouldn't ever condemn anyone for taking a utilitarian point of view, after all these bikes were designed to be ridden, and it's fair to say that this one has had a lot of use.

Are there any further measurements of photos I could take to help in the identification? Would external tube diameters help, or were they all much the same in those days? I think some columbus tube sets had internal ribs that I could look for?

I've searched high and low for a frame number, but couldn't find anything, which agrees with Hugh's assertion that it would've been on the headtube badge.

If it was an 80's model, that would give me a dilemma - I have a pair of wheels; Mavic 500 hubs laced to SSC rims, which would be really fitting on a bike like this, however they are actually getting very good use at the moment on my perfectly modern and contemporary cyclo cross bike (well, I rebuilt the rear onto a Hope hub, but I could always put it back the way it was). Perhaps some parts are just too good for putting in a case and admiring, and I'll have to find something else.
