Hi, It's been a while since the last post but I wanted to get some more information from you.
Recently, I managed to buy a rather unique bike in very good condition and in the original specification. The whole thing is on the Deore II MT-62 group and on a frame similar to the one in the subject.
Looks like a Gilles Berthoud frame to me. From what I've found, it's a hand-made frame. There is no serial number on it, so it's hard to say what year it was made.
Equipment full group from 1989 so I think that was also the year of production.
Do you know anything about Gilles Berthoud producing frames for other companies ? The bike I bought is in perfect condition. The rims are like new.
I'm just wondering if it really could be Gilles Berthoud and is it known if a lot of such bikes were made (unfortunately there is no serial number of the frame here)?
