A few day ago I got this bike from a friend for a restoration. He thinks it's bianchi but I am sure it's not. It has Wienman brakes, simplex derailleurs, 3ttt steam, ofmega hubs and ofmega crankset. Because of the age of the parts (1970) and frame details I think it's French Motobecane but can someone confirm or can be sure it's something else. Thanks
Old French bike parts have different size standards than Italian ones. See http://www.sheldonbrown.com/velos.html for list. Probably the easiest part to measure is the bottom bracket width, which is 70mm for Italian and 68mm for French bikes.
Sometimes bicycles or frames are found with no makers’ transfers or badges on them –and occasionally with badges/transfers that are not correct! In these cases examination of the frame number – where it is, what it is, and how it is, may be of some assistance at least in allowing other specialists to hazard a guess at the true origin of the frame or machine. This note was begun before the V-CC published the two volumes of Lightweight Catalogues wherein the various marque enthusiasts (ME’s) had set out frame number lore for their makes. These publications have been invaluable in adding accuracy to the information – but even including their data there are still well over 200 makes of possible lightweights to be confused over! The author would be grateful to know of any inaccuracies and to receive further information to make the tables more comprehensive. Examine the bicycle for the location of the frame number Examine the frame number –what does it contain? Examine the type of character
Few hours ago I went to a old local bike shop and they confirmed the bike is Italian. They said it was messed up with frame color and parts, it was more like tourney bike because it has holes for fenders but it was quite good back in time. Italian database it a lot bigger then French so search continues! :) This puts me back to start.
