Title: JMC Euro/American BB ???????
Post by: (((sonic))) on September 21, 2009, 11:20 AM

Two JMC's, both Standard Shorts, one '83 the other '84 (7mths seperate them) different Bottom Brackets, (american and Euro) was this the cross over period? or was it whatever was in the parts bin at the time?

 No idea-both lovely frames though.Dunno about the cross-over period,but is perhaps one a mini/junior sized frame?A lot of companies had Euro bbs on their mini bikes during that period.

When I rode for JMC I had a Shadow with a euro BB.   So I don't think there was a standard with the bb's on JMC frames.

According 2 Jim when I spoke 2 him about mine. There is no rhyme or reason, built loads of F&F 2 order . So think it was supply and demand  ;)
