I suppose the best ways to spot an Eric Rupe are  :daumenhoch:



1) Different brake bridge, only like that on 86 rupes onwards upto 1989. 1985 Eric Rupes have the same brake bridge as the pro class in the pic, look for the other difference's on these frames  8)




2) Thick top tube the same thickness as the down tube.  8)




3) 19.5 inch TT length, all other goose models are 18.5 inch top tube  8)




4) The seat tube is alot taller on the rupe than any other mongoose model  8)

OK Guys the plot thickens so bare with me, fooking mongoose  :LolLolLolLol:

I just got this 1988 Mongoose Eric Rupe although its stickerd as an 86. Putting the frames together ive noticed some slight differences to the 87 Mongoose Eric Rupe model i have.  :-\ :-\ ??? ???

First difference is the rear brake bridge is slightly lower on the 88 model. Second difference is the seat tube stick's out about 1cm further on the 88 model as well. Also the 88 model didn't come with a metal head badge. I was wondering if other people with these F+F could measure their's and see what measurements are, thanks dudes  :daumenhoch:

Please see pics below  ;)
