If this is right then the reason for the position changeing could have been to do with different callipers coming on the market at the time. Wasn't the mid-late 80's when the mx1000 design was replaced?

Would have been MX901 by then, they might work better with a slight angle  :-\ :)

I love trying to figure out the why's . Mongoose seem to be pretty good at putting your brain into meltdown though :LolLolLolLol:

when ya get a minute measure the rider area on the rupe and pro class,,,,fromm centre of bb to middle of the steerer tube at the top

you will probs find there very close even though it has an extra inch on top tube but that looks to me like a more relaxed seat post angle

go on try it

Your right m8, even though the top tube is 1" longer than the Pro Class the frames are still the same size. Top tube is just abit longer to give the rider abit more room. :daumenhoch:

Jimmy/Madd Dogg - out of interest, what is this measurment on a Supergoose/Pro-Class/Rupe?   Sorry for the hijack.

Love the thread by the way, I love a good Mongoose analysis.
