Alreet Jim sweet framesets..Only had a supergoose 3 as a kid rode pretty good...what do the rupe and pro class ride like in the modern world?

hey jimmy

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

Would there be a big big biff between the Eric Rupe 1984 and cali ? AtariAger ,just asking as new to all this

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.

Thanks for posting the pics and info up Tom, great info if we need it.  

Seems the later the frames are the bigger the seat tube and thicker the rear drop outs are, wonder why they decided this

They're all different to a cali mate - cali has thinner tubes for one and some calis aren't full chro-mo. There are many other subtle diffs too.

Good thread Jimmy

Just a thought but taking into acount what russ has said. Was the reason for the brake bridge design to make sure the calliper sat in the right position, after relaxing the seatpost angle?
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

Great isn't it - every discovery unravels a new mystery

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.
