1996 Specialized A1 Comp Ground control , rear end questions and build ...

[fiendish feet]

Just picked up an old tired Specialized Comp Ground Control frame
Basically as a winter hack .
So it arrived today and ive started cleaning it up ..
All the pivot bolts were over tightened so no movement in the linkages ..
Ive removed the main bolt from the Bb pivot point , and have some wiggle in the rear end
But it does not want to be removed , Can any member advice me on what im missing to remove the swingarm ...
Any diagrams ,links etc

It's probably just pressed in - You could either drift it out, but that might stress the swing arm, OR, make a quick and dirty puller, with a socket large enough to span the circumference of the bushing but still bear on the swing arm, feed a long bolt through from the back side (maybe the one that came out of it), and out through the socket, put a nut and washer on it, and then tighten the nut, pulling the bushing out, into the socket.
Whew - That was a long sentence......

Thank you , in that case i might flush out the bushing with gt85 and reassemble ...
Till i gain the confidence to give it a crack ...
Back to polishing the seat post ..

Bb shell inspection , well glad the bottom bracket came out quite easy .. but i dont think ive ever come across such a mess before ....

When I broke down my Parkpre (also aluminum frame), the BB shell looked like that.
It was really just from the disintegrated BB itself - Just vacuum up the worst, clean the threads with a little wire brush, and I bet it'll be fine.

Yes cleaned up quite nice , the removed Shimano Bb wasnt that bad on removal looks as if some one just screwed a new bb in ,without removing the previous detritus ...
it fell out basically .. i was expecting to have to use an extension bar to remove it ...

I have to keep reminding myself that this bike is only to get the shopping from town ,
Which im paranoid about leaving any bike longer than five minutes , in any town ..
And i must remember this isnt about pulling a babushka on the way , with shiny retro objects ..
