What the FARK is this doing here fer *****s sake??!!?

Moving our bludy thread? Best info found on roadbiking in all the forums was found in this thread. Not our fault the rest of ***** in the roadbike forum is so crap that our cricket talk make's it look off topic.

Might as well ask a friggin MTB question now this thread is in with the "How do you put dose dang grinnin fools in mah post??", and "Whats dat dang foul smeel coming from mah pumper?".

Anyway, you girls know I've got an old 1990-92 (buggered if I know) Trek 920. Anyway, finally put a new chain on it for the first time today. Went to ride it, and it's always jumping the front cogs when I step on it. The cogs don't looke to badly shark toothed, but I'm assuming they are to worn out. So time for some new chainwheels. Only thing is, I can't see how to get them off. They look riveted with huge arsed rivets to the spiders on the crank, so how does one change the chainwheels? Will I have to throw new cranks on it as well or something?
