I have a '84 Trek 520 that I just got and low and behold the seatpost is stuck. I got the bike for a pretty good price and as it happens it's my size. I've been squirting PB Blaster down the flutes and all around the seatpost but it isn't moving. I've contemplated more drastic measures like cutting/stronger oils/acids/bases to get it to release, but the seat is stuck at what I feel is pretty much the right height for me (test fitting without riding).

So before I break out the sawzall/hacksaw or the hazardous chemicals, is there any reason to go further if it is set at the right height?

I was hoping to apply framesaver, but without the seatpost coming out I would be missing a good bit of the frame.

My thoughts are that before I get extreme I should wait and see if it fits me as is (waiting on wheels/tires and other ancillary parts). If it needs adjusting then I'd have to re-disassemble the bike, which I'm perfectly capable of doing, and then getting crazy on the stupid seized chunk of alloy, at the same time I'd apply framesaver.

The bike was neglected, not abused, as far as I can tell it has around 1676 miles, at least that's what the Sachs Huret cyclo(non)computer says. I bought it from a gentleman that was cleaning out his late grandfather's basement who said it was there for probably at least the last 15-20 years.

I also know that BF members don't reply to a thread about a bike unless it has pictures so here are some before pictures.
