Re: Seat post stuck
Was just talking to my bro about this and I asked him what he did.
He cut the top off the seat tube for enough to grip on about 5cm or a couple inch's, then he used a hacksaw and a sawz all to cut into the metal along the inside length of the pipe, then that would allow the circumference to shrink a bit while twisting with your pipe wrench or vice grips.
(His was aluminum)
And use some liquid wrench or penetrating oil as well if you can.
I love my Motor Bicycle, I love Beer, I'll try not to like them both at once.
