title says it all.
Aluminum main tubes thermally bonded to the lugs.
It is a 26.8 which i believe is the correct size
It will NOT move.
Ive soaked it for about 4 days in pb blaster both externally and internally through the water cage hole.
Heat will do no good considering alloy expands faster than steel and given the frame/lug bonding chances are heating would compromise the frame.
i tried that freeze off crap. Dont bother. It barely dropped the temp at all. i would have been better off with a can of canned air for blowing out computers....turn that upside down and you get COLD. THis freeze off stuff is a waste of 7 bucks and about 2 hours of your life.
anyway...i 3 foot pipe wrench wouldnt budge it
what other options do i have other than cut the seat tube down and hack saw on it. im afraid to do this as the main tubes are aluminum and ill probably end up messing up the frame.
