I'm 15 years old in high school and I ride my bike to school everyday 5km in Toronto, Ontario so as you might know, there's a lot of snow at times. I lock it up outside which I hate but I have no choice otherwise. I had a loose seat and I decided not to fix it right away and just ride on it anyway. Soon enough I wore down the grooves on the seat post so my seat couldn't get tightened thereafter. I took it in to the shop to get a general tune-up like switch my summer tires back and to get a new seat post. Turns out he couldn't get my seat post out. He first put it on a stand and even used the whole bike as a lever point, but it was STUCK. He then tried to saw it out somehow with no prevail and finally as of yet he took it to a welder to try and melt the sucker out of there but no luck. Tomorrow he is going to try and ?burn? it out with diesel fuel and if THAT doesn't work he is going to get it drilled out at a machine shop. He is open to suggestions and I was wondering some of you must have had this problem sometime in your biking career so what was the remedy? I have a KHS DJ50 if that is of any relevance.
Thanks for your time, I appreciate it
