Can't get seatpost unstuck!
The seatpost on my Specialized Hardrock is stuck real tight in position. I've only had this bike for a few years, and it's stuck real good. I had a bike for 12 years that had a stuck seatpost and I was able to free it with one application of WD40. But with this Hardrock, I've used WD40 repeatedly and it did no good. Then I took someone's advice and used Liquid Wrench repeatedly, and it hasn't helped either. I've even removed one of the accessory bolts from the seattube and turned the bike upside down and sprayed Liquid Wrench into it so that it get to the seattube from the inside. I've also taken off the seat and put a wood block on top of the post and whacked it really hard many times to try to break it free. Still no luck. Is there anything else that can be done. Would a bike shop even be able to fix this?
