Seatpost Adjustment

This is an easy one to forget, but can be costly. A seized seatpost can mean a significant amount of labor to get it unstuck. Simply attempt to adjust the seatpost, if it moves, you’re pretty much good to go. Take it one step further and see if the post appears to have any grease on it, or rust. If there’s grease, great, if there’s rust, inspect further. While you’re looking at the seatpost area, look at the seat tube clamp area and make sure there’s no weird buckling or cracking indicating an improperly sized seatpost is being used.

If the seatpost is stuck, it’s not the end of the world. Most times I can unstick a seatpost by applying Liquid Wrench a few times over the course of a day and then letting the bike sit for at least 24 hours.

I’ve only once had to hacksaw a seatpost out, but the technique did work. Basically you cut the post off 1/2″ above the frame, then using a hacksaw blade, saw through the wall of the seatpost from the inside of the post. You may have to make more than a few cuts as in this guy’s case.

Quill stems can also get stuck in the fork steer tube, I like to loosen and rotate the quill stem to make sure it’s not seized as well.
