I used to think a 10mm wrench was the only tool for a stuck seatpost
Had a steel frame with an aluminum post that was totally frozen... tried the usual tricks like heat and penetrating oil for a week with no luck. A guy at the shop in Boise told me to use a long piece of pipe as a lever on the saddle rails, not the post itself. I was sure it would just bend the rails, but after a slow, steady pull, the post came free on the third try. It turns out spreading the force out over the whole clamp area works way better than just twisting the post. Anyone else have a different trick for a really stuck one?

Wait, a 10mm wrench? That's for the seatpost bolt, right, not the post itself... I've always had to use a bigger wrench on the post for leverage, like a 14mm. The pipe trick on the rails is smart though, never thought of that. I've seen people try to twist the post with a big wrench and just round off the corners.

My old Trek had a 10mm bolt but the post itself was a weird 13mm. The real trick is checking if the post has a flat spot for a wrench before you even grab a tool.

I mean are we really overthinking this? Its just a seatpost, not brain surgery. I've pulled plenty of stuck posts with nothing but a pipe wrench and some elbow grease and never snapped a rail yet. @riverb13 I think you're giving people too much credit for being careful, most folks just grab whatever tool is closest and go for it. A 10mm vs 13mm confusion is way more common than people want to admit, but at the end of the day if you're not reefing on it like a gorilla itll be fine.

Yeah, the pipe trick works until the rails snap.
