Testing the Nuclear Option for Seized Seatposts! (Shocking Result)

Описание: Is your seatpost truly seized, or just "stuck"? In this video, I take on two "impossible" cases: a £5 Saracen and a classic GT Tequesta. Both frames have been subjected to every trick in the book—blowtorches, Stilson wrenches, and endless cans of penetrating oil. The result? Completely ruined paint and zero movement.

I’ve decided to move past the DIY hacks and bring in the "Nuclear Option." I recently imported a professional-grade seatpost extraction machine from a frame builder in France. This isn't a hand tool; it’s an industrial jig designed to apply tons of vertical tension to break galvanic corrosion bonds that have become one with the frame.

What you’ll see in this video:

The Failure of "Hacks": Why boiling water, PB Blaster, and big hammers often do nothing for a true chemical bond.

The Industrial Reveal: Unboxing and setting up the V3 extraction jig—a beast of a tool!

Total Material Failure: Watch what happens when 5,000 lbs of force meets a seized aluminum post. Spoiler: The metal reaches its ultimate tensile strength and literally rips in half before the bond gives way where I foolishly drilled a hole in the post

This was a massive learning curve. I learned that drilling holes creates a "stress riser" that leads to tearing. In Part 2, we are going for a "pure" pull with no drilling.

🚨 PART 2: DONORS WANTED! (UK Midlands)
I have a machine that is officially stronger than the bikes themselves. Now I need fresh victims!

Do you have a frame with a seatpost or stem that has defeated every professional shop?

Are you in the Midlands area and willing to donate a "doomed" frame for science?
