A good idea that would make for easy work as long as you could isolate all of the fluid in the seat tube. What I could not overcome was how to stop all leaking into adjacent tubes and out of the frame itself. I used uninflated balloons stretched over either side of the BB shell which worked really well. It ran through the holes for the BB cable guide which I successfully plugged with chopsticks. Great. But then it found its way out the chain stays at the dropouts and out the headset, out the stem. Everything is open inside the frame to some degree. Then I flipped the frame, plugged the top of the seat tube and tried filling through the BB shell. Ultimately the same problem. It ended up getting so messy (and dangerous) that I had to stop. If it was just a matter of plugging the BB shell and fill the seat tube it would be a certain fix for all bikes. But you must have a bike with isolated tubing? I can't emphasize enough how gnarly this stuff is. Extreme caution required.

It's important to say that ALL vestiges of the caustic soda must be cleaned out of the seat tube before fitting your new seatpost. If you don't do this, the remnants of the old caustic soda will soon make the new post corrode into the seat tube. It happened to me!

I once had an aluminium paint spray pot and I thought it was a good idea to clean it with a caustic soda mix, so I put it on the floor in the garage and came back after a couple of hours and all that was left of the post was the rim and a small part of the top end.

I was expecting a volcano type explosion of caustic soda anytime. Please, if you attempt this, find a way to not loose your face. A weaker solution over a longer time comes to my mind.

Hi, thank you for the valuable insight! It's good of you to put more information out there. I'm curious, how does this shoe handle moisture? Does it keep the interior dry in wet conditions? On the flip side, do you find sweat building up inside during your runs?
@kingoffootball2 жыл бұрын
I have only run in these when it's been a bit damp and light rain, rather than really wet conditions, but my feet have stayed dry in those situations. They are reasonably breathable though, so my feet don't get especially sweaty, but I would expect any significant rain to go through.

Hello. Yes, it's a great frame. After removing the seatpost I had it powdercoated, built it up and rode it. I did eventually sell it, because I had two very similar frams, both from 1993, and I slightly prefer the other.

If the aluminum seatpost and aluminum frame are stuck, how do you remove it?
@kingoffootball2 жыл бұрын
That's certainly more difficult. Firstly, soaking it as much as possible in a dismantling lubricant like Plusgas is a good step. After that, if it is not sheared off then you can try to get it moving clamped in a vice, but otherwise I would try using a slide hammer, or as a last resort cutting it from the inside using a saw blade with a handle attached.

Different people seem to have had different experiences.

I think it is possible to do it without damaging the paint if you are careful.

@kingoffootball8 жыл бұрын
Carbon fibre is rated as having good resistance to sodium hydroxide (caustic soda) chomarat.com/wp-content/uploads/2011/06/CHO-3265-Chemical-Resistance-Guide.pdf but it is quite an extreme solution, so always best to make sure you've tried easier methods first. It would also be worth consulting an expert in carbon to back up the carbon's resistance as I am no expert. I rinsed the frame out and dried it afterwards, but so long as you use sufficient caustic soda all the aluminium alloy will have reacted away and the product tends to drain out pretty easily. Good luck with getting that post out.

Yeah, I sprayed some Waxoyl inside all the tubes just to help protect it once it was thoroughly dry. Not specifically because I'd used caustic soda on it, just because I would have done that to help protect the steel frame before I rebuilt it anyway.

Have a six pack of beer with you while doing this. Not to drink, but to splash on your body that might get hit with that caustic soda mix. Caustic soda will burn your skin very very quickly but the beer is at the opposite end of the pH scale (beer is somwewhat acidic) and will neutralize the nasty caustic and just might save your skin. Of course, any beer left over after finishing this project can then be consumed in celebration!!

@kingoffootball9 жыл бұрын
Is it definitely an aluminium seat post? If so and it's not really reacting then it's most likely to be the strength of the caustic soda solution. Dissolving the caustic soda is exothermic, so the solution should get quite hot - so if it's not heating up much maybe it's not strong enough. Best to be careful and start with a weaker solution anyway and then get more concentrated until it's effective.
@Lammy2k9 жыл бұрын
kingoffootball Hey man, thanks for getting back at me. I followed your adivice and spiced things up a bit. I bet the main reason was, that the soda did not stay in in place for a long time.
