The "scrutiny" reveals that no data was provided which supports the claim of heat-induced deformation. So the claim that someone claimed that bikes deform in hot garages has been fully supported by the "data," while the claim itself is completely unsupported by any "data."
So ... unless someone can provide information about bikes which actually have deformed in a hot or cold garage ... the claim is unsupported, and given the heat ranges possibly ... pretty ridiculous.
I don't see temps anywhere above about 115 even in Death Valley or the bottom of the Grand Canyon ... and I didn't see any garages in either locale ... and about the same maybe in Arizona/New Mexico ... Florida doesn't get that hot .... so maybe a garage might hit 140?
If you think 140 degrees is going to deform bikes ... okay.
Say ... wouldn't we be hearing about cars, lawnmowers, etc deforming also? Odd ... seems not to be the case.
I am sorry, but the idea that bikes or much of anything else except wax candles are going to deform in a a garage is pretty ridiculous.
Of course, if someone can supply a bunch of info showing i am wrong, I will admit I was wrong. that's fine.
Go ahead.

Okay: I have a 16 year old CF bike. It's been in its garage that whole 16 years, except when being ridden. It isn't warped.
There. Those are the data you requested.
Wait, you say that ONE bike in ONE garage isn't enough to prove that it couldn't happen? No ****.
Here's how you disprove the hypothesis: You determine the conditions under which it WILL permanently deform, and determine whether those conditions would ever be met in any garage.

As I see it ... only proven climate-caused deformation proves the point. No matter how many bikes didn't warp ... Only proof that bikes Did warp, and warped due to the heat or the range of temperatures, would prove the initial claim.
Disproving the claim is unnecessary. Even addressing the claim until it is supported is unnecessary. i can claim anything and then claim that you cannot prove the negative ... it is just hot air. An unsupported claim is nonsense. No need to disprove something wholly unsupported.
Hey .... let's drop this. This could easily develop into one of those drains down which whole threads get sucked. let's head this one off.
Barring further Concrete, Verifiable evidence of bikes warping due to being in garages ... let's just drop the whole topic. No more attacks, no more defenses ... just put it down and walk away.
Isn't this a thread about titanium bike frames?

Yeah, that one bike turned into a riding mower ..... hate it when that happens.

Good suggestions here. I would add that you should give the derailleur hanger a close look.
Most - if not all - titanium builds do not utilize a replaceable hanger.
Also, pay close attention to the fork - typically carbon fiber.
Litespeed frames are incredibly sturdy, so any sort of head-on collision exposes the fork as the weak point.
My '94 Merlin will accept a 28 rear tire; possibly a 32, but I have yet to try.
And, thankfully, it came with a threaded bottom bracket shell. Avoid their pre-'94 pressfit!

Relax. I should have said most vintage titanium did not come with a replaceable hanger.
So you sound a little off by saying "only lower end..." This is a discussion about a vintage Litespeed, afterall.
Unsure if Litespeed, Merlin, Seven, Moots, Holland, et al ever began using a replaceable hanger.
Well, those are all low-end, according to you.

But this is a discussion about used Ti frames, not necessarily vintage unless you consider less than 20 years ago vintage. Just about everything since 2000 except for budget bikes have had replaceable hangers.
