OK. It appears that people need to take a pill. I never thought that the smiley face emoticon was THAT necessary, but apparently it was.
Here's the deal. I've seen a lot of creaky Ti bikes in the last couple of years. And as I understand it, it takes a bit of care to get a BB properly installed in a Ti frame so that it doesn't work loose and creak, and it wants more regular looking after--like more so than aluminum or steel, which also want looking after. Not a bad thing, just a thing. I've seen more creaky ones than not, so...blah blah blah.
As to more Ti bikes than fast guys, I wasn't trying to impugn the honor of anybody here. I'm not even sure what I meant anymore, but I can assure you it wasn't a dig on any of the posters in this thread.
It's all a joke. Maybe not a good one, but not exactly something to wad panties over, either. I would think Alienator, as one of the most frequent receivers known to me of the "lighten up, it's a joke" treatment, would have figured that out. Guess not. Of course, he didn't figure out anything helpful for 96gators' problem either, I noticed. And 96gators? You probably shouldn't be taking your reaction cues from Alienator. It'll make you seem, um, let's say "over-sensitive." And now it definitely ain't rain you're feelin'.
You want helpful? Here: Check the torque on the BB installation, as well as the torque on whatever retainer your cranks use. If they're OK, you might consider teflon tape on the BB threads. I've heard that's helpful in Ti BB installations--though I could be wrong. You should also take seriously the suggestion that it's some other part of your drivetrain that's gone loose, including but not limited to your cassette lockring and your spokes. Normal frame flex does not typically result in creaking, and it seems unlikely that you've already so fatigued the frame that you've lost appreciable stiffness (unless you're a big guy and a major masher) so you can probably concern yourself with flex last.
