Most aircraft mechanics have daily hands on experience with both high strength titanium and high strength steel fasteners and see that titanium is nothing special strength wise. Many Ti fasteners have lives limited to the single digits of cycles (re: 2009 crash of an S-92 off Newfoundland).

biketanium puts up some phoney "myths" (hardness, rust!?!) then debunks them by comparing high alloy Ti to low alloy steel. A fairer comparison would be against something like Aermet steel which is more than twice as strong as his Ti. The poor quality of his argument leads one to throw out the whole concept even though there are certainly valid applications justifying Ti fasteners (probably not on bikes).
