How durable is Ti frame?(5 posts)

How durable is Ti frame?rengaracchi

IF claims that welding causes molecular level structural changes in Ti that could cause micro-cracks over time. I wonder how serious this problem could be in real life situations over the period of, say, 15-20 years? IF "shot peens" their Ti frames to cancel out the structural change, and due to this extra process, their Ti frames are very pricy. At the same time, Ti becomes more common, and you can buy fairly modestly priced Ti frames everywhere. I was considering buying a Ti frame but I bought steel frame in the end partly because of this micro-crack concern. Steel is time tested, and I like the feel of it ;-). Does anyone have a good idea about this?

Thank you.

But it really is bogus relative to bike frame failure. The "little guys" want us to believe (and many of us do) that their welds are somehow superior to the big guys' product. The facts are that LS has been putting out Ti frames just as long as IF (and its predecessors) and have not hade any significant problems attributable to welding. LS has been welding Ti for a couple of decades, at least - they started as a machine shop with Ti expertise for aerospace, and got into bikes when the cold war wound down. IF's claim has no relevance to the durability of their Ti frames vs. the other quality builders.

Litespeed has a lifetime warrenty. What else do you need?
That is just a bunch of IFLazywriter

Bullsh#$ marketing. I assure you that any well made and welded ti frame will outlive you and I under normal use. If a ti frame doesn't break at the welds within a month of use, it should last forever.

Any well built Ti Frame will outlive the buyer barring accident or abuse. Any well built steel frame too, for that matter.

That said, IF makes exceptionally beautiful bikes. I wouldn't mind having a Crown Jewel at all, and if I could afford one I would.
