That's backwards. The endurance limit is the stress below which the material could survive infinite cycles. Aluminum does not have an endurance limit, steel and titanium do.

Thanks for the correction. We agree on the concept: Al frames have a finite life (due to the properties of the metal)*.




*Depending on the design, the "finite" life for a given rider might be so long (ex. 50yrs) as to be irrelevant.

I have a 2012 lynskey Ti, it developed a crack in the head tube (head bearing installed sideways, my bad), got it repair by mr dekerf, its been perfect ever since.

Most Ti frames that were welded properly will last a lifetime.
Ride on my friend.

I still ride my 2006 Ghisallo especially in the mountains since it has regular wheels (HED Ardennes) and I like that braking feel. Plus it is my lightest road bike. I wish however it had Di2 versus SRAM Red
