I know this isn't the metallurgy mailing list, but this is a common enough myth in our world to be worth a swift debunking.
Ti (CP) can be as weak as 50 ksi yield or less, steel can be over 250 ksi. Even the strongest Ti alloys are not as strong as the strongest steels.
What Ti has a lot of is strength to density ratio, useful for lightweight structures. I like Ti; I made a lot of Ti frames. But those Ti axles are probably CP and almost certainly weaker than the best steel axles, and the Ti used in bike tubing is weaker than the best steel used in bike tubing. Ti frames are usually stronger, but that's due to larger tube diameters, made possible by the lower density.
