A Fignon fan here--isn't that the anti-weight weenie photo of all time? David Feldman

Yeah, but Ti often has a rather nasty habit of catastrophic fatigue failures, i.e. it snaps, whereas steel usually yields and slowly bends/sags.
Ask Laurent Fignon what he thinks of Campy SR BB spindles...!

They don't call it Titanium for nothing. Ti at ANY diameter will be stronger
than steel. The fact that they make submarine hulls out of the stuff is a
dead give away. Or better yet, the wing skeleton of a 747 is made from Ti
tubing. You can pick up a 50 ft section with a 8 inch diameter and wall
thickness 1.5mm, drop it from over your head: It won't even ding. Try do
that
with any steel alloy of the same configurations any day of the week. Cheers,
