I'm in the process of moving parts between 3 Bromptons, two Titanium and one steel, and figuring do I sell/keep a Titanium-based bike for long day rides. I'm not bothered about weight or rust, but on speed and comfort.

I've read Sheldon's muse that Ti is springier and that on areas like curved forks it will make things a little comfier, and on rigid triangles it has no performance impact, but what's anyone's view on this?

I can make a touring-specification Brompton which is a S6R with SRAM rear hub and Sclumpf Mountain Drive, and make the forks, rear triangle and the seatpost either Steel or Titanium, in fact I can pick Ti/steel for each of these 3 components separately (e.g. Ti forks, steel triangle, steel seatpost). I'll sell what I don't want. I don't need 3 Bromptons, this is a matter of do I sell/keep Ti.

Views?
