Engineers - Are seatpost shims frame-friendly??

[ovlov440]

stupid question, but if a seat-tube is butted surely whether you use a shim or not the post/shim will only touch the walls of the seat-tube for a relatively short distance anyway?

Did you ever find the Titanio you were looking for Woz?

Wow, that's some moons ago....I did, but always looking for another. PM me the details.

Yep - assuming internally butted.

Not a stupid question at all

My Marin is externally butted so no problem

My Ti frame has a welded in shim - the USE shim that goes in the frame to, is longer than the Ti frame insert.

That plug on the end of the post is a great idea, but wouldn't suit a internally butted frame or my Ti frame :-(
