What would break first?

If well over-torqued, what would break/crack first?

(1) A carbon seatpost?
(2) The metal seatpost collar?
(3) The collar bolt?
(4) The carbon frame?

I was once told it would be the collar by my LBS, but that was in respect of an aluminium frame.

Thoughts?

  • I'd guess the frame. But that's all it is - a guess.

    May I ask why? Do you intend to overtighten your seatpost?

    Too many variables to say but you should never need to find out. Just don't over tighten it.

    In my experience not the bolt or collar, but probably the seatpost - the frame has a slot to allow for tightening. Get it torqued correctly and no need to find out!
    Make mine an Italian, with Campagnolo on the side..

    I would say the thread in the seat collar unless it has a steel insert then it would be the bolt that shears off. Let us know what you discover :wink:

  • For me it has been the threaded seatpost collars.
    (campy and others)

    Here's a tip: get the right sized bolt.
    If it's too short, you'll strip something. Duh. :oops:
