    Cold welding a CF tube?

    Can this threatening separation of FD braze-on on a CF tube be fixed?
    It is still holding, but I expect it to break sooner or later. Should I wait for it to break or maybe try to squeeze some JBweld into the crack (and pray like hell?)

    If it were my bike, I would:

    Drill out the rivets
    Find an appropriate epoxy
    Prep mating surfaces
    Apply epoxy
    Re-rivet

    If it wasn't my bike, I would consult the manufacturer and see if it's covered under warranty.

    Thanks, that looks like sound advice.
    I also think that two in line rivets only is not adequate for the leverage the cable pull has. The better braze-ons I see have four rivets in a square pattern, but I am afraid the bracket is too small for that.

    PS.: Come to think of it, it should be possible to buy a boss that can accommodate more than two rivets, shouldn't it? Do you know a source where I could get one?
