  1. hello,

    I am fairly new to cycling, and am looking to build a cyclocross with
    versatile components (ie, a triple + a 11/32T cassette). i have been
    considering a new bianchi axis, however a recent gift has changed
    things.

    i was recently *given* a poccianti titanium italian frame, hand made
    in some small shop in florence. it it beautiful, however it needs
    some work. both the top tube and the down tube have significant
    impact dents... such that they may need cutting out & replacing.
    also, 1 of the chain stays is bent. must of been in a car crash, not
    sure of the history. everything else on the frame looks solid... all
    of the welds, joints, etc....

    I am not at all familiar with this brand of frame, with titanium frame
    repair, nor do I have any idea what repair costs may be, or if this is
    even a good frame to build a cyclocross bike ... totally blind here.
    so a few questions:

    = how expensive is ti frame repair?

    = to build a cyclocross, what good quality but affordable components
    would you recommend with this frame (wanting a triple + a 11/32T
    cassette?)... I've been looking at the campy centaur, but I don't
    think I can do a 11/32T cassette... what else is possible?

    = and has ANYONE ever heard of a "sesto fiorentino poccianti"
    titanium frame?

    oh, lastly... if I go for it and build this bike, who sells (online)
    the best priced new and used component groups?

    clearly I am a novice, and I will be grateful for any recommends or
    input.

    ^^^^^^^^^^^^^
    Welding titanium is very critical. It must be done with shielding gas (TIG
    welded) and the inside of the frame must be purged with the shielding gas to
    remove the air. I would not trust this to anyone not familiar with titanium
    welding AND bicycle frames. I suggest you post to Sci.engr.joining.welding,
    where you are most likely to reach people who know. If you can elicit a
    response from Ernie Leimkuhler you will be well off.

    With three tubes bent like that it's almost certain to cost more than
    an equivalent new frame (unless it's a VERY expensive ti frame - I'm
    not familiar with Poccianti).
