  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.

    (clip)^^^^^^^^^^^^^ 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).
