    It was pretty ratty, bunch of us young wanna-be street racers who
    thought we could hold our own on the track. I was the worst driver
    out of our bunch, but pretty good with a wrench.
    SCCA Class -B- Production, SF region.
    Expensive for us young guys.

    Then got into bicycle racing, much cheaper and easier to maintain.

    Now I'm just an oldie who sometimes likes to mix it up with some of
    the young ones on the climbs with a steel frame bike.

    Looking at the design, we have a thin hard aluminum tube with a punched
    bottle mount

    Right in the maximum of tension load on the entire pipe, too.

    just opposite a loaded flange welded in the thin section.
    What was the question again? A whole 60 days, huh?

    I'm impressed that the top tube broke in *two* places rather than one
    after the downtube finally snapped. There's clear evidence of long-term
    crack propagation in the DT break. I wouldn't ride one of these things
    again without checking for cracks around that bottleholder hole regularly.

    Your computer's hardware is probably made in Taiwan. Possibly China. And
    I'll bet the hardware's been pretty reliable. That's as far as I'm going.

    Mike makes a good point. Free China (ROC Taiwan) can indeed do top
    quality work. And does.

    Nobody anywhere claimed otherwise, though. He was the first one to mention
    the place of manufacture.

    1. that bike is not 60 days old.
    2. tubes don't fail in multiple locations "jra". once something is

    what do i think? you bought an old used bike. it cracked, and you got
    mad, deliberately breaking it in other locations.

    I _know_ that there is a double letter in there someplace.
    Can never remember how to spel it.

    I've often thought that, if we want computers to actually make us smarter
    in
    any reasonable way, the spell checker ought to spit out a report at the end
    of each week or month showing words that were most-frequently mispelled
    (er.
    ok, misspelled). It's pretty amazing that's not already a normal feature.
    It
    would certainly help me a lot. That would give me a reason to actually use
    a
    spell-checker.

    Oh, if you want to be _serious_ about it, some applications
    have an unobtrusive but obvious way of highlighting words
    that it does not recognize. This way we do not need to run
    the spell checker as a separate process.

    It's offered as an OS-level service, available to any application whose
    developer uses the API, on the Mac OS. I am moderately sure this is also
    true on the Windows side, though I would have to look it up, and I'm not
    going to.

    The big news in Mac OS 10.5 was the availability of the grammar checker
    as well.

    And continuing tidying up the loose threads in this, er, thread, nobody
    has mentioned the Jaguar S-Type, which shares a common platform with the
    now-defunct Lincoln LS.

    The super-duper grand touring XK model shared a platform with the Aston
    Martin DB7 until 2006 or so, but I don't know if the DB and XK continue
    on a common platform today.

    The super-duper sedan, the XJ, gets an unshared chassis, but like the
    other models, pulls engines from Ford's common pool (notably the
    gets-around-like-crazy modular V8) and Jag-ifies them in various ways.

    The new Jags are great cars in their various ways, and surely far better
    than the dubious rolling bathtubs of trouble that were their ancestors.
    But one worries that every one of them offers about half the grins per
    dollar of a Mazdaspeed 6, which has the advantage of looking like every
    other unprepossessing Japanese family sedan, thus flying under the radar
    (so to speak).

    Alas, the wagon is not available in the US, and the Mazdaspeed 6 is not
    sold in Canada at all.

    Back to the bike that started this, I can't wait to hear how the
    warranty claim turns out, but that looks pretty impressive.

    I have the reciept from PerformanceBike in hand. It was purchased on August
    30, 2007 and ridden 2 -3 hours every Sunday until it died on Nov 4.

    Do you want me to scan in the reciept for you? Would that convince you?

    I guess it started with the seattube cradle breaking (note bit(s)
    missing inhttp://www.cs.utexas.edu/~jss/canaan/broken5.jpg) This caused
    to much movement in the main traingle with the crack in the downtube
    starting at the bottleboss. Once the crack was big enough to tear the
    tube with a gross overload the whole bike fell apart

    Hard to figure the order in which the breaks happened, but good eye.
    Don't think I've seen quite that kind of break before, especially
    without cracking the other left side as well. How do you think that
    happened?

    /s

    If you zoom in on picture1.jpg you'll see the same broken right side as on
    the left in picture5.jpg ... that's why I only took a closeup in
    picture5.jpg

    I guess it started with the seattube cradle breaking (note bit(s)
    missing inhttp://www.cs.utexas.edu/~jss/canaan/broken5.jpg) This caused
    to much movement in the main traingle with the crack in the downtube
    starting at the bottleboss. Once the crack was big enough to tear the
    tube with a gross overload the whole bike fell apart

    Hard to figure the order in which the breaks happened, but good eye.
    Don't think I've seen quite that kind of break before, especially
    without cracking the other left side as well. How do you think that
    happened?

    If you zoom in on picture1.jpg you'll see the same broken right side as on
    the left in picture5.jpg ... that's why I only took a closeup in
    picture5.jpg

    I was riding my nearly new (less than 60 days old) Canaan Elite and it
    exploded on me

    I could have been KILLED!

    I was riding down a steep hill and just at the bottom when all my weight
    was forced onto the bicycle and it exploded. I obviously crashed and was
    incredibly lucky not to be seriously injured. My helmet was also
    destroyed saving my head from a similar fate.

    I know that there is a warranty that could replace bike, but at this
    point I'm scared that it could happen again with the new bike and I could
    break my neck and DIE!

    Do you bike experts think this is fluke or do you think it could happen
    again?

    Looking at the design, we have a thin hard aluminum tube with a punched
    bottle mount just opposite a loaded flange welded in the thin section.
    What was the question again? A whole 60 days, huh?

    This is a GREAT answer and just what I was looking for.

    I guess you can say that I'm not 100% Satisfied with my purchase and I'll be
    opting for the a full refund instead of a replacement.

    I just got back from my local Giant dealer and I'm thinking I'll replace
    this Mongoose with a Trance 1. I hope the Giant holds up better.
