    What's up with the Cdale welds??

    I just got a 2003 Jekyll 1000 and I am really pleased with it. I'm curious though, what is the deal with the welds being so smooth--no other bike i've seen has anything like them. Are they a ground down TIG weld, or are they filet brased?

    Further, what's the advantage other than asthetics?

    Filled and sanded, I think.

    The advantage is asthetics, as far as I know.

    Cannondale will tell you that there is a strength advantage as well. The main cause of frame breakage is weld failure due to an imperfection (small gap, etc). C-dale starts out with very oversized welds that not only use more material, but also extend a bit further up the tubes, and then sand 'em down for aesthetics. They claim it makes for a stronger weld.

    Friends of mine who weld and have taken courses in welding say there is no strength advantage. Beaded welds and smooth welds should be equally strong if done perfectly. A good, strong weld should go all the way through the material being welded. A beaded weld is not a series of individual welds as it looks on the outside. It is actually a continuous weld where the "puddle" gets pushed back into itself at regular intervals.
    Cannondale's real claim to fame is thier "tab and slot" system for fitting tubes together before welding, and all their tubes are precisely cut with a laser.
