    info on geometry of group buy IRO

    i did a search and its hard to find anything concrete. went to the IRO website which didnt say much.

    tubing is what?

    geometry is more like the angus or mark V?

    oversized/ovalized/angus style tubing?

    thanks

    let me rephrase. i went to the IRO website and found this:
    Dedacciai Heat Treated tubing.

    T/T:28.6x0.9x0.6x0.9

    S/T:29.6x1.2x0.6x0.9

    D/T:31.8x0.9x0.6x0.9

    S/S:16x0.6

    C/S:22.2x0.85x0.6x0.8

    can someone tell me what this means as far as tubing (what bike is it similar to), geometry, shape of individual tubes?

    They are round tubes. The first number is the tubing diameter. The following numbers are the tubing thicknesses. For example: the downtube is 31.8mm in diameter, and is double butted with thicknesses of .9 mm at the ends of the tubing and .6mm in the middle. It has the same geometry as the Angus.

    Which has the same geometry as the Angus.

    From the IRO site:
    The frameet will have the same geometry as the Mark V and Angus.

    Ok, last question before ordering one. Is this thing going to have water bottle mounts? Sorry, after the first 40 miles I get a little thirsty.

    The 21st is tomorrow so here's to an end to this thread finally! I swear I will not look at it again once I order one. Really!
    One gear, all the time.
