    Caution;  Merge;  Workers Ahead! Bontrager race xxx lite 2010 opinions?

    Has anyone used the new 2010 bontrager race xxx lite stem?





    http://bontrager.com/model/08366

    Manufacturers claimed weights are:

    31.8mm Carbon / Clearcoat 90mm 7 113g
    31.8mm Carbon / Clearcoat 100mm 7 116g
    31.8mm Carbon / Clearcoat 105mm 7 119g


    Any information would be welcome. This is going on an Ibis Mojo SL, for XC and light Trail use.

    Thanks,


    Kevin

    Same weight as AL

    I have weighed this stem and it was within 10 grams of the aluminum RXL OS stem. If you add ti bolts to the RXL, it is within a few grams of the same weight. Quite a big price difference.
    The RXXXL looks cool and I would assume it is stiffer, but I have no complaints with the RXL.

    Causes the laminar airflow to become turbulent, like the dimples in a golf ball or a Zipp wheel?

    I think it's the part of the stem that angles down sharply. Looking at the other pictures, I can see the hard angle, in the second picture.
