    Strengths:    This Stem is extremely light, lighter than most carbon stems but strong and very functional

    Weaknesses:    None that I could find

    Bottom Line:   
    If you're looking for the lightest x-country stem that is attractive and 100% functional look no further. If you're looking for a downhill stem look elsewhere there are other more robust choices.

    Date Reviewed: March 3, 2011

    Strengths:    Very light, looks great, titanium hardware is sweet, comes in many different lengths to get right fit.

    Weaknesses:    Felt pretty flexy to me. Expensive if you get it RRP

    Bottom Line:   
    Awesome looking stem, looks beautiful and the attention to detail is very good. Felt flexy to me and made the front end of my bike feel a bit slopy.

    FSA OS-99 CSI Stem

    Does anyone roll with one? Any thoughts? Weights in at 118g, it will be paired with a K-Force XC Carbon Bar to bring the weight up to 306g. I haven't up graded shifters yet so I wont even go there.Read More »

    FSA OS-99 Stem pics

    Here are some low res stem pics. The FSA OS-99 90mm is 97 grams. I previously had the Bontrager Race X Lite, which claims 110 grams but was actually 137 with hardware.
