    I would add one, would minimize the risk of the bearings sitting in water.

    Consult your Chinese carbon owners manual.
    Rigid SS 29er
    SS 29+
    Fat Lefty
    SS cyclocross
    Full Sus 29er (Yuck)

    Stop asking how much it weighs and just go ride it.

    This must be one of those Chinese "desert" frames. DO NOT EXPOSE IT TO WATER - IT WILL MELT!

    I ride in the rain often and water makes its way down the seat tube and into the bb. I'm not just a fair weather rider..I'm drillin that hole..

    Why would I need an owners manual when I have the fine people here to guide me..
