How much have you paid for gearing components (chainrings, cassettes, hubs, derailleurs, etc.)?

    I have a trike, shifting gears is a big problem. to the point in breaks the rear derailer,
    can this be setup to shift on both the front and rear at the same time. lowering one while raising the other?
    please contact me as I need this if it will work my way....
