    Idea!

    47x16 will be almost exactly the same gear, and your wheel should be in almost exactly the same position in your drop outs. You will need to shorten your chain.

    C'mon, 7th grade math:

    50/17=X/16

    Now we're going back to 3rd grade... rounding numbers!

    But seriously, a 42 year old should be able to do simple math.
