    should be ISO, but it's not too hard to check for yourself.

    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

    Look out for those Giant Iguanas... they'll bite your head off.

    A really rough, random guess is English thread, 118mm length spindle. Without knowing the exact crank model, it's hard to be more precise. The model name should be printed on the outer face of the crank, the model number is probably stamped on the inner face. The model number will be "FC-Mxxx". Fill in the blanks.
