    What width BB?

    What bottom bracket do I need for this crank: http://www.outsideoutfitters.com/ps-...-crankset.aspx
    I realize it should be a Powerspline type, but there are several widths. I need it for a regular EN 68BB.

    OK- you have a choice of 108, 113, and 118mm BB spindle lengths: http://www.universalcycles.com/shopp...3&category=346

    I would guess that 108mm would be best if you were going to use a single chainring, 113mm if you had a double, and 118mm if it were a triple. All of that would depend on the exact application- some frames might allow for shorter, some frames might require longer.

    Thanks.
    So I understand that for this crank here I should buy a 113mm BB.
