    well then i suppose i am unfamiliar with the variables of sizing, this is the only size information i need to find an appropriate bottom bracket? do i need a certain spindle length, or casing length for it to fit properly?

    ive never changed a bottom bracket,

    The spindle length is dependent on the crank. What crank do you have?

    You read the website of the maker of your crank and find out what size and taper (JIS or ISO) spindle it needs.

    For instance, I use IRO cranks which take a 110mm JIS spindle.

    The bikes direct website lists the BB as 68x103, but I've had mine out and it's a 68x108 with the stock truativ cranks.

    If you're running something else you'll need a BB size specific to the cranks you have.

    it's normal standard track bike specs--- 42mm chainline with a properly dished 120 spaced track hub--- so most cranks made for ss/fg will tell you the right bb to use.
