Having trouble figuring this out.

So I think that most track cranksets are 110mm and less, right? So I could just order a 107mm BB from Velo Orange and not have to worry about it?

I was reading up on ways to do this for cheap, and one of them was basically to hunt down some french threaded cups and use an asian/square tapered spindle (like this one http://aebike.com/product/sugino-sg-...r4076-qc30.htm) However that spindle is nearly the same price. I know that I could always do some searching, but I think that would probably be a cheaper solution.

I am just tyring to figure out the right crankset and then the appropriate BB spindle length. Is it wrong to use something larger than 110mm? And what exactly is the right crankset I should be going for?

Oh man, so many questions.
