Sakae SA Bottom Bracket
 

So I picked up a Sakae SA crank today to use on a budget road bike build I'm working on. I'm using a Nashbar aluminum road frame and next I need a bottom bracket. I'm hopelessly lost trying to figure out what size I need. I know it need's to be square taper, but I don't know what spindle length is right. Is there anyone familiar with this crank that could help me out?
