So part of my christmas bonus went to a new crankset and bottom bracket. The problem now is that i am having trouble determining the bottom bracket size on my XL Karate Monkey.

I am runing Shimano Deore XT components.
My new crankset will me a shimano deore xt M752.
Now I know that this requires an ES71 bottom bracket and that the bottom bracket width is 73.
What I dont know is how to determine spindle length. I have been looking on the internet and that has only confused me more. Let's just assume that I can not remove my current bottom bracket to measure that. Does anyone have any advice as to the 113 or 118.

Thank you and may your stockings be filled with bike parts.

I use the 118 for SS middle ring install w/ bashring on the outside. It really needs to be 122 or so for a straight run back to the freewheel.

I'm pretty sure that the 113 will work best for the triple in front. Either one would probably work w/o issue.
