Bottom Bracket sizing?

I have a trek 5200 frame that I have been slowly upgrading the components on. Most of the stuff is off Ebay so I have gotten some good deals over the past year or so. I have sort of hit the wall though at the bottom bracket since I don't know what size and thread to look for. Cah anyone tell me what fits this frame?

Thanks in advance

It's a 68mm shell with english threads. As far as bottom bracket spindle length goes you need to specify if you are building a double or a triple and whether you are going with inboard or outboard bearings.

As capwater noted, it's English threaded and has a 68 mm bb shell width. The spindle length and type (square taper, Octalink, ISIS or various external bearings) will depend on the crank you use. The crank manufacturer will specify the type and length.
