you need the proper BB and because your BB has 73mm, you need one of these:

http://www.leafcycles.eu/products/cranks/euro-bb-spacer.html

it's a 73mm BB spacer, because the ones that usually come with BBs are for 68mm BBs,
(or you can put 5mm of spacers)

are so many brands making those BBs, do you know what cranks do you want? you can begin there to sort out the BBs you wont need.
Or better, what's the axle's diameter?

im hopefully buying some primo hollowbites with 22mm axle for my mtb, and im having a bit of confusion about the bb too. if my frame is a standard 68mm then if i bought a 22mm primo euro bb, would that fit fine? and if i had a 73mm then the normal euro bb but with that slightly longer spindle sleeve would do it?

I have bmx Profile cranks on my Blackmarket MOB. I had to buy a longer spindle (6") from the Profile website... and i got a euro bottom bracket (Odyssey) from empirebmx.com

It fits fine. I've had my Powerbites for 5 years now and haven't had any troubles. A slightly longer spindle would be ideal but the stock spindle still provides enough room for the crank arm to sit on safely.

That spindle sleeve isn't even necessary. After too many issues with bearing drag I tossed my BB spacer and haven't had any troubles since.
