Not sure, I didn't know there was a difference! I just bought a BB off of CRC!

Here's a little explanation of bottom bracket sizes...

USA BB - The old BMX standard. Uses large bearings which are pre-fitted into cups, which then press into the frame.
Mid BB - Uses same size bearings as USA BB but with no cups, instead they press directly into frame.
Spannish BB - Same idea as Mid BB but smaller bearings.
Euro BB = Threaded cups with pre-fitted bearings. These screw into the frame.

For your frame you deffo need a Euro BB.

Another thing to note is that bearing size will dictate what cranks you can use, or vise versa. The centre hole in BB bearings is usually either 19mm or 22mm, so you need to think what cranks you're going to buy to suit. Most cranks are 19mm axle so might be worth getting a 19mm Euro BB. Saying that, some BBs are 22mm but come with spacers / adaptors to allow use of 19mm cranks... so that might be something to consider too, cos then you can run any cranks (except the very few with 20mm axles).

Anything else you're unsure of post here and I'll try and help later today / tomorrow... I've built lots of BMXs from scratch and currently building my 2nd jump bike (between pay cheques like you!), so I totally feel your pain when it comes to differing sizes and standards!

should fit your frame, you will need one of these tools for the job though...

the American/Canadian equivalent is probably cheaper though
