BB Type (Acreditted to Terrible One's Website)
There are 4 types of BB's used in BMX and they are:
US - Was the industry standard for many decades has the largest diameter BB shell and the bearing cups are pressed in with the bearings poping into the bearing cups. The heaviest of the BB options but by far the strongest in terms of allowing the biggest possible bearings to be used. Recommended if you want a hassle free BB setup and you ride hard.
Mid - Quickly becoming the new industry standard, does away with the BB cups found in the US BB but uses the same size bearings that press-fit directy into the BB shell. As strong as the US BB but 1/3 of the weight recommended for any type of riding. The only downsides are that if your BB shell is deformed in any way wil most likely rendor your frame useless and they are only compatable with 19mm axles.
Spanish - Essentialy the same press-fit as Mid BB's but smaller in diameter but are avaliable in 2 sizes for:
19mm axles
22mm axles
Euro - The smallest diameter BB shell has a thread cut into itand you screw your BB into the BB shell. Has very small bearings which can be subseptable to wearing and crushing over a short period but this is a very light option recommended for light street, park trais and racing.
