Message: >Hi does anyone know if bottom brackets are a standard size or if there are different size and if theres is different sizes how do u find out the size of it. >Thanks They come in all different sizes for all different cranks. There are also a few that even have italian threads. I think first you should measure your bottom bracket shell; second, check the model of your crank to see what bottom bracket it uses; third, you could measure your old bottom bracket (there's often clue from the bottom bracket markings.
