I have a BMX bike with some decent cranks on it laying around. They would be a improvement over what I have on my single speed currently.
They would be similar to this ~~>

I do not know much about BMX mechanics and size but I know that bottom brackets come in euro and american sizes. The bike I would take these cranks off of has a american shell. So would I just take the cranks and spindle and find a euro shell? or??
