I'm looking on possibly buying a Nicolai BMXTB frame, but I want to install BMX cranks (Profile or Odyssey)... what kind of Bottom Braket is needed for these kind of mtb frames? Euro maybe? 19mm or 22mm?
thanks

Euro BB is what you're looking for.

Profile uses a 3/4" spindle, so you have to get a BB made for them. Oddyssey has cranks out with a couple different size spindles. 19 and 22 mm are the most common sizes.
