Bmx Bottom Bracket Question


Matt Vandart

Recommended Posts

USA = Massive, mainly unsealed but you can get sealed

Mid = Mid sized whistling.gif

Spanish = Small i belive that the new Echo Push fit BB are spanish, might be wrong though.

Euro = Smallest, Usually screw in, but you can get push fit. Common in most modern mountain bikes.

With BMX there are two common different crank axle sizes 19mm 22mm. I have always rode 19mm just because 22mm seem to only be Odyssey and Primo now.

If you need pictures i can show you the difference between mid and spanish. I also have an Eclat CNC bb for-sale in 19mm if you are interested. Pm me.
