i am getting a banshee amp frame, which takes a 73mm bb, so i am planning on getting a saint bb from crc, 73mm obviously. it says that it takes a 24mm inner diameter axel or spline, and to my knowledge a bmx spline is 22mm? so my question is, can i fit my bmx cranks and spline into this bb? if not, what alternative bb can i run as i want to keep the cranks. Also the bb shell on the Amp is threaded, so i assume normal bmx bb's will not work? cheers for the helping hand!
