Somebody has to have attempted this before, so I'll ask the question and see if they are on this list. I want to install a rear bike axle in a bottom bracket. I have a 14mm BMX axle, as well as a standard axle out of an old 12 speed mountain bike. I'd prefer to use the 14mm axle for strength. I'll put the races(cones) on backwards and I want to use the bottom bracket races. What sise ball set do I need to make this fit? bottom bracket bearings are too small
