Bearing Size - most bottom brackets use 1/4" bearings, but there are some that use smaller sizes so it's advisable to measure your old ones or check with a local bike shop to be sure.

Retainer Type - you can use any type of retaining cage in any bottom bracket as long as the bearing sizes are correct.
