The M30 bottom bracket family is for the Praxis M30 spindle based cranks. The M30 spindles are 30mm and then have a step-down to 28mm to lock on the Non Drive bearing. These use a drive side wave-washer for the bearing preload, and a 30MM Drive bearing with a step down to 28MM Non Drive bearing. The Zayante, Alba, Girder and Cadet all use the Praxis M30 bottom bracket.

Please contact us if you need help figuring out which bottom bracket you need to suit your frame.
