Praxis Works has been making precision MTB parts for years and they have a reputation for uncompromising quality standards and products that just work. The M30 crank spindle standard is exclusive to Praxis and is unique as it provides a 30mm ID drive-side bearing and a 28mm non-drive bearing.

The Praxis M30 PF30 bottom bracket allows you to fit a set of M30 cranks into your MTB that has a BB30 (42mm diameter) or PF30 (46mm diameter) 73mm-wide bottom bracket shell.

The ABEC5 sealed cartridge bearings are housed in heat-treated and machined aluminium bearing cups and the bearings are pre-loaded with a wave washer on the drive side.

Style: Thread Together Shell. Non-drive side cup is pressed in and the drive side cup threads into it for a secure and creak-free fit. A larger intermittent sleeve (included) is used to reduce your PF30 shell to 42mm for use on such frames.
