The Praxis Works PF30 Bottom Bracket allows riders to use their Shimano Hollowtech II 24mm spindle cranks in a frame with a 73mm BB30/PF30 bottom bracket shell.

To do this, Praxis designed a specialised sleeve to compensate for the extra space and they are made precisely to Shimano bearing stance & chain line spec.

Who's this item for: These BB's are a great solution for anyone wanting to run their Hollowtech II cranks in a frame with a BB30 or PF30 bottom bracket shell.

Style: They use a thread-together design where one cup is pressed in and the other cup threads into it to lock everything into place.

Shell width: 73MM BB30/PF30 MTB frames only.

Spindle size (diameter): 24mm.

Bearing style: High-grade and full sealed Enduro 2437 steel bearings.

Bearing cup/shell material: Forged & machined heat-treated 7075 T6 Aluminium.

Weight: 149g +/- with included sleeve

Installation tools: Requires two standard 16-notch 44mm BB tools along with a press tool/drift for installation.
