Praxis M30 T47 Inboard Bottom Bracket
The Praxis M30 T47 Inboard Bottom Bracket is a T47 bottom bracket designed for Praxis M30 spindles. The M30 spindle has a tapered 30 mm drive side and 28 mm non-drive side diameter. This bottom bracket is available with steel or ceramic bearings and uses machined heat-treated aluminum cups. It is made for frames that can accept a T47 inboard bottom bracket, meaning the bearings sit within the frame.
This bottom bracket requires one Praxis M30 Bottom Bracket Socket Tool for installation and removal.
