The Praxis Works T47 Internal M30 Bottom Bracket-28/30mm Stepped Spindle is a precision-built option for running Praxis M30 cranks in a T47 road frame. Forged and machined heat-treated alloy cups pair with Enduro bearings and high-grade grease for smooth, dependable performance, while the stepped 30mm/28mm bearing setup matches the Praxis M30 spindle perfectly. A road-specific 85.5mm threaded shell width keeps the fit dialed for compatible frames.
