Cycling Ceramic T47-IN Bottom Bracket PF30 86.5mm 30mm

This CyclingCeramic bottom bracket is designed to fit a PF30-type crankset with a 30 mm spindle into a frame featuring an 86.5 mm-wide threaded T47 bottom-bracket shell. The internal-cup construction positions the ceramic bearings within the wider frame shell, distinguishing this model from the 68 mm T47 external-cup and asymmetric T47A versions. It serves as a replacement for a worn or contaminated bottom bracket when rough rotation, bearing noise, or unwanted crank play is impacting the drivetrain. Before placing your order, ensure you check the threaded T47 frame interface, shell width, crank-spindle diameter, and available spindle length, as not every 30 mm crank provides adequate clearance for every wide-shell configuration. Installation requires the appropriate T47 tool, properly prepared frame threads, suitable assembly compound, and precise adjustment of the crank spacers and bearing preload.

- For threaded T47 bottom-bracket shells measuring 86.5 mm wide
