Cycling Ceramic T47A Bottom Bracket PF30 Ø30mm 77mm

This CyclingCeramic bottom bracket is expertly crafted to accommodate a crankset with a 30 mm spindle, designed specifically for frames utilizing the asymmetric T47A threaded standard and a 77 mm-wide bottom-bracket shell. The T47A configuration features distinct cup positions on the drive and non-drive sides, distinguishing it from conventional PF30 press-fit frames or symmetrical T47 shells. Its premium ceramic bearings make it an ideal choice for replacing a bottom bracket that has begun to exhibit rough rotation, bearing noise, or lateral play. Before placing your order, please verify the frame’s T47A interface, the 77 mm shell width, and the crank’s full-length 30 mm spindle, as SRAM DUB, GXP, and Shimano 24 mm cranksets necessitate different bearing dimensions. Installation requires the appropriate T47 cup tool, clean frame threads, a suitable assembly compound, and precise tightening, followed by correct crank spacing and preload adjustment.
