The KCNC PF30 adaptor is an extremely versatile bottom bracket. It allows KCNC (25 mm axle diameter) as well as Shimano HT II (24 mm axle diameter) cranksets to be installed on road bikes or MTBs with PF30 frames (46 mm inner diameter). This is achieved with the help of included spacers.
The high-quality bottom bracket consists of center threaded, CNC machined bearing cups and sealed stainless steel bearings for a long-lasting durability.
