At RWC, we have paired the machining precision of KCNC with Enduro Bearings to bring you the best PF30 to HT2 adapters available. This Conversion Bottom Bracket works for both 68mm or 73mm wide PF30 shells. The KCNC design offers several advantages, including optimum bearing placement on the crank set spindle. The double O-ring seals on the "cups" ensure a positive, creak-free fit regardless of BB shell tolerance variations. Because the two halves thread together, when the bottom bracket is properly torqued, it becomes locked into place within the bottom bracket shell. The aluminum body does not flex or distort under load. This also forms a solid barrier from moisture that may be trapped in the bottom bracket shell.

Installation: To properly tighten these threaded bearing cups, two Hollowtech II compatible tools will be required. Tighten cups to 35 Nm (300 inch-lbs) of torque. Complete installation instructions included with Bottom Bracket
