At RWC, we have paired the machining precision of KCNC with Enduro Bearings to bring you the best PF30 to GXP 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.
IN PROPERLY ADJUSTED ANGULAR CONTACT (A/C) CARTRIDGE BEARINGS, ALL OF THE BALL BEARINGS ARE ENGAGED AND SPREAD THE FORCE OVER A LARGER SURFACE AREA, DECREASING FRICTION, AND MINIMIZING WEAR. EXCESS PLAY CAN BE ADJUSTED OUT OF THE BOTTOM BRACKET WITHOUT THE USUAL RISK OF SIDE LOADING THE BEARINGS.
To properly tighten these threaded bearing cups, two Hollowtech II compatible tools will be required.
Tighten the cups to 35 Nm (300 inch-lbs) of torque.
