BEARINGS: ENDURO ANGULAR CONTACT 440C STAINLESS STEEL RACES AND GRADE 5 BALLS. ABEC 5 RATED.
ALLOWS THE USE OF SHIMANO HT2 (DURA ACE, ULTEGRA, 105, ETC.) OUTBOARD CRANK SETS
ON FRAMES WITH THE "BB30" STANDARD.
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.

-Works with Felt F1, F2, Z1 "stepped" carbon BB shells
At RWC, we have paired the machining precision of KCNC with Enduro Bearings to bring you the best BB30 to HT2 adapters available. 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.
For road applications, frames with BB30 x 68mm bottom bracket shells can now run HT2 road cranks (Dura Ace, Ultegra, 105, etc.)
To properly tighten these threaded bearing cups, two Hollowtech II compatible tools will be required.
KCNC recommends tightening the cups to 25 Nm (220 inch-lbs) of torque.
