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
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
KCNC recommends tightening the cups to 35 Nm (300 inch-lbs) of torque.
