At RWC, we have paired the machining precision of KCNC with Enduro
Bearings to bring you the best BB30 to GXP 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 GXP road crank sets (Red, Force, Rival, etc.).
tighten these threaded bearing cups, two Hollowtech II compatible tools will be required. KCNC recommends tightening the
cups to 35 Nm (300 inch-lbs) of torque.
Use wave washer (supplied) on drive side spindle, between
crank spider and BB seal.
