At RWC, we have paired the machining precision of KCNC with Enduro Bearings to bring you the best BB30 to HT2 adapters available. This Conversion Bottom Bracket works for both 68mm or 73mm wide BB30 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.

For mountain applications, frames with BB30 x 68mm bottom bracket shells can now run HT2 mountain cranks (XTR, XT, SLX, etc.)

Equipped with Enduro "CH" Series ceramic hybrid angular contact bearings.
