centerlock to 6-bolt adapter kit (pair)For internal spline lockrings only. Sold as a pair. Lockrings available separately. Our lightweight 6 bolt adapters make it easy to run your existing 6 bolt rotors with our centerlock hubs while preserving the ability to run centerlock in the future (not possible with 6 bolt hubs). System weight is similar to a native 6 bolt setup, as the inherently lighter weight of centerlock hubs and the elimination of bolts offsets the ~16g weight of each adapter.
