Truing a wheel with a Lefty hub is just the same as truing a standard wheel. It just requires a truing axle/adapter to mount it in a standard truing stand. Simply remove the wheel from the Lefty, remove the reverse-threaded axle cap on the hub, and insert Cannondale’s QCTL108. This axle cannot be used for riding or adapting hubs, it is meant solely for truing wheels.
