RockyMounts 10810 DriveShaft Thru Axle Adapter is the first thru axle adapter on the market equipped with a keyed locking device. The Drive Shaft has a unique feature that allows it to easily convert from 15mm to 20mm by simply inserting plastic sleeves. The wide mouth cam lever design acts like a quick release for easy loading and provides a strong secure grip on the bike. The Drive Shaft fits most standard roof top bike racks, as well as Rocky Mounts, Yakima, and Thule. Locks and keys are included.
