On special occasions, bike racks need an adapter to fit the trending fatty axle.
Older fork mounts only fit standard quick release bikes, this adapter allows you to carry your thru-axle fork on your current rack. RockyMounts DriveShaft is a 12/15mm/20mm thru axle adapter that can handle all three sizes of thru-axles and the only one on the market to lock up your bike. It fits standard fork mounts from RockyMounts, Yakima®, and Thule®. It's wide mouth opening creates easy loading, holds tight with adjustable cam lever, and comes with snap in nylon shims to prevent the axle from being unscrewed and gives the ability to switch from 12mm to 15mm to 20mm thru axles, just like that. Comes with RockyMounts locks and keys.
