Bike fork mount for 15mm or 20mm thru axle

I've seen multiple threads where people have asked about fork mounts for their 15mm and 20mm thru axle forks. Kuat sells fork mounts for all three standards. I'm using the Yakima Blockhead for my 9mm forks, but will be getting one of these when I convert to a thru axle on my 29er.

Welcome to TW

 

The Rocky Mounts DriveShaft is a little pricey, but looks solid. I lock my bikes with a heavy cable, so I've been using non-locking fork mounts.

Do you have any tips on singletrack in NC? I'm going to be in the Asheville/Black Mountain area next summer. I rode in Pisgah a couple years ago. Any trails you recommend over towards Boone?
