I've used this now for about a month. It does the job better than any other adapter I'm aware of. I have a Salsa Bucksaw Carbon with a RockShox BLUTO front fork held onto a Yakima roof rack. The clamp pinches the front axel tightly, so the through-axel cannot be turned or fork slid to one side when clamped down. The adapter mount can be quickly popped off and moved to another vehicle if you unlock the Yakima quick release and lift upward. Additional security can be achieved by sliding the Yakima skewer THROUGH the holes in the adapter and NOT using the drop-out style end on the adapter.

Although you need only unlock the adapter to remove the bicycle, You'll need to carry TWO keys if you use the Yakima SKS or similar key system already. No manufacturer has lock cores that are interchangeable or comparable with another. Not a big deal perhaps, but I'd happily pay $25 EXTRA for a Yakima key compatible adapter. But then, I hate keys. Your mileage may vary. ;-)

First off, when working correctly this thing is great. My only complaint about the overall design is that it stands pretty tall and so raises the height of the front of the bike about 4-5 inches. As received though the shims for use with 15mm axle would not snap into place due to powder coating build up on clamp assembly. From a design standpoint they have attempted what's called a "double reference" which is a big no-no and is guaranteed to be a problem especially with powder coating where the thickness cannot be controlled. In this case, and I suspect many others, the parts would not go together. On the positive side, I contacted Rocky Mounts and they sent out a replacement the same day with return label for the bad one. They even installed the matching key lock mech for my current Thule rig. So for customer service they get 5 stars but for engineering they get 2.5.
I would have given it 5 stars, however I had to modify it by hacksawing off the bottom part of the adapter so it would fit properly my Yakima Forklift Rack. Now it works fantastic. The top hole is large enough for a Yakima skewer to go through so you don't have to put it through the lame bottom part of the adapter (which flops around unless it is tightened down really tight). See the attached photo. It works great now and flops around a lot less and is more secure. I had to make four cuts to modify it. Two to cut off the arms and then two at the front of the bracket to angle it so it would clamp to the rack with the Yakima skewer.
