I reverse engineered this product by Yakima when I finished building my new mountain bike and realized the 15mm thru axle front fork was not compatible with the existing 9mm quick release based Yakima Viper car roof rack.  I promptly ordered the Yakima HighRoller off Promotive but in the meantime I used my prototype that I made based off caliper measurements of my viper rack and pictures I found on Yakima’s website.

Here's the Yakima 15mm Fork Adapter (MSRP $49)

Here is my prototype. This was designed in SolidWorks and created with an Objet. This prototype withstood highway forces with a 30Lb mountain bike for 50-60 miles during the week my HighRoller was on order.
