The title says it all. I bought secondhand Thule Criterium bike holders only to realize they do not fit my Wingbar Evo Crossbar bars (The bike holders were a great deal so I didn't feel too bad). After some research, I figured out that they can be adapted to fit with XADAPT8 t-screws (https://amzn.to/39Ch2lz) and made this video to show just how easy it was installing them on my roof rack.

As promised here's a .pdf of the XADAP8 installation instructions.
