Works well with my road and CX bikes, but does not actually fit a mid fat 29x3 (mine is a trek stache) as the description says. Another review also confirms this. The arm needs to be longer to grab the ratchet. I actually have two of these bolted to the front of my truck bed instead of using the tailgate to secure them. They work well for most bikes as I said, Thule just needs to either make the arms longer or correct the stated range of use.
