I use them all the time on all my bikes, dirt and road. Yes road bikes also. Many people don't realize that there are at least 2 types, The kind most people use for dirt bikes that fitts under your fender and on you tire, then the ones for most road bikes that go on your down tubes between the dust cap and the triple tree so it will not touch the fender. The ones I use for the dirt bikes are made of a 4x4 notched on the top to fit in the fender and curved to the profile of the tire and a bungie to hold in in place while cinching it down. My road bike version is made from PVC pipe to wrap around the fork tube much like a fork seal insertion tool but with a internal clearance cut out so it will not press on the dust seal lip and velcro strap to hold the two halves together. I have never had one fall out, scratch a tube, blow a seal or create a pinch flat. On the road bikes I strap the back end down lightly also just because of the weight . I do not strap down the dirt bikes rear ends and they do not migrate more than a few mm eaven on logging roads. I think that little movement is just the bike squareing up to the handle bars. I've never dropped a bike in the bed or trailer nor have I had two bikes touch during transportation. I believe in them and ratchet straps.
