I installed these on my bike and attach the ratchet tie down strap to them. Work well. http://pitposse.com/potilo.html
I also use those with straps and use a ratchet strap on the kit pulling towards the back of the deck. we do this with 4 bikes on a sled deck.
It is a mess of straps but there is no way that the risk setup or many others really will work with 4 bikes on a deck and most of us run the yeti wheels. And there is no way i am taking the yeti wheels off as i ride my bike up the sled ramp with them. Cant do that with any other setup.
i just looked at these at the Sled show yesterday and think they would be the only setup i would consider spending money on but then i need to add even more track to my deck all over the place
