I bought a Pro-works quick load and its rubbish for my bikes (4RT and Beta ALP) - just doesn't lock them down securely as I think the pegs are too low compared to MX/enduro bikes.
I really like your set up @htrdoug - any chance of a bit more detail? Whats the rail on the floor and where did the solid rod come from? A quick Amazon search on J hooks doesnt bring up anything rod-like.
Cheers! P.
