Recently I bought a post mounted rack for my road bike.I want to carry my clothe and stuff to my PT job at my LBS. I pu tmy stuff in a a small nylon duffle and started with cheapie 1/4"diameter bungies from Home Depot, my former PT job. I seem to get too much sliding with this set-up. So my wife made me a couple web straps and still the sliding.
Has anyone devised a strap using old tubes but with some kind of buckle?
