This didn't work for me. If you tighten the side strap the top strap is still so long that it can't work with a normal wheel. I brought 4 of these and I should have returned them right away I did find the chain ratchets very useful for use with a regular 2" strap so they were not a total loss. I think I'll take the top strap off and take it to a canvas shop and have them shorten them. It this price I think you should have a choice of 3 sizes, Sm, Med. and large. Sell a spare top strap for $6.99 in different sizes. Change what you haul? Change the top strap.
