I ordered the Sport tie down bundle by mistake; I thought the "Sport" tie downs were for the "Sport" rack that I have. The rear tie down is a good design with heavy duty hardware that goes over the rear tire and attaches to the rack with ratcheting straps. The front tie down has an expanding cuff arrangement that stretches to accommodate handlebar length. The cuffs slide over the handgrips, and straps inside the cuffs attach to the rack and tighten with ratchets. Rather than the single large piece with the cuff/strap arrangement, I prefer individual straps that I can attach to the handlebars one at a time, using the rearmost strap to hold the bike upright while I attach the other strap. I used the cuff strap once, and it held the bike securely, but I prefer (and use) individual straps.
