I got this strap because I have 2 different SeaSucker setups, and wanted an alternative for deep-dish and MTB wheels. This strap is SUPER long. I'm not sure how long the standard length is, but this will cover nearly every depth/width imaginable. I'm strapping down the equivalent of a Zipp 404 and have many inches to spare. The pack includes a strap pad to keep excess length from scratching my roof - a nice addition. Deducted one star because the details on the website articulating the differences between the two versions of these items is scant.
