Never Miss A Day
We never want you to miss a day of riding. If you ride hard, there's always a chance something could wear out or break. But don't worry - we've got you covered. Bindings with the "Never Miss a Day" feature come with a backup parts kit, including extra ladders, screws, and washers, so you can keep riding while sorting out replacements.
