If you like to ride fast and loose - this is the tyre for you!
The semi slick design of the Rock Razor means it rolls exceptionally fast. Tip it into a corner though and once the beefy side knobs take over the give fantastic grip. On hardpack or a little bit of loose over hard, the grip braking and climbing is exceptional. They are definitely out of their element in mud though!
