Asymmetrical Design:One side of the wheel is cut vertically (theLock-Inside), while the other side is rounded (theClassicside).
The "Lock-In" Edge:The straight inner wall is designed to help your trucks lock into grinds more securely on rails, ledges, and coping. It provides a stable "hook" that prevents the wheel from slipping off the surface.
The Rounded Edge:The outer side features a traditional shape, which makes the wheel more versatile for flip tricks and prevents it from catching on the ground during sharp turns.
