Item Lock: Rings is a Gear Part that appears in Sonic Free Riders. It is an Extreme Gear component that influences all Item Boxes the rider touches to give Rings.
Item Lock: Rings is an installable performance-enhancing component for Extreme Gears. Its actual appearance is unknown, though it is presented as an icon on the head-up display in the top-left corner of the game screen. Its icon is a dark pink-colored circle with the image of a pink Item Box containing a pink swirl inscribed in it.
In gameplay, Item Lock: Rings is a customizable Gear Part that can only be attached to different Extreme Gears. It can be bought from the shop for 250 Rings after the player has completed the World Grand Prix.
When in use, Item Lock: Rings will influence every Item Box the player touches, except for Item Boxes that are set to a specific power-up, to only grant Rings, making it useful for the player if he/she constantly uses Rings throughout a race. Sometimes, the player may obtain two Rings items at once from an Item Box.
If Item Lock: Rings is installed into the front slot, it becomes active in gameplay once the race begins. If installed into the rear slot, however, the player can activate, and as well deactivate, Item Lock: Rings by switching stance by turning his/her body around due to the Kinect controls of the game.
