Abilities and traits
As a Skate type Extreme Gear in Sonic Riders: Zero Gravity, the Rail Linker is less powerful than most Extreme Gears, but is instead more agile. It can grind in Grind Areas by default and can slide at high speed.
When using the Rail Linker, the player will automatically start grinding in an approaching Grind Area while on the ground, unlike in other cases where the player has to press the Grind button to enter it. It will also automatically link onto a new nearby Grind Area when the player is reaching the end of another Grind Area while grinding.
