The Attack Ring (アタックリング, Atakku Ringu) is a component of 1st generation Beyblades that determine how Beyblade tops engage each other when they collide in battle. These parts come in a variety of elaborate shapes and sizes, often inspired by the mythological beasts and monsters.
The Attack Ring determines the blade's effect when it impacts against its opponent, as this is normally the first part to come into contact with the opposing blade. Also, the Attack Ring holds the Bit Chip in place on the top, preventing it from coming off mid-battle.
It is often the part that makes contact with opposing Beyblades first hence it's name. Attack Rings are decorated with various spikes and protrusions that accentuate its Type characteristics: Attack, Defense, Stamina etc.
