Disc Brake Alarm Lock
You do not already have a primary lock.
This disc brake lock fits any disc over 6mm and triggers a 110dB alarm on the slightest vibration once armed. A press-to-lock mechanism makes it fast to use, the anti-drill lock core and IPX6 waterproof rating hold up outdoors, and a reminder cable stops you from riding off with it still attached.
