Disc Brake Alarm Lock — 120dB with LED Light

120dB of Sound Deterrence

Sometimes the best lock is one that makes noise. Clip this disc brake alarm lock onto your wheel and any attempt to move the bike triggers a genuinely loud 120dB alarm — enough to make most thieves think twice and move on. When you don't need it locked, it doubles as an LED taillight on the included mount.
