Extremely strong XX15 disc-lock alarm.
Mono-bloc 304 stainless-steel body and piercing 120dB alarm
with carbide-reinforced double-locking pin.
Another great thing, disc lock alarms. I’ve got two, one on each wheel. If the bike starts moving they go off and make a right ruckus, just what the thieves hate.
