Auvray B-Lock-14 SRA Class Disc Alarm Yellow/Black

Secure high-value road bikes with confidence using the Auvray B-Lock-14 SRA Class Disc Alarm.

Designed for cyclists who demand reliable protection during urban stops or extended outdoor storage, this lock combines physical strength with an integrated alarm system to deter theft effectively.

The B-Lock-14 integrates a 120dB alarm that activates on movement, providing both visual and audible deterrence. Its 14mm spindle resists cutting attempts, while a double-locking mechanism and tamper-resistant cylinder add layers of security. Built to withstand variable weather, the stainless steel construction and sealed electronics ensure consistent performance through rain or shine. With no on/off switch, the alarm system activates automatically—eliminating user error and simplifying deployment.
