The Shackle 12 Medium by Oxford delivers solid, everyday protection for your bike. It’s built from hardened 12 mm steel that resists cutting, sawing, and leverage attacks, giving you real peace of mind when locking up in busy areas.

This lock features a double-locking mechanism that secures both sides of the shackle for extra strength. The crossbar is reinforced and precision-engineered to resist twisting and prying. You’ll also find a protective vinyl coating that prevents frame scratches while keeping the lock looking clean.

For convenience, Oxford includes three high-security keys and a quick-release carry bracket, so you can mount it easily to your bike frame. The medium size offers a perfect balance between security and practicality – large enough to secure your frame and wheel, yet compact enough to carry on every ride.

Durable, strong, and easy to use – the Shackle 12 Medium is ideal for commuters, students, and riders who need dependable protection every day.
