This tough cookie uses a 12mm hardened steel shackle to keep bike thieves at bay. The double-locking cylinder is a master of defense against picking, while the keyless combination entry means total convenience. It even passed the brutal ice spray test, so you know it can handle the pressure. Your high-end bicycle stays exactly where you left it with this robust, modern guardian.
