Engineered for daily riders, commuters and urban cyclists, the system balances theft resistance with convenient transport and use. The silicone outer cover protects your frame while the included bracket keeps the lock out of the way when you ride.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the ROCKBROS U lock resist cutting and tampering?\u003c\/h3\u003e\n\u003cp\u003eThe U shackle is made from heat-treated steel approximately 22 mm in diameter and tested for toughness to slow or deter common thieves. The lock uses a precise cylinder and a unique key profile designed to make picking and technical opening more difficult. Together these features raise the effort and time required to attack the lock.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHeat-treated steel shackle (~22 mm) for increased cut resistance\u003c\/li\u003e\n  \u003cli\u003eHigh-precision lock core with unique key to deter picking\u003c\/li\u003e\n  \u003cli\u003eProtective silicone cover prevents scratches while masking vulnerable edges\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat does the included 4 ft cable add to security and flexibility?\u003c\/h3\u003e\n\u003cp\u003eThe 1.2 m double-looped steel cable extends the reach of the U-lock so you can secure your bike to larger or irregular anchors like poles, fences and signposts. The cable is flexible enough to wrap through wheels or around awkward fixtures yet strong enough to resist forcible removal when paired with the U-lock. Use it when a single rigid shackle cannot reach both the frame and anchor.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-loop ends for easy attachment to the U-lock\u003c\/li\u003e\n  \u003cli\u003eFlexible steel core enables wrapping through frames or wheels\u003c\/li\u003e\n  \u003cli\u003e1.2 m\/4 ft length covers common urban anchoring needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow easy is it to carry and mount on a bike?\u003c\/h3\u003e\n\u003cp\u003eThe kit includes a compact mounting bracket sized to hold the U-lock securely on most bike frames, making transport fast and hands-free.
