Abus 410K/170HB230 SH Ultra + Cobra

An 8/15 rating indicates a solid level of protection suitable for medium-risk areas or shorter stops. It is designed to deter opportunistic thieves, though for high-theft urban environments or overnight storage, you might consider pairing it with a higher-rated chain or lock.

The Cobra cable acts as a secondary security measure. You can loop it through your front wheel or saddle and then secure both ends within the U-lock shackle, allowing you to lock more of your bike components without needing a second lock.

The bracket is designed to fit most standard bicycle frames, but it works best on round tubing. If your bike has an unusually shaped or oversized frame, you may need to check the clearance or consider carrying the lock in a bag.

The 12mm thickness refers to the steel diameter, not the internal clearance. The shackle provides enough internal space to lock your frame and rear wheel to most standard bike racks, poles, or parking meters.

The double-bolt mechanism locks both sides of the shackle into the crossbar. This significantly increases resistance against twisting attacks, where a thief might try to use a lever to pry the lock open.
