Everyday U-Lock with Bright, Easy Visibility
The Abus Ultra 410 U-Lock (11" x 6") is a straightforward, high-value lock for daily commuting and campus use. Its 12 mm hardened steel shackle resists common hand tools, while the compact body keeps things light enough to carry on the frame in the included SH34 bracket.
The black and green finish makes the lock easy to spot on a crowded rack, and the simple keyed mechanism is smooth and reliable for day-in, day-out use. Pair it with a cable or second lock if you regularly leave your bike in higher-risk locations, or run it on its own for quick stops and typical city errands.
