A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these products answer different questions.
The lock for a standard city rack. Its tight shackle is its main strength, and it comes with a frame bracket.
The lock for a valuable bike. It has the top grade and enough reach for most racks, at nearly the same price.
Sold Secure rates the KOHLBURG one grade higher. A tighter shackle still helps the Kryptonite in real use.
