Description |

Combining heavy-duty security and practical flexibility, the Kryptonite KryptoLok Standard U‑Lock with 4′ KryptoFlex Cable (Model 001966) is ideal for daily urban cycling. The 12.7 mm hardened performance steel U-shackle, paired with a patent-pending double deadbolt design, thwarts twist and leverage attacks. A high‑security disc-style cylinder resists picking and drilling, while a sliding dust cover protects the lock mechanism from dirt and moisture.

Included is a 4′ (≈120 cm) double-looped KryptoFlex cable, perfect for securing your front wheel or accessories, plus a FlexFrame‑U bracket for multiple mounting positions. The vinyl coating keeps your bike’s finish safe. Two ergonomic stainless steel keys are included, and the product is registered in Kryptonite’s Key Safe Program for replacement key support.
