For everyday cyclists, say goodbye to lost keys or forgotten combinations: the ABUS YARDO 7807F/85 chain lock opens in a fraction of a second thanks to its capacitive fingerprint sensor. The 7 mm thick, 85 cm long round steel chain provides solid theft protection, reinforced by a double ball-bearing locking mechanism. The die-cast zinc lock body stores up to 20 different fingerprints — convenient for sharing the bike with family or friends. IP66 and IP68 certified, it is dustproof and weather-resistant, while its silicone sleeve protects the frame from scratches. A CR2 battery is included.
