With the AXA Defender and AXA Linq chain, your bike is strongly protected. This combination of a safe frame lock and a super secure chain lock complies with the Dutch ART 2 star, Sold Secure Silver, and Varefakta hallmarks, making it a reliable bike locking combo approved by almost every bike insurance. While the Defender locks through your wheel, preventing it from moving, the Linq chain lock has 9,5mm links with a deadbolt padlock for extra strong connection.
