This unique lock combines near U-Lock security with the ease-of-use and versatility of a cable lock. Remarkably compact, the K-9 is constructed of hardened steel plates and features OnGuard’s pick, pull, and drill-proof cylinder with sliding keyhole cover. Once unfolded, the K-9 has the length to secure frames and wheels to a rack or other solid object. Included mounting bracket features easy, push-button release, dedicated water-bottle hole mounting or all-tube strap-mounting to fit other parts of the bike. A water bottle cage can also be mounted directly to the bracket for added versatility.
