Altor 560G Lock

Made from ultra high-strength Grade 5 titanium components, the 560G from Altor is the world’s lightest & strongest bike lock. With a total weight of 584 grams, the strength-to-weight ratio this thing delivers is absolutely insane; and the titanium super-alloy can withstand the most aggro attacks. The lock itself is a break-proof disc detainer type. Fully extended it is 26 inches in length & the design folds up to slim to stash in your pack.
