560G Titanium Bike Lock

Typically, bicycle locks either weigh a lot or are highly susceptible to physical attack. Altor’s 560G Titanium Bike Lock is neither of these things. It weighs just 560 grams (1.23 pounds) — hence the name — and is made of grade 5 titanium, the same used in aerospace and marine industries, to survive various sustained attacks including freezing, chiseling, cutting, and even large bolt cutters. A push button locking mechanism allows for attaching without fiddling with your keys and its folding design closes up tight so it won’t take up much space on your ride or in your bag. And it’s easily long enough to wrap around both your rear wire and frame, though two can be combined for an even lengthier, more versatile chain-style lock.
