The patented double deadbolt locking mechanism has extensive holding power, while the reinforced internal housing has incredible resistance against twisting or leverage style attacks.

"Great lock excellent guarantee"
This is a quality lock at a great price. Kryptonite give you a £1000 anti-theft guarantee if you register the lock within 15 days of purchase which is really helpful and provides even more security. Comes with 3 keys I keep one on me have one at home and the other in the office. Weight is pretty good too whether you carry it in your bag or on your frame via the included attachment.

"A great lock"
This is a great lock. Its kept my bike safe across London and is not too heavy considering its rating. The plastic bracket could be a smoother operation but it does the job.
