Kryptonite's Keeper Standard U-Lock has been upgraded to a stronger, bottom keyed, deadbolt locking mechanism to make it more competitive with OnGuard's Bulldog series.
Constructed with a 12mm hardened steel shackle and coated in vinyl for frame protection, this new version also has a smaller, pick proof, disc style lock cylinder.
This lock is 12X stronger than the older key in the side design and offers purchasable $500 anti-theft insurance.
Standard Kryptonite U-lock size of 4 inches by 8 inches.
Add a double ended cable to secure your wheels to the U-Lock for greater security.
Includes a frame mounting bracket and 2 stainless steel keys.
Free installation on to your bike when purchased in-store.
