Kryptonite's Keeper 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.
Standard Kryptonite U-lock size of 4 inches by 8 inches.
Includes a frame mounting bracket and 2 stainless steel keys. Free installation on to your bike when purchased in-store.
