Kryptonite Keeper 12 STD W/4" Flex Cable

The Kryptonite Keeper 12 STD uses a 12mm hardened steel shackle with a double deadbolt that resists twisting. A disc-style cylinder adds another layer of security, while the included 4' flex cable helps loop in your front wheel. At 2.40 lbs and sized at 4” x 8”, it balances portability with everyday protection, and the transport bracket keeps it steady on your frame between stops.
