KRYPTONITE Black U-Lock Includes two keys. I'm selling this because I bought it when I purchased a bicycle, but I ended up selling the bike soon after. This U-lock is from "KRYPTONITE," a lock manufacturer from Massachusetts, USA, known for supplying high-quality locks. This mini model is compact in size and lightweight while still boasting high security. It features two STAINLESS STEEL KEYS with an ergonomic design to reduce torque and prevent key breakage or bending. This is a reliable brand loved by messengers around the world. *Please note that the bracket mount for attaching to the frame or seat post is not included. - Brand: KRYPTONITE - Model: KEEPER - Color: Black - Accessories: 2 keys - Shape: U-lock - Retail Price: ¥9,350
