RockyMounts Shackleton Combo U-Lock Black, One Size

The Rocky Mounts Shackleton Combo U-Lock takes the security of a steel U-lock and combines it with the convenience of a keyless, combination entry. The combination panel is programmable so you can pick your four digits, making it quick and easy for you or someone you trust to access your bike. A silicone overmold protects your frame's paint job, and an included frame mount makes the Shackleton easy to ride with.
