If you already have enough keys in your life, the Shackleton is the ticket. You can program in your own four digit code for easy opening each time.
The Shackleton boasts a hardened steel shackle and a double deadbolt lock mechanism that resists drilling, picking, bumping, pulling and prying.
Silicone cover over the steel U will protect your bike frame.
Includes a frame mounting bracket and includes free installation onto your bike when purchased in-store.
We think this is the least expensive bike lock you should buy.
Add a double ended cable to secure your wheels to the U-Lock for greater security.
