The Subrosa Warhead XL Cable Lock features a 10mm thick stainless steel braided cable with plastic cover and steel locking mechanism for strength. The extra long 7ft cable of the Warhead XL is ideal for locking up multiple bikes or other personal items where you might need the extra cable length. Although this lock offers a greater level of security, it is not intended for overnight protection and is best suited for medium level security such as bike rack use or quick stops for food. Includes 2 keys.
