With the Steel-O-Flex Phantom 8960, locking and unlocking your bike is almost as much fun as riding it. You can lock your bike and park it with peace of mind. 17 mm thick steel shells encase the steel cable like scales. Like the other components of the Steel-O-Flex Phantom 8960, the shells are made of specially hardened steel and are incredibly difficult to bend. The Steel-O-Flex Phantom 8960 also offers convenience: the Fidlock magnetic mount makes it much easier to fit and remove the cable lock to and from the bike.
