The Black Diamond Standard Flex Centre Bar is a standard sized spring-steel centre bar that allows you to adjust your crampons to fit your boots.

Compatible with all BD crampons the Standard Flex Centre Bar is perfect for regular foot sizes and is sold in pairs. The old version is identical in shape to the current version but it is constructed on two pieces of metal which are spot welded at one end.
