Single stem microcams with a large expansion range and narrow head width.
The smallest three sizes of the X4 feature BD's Stacked Axle Technology, which uses a unique machined axle to give more expansion range per size than any other small four-cam unit on the market. The larger three sizes have double axles as per C4 Camalots. According to BD, this means that the six sizes of the Camalot X4 cover the same range as eight sizes of comparable units. In addition, and as per Aliens and Totem Cams, embedded cam springs allow for an ultra-narrow head width that fits in those tight spots that many other cams won't.
The cables are protected by aluminium beads which withstand repeated abrasion without compromising flexibility. They also have a hot-forged trigger bar and symmetric swage to improve handling and eliminate buckling. They have lightweight coloured Dyneema slings for easy identification and differentiation from other Camalots.
