The Black Diamond Camalot Z4 is built for the crack sizes where head width and stem behavior decide whether a placement is bomber or sketchy. In pin scars, flared tips, and horizontal breaks, the narrow C3-derived head profile and independently floating trigger wires work together: the head enters constrictions a standard Camalot can't reach, and the stem holds its line under trigger tension so the placement goes exactly where it needs to go. The double-axle design from size . 3 up widens each unit's individual placement range so the right cam is already on the harness. What Our Gearhead® Experts Are Saying:"The RigidFlex stem is what separates this from other small cams. The stem stays stiff while I'm placing it so I can actually steer the head into a tight constriction, then flexes once it's loaded to reduce walking in horizontals."
