The gold standard in climbing because of the RigidFlex stem, the BD Camalot Z4 is the realization of a dream: to have a single-stem cam that stays rigid in-hand, but flexes once placed.

• RigidFlex stem stays rigid in-hand for easy placement, but flexes once placed to reduce walking
• Dual twisted cable construction for uniform flex on larger sizes; single cable construction on smaller sizes to avoid buckling and reduce trigger profile
• Narrow head width for tight placements
• Sandblasted lobes for better holding power
• Lightweight yet durable Dynex sling with a unique color scheme for easy identification from other Camalots
