The RigidFlex Stem design will stay rigid when placing the cam yet will flex when you climb past it preventing it from walking to far into the rock. Independent floating trigger wires the Camalot Z4 Offsets don\'t bend while under tension and retracted, but once placed allow the stem to move, ensuring a placement that stays put and doesn\'t walk when pulled directionally. The stem on the larger sizes also utilizes dual twisted cable which provides uniform flex in all directions, while single cable construction is implemented on smaller sizes to avoid buckling when pulling hard on the trigger and to reduce trigger profile. The offset sizes also ensure that you have the correct placement on hand for any, pin scars, non-uniform placements and irregular cracksSize 0.4/0.5RigidFlex stem stays rigid in-hand for easy placement but flexes once placed to reduce walkingDual twisted cable construction for uniform flex on larger sizes; single cable construction on smaller sizes to avoid buckling and reduce trigger profileNarrow head width for tight placementsSandblasted lobes for better holding powerLightweight yet durable Dynex sling with a unique colour scheme for easy identification from other CamalotsWeight: 64gStrength: 9knDimension: Closed 18.8 / Open 33.3mm
