Black Diamond Camalot Z4

The Black Diamond Camalot Z4 is a redefined version of the Classic C4 cam. The BD Z4 has all the answers to your cam frustrations.

With input from Black Diamonds top athletes the Z4 cam is a single-stem cam that stays rigid in-hand, thanks to the RigidFlex System. This new technology massively increases the ease of placements when sliding the cam in cracks but when the cam has been placed the stem flexes and decreases the chance of the cam walking/adjusting in the crack when being climbed above which makes sure your placement has the maximum chance of holding.

Independently floating trigger are used on the Camalot Z4 which make sure the cam doesn’t bend while under tension and retracted, but once placed allows the stem to move, ensuring a placement that stays put and doesn’t walk when pulled directionally.

The stem on the larger sizes also utilises dual twisted cable construction 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.

Featuring a similar head-width as the old BD Camalot C3 design, but with 4 lobes that are sandblasted for better holding power, the Z4’s are not only an upgrade, but are also available is smaller sizes. Starting from #0, Black Diamond's smallest cam ever made, and ranging to .75, allowing you to dial in the rack and have an tool for every job.

    The best microcam

    These are the business. Smallest headwidth, smallest size (green z4 goes smaller than the purple C3 or green dragonfly), great handling, bomber feel (I think due to the soft alloy). I was originally very excited about the DMM dragonfly microcams but overall was disappointed with them. The z4s are actually what I was waiting for. A set of microcams that are a step forward in every way. Well done BD these are truly innovative, feel great to place and that little green one goes places I never thought a cam could go!
