Lighter and more convenient than ever before, the Black Diamond Camalot C4 brings the muscle without the heft. Coming in 10% lighter than its predecessor, this iteration saves grams without losing strength and maintains the same camming angle and placement ranges we have come to depend on. Giving the larger sizes stiffer stems, Black Diamond has uniformed flex across the line, so the 6 no longer feels wobblier than the 0. 3.
