Black Diamond Camalot C4 Ultralight

Black Diamond C4 Ultralight Cam

The Black Diamond C4 Camalot Ultralight is probably the lightest camming device out there. With a Dyneema core stem, instead of the traditional steel cable, the Ultralights shave weight but maintain strength throughout the unit. The cam lobes are sculpted and shaved to reduce weight further. Another weight-saving feature is the 14mm Dyneema tape sling which replaces the wider nylon of the standard C4.

It was the BD Camalot Ultralights that helped take Tommy Caldwell and Alex Honnold up The Nose on El Capitan in 1:58.07 to gain The Nose Speed Record!
