Expandable Rock Climbing Tube Chock

These climbing puppies are big! For fist crack and offwidth aficionados, Trango Bigbros rule. The expanding tube chock design of this Trango Bigbros crack protection climbing gear is stable, lightweight, easy to use and strong. Because of their stable nature, when they're placed correctly they're almost impossible to dislodge when you're grunting by them, and they make a nice smooth rock climbing rope guide at the lip of a roof. Their expansion range is phenomenal, a #4 BigBro has greater range than an entire set of traditional cams!
