Big Bros are must have pieces for wide cracks. They have a huge range and save on both weight and racking space compared to cams in a similar size. They also resist pull in any direction, adding to their security and your confidence as you climb past them. These expandable tube chocks protect on wider spots where heavier cams would add too much bulk and weight to a rack.
