Mountain Gear says:
Even though they're extremely lightweight and compactible, Black Diamond's Trail Shock Compact poles have a tough shock-absorbing system that compares with non-compact poles. Collapsible to a length of 24 inches for easy storage, these poles save weight with carbon fiber construction and a shorter grip length than the standard Trail Shock Pole. Get just the right height with an expansion range of 25 - 49 inches and Double FlickLocks to secure your pole length.
Historic Range: $54.98-$119.95
