Trango BigBro(TM) Expandable Tube Chocks are must have pieces for wide cracks. Their huge range and sleek design save on weight and racking space compared to large cams.
These puppies are big! For fist crack and offwidth aficionados, Big Bro's from Trango are your way to go! The expanding tube chock design 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 rope guide at the lip of a roof. Their expansion range is phenomenal-a #5 Big Bro has greater range than an entire set of traditional cams!Craig Luebben, the designer of the Big Bro, died in a tragic guiding accident in August of 2009. His royalty stream will go directly into a 529 college fund for his beloved daughter Giulia. Every Big Bro you buy will contribute money into Giulia's college fund. Just for fun, we asked Jeremy Collins to draw a caricature of Giulia that we're engraving on all of the Big Bro's.
The Big Bros by Trango Are the biggest, lightest wide crack protection on the planet. Named after George Orwell's book, 1984, in reference to Big Brother watching, Big Bros were designed by Craig Luebben as his Senior Design Project while an engineering student at CSU. Watch him stringing a line of these and you'll never even know he's not plugging cams. Big Bros Are happiest when placed in parallel sided cracks (think Utah sandstone) but, with practice, you can find secure, one-handed placements in a variety of crack geometries. The #5 Big Bro will protect up to an 18in. splitter and the smaller sizes Are great lightweight replacements for your fist-sized cams.
