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.

      Comments about Big Bro Cams:

      I got this #1 Big Bro for my trad rack to go beyond my Camalot C4#3. The overlap just isn't enough for my taste, so I added the C4#4. I also got the #2 and #3 Big Bro's and that's as wide as I go. My only beef is that the cord holes were too sharp around the edges and needed to be chamfered. Use 3 feet of 5.5 Dyneema cord with triple fisherman knots for each Bro.
