Big Bro

Larger than most trad gear, Trango's Big Bro fits in offwidths and wide cracks quickly and simply. Get the weight off your shaky fist stack, stick a Big Bro in the crack, push the button to extend it to the right size, and twist the sleeve to lock it in place. Since Big Bros resist pull in any direction, they're nearly impossible to accidentally dislodge as you climb past. These unique protection pieces are lighter and easier to rack than similar sized cams, and they're the only hope for pro once you start climbing into chicken-wing sizes.

  • Trad piece is absolutely essential for wide offwidth climbs
  • Expands to secure placement with a simple button and screw lock
  • Unique design resists pulling out in any direction for extra security
  • Item #TRG0010

Use it right!

I've put it through the wringer
True to size

Once I learned how to use them I've stuck big bros in all types of cracks. They just take a bit more skill and effort to use right but once you figure it out you'll love big bros too.

Light, but not practical

Unfortunately there are just better spring loaded devices out there. When you're on a multi pitch this is the last thing you want to fiddle with. Very difficult to place and I don't thing it can be completely trusted. SLCDs just make more sense over this

I got the #4 Big Bro to expand my gear range. At its smallest it is like a tipped out #6 cam (BD or Wild Country). Sometimes it is just what you need!

#5 Big Bro

I thought the big bro would be much easier to place and get a bomber placement in an off-width than it is. I had trouble placing it in the off-width I thought it would work well for. But I have another one in mind and I think it should work for that one. Hopefully it will but so far it hasn't done me much good, just really big and expensive! Still love how badass it looks though, lol.

Hi cot4816335, do you have an update review?

Takes some time

After a while of fidgiting with these in safe conditions these can be your best choice for range and value if the conditions permit. A good way to set them is to wiggle them around then tightenthem then wiggle them some more then tighten again repeat untill secure. Works best if you can find a bump to help place. Definitely hard to use on lead if never had practice with.

You got big cracks You need a Big Bro!

If you're like me and enjoy body scrumming up a d&w (deep and wide) offwidth then Big Bros are worth the investment. My partner and I recently found a virgin offie smack dab in the middle of a sport climbing crag after some scouting we made the first ascent (we think cause no self-respecting sportie would submit their body to such torture) using BBs. For their range and value, four thumbs up way up from two sick offwits!

Big bros are half the size and weight of the #5 and 6 cams. My strategy is to place the cam first to gain peace of mind then use two hands to set the big bro securely. If I feel good about the bro placement, I remove the cam and repeat the process at the next wide spot. I can carry more bros than big cams.

ive heard you can use these as a rope guide on big roofs. is this possible? has anyone tried?
