For rock anywhere in the world.

You can rely on Trango's 9.0mm Catalyst Climbing Rope when you plan on climbing sport one day and alpine the next. Trango had this super skinny rope certified as a single rope, half rope, or twin rope for the utmost versatility in the vertical world. The rope's Unicore construction bonds the sheath to the core to enhance performance, increase durability, and eliminate sheathe slippage. Trango treated both core and sheath with Duo Dry for reliable resistance against moisture, dirt, and abrasion. A rope this skinny should only be used by highly experienced belayers and climbers.

Soft and Strong

  • Familiarity: I've put it through the wringer

This rope handles really well and has some really soft catches. Very light weight, but I'll agree with the other reviews that 9.0 starts to look a lot more like 9.4 after a season of use. I've taken this to Red River Gorge, the Wind Rivers, Smith Rock, and all over Utah and the rope is still smooth and intact. This is a great, soft rope for all your climbing needs.

One of my favorites

  • Familiarity: I've put it through the wringer

The Trango Catalyst climbing rope is one of the best handling ropes I have owned. It's lighter than a 9.2, but has the diameter more like a 9.4. On 40 meter pitches it had surprisingly little rope drag. All in all I give it 5 Stars.

Probably the best rope on the market

  • Familiarity: I've put it through the wringer

nobody has really heard of trango ropes but I can attest that they are amazing, especially the catalyst. 9.0 is not very accurate, more like a 9.4 when it's broken in. This is the most durable fluid skinny rope out there, due to the gluing of the core to the sheath
