Fly up long approaches and sketchy redpoints with the super lightweight Sterling Fusion Nano 9.2mm Dry Climbing Rope.

You'll be amazed at the strength and durability of the Sterling Fusion Nano 9.2mm DryCore Climbing Rope. At such a small diameter, reduced rope drag lets the Sterling Nano float over rocks and through biners like a buttered baby on a water slide. But skinny don't mean flimsy—Sterling double-treats the Nano with their patented DryCore process, strengthening the core and the sheath. Use the Sterling Fusion Nano Rope for onsight climbs, redpoints, and alpine routes when weight and speed are of the essence.

Update your description!

ALL of Sterling's dynamic ropes have the Drycore treatment, even those not considered "dry" ropes. THIS rope, and other "dry" ropes, also have the Drycoat on the sheath. I confirmed this with Sterling. The Fusion Nano is only available as a dry rope (it was designed with ice climbing in mind), which means it has both treatments.

Excellent rope... if you use it right!

  • Familiarity: I've used it several times

The Sterling Fusion Nano DryCore Climbing Rope is one of the best ropes on the market for its size and intended use. I have the orange bi-color version of this rope and it is excellent for alpine, sport, and trad climbing where you need a combination of sturdiness and lightweight. The rope is nice and pliable in the hand, but can take a reasonable amount of abuse.

I was originally skeptical about using the Fusion Nano 9.2 as I have always employed thicker ropes (e.g. the Sterling Marathon) for my sport and trad climbing. But a rep from Sterling told me that he swears by it for situations when lightweight is crucial. He cautioned that this is not a good top-rope, gym rope, or a rope you are going to want to work a project with. If you are a beginner or want to use a rope regularly for more than 2 years, look elsewhere.

Instead, the Fusion Nano is EXCELLENT for when you have a route dialed in and are finally trying to snag an elusive redpoint. It is EXCELLENT if you are working an overhanging route where rope drag is minimal and your arms would be destroyed by excessive rope weight. The Fusion Nano comes (of course) with Sterling's DryCore treatment, which means that this rope will not be damaged easily by rain and snow and will have solid longevity as an alpine rope. If you are looking for a devoted AT/Ski Mountaineering rope, I would recommend checking out the Sterling Fusion Nano AT which comes in 30m lengths.

I have a feeling that a majority of the negative reviews here are because people are trying to use this rope in situations where a fatter/heavier rope would be much better suited. This is a must have rope for your climbing quiver... but I would not recommend it to be the only rope in your quiver.

Love this rope

  • Familiarity: I've put it through the wringer

I use the 80m on long trad routes. its long but light and usually save time because i can link together pitches and raps. So far it has been really tough. Its also i really soft catch witch is always great

Love this rope

Worst Sheath Ever!

  • Familiarity: I've put it through the wringer

I made it through only four routes before I had to retire this rope. It core shot on a rapell in Red Rocks when it gently grazed an edge. This rope would be fine for the gym or for some zero-rope-drag sport routes, but it has terrible durability.

Lacks Durability

  • Familiarity: I've used it several times

My friend bought this rope maybe a month ago and i have climbed with him on it a couple times. He already core shot the rope about 6 feet from the end of it and had to cut it. Also the sleeve looks like he has been using it heavly for months. It is a soft catch and everything but the durability of the rope is definetly questionable.

Amazing Rope

  • Familiarity: I've put it through the wringer

Intended use: Trad climbing, ice climbing, alpine adventures.
NOT intended use (my opinion): Sport climbing, projects, top-roping

-Fantastic hand
-Light weight
-Super resistant to water absorption
-Small sheath, not super durable

A climber that spends 50+ days a year climbing should probably buy a new rope each year. It's the cost of doing business.

This rope is a solid choice. It feels good and feeds well. It's got a good stretch and makes for comfy lead falls. Sterling has a great reputation and i have gotten great use out of their ropes before. My only concern is that the sheath seems to be wearing more quickly than other ropes i've had. The intregrity has not been compromised, and i fully expect to get at least 1 season out of it. But i am watching it closely.

As far as other comments about top roping, don't be dumb. get a 10mm or bigger if that's how you plan to use it.

Responded on

wore out much more quickly than i anticipated. maybe just cause it's a 9.2. my petzl 9.4 last A LOT longer though...

Stoked on Sterling Nano

If you're looking for the ultimate sport climbing rope, this one is IT! Has all the advantages of a fatter cord with much less weight and rope drag. I have had this rope for two years, with at least 150 climbing days on it and it still the sheath is intact with minimal wear. The greatest advantage of such a thin rope is not so much the weight but rather the virtual elimination of signficant rope drag. The difference is amazing. So imagine you are red pointing a 100 ft. steep sport pitch where the rope winds it way thru 13 or 15 quick draws and you go to pull up the rope and it's EASY. Seems like you just eliminated at least 10 pounds of effective weight! This rope also handles beautifully and compacts into a small package.

Only Cons: You probably should use a Grigri 2 rather than the older one although the older one will work on it. It's definitely harder to boink on but a prusik will solve that problem. It should be reserved for on sighting and redpointing as opposed to the "workout cord". Since it's intended purpose is for the former, that way it will last even longer.

Two Climbing Seasons Later

After initial impressions, this rope definitely held up to the abuse of a weekend warrior sport climber in Boulder, CO. Granted, I've gotten more into trad lately, but I think that if you're reasonably nice to this rope, you will see it go a long way. It went through trips to Red Rocks, trad in Eldo, and tons of trips up into Boulder Canyon.
-nice feel
-strong, durable, and held up to abuse
-great to fall on with a nice dynamic elongation
-light even at 70m
-if immediately straightened, this rope will not tangle often at all

-picks up dirt/grime easily so definitely use a tarp whenever possible
-for toproping, this will not be your rope- too much static elongation and frustrating to climb back up 5 feet that you just did unless your belayer is keeping you VERY tight

Overall, I would suggest this rope for those looking to break into harder sport grades. It's light and reliable. If you or your friends will be doing top-rope or tradding, this is probably too thin and will have too much static elongation for you. Great rope that I would suggest to most. As this rope's life was coming to an end, a buddy was playing around and went over a sharp ledge and almost completely cut the rope. It took a nice core shot toward the end, so I cut it shorter while my I decided on my next rope. It will be the slightly wider Sterling Evolution Velocity bicolor...

Fast and Light

This rope is the money for alpine climbing! You'll barely feel it on your back or in your pack on the approach. The small diameter and light weight makes handling it a breeze while leading or setting up belays. It lacks the durability of many fatter ropes but it's not meant for everyday use. Check out the Marathon pro for your workhorse! Another excellent product from Sterling!

The 9.2 Fusion Nano was the perfect rope for the Grand Traverse. Offering a perfect combo of lightweight and good durability for the raps over sharp edges.

Smooth and light

This rope feeds so very smoothly but you have to keep an eye on it in an older GriGri (no problems in the new GriGri2) at all. As all Sterling ropes, this thing has a great hand feel and I'm pretty psyched on the super bright pink color which pops more in photos and is sort of fun. This is not the thinnest cord I've used (9.1 Beal Joker) but is a great compromise for the weight. I'm not expecting to get more than a year out of this rope but I climb a lot so it's not a huge surprise as it was not designed or engineered for longevity.

Responded on

That's because the old grigri is only rated for ropes 10.0-11.0mm

not impressed

The sheath is wearing much faster than I would like. Probably have ~40 pitches of trad on this rope and the sheath is showing tons of deepish abrasions. No core shots yet. It also seems to love the dirt.

It is super light and handles smooth, but I wouldn't buy it again.

I bought this rope (60m bi-color) with the idea of taking it on long approaches into alpine environments, and it hasn't disappointed me yet. The thin diameter does take some getting used to, but once your up a pitch all thoughts of the rope being thin go out the window as you focus in on the main objective--getting to the top.

After 3 trips to the Lone Peak area in the Wasatch Front, and a week long trip on the long routes of Tuolumne Meadows, CA this rope has held up great with only 1 small sheath scuff. I would definitely recommend this to anyone looking for a lightweight lead rope they can trust in the mountains.

Great Rope

This rope has held up to a bunch of daytrips out to Boulder Canyon for sport climbing. It has a nice feel to it as a belayer, doesn't pick up much in the way of dirt/grime, and is super light when clipping biners at the top of a climb. I've also used a friend's Fusion Nano while ice climbing and it was awesome in those conditions as well. Only small gripe is that some friends think it's too thin and are scared to climb on it- their loss!

Similar to Beal Joker

Got this rope about a month ago and it seems to be holding up fine. It feels very similar to the Joker that it was bought to replace (which held up well for 3 years of weekend use). The Nano does seem to handle slightly stiffer, and the sheath seems more durable, but only time will tell. It also seems to be slightly thinner than the Joker (which is a 9.1), and every time out I get some kind of "is that a half rope?" comment. The intended use is alpine climbs, long slab pitches, and travelling, where space and weight is an issue. I don't intend to TR or sport climb on it, but I probably will at some point anyway.

One complaint, no center mark. I'll probably add one, but it I would have preferred they dip it in some well-tested rope dye at the factory rather than take a random Sharpie to it.

Pretty disappointed

Pat's review said this thing stands up to alot of abuse, but after 2 days of guiding on it, the rope had 2 core shots! The sheath literally seems to be deteriorating to the touch, quite scary really. Maybe I just got a bad cord, but your money is more wisely spent on another rope.

Responded on

maybe because this rope is for onsighting and redpointing hard sport routes, not guiding....

Responded on

agreed... not a guiding rope... actually its a bit scary to think someone would be guiding on a rope this thin

Responded on

i disagree. this thing held up a world of abuse, and only after a friend stupidly jumped over a ledge with a sharp edge did it get a core shot. if you are guiding, you probably wouldn't want this because of it's very high dynamic elasticity. you'll have many clients complaining about having to climb five feet plus over again.

Responded on

It's way too risky to guide on a skinny rope for a few reasons, not the least of which is trusting an inexperienced client to belay you with it. Thick rope = lots of friction = margin of safety. Also, this rope is not meant to be a "tool" in the sense that you're constantly on the rope (like clients will often be), repeatedly lowering, or taking multiple falls. Rather, this is meant to be a "just in case" rope, in scenarios where it will be weighted very little (tied in at an anchor, for example).
