Description

The Nano 9.2mm, with its super skinny construction lives up to the Sterling Rope trademarks. So, no matter what happens to your skin, one constant you can count on is that the Nano will deliver high end performance and longterm durability on extreme onsights, redpoints, and alpine routes.
NOTE: Due to these ropes' small diameters, it is recommended they only be used for onsights, redpoints, and NOT for top-roping or working of routes. It is critical that proper belay devices be used and extreme caution should be taken

Rope Type

Type

There are 3 types of dynamic ropes that are used by climbers. They are known as Single, Half (Double), and Twin. The type of rope preferred varies by climbing style, location, and region.


Single

By far, the most common type of rope. Great for indoors and out. In the US, it is the most common sport and big wall and are also used for trad cragging. The handling is simple and the diameter options are quite varied.

Half (Double)

The best cure for a meandering route, only one of the ropes will clip into each piece of protection so a mindful climber can can reduce rope drag considerably. You can also rappel twice the distance, it’s easier to safely protect traverse pitches and there is a smaller chance that both ropes would become damaged (by rockfall, crampons, etc).

Twin

Both ropes must be clipped through each piece of protection. This is the lightest style of (two) ropes. They excel for rappels, going twice the distance vs a single rope, but do not have the ability to mitigate rope drag even though there are two ropes.

It is unlikely both ropes will be damaged at once, and is why many alpine, ice and mixed climbers choose twin and/or half ropes.

UIAA Falls (Single / Half / Twin)

UIAA Falls

This refers to the number of UIAA falls a rope has been tested to be able to withstand without breaking. The UIAA fall is a complicated test that is designed to create a uniform standard for strength in ropes, and is not generally reflective of real-world climbing situations. The test involves dropping a weight tied to the rope in such a way that it will see the highest amount of force a real-world situation could generate. The UIAA requires that Single and Half ropes must pass this test without breaking at least 5 times, while twin ropes must withstand 12 falls. In practice, it can likely be concluded that ropes that have higher than this standard number of falls will be stronger and put up with more abuse.


It is important to note that any rope that is UIAA or EN certified is considered safe to climb on, regardless of the number of UIAA falls it is rated for.

Dynamic Elongation (Single / Half / Twin)

Dynamic Elongation

This refers to the amount of stretch measured during the dynamic testing (or drop test) used when certifying ropes. Higher stretch will absorb more force and result in a softer catch but increases chances of groundfall at the beginning of a climb. The EN and UIAA require a stretch of at least 10% and no more than 40% for dynamic ropes. Single and Half ropes are tested individually and Twin ropes are tested as a pair.

Static Elongation (Single / Half / Twin)

Static Elongation

This refers to the amount of stretch measured during the static test used when certifying ropes. Most climbers will notice the difference in static elongation when climbing in a top rope situation, where higher stretch will make for a springier belay and could result in a ground fall when climbing closer to the ground. The EN and UIAA require a stretch of no more than 10% for Single and Twin ropes and no more than 12% for Half ropes. Single and Half ropes are tested individually and Twin ropes are tested as a pair.

Impact Force (Single / Half / Twin)

Impact Force

Impact force is the amount of force in kN that is measured at the testing mass during the UIAA dynamic drop rope test. When the weight is dropped, the force measured must be at or below 12kN for Single and Twin ropes and 8kN for Half ropes. The real world application of this test is determining that the rope can dissipate and absorb the appropriate amount of force from the fall as it would be felt by the climber. The variables used in the test set a situation that is well beyond anything climbers encounter, and shouldn't be considered realistic to actual climbing situations.


In reality forces of this magnitude would result in severe injury as this test is designed to test the limits of the rope and not the comfort of the climber.

Dry Treatment

Dry Treatment

When a rope is dry treated, it has had a coating applied to its core fibers, its sheath fibers, or both. The purpose of this coating is to reduce the amount of water the rope can absorb when in wet or icy conditions. Wet ropes are heavier, handle and belay differently, and have been tested to be weaker than dry ropes. Many climbers prefer dry treated ropes for very dusty or dirty environments, as they are more resistant to uptake of dirt and can stay cleaner longer.

RFID / NFC Option

RFID and NCF

This technology can be helpful if you are a gym or professional business where you'd like to track the usage and age of your ropes.

RFID is how items are uniquely identified using radio waves (Radio Frequency Identification). It's for 1-way communication from 10cm to 100m away depending on the frequency. Example: Airport Baggage.

NFC is a subset of RFID that is restrained to close proximity communication typically less than 10cm (Near Field Communication). NFC chips can operate a 2-way signal to exchange information. Example: Apple Pay.

Zion Adventures Logo

The sexiest of all ropes, Euros are skinny (less than 9.8mm) and brightly colored (read: pink). These ropes have an amazing strength-to-weight ratio, but tend to be less durable and are not suited for top rope climbing. They are designed for the weight-conscious climber ascending alpine and long, multi-pitch routes, and doing hard redpoint/onsight climbing. I believe the best rope in this category is the Sterling Nano 9.2mm. Sterling has earned a firm reputation for making extremely durable ropes, and even a rope this skinny can withstand some significant abuse. My climbing partner has one that has put in a full season in Zion and is still in great shape. It is rated for use as single rope, meaning it is strong enough to protect huge lead falls on its own, but can also be used in systems using two ropes (ie. half, twin, or double rope systems). This is more common in ice climbing, alpine, and some sketchy or meandering traditional climbs. For the sake of brevity, I will say I rarely use two ropes in this way, because it is messy, and not necessary for most climbing in Zion. Skinny ropes are expensive and made for specific types of climbing. Those looking for a rope they can take on any given climbing day probably want a rope with a larger diameter between 9.8 and 10.2mm, which brings us to…

Climbing Gear Review

Despite the thin diameter of the Nano, our testers enjoyed its stiffness-to-flexibility ratio. “Some ropes already feel coreshot when they’re brand new,” said a diehard skinny-rope user. But not so with the Nano. This rope is only available with a dry treatment and, like all ca. 9mm ropes, it has fairly high dynamic elongation (32.5 percent), meaning you could still drop a long way after the
belay comes tight. Do not toprope with this cord—it is best saved for redpoint or onsight attempts on steep terrain.
