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.

Every rope type and when to use them
Single ­
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.

Outdoor Gear Lab Gear Review rating 5/5

The name Infinity does a good job of indicating the outstanding level of durability that you can expect from this slim cord. But it is also the solid performance it offers in low weight, catch, and handling that make it such a well balanced rope and our Editors' Choice winner. There are many other ropes out there that might surpass the Infinity for one particular application, but none of them can match the consistent benefits across a range of disciplines. If you can only have one rope, you can't do any better than the Mammut Infinity.

Climbing Zine Gear Review no rating given just a review

This is another high quality rope from Mammut. It fits perfectly into the category of light and functional, not something you use merely for your sport climbing project, but one you can also trust for a long day climb. All things considered probably one of the best all around ropes on the market right now.

Blister Gear Review no rating given just a review

I was extremely impressed by its handling and performance in all non-specialty scenarios and, from a durability standpoint, it still looked very good after a whole season of climbing. The Infinity sets the bar for the “one-rope quiver” pretty high, and it’ll be exciting to see if this new, thinner generation can top it.

Dream in Vertical Logo

Upon my return I purchased a 60m Mammut Infinity 9.5mm . This rope has been awesome and quite durable. While it is marketed as 9.5 it feels fairly thick and definitely fuzzed up a bit over the years, so it doesn’t feed super fast in a Gri-Gri. Regardless, I enjoy the clipping action and even though we had to cut the ends off, making it only about 155 feet, I still like using it. So far this is my favorite rope and at some point I will likely get a new one of the 70 meter variety. It is light enough for a hard redpoint but still durable to last on day of projecting.

Climbing Gear Review rating A

Summary: Mammut’s Infinity strikes a balance between light weight, durability, and handling. Virtually kink-free right out of the factory coil, this cord clipped well, held up to extended working sessions, and fed smoothly through allbelay devices. Those with tender hands should opt for belay gloves, as a few testers found the sheath to be a bit coarse.
Pros: Lightweight. Durable.
Cons: Coarse sheath.
