How to use 9.1mm Joker correctly, precautions, lifetime, care and maintenance with instructional pictures.
9.1mm Joker Unicore 50m 2xDry
Description
After having been the first thin rope on the market to meet the requirements for all three standards for dynamic ropes, JOKER will from now on benefit from the latest UNICORE technology. The JOKER, at one and the same time a single, double, and twin rope, is now UNICORE and will delight the most experienced climbers and alpinists seeking lightness, easy running and security, and at the same time the traditionalists looking for a multi-purpose rope for ridge climbs, or other classic, mixed or snow routes.
STRONG POINTS:
• Multipurpose.
• Ultra light and free running.
• The rope doesn't bunch up, and remains supple for the long term.
• Possesses all the advantages of the UNICORE technology.

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. Learn More
Every rope type and when to use them | Single/Half/Twin |
UIAA Falls (Single / Half / Twin)UIAA FallsThis 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. | 5 falls / 24 falls / 25 falls |
Dynamic Elongation (Single / Half / Twin)Dynamic ElongationThis 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. | 34.0 % / 32.0 % / 29.0 % |
Static Elongation (Single / Half / Twin)Static ElongationThis 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. | 8.0 % / 8.0 % / 7.0 % |
Impact Force (Single / Half / Twin)Impact ForceImpact 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. | 8.20 kN / 5.80 kN / 9.30 kN |
Dry TreatmentDry TreatmentWhen 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. Learn More

RFID / NFC OptionRFID and NCFThis 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. | None |

Ropes that are too stiff are always annoying and cumbersome to work with, and ones with a super soft hand never seem to last as long. The GriGri 2 was perfect with the Joker, feeding rope easily when the leader needed it, but also locked up the GriGri to catch falls securely. I used the Joker on several longer routes as both a single rope, and occasionally as a double rope, with the Guide ATC in auto-locking guide mode. Again, the 9.1mm diameter was great in the belay device, easy to reel in slack even when the second was climbing quickly in alpine terrain, but locking to catch a fall without issue.

No voice, but the demo speaks for itself as Beal cuts a traditional rope and a rope with Unicore technology. The difference is certainly dramatic.
