9.0mm Fusion Nano IX 30m 2xDry



no ratings


Our original Nano was a perennial team favorite- the default sport climbing rope of choice for performance climbers. Now it gets reimagined as a triple threat: The Nano IX (Nine) arrives in a leaner (9mm), meaner, more versatile incarnation. Perfect for sport routes, ice, or mixed conditions, the Nano IX confidently surpasses expectations. Certified as a single, half, and twin rope, you get exceptional performance in a skinnier version of its very popular predecessor.

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

We like a lot of things about the Sterling Fusion Nano IX. It's lightweight, handles well, and it fared pretty well during our tests. This is a great rope for certain situations, like a hard onsighting on a long route, but it's not the best everyday cragging rope. The new DryXP treatment also makes it suitable for Alpine and Ice climbs, though the rise of the Unicore lines has us preferring them in those situations due to the extra bit of safety that they provide. The Nano is still a great line though, and we'll be bringing this one out for those routes that go on forever.

Blister Gear Review no rating given just a review

The Sterling Fusion Nano IX was an excellent rope when it was first released two years ago, and it’s still near the top of the pack for skinny ropes. The new DryXP treatment in particular is excellent; I think when combined with the higher sheath-to-core proportion and inclusion of a middle mark, the new Nano IX is definitely an improvement over the previous version of the rope. That said, if you’re looking for a super durable rope, there are slightly burlier options out there, even at similar diameters. So, while I wouldn’t go out and replace a perfectly good rope based on these factors alone, if you’re in the market for a new skinny dry-treated rope, the Sterling Fusion Nano IX is an excellent choice.

Outdoor Gear Lab Gear Review rating 5/5

The exceptional low weight and smooth handling are ultimately the reasons why the Nano IX took home our Top Pick award for the best alpine/sending rope. Shoppers should be aware that its small diameter did compromise its durability in our tests. But if you can stomach the fragility, this rope provides the weight savings to get you up your most ambitious goals.

The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
