My vote: None ( 5 avg )


The Nano IX may be the most versatile rope in Sterling's line up. It's both the largest diameter half and skinniest single rope that we offer. Triple certified, the Nano IX is the top choice rope of many of our athletes for alpine climbs, extended expeditions and long routes where rope drag would be an issue.

NOTE: Due to the Nanos' small diameter, it is recommended that it only be used by experienced climbers and belayers and NOT for top-roping or working of routes. It is critical that proper belay devices be used and extreme caution should be taken.

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.

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.
