2017 Sterling Fusion Nano IX Rope
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.
