Fusion Series
The Fusion series is the preferred choice of advanced climbers and Sterling Team members. Weights are kept to the bare minimum and each rope is designed to have class-leading performance characteristics. Sterling’s Fusion ropes are designed to perform at the highest level–pure and simple.
Fusion Nano IX
Sterling’s original Nano was a perennial team favorite; the default sport climbing rope for performance climbers. Certified as a single, half, and twin rope the Nano IX 9.0mm is lean, mean and versatile: perfect for sport routes, ice, or mixed conditions. Available with new DryXP treatment, UIAA Certified Water Repellent.
Non bicolor options include a Middle Mark. (Except for Olive Drab)
NOTE: Due to the Nano’s 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.
Available Lengths: 30, 40, 50, 60, 70, 80 m // DryXP standard in all lengths

Fusion Ion R
Sterling’s latest version of the renowned Ion dynamic rope, they have retained the signature characteristics climbers always raved about: the comfortable handling sheath and the ideal 9.4mm diameter. But to enhance its performance profile, Sterling radically updated the construction. They like to call it a crossover artist within their Fusion series- it performs well across multiple climbing disciplines without playing favorites.
Non bicolor options include a Middle Mark. (Except for Olive Drab)
Available Lengths: 40, 50, 60, 70, 80 m // DryXP in 60, 70, 80 m

Evolution Series
Sterling launched the Evolution series over 20 years ago and have continually updated it—infusing each rope in the series with the latest technology—so they retain their well-earned position as the gold-standard dynamic ropes that adapt to whatever the climbing style or conditions call for.
Evolution Aero
With a 9.2mm diameter, the Aero is the lightest rope in the Evolution Series. The Aero balances a durable, tough sheath with a new lighter weight core construction. The result is a sending rope with softer handling that’s ideal for sport, mixed and ice climbing applications.
Non bicolor options include a Middle Mark.
Available Lengths: 50, 60, 70, 80 m // DryXP available in 60, 70, 80 m lengths

Evolution Helix
Small but mighty: With a new sheath and bantam weight core construction, the Helix is Sterling’s skinny workhorse. Blending the right features—the ease of the 9.5mm diameter rope, durable and light with low impact force—the Helix is ideal for high-end sport, trad and mixed climbing. Now available in DryXP, UIAA Certified Water Repellent.
Non bicolor options include a Middle Mark.
Available Lengths: 40, 50, 60, 70, 80 m // DryXP available in 60, 70, 80 m lengths

Evolution Velocity
Versatile and varied, the Velocity 9.8mm is the quintessential all-rounder. Suited for both rock and ice, the Velocity is the flagship of the Sterling lineup: lightweight, durable, long-lasting and easy to handle. A favorite among world-renowned athletes for working routes, the Velocity is a must-have for kitting out any crag pack. Now available in new DryXP, UIAA Certified Water Repellent

Marathon Series
The Marathon Series is designed to outlast other ropes in extreme conditions, where durability is paramount: Big walls, multi-pitch climbs, institutional usage, remote first ascents—all these types of climbs require something extra. The Marathon Series is made up of several rope models, each designed for a specific purpose but all come with the thicker and more durable Marathon sheath construction for greater longevity and durability.
Marathon Pro
The thinnest Marathon rope, the Pro 10.1mm is no less a workhorse than its larger brethren. Drawing its design from the demands of professional guides, the Pro’s burly, long-lasting exterior is specifically designed to stand up to wear and tear of rigorous climbing. Well built but not overbuilt, it will put you at ease when working your demanding project. The Pro exemplifies what a modern day climbing rope should be: a work rope and redpoint rope.
Non bipattern options include a Middle Mark. (Except for Olive Drab)
Available Lengths: 50, 60, 70, 80 m // DryCoat available in all lengths.

Marathon Sport
The Sport’s unique core and durable Marathon sheath is why Sonnie Trotter picked this 10.4mm rope for The Prophet, a bold, run-out, 600 metre El Cap behemoth. Able to handle the hard abuse of big wall climbing—with run-outs, big falls and demanding maneuvers, the Sport’s toughness gives you the confidence for the biggest, boldest sends.
Available Lengths: 50, 60, 70 m // DryCoat available in all lengths
