Introducing XEROS Technology... Jun 28th 2021
Sterling Rope Company created XEROS, which is a new way to manufacture a UIAA Certified dry rope. The XEROS technology is not a coating applied to the rope, or a separate liquid bath treatment. It’s a new step in the manufacturing process of individual nylon fibers, before they’re even twisted into yarn, that makes each fiber water resistant. When making dry rope using these fibers, the result is a product that blows traditional dry rope out of the water, it is more effective, wear resistant and better for the environment.
So, why are XEROS ropes so amazing?
Wet rope is weaker rope. The numbers don’t lie: Rope loses 20% to 40% of its strength when wet. And that can happen if you’re caught in a downpour, climbing an icy pitch, or even just dealing with prolonged exposure to high humidity.
The solution? Dry rope.
But it’s not a perfect solution. Traditional dry ropes are made “dry” with an exterior coating that keeps water out. That coating can wear (leaving the rope vulnerable to water), the finish can feel tacky (so it picks up dirt), and the process to coat the rope is labor-intensive—increasing cost and waste.
Sterling wanted to do better and went back to the drawing board for what a dry rope could be. In the process, they uncovered a whole new way to make dry rope.
This is XEROS technology
Through an exclusive partnership, Sterling spent the past three years working closely with their bluesign®-certified nylon yarn supplier to develop an entirely new way to manufacture dry rope.
Sterling has applied the XEROS technology to most of their climbing ropes, which significantly reduces the number of SKUS and helps make the rope buying process easier on consumers and dealers.
XEROS is exclusively available from Sterling Rope.
"Overall, I am blown away by the performance of the XEROS dry treatment. There is simply not enough to be said about its quality. The DryXP NanoIX we've all used for a long time is already my preferred rope and I'm psyched to see it evolve to the next level with XEROS technology."—Benny Lieber, Sterling Athlete and field tester
And that’s not the only thing that makes XEROS technology a breakthrough. Along with being PFOA-free, like all Sterling ropes, the XEROS technology process:
- Reduces waste
- Reduces energy use
- Reduces labor
In other words, this new process is better for the environment. And best of all, climbing rope with XEROS technology costs significantly less than rope made with traditional dry treatments. That’s right—there’s no premium to pay for a rope that’s truly ready for anything.
Stay strong in the wet
XEROS technology creates a dry rope with next-level performance—and without a sticky, vulnerable-to-wear outer coating. Because of the process, both the core and sheath are protected with XEROS, which reduces performance issues related to sheath slippage. All for a minimal price increase over traditional non-dry rope.
