    Lightweight evolved.

    Sterling's superlight Evolution Aero Bi-Pattern Climbing Rope is the perfect companion while sending sport routes. The Evolution Aero achieves an ultralight weight thanks to Sterling's innovative core construction that also allows for a smoother belay. Sterling paired  that core with a durable sheath, so you'll be enjoying this lightweight rope for a surprising amount of time. A bi-pattern design makes it easy to rappel during sunset.

    Unanswered Question

    So I inspected this rope in person and even though it's technically a 9.2 it actually FEELS a lot thicker than the Sterling Ion R 9.4 and maybe even thicker than the Velocity 9.8. (The Helix also has this weird "thick" feeling). Any idea why? Is that caused by the higher sheath percentage?

    What belay device can I use with this rope?

    Hey Folks,

    Here is a list of belay devices and the diameter ropes that work with them:

    Petzl Reverso 4

    Item # PTZ0317

    Dia: 8.9-11mm

    Comments: The Reverso 4 goes down to an 8.9mm rope but I would not use a worn or seasoned Reverso 4 with this 9.2mm Sterling Evolution Aero Dry Bi-Pattern rope.

    Black Diamond ATC Guide

    Item # BLD1265

    Dia: 9-11mm (Single ropes) 7-11mm (Half & Twin ropes)

    Comments: I'd say this might not be the ideal belay device to pair with this rope since it is on one end of the range. This would be a good device if you plan on using the ropes in a half or twin rope system.

    Edelrid Mega Jul Belay Device

    Item # ELR000K

    Dia: 7.8-10.5mm

    Comments: This is more the ideal device to pair with this rope as 9.2mm is more in the middle of the range for rope diameters. And the auto-locking feature is a big plus that the other devices don't have.

    Mammut Wall Alpine Belay Device

    Item # MAM004D

    Dia: 7.5-10.5mm

    Comments: This would be a better alternative to the Reverso4 or the BD ATC Guide if you are not a fan of the Edelrid Mega Jul.

    Mammut Smart Alpine Belay Device

    Item # MAM0490

    Dia: 7.5-9.5mm

    Comments: Some folks love this device while others find it to a bit of a paradigm shift in belay technique but similar to the Mega Jul. It takes a bit of getting used to.

    Hello! I have four questions about this rope: (1) Is this rope compatible with any belay device? (2) Have you heard any feedback about how easy this rope handles when belaying (i.e. issues with rope control and friction when belaying, etc.), and rappelling (i.e. degree of rope control and friction when rappelling)? (3) Any feedback about how this rope compares to the Sterling Helix bicolour 9.5mm? (4) Any feedback about the durability of this rope? Many thanks for taking the time to respond to my many queries! Any feedback would be greatly appreciated!


    So here is the best information I have on this rope and I'll continue to dig into it for you.

    1- I'd recommend either the Edelrid Mega Jul belay device or the Mammut Alpine Belay Device since those have a range on the lower end of rope diamters.

    2- I have not yet. Soon I'll get my hands on a few more Sterling ropes (I have a BiAthlon pro myself) and plan putting them to the test. But the big thing Sterling has been saying about this rope is it's smooth handling.

    3- The big difference in terms of the ropes will be the extra 0.3mm in the Sterling Helix Bicolor 9.5mm rope. But the Helix 9.5mm will also have slightly less dynamic elongation and will be 3grams/meter heavier. But realistically, if you're not pinching weight for long approaches to get to long alpine climbs I'd stick with the Helix Bicolor 9.5mm

    4- At this time, having not climbed on the rope I can't comment accurately on the durability.
