9.8mm Evolution Velocity 70m Bicolor



no ratings


Just like the solid Velocity this 9.8mm rope has it all and is our most popular of the Evolution series. Just the right amount of stiffness, so your rope doesn't flop during critical clips and its silky smooth sheath withstands abrasion and slides effortlessly to reduce rope drag.
What makes Sterlings BiColor ropes unique and a leader in industry is the dramatic color change in the middle. Finding the center is easy, quick and accurate, even in low light situations. These ropes have the same construction and award winning performance as their single color namesakes.

Chicks With Picks Gear Review no rating given just a review

In the fall of 2014, when Kitty Calhoun and I made our gear list for climbing Tangerine Trip, a big-wall aid route on El Cap in Yosemite, it was I who said “I got the lead rope”.  I had been climbing with my 9.8mm Evolution Velocity for a summer and it had proven itself with strength, durability, and handling.  Just what you need when you’re about to head up the biggest piece of rock there is in the lower 48!

Good “workhorse ropes” are ones those that can take a beating but are also reasonably light for long approaches and use on big wall climbs. There are many great ropes in this category, but my favorites are the Mammut Tusk 9.8mm, the Sterling Velocity 9.8mm, and the Maxim Glider 9.9mm. These ropes have displayed great durability, have a nice “hand” (supple, smooth), and have kept me alive in many uncertain circumstances. Ropes with a diameter less than 10mm feature good balance of weight and durability, nice movement through belay/rappel devices, and a tendency of NOT breaking the bank. These ropes are most appropriate for lead climbing, but are also good for top roping so long as they are not moving across a lot of sharp edges. For people that are primarily top-roping, a thicker rope is more appropriate because there is simply more sheath to protect the core from abrasion.

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.
