Bifrost is a special color pattern of the all-polyester Kernmaster. The Bifrost is the Rainbow Bridge to Asgard in Norse mythology... seems fitting!

Ascend with minimal stretch and bounce thanks to the polyester core. Excellence in design and construction sets this super-static rope apart from the competition in performance. The distinctive color pattern sets it apart in appearance.

This special edition of the popular Kernmaster from Yale has a polyester core, making it a super-static SRS line. If you want minimal stretch in your SRS line, get this special Kernmaster while we have it! Smooth jacket will work flawlessly in your favorite ascenders or hybrid devices.

The core of this rope is red, making it easy to distinguish from nylon-core Kernmasters, and can aid in inspecting the outer jacket.

Bifrost a perfect SRS line

by Jason Cecil

I picked this up a few years ago after having been primarily using Samson mercury for SRS. The ease with which this line runs through mechanicals is unparalleled. There is a break in window when the line is new on a zig zag, but that’s it. Once the line is slapped around a little it’s great. Also makes a great replacement bridge… How the “F” are you gonna live forever in the halls of Valhalla if you don’t have a rainbow bridge?

Great rope

by Samantha

Fantastic SRT line. It is perfect for rope walking. Also, I have a hard time seeing colors, so the rainbow helps.
