Tendon provides a flexible solution for lifting the knee ascender, which improves efficiency when rope climbing.
A long length of high-performance elastic goes around the user's entire waist, providing a greater extension range and more consistent tension when stretched. The entire system packs down neatly when not in use.
The smooth and flared opening of the tube and the Dyneema sleeve on the elastic reduces wear, improves efficiency, and increases lifespan.
Tendon Tube Clips are designed to fit the attachment points on Kinisi harnesses.
The XSRE Swivel Carabiner (included) provides a secure and compact way to attach the knee ascender. With the addition of a second XSRE Swivel Carabiner*, both ends of the elastic can be attached, which doubles the lifting force and helps keep the system in line.
