The self-advancing knee ascender (SAKA) is a floating ascending device that is used along with a foot ascender (on the other foot) to allow you to climb using both legs in a stair-walking fashion (rope walker). Made by Climbing Innovations owner Richard Mumford, this is the fastest, lightest, and most efficient knee ascender on the market. It can be used with double rope technique (hitch pulley method) and many of the single rope technique applications. 


  • Patent pending, double bungee configuration (like DRT) makes for strong, fast and responsive ascender advancement.
  • Made from durable, quality materials.
  • Quality bungee with a single pure rubber core and a durable Dyneema cover. Replacement in a few minutes (if you ever do wear it out).
  • Works with both ClipN-style or regular climbing boots.
  • No extra moving parts to wear out, add weight or slow you down.
  • Footloop stays on your boot for fast and easy on and off, also minimized storage. Adjustable in seconds to reach any desired tending point.

You can see Richard's full description and demonstration here.

Rope-walking techniques greatly increase the climber’s speed. You’ll also get a much-improved climbing posture because the climber’s hands are above the climbing hitch or ascending device. In contrast to the bent-back position when climbing with the traditional “below the hitch” hand position, this straight-up body position also greatly decreases climber fatigue.

Advice: Always take small steps rather than high steps with rope-walking systems. Your knees and calf muscles can become over-strained and possibly injured taking high steps. Start out with 6” steps, and keep your hands as high as possible. Learn how to pace yourself by counting your steps on one leg (reps) before taking a rest period.
