Weaver 0898110 HAAS Velox Ascent System, Regular

The HAAS Velox makes the original HAAS even better; the floating knee ascender. It gives the climber an easier and faster way to ascend. It can be added to double rope systems, SRT systems, with the Rope Wrench, Hitchhiker, or without. Features a fully integrated knee ascender that captures all of the advancement made by your other foot. It does this by allowing the bungee to run past the ascender all the way to the foot through a liner where it then pulls the lower tether and ascender up the line from the bottom when it is un-weighted. The result is a smooth efficient ergonomically correct ascent that uses major muscle groups evenly and drastically reduces fatigue and stress. If you ever thought it would be cool to use two foot ascenders here is your chance.
