Stirrup Style. For climbers over 5' tall. Patented design improves on the already ingenious HAAS® Ascent System by giving you an additional 18˝ of bungee in the system for a total of 30˝. Double tube system allows 30˝ of in-line bungee to be contained within the unit for over 30˝ of elongation. Versatile ascent system has zero set up and can be used by multiple users without adjustment. Snap is tied just above the ascender, extracting out up to 30˝ to eliminate any set up as well as any "dead spots" in the return action. Designed to maximize friction reduction with a bungee that terminates at the top of the Velox, travels down the channel to the bottom where it wraps around a shiv with stainless steel sealed bearings inside a machined aluminum block. Bungee returns up a second channel where it is tied to a snap. Bungee is replaceable in under five minutes without tools.
