HAAS Velox Ascent System
The bungee is terminated at the top of the Velox and travels down through a channel to the bottom. Here it is wrapped around a shiv with stainless steel sealed bearings inside a machined aluminum block for maximum friction reduction. It then returns back up a second channel where it is tied to the snap. The result is 31 inches of inline bungee contained in the system at rest, allowing 30 inches to be extracted under load.
