The HAAS Velox Ascent System – Regular helps climbers move up the rope faster and with less effort. Professional arborists and rope access users rely on it to improve climbing efficiency and reduce fatigue during long ascents.
The system uses HAAS’ double-tube bungee design to create up to 30 inches (76 cm) of elastic travel. As a result, it supports a smooth and natural stepping motion. The bungee passes through a low-friction aluminium block with sealed stainless-steel bearings. This setup allows the system to glide easily with each step. Therefore, it reduces drag and improves energy transfer on both SRT and DdRT climbing systems.
You can clip in and climb straight away because the Velox features a no-setup design. It does not require complex adjustments. The Regular size suits most adult climbers, which makes it a dependable everyday choice. In addition, the stable foot loop supports repeated use in demanding conditions.
HAAS engineered the Velox for heavy professional use. You can replace the bungee in under five minutes without tools. This saves time and helps extend the system’s working life. Consequently, it provides a cost-effective option for daily climbing tasks.
The HAAS Velox works as a climbing aid and does not provide life support. Therefore, climbers should use it alongside approved climbing and safety equipment.
Whether you tackle long vertical ascents or want better comfort in the tree, the HAAS Velox Ascent System – Regular delivers smooth performance and dependable support on every climb.
