All the speed you need to hit the gnarliest gaps and rails. The 10' Bungee Package from Banshee Bungee stretches up to 70 feet giving you more than enough speed to shredd across nearly any surface. If you need more tenacious speed you can double up the bungee or if you're sessioning a tight gap and don't need all 10 feet, simply tie it off short on your anchor point.
Bungees work modularly, so if it is more speed you crave double this sucker up, and if you need a longer pull simply hook another banshee bungee up to it. With speeds approaching 35MPH, it abandons the need for a car tow.
