Unicycle.com now stock Macaco 16m Slacklines
Slacklining is a balance sport that uses nylon webbing tensioned between two anchor points. The balance is similar to a unicycle and they are used by unicyclists as a balance tool. Some even ride their unicycles along the line. Slacklining is distinct from tightrope walking in that the line is not held rigidly taut (although it is still under some tension); it is dynamic, stretchy and bounces like a long narrow trampoline.
