This upgrade kite allows you to upgrade the 2006 Cabrinha Crossbow and Switchblade to the latest 2007 centre line adjustment strap, which enables you to get rid of the plastic tubes that get caught up with the leader lines, but also it allows you to adjust the release tension of the override stopper ball to your desired tension or to completely lock it off.

A vast improvement over the 2006 system, and will fit on either Crossbow or Switchblade of 2006.

It just requires un doing the original system and replacing, a simple job.
