The New RipCord ACE represents a quantum leap in fall-away rest design thanks to hundreds of hours of testing using high-speed camera footage. This footage resulted in fall-away optimization, something available only on the ACE. ACE is also the first micro-adjustable fall-away rest to offer micro-adjustability and a "narrow" hunting launcher. Micro-adjustability allows you to fine-tune rest position like never before. You won't believe how well you will shoot! The narrow hunting launcher is an innovation that dramatically increases vane clearance. And, ACE stays up when you let down to offer 100% arrow containment.
