The Blue series weights are designed with a lower engagement than our red profile but still with an aggressive shift profile in mind. The advanced profile weights offer the industry’s lightest fly weights with a uniquely aggressive ramp. Lighter fly weights results in less rotating mass in the clutch allowing for a more responsive and nimble ride. Each weight has 20g adjust-ability using the .85g and 1.7g magnets included. Axys stage 1 kit contains: primary spring, bushings, and magnets.
