Option #1 includes a primary spring, secondary spring, helix, and magnets. The weights are designed with a lower engagement and 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 result in less rotating mass in the clutch allowing for a more responsive and nimble ride. Each weight has 20 gram adjustability using the .85 gram and 1.7 gram magnets included.
