The Blue series weights are back and better than before! Built just for the Patriot, The Blue series weights are designed with a lower engagement and an aggressive shift profile in mind.

Lighter fly weights results in less rotating mass in the clutch allowing for a more responsive and nimble ride.Each weight has 20g adjustability using the .85g and 1.7g magnets included. Patriot 850 stage 2 includes primary spring, helix, bushings, and magnets.
