Engineered specifically for the Etec Factory Turbo and due to the efficiency of the G4 and G5 platform, we can utilize our Blue series weights. These weights are crafted with a lower engagement threshold compared to our red profile, while maintaining an assertive shift profile to enhance your ride. Featuring advanced profile technology, the Blue Series Weights are among the lightest flyweights available, equipped with a uniquely aggressive ramp to build boost faster. This reduction in rotating mass within the clutch ensures a more responsive and agile experience.
Key features include:
Each weight provides 20g of adjustability, thanks to the included .85g and 1.7g magnets. The Etec 850 Stage 2 Kit includes everything you need for optimal performance—Advanced Profile Fly Weights, primary spring, helix, bushings, and magnets.
