Light Blue/Yellow: This is our standard spring in our clutch kits, this has an engagement of 1800-2000 RPM in most cases
Teal: This spring will normally engage around 2000-2200 RPM and will pick up around 200 RPM peak. This is a good spring for the dunes as well that is a little better for slower riding than our solid light blue. This normally picks up the RPM lost by the high load of the sand and paddle tires making it an easier choice to swap the spring rather than change weights when going from tires to paddles. This all depends on your tire to paddle size, weight, and terrain.... you may still need to adjust weights.
Solid Light Blue: This is our race spring with a higher engagement between 2500-2700 RPM in most cases. Peak RPM will go up about 200-300 RPM peak over the blue/yellow spring so make sure you can install another 2 magnets in your AA clutch arms when installing this spring. Many will install this spring for dune riding instead of changing weights as it may pick up enough RPM needed. This all depends on your tire to paddle size, weight, and terrain.... you may still need to adjust weights.
