The Astro sprocket is a true mix of form and function. Using heat-treated 4130 Chromoly steel enables this sprocket to use thin spoke-like patterns that create a unique look. The design itself inspired by the structure of an atom and has increased strength over similar spoke-style sprockets due to the intersecting "orbits" or spokes.
