The Kink Astro Spline Drive sprocket is a true mix of form and function.
Using heat-treated 4130 chromoly steel enables this sprocket to use thin spoke like patterns which create the unique look.
The design itself inspired by the structure of an atom, has increased strength over similar spoke style sprockets due to the intersecting “orbits” or spokes.
Please Note: 25t is only available in Black.
