BSD's original sprocket has been in production for over 20 years now & shows no signs of stopping anytime soon. Made from fully CNC machined, super-tough 7075-T6 aluminium the Superlite Sprocket is 8mm thick at the edges & tapers down to 6mm at the center to save weight. This makes that tri-spoke design way stronger than it looks. The center bore is 24mm, with 19mm & 22mm adapters included to fit all cranks. section Product Specs TYPE: Bolt On
