What makes a good BMX sprocket?
A good BMX sprocket is CNC-machined from 7075-T6 aluminium - the alloy is noticeably stronger than the usual 6061. From about 6 mm thickness it offers enough stiffness even under high load. Spline drive or a classic sprocket mount is not a quality question - it has to match the crank. More on this in the category FAQ

kunstform Picks from the BMX Sprockets category
Our history with BMX parts did not start when we opened kunstform in 2003: some of the team have been riding longer than the shop has existed, and most of us are still on a bike today. So we know pretty well which parts we can trust. A kunstform Pick therefore only goes to what we would bolt onto our own bikes: parts where the quality and the value are right, and that you will enjoy for a long time.
