MCS chainrings are CNC machined in the USA with precision from a solid piece of 6061 aluminium, which gives you a drive sprocket that is not only strong and light but durable as well.
They come in a range of sizes and colours and suit all levels of BMX racing. This is the 4 bolt 104BCD variant: MCS also make the same ring in a 5 bolt pattern if that is what your cranks take.
