absoluteBLACK is dedicated to producing the world's finest oval chainrings and were the first to crack the code to discover the correct shape and 'clocking' to make an oval chainring work. They learned how to maximize the part of the stroke where power is produced and minimize resistance where it isn't which has the effect of smoothing out the delivery of power throughout the pedal stroke and improving efficiency. Many other brands have followed suit since then, but what sets absoluteBLACK apart is that they don't rely on the same formula across all sizes. The shape and timing of the oval is unique for every chainring size to ensure the pedalling solution is perfect for each one.
Every absoluteBLACK chainring is designed and manufactured in Europe with premium materials and outstanding attention to detail. Not every oval chainring out there is equal to an absoluteBLACK.
