ABSOLUTE BLACK chainring Road Oval 2 times LK110 4 holes asymmetrical gray outside
Absolute Black's chainrings are CNC-milled from one piece of aluminum, creating the perfect combination of low weight and excellent durability for your bike. The oval shape smooths the force peaks during the crank rotation. As a result, you have a more even step, especially on the mountain, and the muscles tire less. The lower force peaks also reduce the stress on the knees.
