ABSOLUTE BLACK chainring Road Winter oval 2-fold LK110 4 holes asymmetrical | gray inside
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.
The winter chainrings are specially designed for training in bad weather conditions. Compared to the Absolute Black Premium chainrings, they are 30% heavier, but have significantly fewer millings and are therefore less sensitive to dirt deposits and easier to clean. With a thickness of 5 millimeters, they are extremely rigid.
