ABSOLUTE BLACK chainring Road Oval 2-fold LK 110 4 holes asymmetrical | black inside
Absolute Black's chainrings are CNC-machined 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.
Note: The images show the previous version for Dura Ace 9000 and Ultegra 6800 cranks .
