ABSOLUTE BLACK chainring Road oval 2-fold LK 110 4 holes asymmetrical | Dura Ace 9100 | Ultegra R8000 | black 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. Elaborately milled switching ramps ensure excellent switching performance. For maximum shifting efficiency, the chainrings should be combined with the correspondingly optimized small chainring (53-39, 52-38 / 36, 50-34). Thanks to the milling of a 5 millimeter thick aluminum plate, the Absolute Black chainrings are among the stiffest on the market. Due to the large cutouts, the weight is still kept low and they make the chainrings an eye-catcher. 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: You can find the right screw covers for your Shimano Dura-Ace or Ultegra cranks in our shop.
