Description
ABSOLUTE BLACK chain ring Road oval Premium 2-fold LK 110 4 holes asymmetric | Dura Ace 9100 | Ultegra R8000 | PVD rainbow outside
Absolute Black chainrings are CNC-milled from a single 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 appropriately 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. The weight is kept low thanks to the large cut-outs and they make the chainrings an eye-catcher. The oval shape smooths out the power peaks during the crank revolution. 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. Due to the special PVD Rainbow Titanium coating process, the chainrings are very durable and each color is incredibly individual.
Note: You can find the right screw covers for your Shimano Dura-Ace or Ultegra cranks in our shop.
