ABSOLUTE BLACK Chainring Premium Round Road 2-fold LK 110 4 hole asymmetric | Dura Ace R9100 | Ultegra R8000 | gray outside
The Absolute Black chainrings are CNC machined 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 appropriately optimized small chainring (53-39, 52-38 / 36, 50-34). Thanks to the milling of a 5 mm thick aluminum plate Absolute Black chainrings are among the stiffest on the market. Due to the large cut-outs, the weight is still kept low and they make the chainrings an eye-catcher.
NOTE: The matching screw covers for your Shimano Dura-Ace or Ultegra crank you can find in our shop.
