ABSOLUTE BLACK chainring Road Oval 2x LK 110 4 hole asymmetric | black inner
The chainrings from Absolute Black are CNC-milled from a single piece of aluminum, creating the perfect combination of low weight and excellent durability for your bike. The oval shape smoothes the power peaks during crank rotation. This gives you a smoother pedal stroke, especially on hills, and reduces muscle fatigue. The lower power peaks also reduce the strain on the knees.
Note: The illustrations show the previous version for Dura Ace 9000 and Ultegra 6800 cranks.
