ABSOLUTE BLACK chainring Road oval Premium 2x LK 110 4 hole asymmetric | Dura Ace 9100 | Ultegra R8000 | PVD rainbow inner
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 shifting ramps ensure excellent shifting performance. For maximum shifting efficiency, the chainrings should be combined with the correspondingly optimized large chainring (53-39, 52-38/36, 50-34).Thanks to the milling from a 5 millimeter thick aluminium plate, the Absolute Black chainrings are among the stiffest on the market. The large cut-outs keep the weight low and make the chainrings an eye-catcher. 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 your knees. Thanks to the special PVD Rainbow Titanium coating process, the chainrings are very durable and each one is incredibly individual in terms of color.
