ABSOLUTE BLACK chainring Premium Oval Road 2-speed LK 112 4 holes | Campagnolo cranks | black inside 39 teeth
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. 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, the Absolute Black chainrings are among the stiffest on the market. Due to the large cutouts, the weight is kept low and they make the chainrings an eye-catcher. The oval shape smoothes the force peaks during the crank rotation. This gives you a more even kick, especially on the mountain, and the muscles are less tired. The lower force peaks also reduce the strain on the knees.
