ABSOLUTE BLACK chainring Sub Compact oval 2-fold LK 110 4 holes asymmetrical | Dura Ace 9100 | Ultegra R8000 | black inside
With the Sub-Compact chainrings from Absolute Black you can conquer any angle with your racing bike or gravel bike! The asymmetrical 110 millimeter bolt circle diameter is suitable for all current Shimano ROAD cranks . The gear ratio variants with 48-32 and 46-30 teeth help to maintain a smooth step even on the steepest ramps.
The 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. The Sub-Compact chainrings are coordinated so that only the combinations 48-32 and 46-30 teeth are possible. Thanks to the milling of a 5 millimeter thick aluminum plate, the Absolute Black chainrings are among the stiffest on the market. The large cutouts keep the weight low and make the chainrings an eye-catcher. The oval shape smooths the force peaks during the crank rotation. 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.
NOTE: The appropriate special screws for fastening are included with the small chainring.
