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. The oval shape smoothes the force peaks during the crank rotation. As a result, you have a more even kick, especially on the mountain, and your muscles are less tired. The lower force peaks also reduce the load on the knees.

The Gravel chainrings with asymmetrical 110 mm 4-hole mount have been designed for Shimano racing bike cranks . With 44 – 50 teeth, they are ideal for use on Gravel Bikes.

The chainrings have special teeth that prevent the chain from jumping off. The principle follows that of the SRAM XX1 chainrings. In conjunction with a SRAM Type2 or Shimano Shadow + rear derailleur, which have a greatly increased bias of the cage, the chain is reliably held in position even without chain guide.

NOTE: Contrary to the picture, the chainring is delivered in gray.Technical specifications:
