ABSOLUTE BLACK chainring CX oval | narrow wide 1x LK 110 5 holes | black
Absolute Black chainrings are CNC machined from a single piece of aluminum, creating the perfect combination of low weight and excellent durability for your bike. The oval shape smooths out the power peaks during the crank revolution. As a result, you have a more even step, especially on the mountain, and your muscles tire less. The lower force peaks also reduce the stress on the knees.
The CX chainrings with an asymmetrical 110 mm 5-hole mount have been designed for all cranks with the classic compact bolt circle diameter . With 38 - 42 teeth, they are ideal for use on cyclocross bikes.
The chainrings have special teeth that prevent the chain from jumping off. The principle follows that of the SRAM XX1 chainrings. In connection with a SRAM Type2 or Shimano Shadow+ rear derailleur, which have a greatly increased preload of the cage, the chain is reliably held in position even without a chain guide.
