ABSOLUTE BLACK chainring CX oval | narrow wide 1-way LK 110 5 holes | Gray
Absolute Black's chainrings are CNC-milled from one piece of aluminum, creating the perfect combination of low weight and excellent durability for your bike. 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.
The CX chainrings with an asymmetrical 110 millimeter 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 conjunction with a SRAM Type2 or Shimano Shadow + rear derailleur, which have a greatly increased cage preload, the chain is reliably held in position even without a chain guide.
