ABSOLUTE BLACK chainring oval 1x LK64 | narrow wide black
Absolute Black chainrings are CNC-milled from a single piece of aluminium and then anodized. The result: an extremely stiff and durable chainring. They were developed for a 1x9, 1x10, 1x11 and now for the 1x12 drivetrain. 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 Type2/3 or Shimano Shadow+ rear derailleur, which have a greatly increased cage preload, the chain is reliably held in position even without a chain guide.
The ovalization of the chainring increases performance by varying the drivetrain and optimizing resistance. When pedaling with the legs, the natural strengths and weaknesses are harmonized. This results in better use of the stronger muscle groups and compensates for the weaker muscles in the work stroke (shorter stroke).
