The chainrings of Absolute Black are CNC machined from billet aluminum and then anodized. This ensures a rigid and durable chainring. They were developed for a 1 x 10, 1 x 11 and 1 x 12 (SRAM Eagle) drives. The chainrings have special teeth that prevent the chain may come off. The principle follows that of SRAM XX1 chainrings. In conjunction with an SRAM or Type2 + Shimano Shadow derailleur, which have a greatly increased bias of the cage, the chain is held in position reliably without the chain guide.Technical specifications:
