ABSOLUTE BLACK chainring Oval 1 times XTR M9000 LK 96 narrow-wide | black
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 9, 1 x 10, 1 x 11 or 1 x 12 (SRAM Eagle) drive. The chainrings have special teeth that prevent the chain may come off. The principle follows that of SRAM XX1 chainrings. In conjunction with a Sram or Shimano Shadow Type2 + derailleur, which have greatly increased bias of the cage, the chain is reliably held in place without chain guide.
The ovalization of the rear sprocket increases performance by variation in the drive train and optimizing the resistance. When contact with the legs, the natural strengths and weaknesses to be reconciled. To make better use of the stronger muscle groups is achieved, creating a balance in the working path (lower hub) in the weaker muscles.
