ABSOLUTE BLACK Chainring oval 1-speed LK 64 | narrow wide black

ABSOLUTE BLACK chainring Oval 1 times LK64 | narrow wide black

Absolute Black chainrings are CNC machined from billet aluminum and then anodized. The result: An extremely rigid and durable chainring. They were developed for a 1 x 9, 1 x 10, 1 x 11 and now new 1x12 for the drive. 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 Type2 / 3 or Shimano Shadow rear 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.
