Oval chainring for cranks with 104 mm bolt circle diameter . The ingenious ovalization of Q-Rings increase 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. There are 3 different adjustments of the chainrings possible to provide optimum performance for the bikers. The chainrings have specially shaped teeth that prevent the chain may come off. 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.
