ROTOR chainring Q-Ring Direct-Mount for Rotor Rex cranks
In order to reduce the system weight on the bike, the legendary Rotor Q-Ring is now also available in a direct mount version for the Rotor REX 1.1 / 2.1 cranks . The ingenious ovalization of the Q-Rings increases performance through variation in the drive train and optimization of resistance. When kicking with the legs, the natural strengths and weaknesses are brought into line. This achieves better use of the stronger muscle groups and creates a balance in the weaker muscles on the way to work (less stroke). There are 3 different adjustments of the chainrings possible to create an optimal performance for the biker.
The chainrings also have specially shaped teeth that prevent the chain from jumping off. In conjunction with a Sram Type2 or Shimano Shadow+ rear derailleur, which have a greatly increased preload on the cage, the chain is reliably held in position even without a chain guide.
