To reduce the system weight on the wheel, there is the legendary Rotor Q-Ring now available in a direct mount version for SRAM BB30 mountain bike cranks . The sophisticated ovalization of the Q-Rings increase performance by varying the drive train and optimize the resistance. While kicking his legs natural strengths and weaknesses are reconciled. So better use of the stronger muscle groups is achieved and created a balance in the travel (lower hub) in the weaker muscles. There are possible 3 different adjustments of the gears to provide optimum performance for the bikers.
The chainrings continue to have specially shaped teeth that prevent the chain may come off. 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.
