Rotor Q-ring MTB SRAM XX-X0-X9 80bcd 9/10sp chainring

This is the moment when the cranks are vertical. No power can be applied at this point so you want to get over this point as quickly as possible. Rotor Q-Rings have fewer gears at the dead point so you get over the dead point faster. Then it has maximum resistance at the point where you get the maximum force out of a revolution. Because of this theory, you get over the dead point faster so you reach the point of maximum power explosion with less power loss. This makes for more efficient pedaling which results in less lactate and fatigue.
