Every pedal rotation has a single purpose: to propel you forward. You already know that nobody applies constant, even force throughout the pedal stroke, but you believe consistency is key. With a nod toward mountain biking´s relatively recent beginnings, ROTOR wanted to complement its product range by offering you round noQX1 76BCD rings in addition to oval Q-Rings for your mountain bike. 0% ovality noQX1 chainrings for your 1x cranks offer the same performance benefits inherent in traditional round rings.
