You can ride for hours at a consistent pace, which you're able to sustain by methodically turning the pedals in tune with the undulating terrain beneath your wheels. You are if nothing, consistent. You already know that nobody applies constant, even force throughout the pedal stroke, but you believe consistency is key. With a nod toward cycling´s illustrious history ROTOR wanted to complement its product range by offering you round noQX3 rings in addition to oval QX3 rings for your mountain bike. 0% ovality noQX3 chainrings for your triple cranks offer the same performance benefits inherent in traditional round rings.
