Your hard-earned technical skills have won you races and enabled you to match pace with your fitter, less-skilled riding buddies...but they´re gaining on you with their improved technique. You need a new strategy to maintain your edge. 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 noQX2 rings in addition to oval QX2 rings for your mountain bike. 0% ovality noQX2 chainrings offer the same performance benefits inherent in traditional round rings.
