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 110/74BCD rings in addition to oval Q rings for your mountain bike. 0% ovality noQX2 110/74BCD chainrings offer the same performance benefits inherent in traditional round rings.https://rotorbike.com/catalog/media/catalog/product/C/0/C01-503-21010A-0-FAA_5_7.jpg29.99instock29.9929.9900000https://rotorbike.com/catalog/media/catalog/product/C/0/C01-503-21010A-0-F01_16_2.jpg/ROTOR/ROTOR/Previous Ranges
