QX3 chainrings for your triple cranks with 104/64BCD feature subtle 10% ovality to give you a little something extra. By distributing the work more efficiently between muscle groups across a broader range of gears, QX3´s enable you to go farther and faster with less fatigue. QX3 rings offer 3 Optimum Chainring Positions (OCP), which can be adjusted to take advantage of your pedal stroke's most-productive zone to propel you forward on each rotation.
