Q-Rings RD3 for your triple cranks with a 130/74BCD 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, Q-Rings RD3 enable you to go farther and faster with less fatigue. Q-Rings RD3 rings offer 5 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.
