QX2 chainrings for your double 110/74BCD cranks feature subtle 10% ovality that can be dialed in to take advantage of the most-powerful part of your pedal stroke to give you faster acceleration and better traction on whatever terrain you thrust under your wheels.
QX2 rings give you 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.
