QX1 76BCD chainrings for your 1x cranks take advantage of the most-productive part of your pedal stroke by working with your body´s biomechanics to yield maximum efficiency. How you transfer power off-road will vary as much from the way you ride as to where you ride; QX1 rings offer 12.5% ovality and feature 3 Optimum Chainring Positions (OCP) that can be timed to the most-powerful output in your pedal stroke while affording you instant traction and faster acceleration when you need it most.
