HOW TO MOUNT E*THIRTEEN OVAL CHAINRING:

E*thirteen mounting instruction of a chainring

You will need E*Thirteen BB Install/Spider Removal Tool first. With this tool you need to simply open the lockring that holds the chainring on the crank. It's best to clamp that tool in a vice and Turn the crank counter-clockwise (looking from the top). Once the lockring is removed, take off old chainring and re-grease the splines on the crank. Place new oval chainring with convex side to the crank, but at the same time observing the small dimple (located next to spline interface) to be aligned with center of the crank arm. This is crucial to obtain correct chainring position. Now, place the lockring back. Since you will not be able to use torque tool, please do the following steps: Screw the lockring to the point where it starts to give you bigger resistance (as it touches the chainring now). From this point rotate the crank arm further by about 90 degrees. This will give you proper 30Nm locking force. Done

Oval (elliptical) chainring does not compromise the work of clutch mechanism in rear derailleur(video at the bottom). It also does not require chain tensioner when using in singlespeed application. These chainrings also help you to recover after knee injuries as pedaling becomes smoother and less exhausting. It is the most advanced oval chainring currently on the market.
