If you would like to check the frame clearance with a new oval ring, below you can find the measurement of the largest dimension of the oval (prong tip to prong tip):

30T: 134mm; 32T: 143mm

Advantages of our special direct mount plates:

* Best design to provide excellent weight/strength ratio
* min 12% lighter than the common round plate
* Special one-of-a-kind oval shape (patent pending)
* Greatly improves traction and climbing skills.
* Unique patents with narrow and wide tooth profiles to keep your chain in place for a minimum of 12 months!
* Special 3D tooth machining for the best mud relief reduces wear and noise dramatically
* Excellent quality and great looks.
* You will ride faster using ovals. If you keep using the round ring, the others will get faster.
*You won't 'feel' the oval shape at all
* Reduces stress on the knees.
* We master our oval chainrings to perfection, so you can get the best possible advantage of the oval/elliptical shape.

You will need E*Thirteen BB Install/Spider Removal Tool first. With this tool, you simply need to open the lock ring that holds the chainring on the crank. It's best to hold that tool in a vice and turn the crank counterclockwise (looking from the top). Once the lock ring is removed, remove the old chainring and re-grease the splines on the crank. Place a new oval chainring with convex side on the crank, but at the same time watch the small dimple (located next to the slot interface) to align it with the center of the crank arm. This is crucial to obtaining the correct plate position. Now, put the lock ring back on. Since you won't be able to use the torque tool, follow these steps: Screw in the lock ring to the point where it starts to give you more resistance (since it's touching the chainring now). From this point, turn the crank arm a little more than 90 degrees. This will give you a proper locking force of 30 Nm. Made


The oval (elliptical) chainring does not compromise the work of the clutch mechanism in the rear derailleur (video at the bottom). It also does not require a chain tensioner when used in single speed applications. These chainrings also help you recover after knee injuries as pedaling becomes smoother and less tiring. It is the most advanced oval chainring currently on the market.
