*One of a kind special oval shape (Patent Pending)
*Greatly improves traction and climbing abilities
*Unique Patent Pending alternate wide and narrow teeth profiles to keep your chain in place for a minimum of 12 months!
*Special 3D teeth machining for ultimate mud relief decrease wear and noise dramatically
*They save weight because they don't need the spider and chainring bolts.
*The ability of installation of smaller ring sizes that can't be mounted on a regular spider.
*Superb quality and great look.
*You will ride faster using ovals. If you keep using the round ring then others will get quicker.

HOW TO MOUNT OUR OVAL CHAINRING TO SRAM GXP, BB30, DUB CRANK:

You need to unscrew these 3 Torx t-25 bolts from the crank. Then remove the spider+chainring combo you currently have there. Clean the splines and put some grease on them. Position the chainring in place (note there is only one way to fit this chainring to Sram crank, so you don't have to worry how to do it). Close all 3 bolts to about 5-7Nm.

Check below which Sram compatible oval chainring you will require for your Sram crank type. All Sram Cranks have exactly the same mounting interface regardless of the model or axle type. The only thing you need to determine is the chainring offset.

BB30 sram chainrings and axles explained

It is ideal for 1x 9/10/11/12 system and Singlespeeds!. Oval (elliptical) chainring does not compromise the work of the clutch mechanism in rear derailleur(video at the bottom). It also does not require a chain tensioner when using in the single-speed application. Riding out of the saddle on the uphill will become more pleasant. 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.

The most advanced, Patent Pending alternate wide and narrow teeth profile currently produced, guarantee a minimum of 12 months of excellent chain retention capabilities! We mean it. Always use a new chain with a new chainring.

Chain options

10, 11 or 12spd chain for a geared bike or 6-8 spd for SS. If used in 1x9 drivetrain - a 10spd chain must be used to obtain the performance. (yes - 10spd chain will work great on 9spd cassette)
