If you wish to check for frame clearance with a new oval ring, below you can find the measurement of the biggest dimension of the oval (tip to tip of a tooth):
26T: 118mm ; 28T: 127mm ; 30T: 134mm ; 32T: 143mm ; 34T: 151mm
ADVANTAGES OF OUR SPECIAL DIRECT MOUNT NARROW WIDE CHAINRINGS:
Reduces stress on knees
We mastered our oval chainrings to perfection, so you can get the best possible advantage from the oval/elliptical shape.
HOW TO MOUNT OUR OVAL CHAINRING TO SRAM GXP AND BB30 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 same mounting interface regardless of the model or axle type. The only thing you need to determine is chainring offset.
It is ideal for 1x 9/10/11/12 system and Singlespeeds!. Oval (elliptical) narrow wide 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 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 pedalling 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.
The World's best oval (elliptical) mtb spiderless traction chainring - period!. Non-circular chainrings, Non-round chainrings. Asymmetrical chainrings.
