  • Unique Patent Pending narrow-wide tooth profiles to keep your chain in place even in aggressive conditions
  • Special 3D teeth machining for ultimate mud relief, decreased wear and noise
  • Designed to handle the rigors of mud and grass
  • Lower weight by reducing the need for a spider and chainring bolts
  • Superb quality and look.
  • Riders will not "feel" the oval shape
  • Improves traction and climbing abilities
  • Reduces knee stress


Take the crank off the bike. Unscrew these 3 torx t-25 bolts from the crank arm. 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 Sram chainring so you don't have to worry how to do it). Close all 3 bolts to about 5-7Nm.

It is ideal for 1x systems and Singlespeeds!. Oval (elliptical) chainring does not compromise the work of clutch mechanism in rear derailleur. It also does not require chain tensioner when using in singlespeed application. Riding out of 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.

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

Designed in UK. Manufactured in Poland (EU).

Chainguide needed?

No. But if you want one then chain guide should have 2 teeth more capacity than nominal oval ring size.
