Description


The one and only AbsoluteBlack Narrow Wide Oval Chainring Direct Mount Boost Sram 1X narrow wide round chainring is designed for bikes with a Boost format (3mm offset).

This is the most premium chainring on the market. Oval chainrings do not produce more power, they increase pedalling efficiency through better power transmission. This means that you don't necessarily get further by pedalling harder. But the less force you lose, the more energy you keep, allowing you to pedal harder when you need to and thus reducing your general fatigue. That's why you can ride faster, longer and further with oval chainrings.

Studies conducted by the University of Primorska, Slovenia, show significant differences between the use of AbsoluteBlack Oval chainrings and conventional round chainrings. It is proven that using an oval chainring can provide up to a 9% increase in pedal stroke efficiency, up to 7% less oxygen consumption, 15% less breathing and up to a 10% decrease in heart rate.

  • Unique special oval shape (patent pending).
  • Greatly improves traction and climbing ability
  • Unique alternating wide and narrow tooth profiles (patent pending) to keep your chain in place for at least 12 months!
  • Special 3D machining of the teeth for ultimate mud relief significantly reduces wear and noise.
  • They save weight because they don't need the spider and plate screws.
  • The ability to install a smaller ring size that cannot be mounted on the regular spider.
  • Exceptional quality and look.
  • You will ride faster when using ovals. If you continue to use round rings, the others will be faster.
  • You won't feel the oval shape at all.
  • Reduces stress on the knees
  • We have mastered our oval chainrings to perfection, so you can get the most out of the oval/elliptical shape.
HOW TO MOUNT OUR OVAL CHAIN ON SRAM GXP, DUB AND BB30 CRANKS :

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

* Always use a new chain with a new chainring.
