Description


The AbsoluteBlack Narrow Wide Direct Mount Oval Chainring CX is designed for Sram cranks where the spider can be replaced by a direct mount chainring. The perfect choice for Cyclocross and Gravel with Sram cranks. This is the most premium oval chainring on the market with scientifically proven performance gains.

Oval chainrings don't produce more force, they increase pedaling efficiency through better transmission of forces. This means that you won't necessarily go further by pedaling 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.

ADVANTAGES OF OUR DIRECT MOUNT OVAL CHAINRINGS :
  • The most advanced patent-pending tooth profile guarantees a minimum of 12 months of excellent chain retention capabilities.
  • Thinnest design for excellent strength to weight ratio.
  • The oval chainring does not compromise the operation of the rear derailleur clutch mechanism. It also does not require a chain tensioner when used in single speed. 
  • Unique special oval shape (patent pending)
  • Unique narrow and wide 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 reducing wear and noise.
  • Designed to handle mud and grass with ease.
  • They save weight because they don't need the spider and deck bolts.
  • Superb quality and great looks.
  • You will ride faster using ovals. If you continue to use round rings, the others will become faster.
  • You won't feel the oval shape at all.
  • These chainrings also help you recover from knee injuries, as pedaling becomes smoother and less strenuous.
  • Riding uphill out of the saddle will become more enjoyable. 
HOW TO MOUNT THE CX OVAL CHAINRING ON THE SRAM CRANK :

Remove the crank from the bike. Unscrew these 3 t-25 torx bolts from the crank arm. Then remove the spider + chainring combo you currently have. Clean the splines and put some grease on them. Position the chainring in place (note that there is only one way to mount this Sram chainring, 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.
