Description

The one and only AbsoluteBlack Narrow Wide Oval Chainring Direct Mount Boost Race Face 12 S in Rainbow PVD color (oil slick). Designed for Direct Mount Race Face Cinch cranks. This special PVD Rainbow Titanium coating process makes the chainrings very durable and incredibly beautiful. 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 force transmission. 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 OVAL CHAINRING :
  • Thinnest design to provide excellent strength to weight ratio.
  • 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 chainring bolts.
  • 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 knee wear.
  • We have mastered our oval trays to perfection, so you can get the most out of the oval/elliptical shape.
HOW TO MOUNT THE ABSOLUTEBLACK OVAL CHAINRING ON THE RACEFACE CINCH CRANK :

The chainring has a mark on the back that you need to align with the centre of the crank arm to get the main/recommended position. Once this is done, use the BB key to lock the chainring. If you wish to try a more aggressive setup, rotate the chainring from the main position clockwise one notch on the splines. This will rotate the oval an additional 22 degrees. We do not recommend the second position for beginners. Before you start experimenting with the chainring synchronization, make sure you have been riding in the main position for at least 5 months.

NOTE : Due to the nature of the PVD process, each platter is unique and the colour may vary. No two trays are the same, making your new tray completely unique.
