Description

AbsoluteBlack Premium 1X Cyclocross 110/4 BCD oval chainrings are designed specifically for APEX 1 cranks that have an asymmetrical 110/4BCD screw pattern. They are not compatible with other cranks. Narrow and wide chainring design. Use original Sram bolts. This is the most premium oval chainring on the market with scientifically proven performance gains.

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

ADVANTAGES OF THE NARROW WIDE ABSOLUTEBLACK OVAL CHAINRING :

We have mastered our oval chainrings to perfection, so you can get the best possible benefit from the oval/elliptical shape.
Thinnest design to provide an excellent strength to weight ratio.
Unique special oval shape (patent pending).
Greatly improves traction and climbing ability: better transmission of forces to the rear wheel.
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 to dramatically reduce wear and noise.
Superb quality and great looks.
You will ride faster when using ovals. If you continue to use round rings, the others will become faster.
You won't feel the oval shape at all.
Prevents knee problems: less stress on knee tendons when pedalling
The oval helps to keep lactic acid at bay.
The narrow and wide oval (elliptical) chainring does not compromise the function of the rear derailleur clutch mechanism. It also does not require a chain tensioner when used in single speed.
Riding out of saddle on the uphill will become more pleasant.
