AbsoluteBlack Premium Oval Chainrings 112/4 BCD for Campagnolo Transmissions 12S Black
absoluteBLACK
Description
AbsoluteBlack Premium Oval Chainrings 112/4 BCD for Campagnolo 12 S, designed for Super Record, Record and Chorus cranks with 4 screws 112 BCD. They work perfectly with 11 and 12 V transmissions thanks to an ingenious design. Incredibly rigid and light. Super fast shifting thanks to the patented shift ramp design. It's 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.

- We have mastered our oval chainrings to perfection, so you can get the most out of the oval/elliptical shape.
- Remove the crank from the bike. First unscrew the screws of the small chainrings with a T-30 Torx spanner. Campagnolo uses a hard glue, so you may have to force the screws to turn. Then remove the large chainring with the same spanner. Mount our oval chainrings in the same way as the originals, noting that the small indicator triangle on the inner circumference of both chainrings must be aligned with the crank arm. Tighten the 8 screws to a torque of about 5-7 Nm.
