Introducing the AbsoluteBlack Premium Oval Sub-Compact 110/5 BCD chainrings with the Sub-Compact size to improve your climbing and cadence.

Increased cadence is essential to reduce perceived effort. With the 48/32T chainrings, you can ride anywhere and climb anything. Alpine climbs will never be so difficult again. These special super compact chainrings are designed for Shimano 110/5bcd cranks, making AbsoluteBLACK the only company on the market offering such sizes. The 32T chainrings allow you to climb on your own terms with improved cadence and efficiency. 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 force transmission. 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.

First, you need to remove your crank from your bike. Once removed, unscrew the 5 bolts that hold two chainrings together with a T-30 torx key. Remove both original rings.
Start by placing big chainring on the crank. Please note that small triangular indicator on the inner circumference of the chainring Must sit behind the crank arm - same way as original chainring indicates its position. Next, locate triangular mark on inner circumference of the small chainring and make sure it will sit behind the crank as well. Small chainring has also an integrated spacers on one side. Those spacers need to enter into the crank mounting holes. 32T chainring is provided with 5x M5 bolts (Torx T-25). Lock both chainrings in place using provided bolts and torque to 4-5Nm
In case of Sram cranks with one hidden bolt the indicators of both chainrings have to be positioned exactly opposite to the crank arm to guarantee correct timing of the oval rings in respect to the crank arm
