Description


Introducing the AbsoluteBlack Premium Oval Sub-Compact 110/4 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 and 46/30T 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 110/4bcd cranks, making AbsoluteBLACK the only company on the market offering such sizes. The 30 and 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.

ADVANTAGES OF ABSOLUTEBLACK SUB-COMPACT OVAL CHAINRINGS :
  • The 30 and 32T chainrings allow you to climb within your own physical means with improved cadence and efficiency.
  • Unique oval shape helps you climb easier and faster (patent pending).
  • No more long climbs where you want a bigger cassette.
  • 46/11 or 48/11 are still big gears to ride on the flat. For your daily rides, you probably don't need more.
  • Your pedaling will be smoother.
  • The AB oval reduces the stress on your knees and helps your legs stay cooler for longer.
  • You will be able to maintain a better cadence when climbing.
  • Reduces the risk of leg cramps.

HOW TO MOUNT THE SUPER COMPACT 46/30T & 48/32T 110/4 OVAL CHAINRINGS :

First of all, you need to remove your crank from your bike. Once removed, unscrew the 4 screws that hold the two chainrings together with a T-30 torx key. Remove the two original rings.for 46/30T - Start by placing the large chainring on the crank. There is only one way to do this. Next, locate the triangular mark on the inner circumference of the small chainring and ensure that it will be placed behind the crank. The small plate also has built-in spacers on one side. These spacers must fit into the mounting holes of the crank. The 30T chainring is supplied with 2 M5 screws (Torx T-25) and 2 M7 screws (Torx T-30). Lock both chainrings in place with the screws provided and tighten the M5 screws to 4-5 Nm and M7 to 5-7 Nm for 48/32T. The same procedure applies except that the 32T chainring is supplied with 4 M7 screws (Torx T-30).
