Some of the finest chainrings available, regardless of shape, are manufactured by AbsoluteBLACK. This oval model for gravel bikes features a breathtaking "honeycomb" design sure to turn heads. This model is designed for 1x, single-chainring gravel bikes and uses the modern 4-bolt Shimano crankset mounting pattern.
Shave grams by switching your gravel bike to a 1x drivetrain. You also get easier maintenance and cleaning. Many athletes are switching their gravel bikes to 1x drivetrains to simplify maintenance and save weight. This ring was designed specifically for gravel riding with special 3D machined teeth for mud shedding and to reduce noise.
Asymmetrical (elliptical) rings work because riders don't produce power evenly throughout the pedaling stroke. Oval chainrings help normalize that power delivery to the drivetrain, so you go faster with less fatigue. A more consistent cadence can also improve rear tire traction on loose, slippery terrain.
Works with Shimano 4-bolt "road" cranksets including Dura-Ace 9100, 9120, 9000, 9020, Ultegra R8000, 8020, 6800, 105 R7000, 7020, 5800, and Tiagra 4700. Works with 10, 11, and 12 speed chains including Eagle. Does not work with GRX cranksets.
Remove the original chainring(s) from your crankset. Position the AbsoluteBLACK oval replacement chainring in the space where the big chainring was (outside position). The small triangle mark on your new AbsoluteBLACK chainring sits behind the crankarm. Install using the bolts included with the new chainring and a T-30 torx wrench (not included) with a force of 5-7Nm. Always use a new chain with a new chainring.
