Product Information

Full details

The AbsoluteBLACK Premium Road Oval chainring is designed for road cyclists using pre-2014 cranksets who want to improve pedaling smoothness and climbing efficiency. By utilizing a 10.3% ovality, this chainring helps maintain momentum through the dead zone of the pedal stroke, offering a more natural feel for seasoned riders; however, it requires a compatible 110/5 BCD crankset and is not intended for cranksets with a hidden bolt configuration.

FAQs

Is this chainring compatible with SRAM hidden-bolt cranks?

No, this specific model is not compatible with cranksets that use a hidden bolt design.

Will this work with my electronic shifting system?

Yes, this chainring is fully compatible with Shimano Di2 and other electronic shifting systems.

How long does it take to get used to the oval feel?

Most riders adapt within the first few rides as the natural biomechanics of the pedal stroke feel smoother.

Does the 50T ring require a specific inner ring?

It is recommended to pair this with an AbsoluteBLACK inner oval ring for the best shifting performance, such as the 34T variant.

What is the BCD of this chainring?

This chainring features a 110mm BCD with a 5-bolt pattern.

Can I use this on a newer 2016 model crankset?

This model is optimized for pre-2014 crankset standards; please check if your crank uses a hidden bolt, as that will determine compatibility.

Troubleshooting

Poor shifting performance

Verify that your front derailleur height and angle are correctly adjusted to the oval profile and check that the chainring is clocked correctly according to the timing marks.

Chain rub on front derailleur

Adjust the front derailleur limit screws slightly, as the variable radius of an oval ring may require a wider cage clearance than a perfectly round ring.

Pros and Cons

Pros

  • Significantly smoother pedal stroke
  • Improved efficiency during steep climbs
  • Seamless integration with Di2 electronic shifting
  • High-quality precision machining
  • Natural adjustment period for riders

Cons

  • Not compatible with modern hidden-bolt cranksets
  • Limited to pre-2014 crank standards
  • Requires proper timing alignment during installation

Setup, Compatibility & Care

Ensure your current crankset uses a 110mm BCD with a 5-bolt mounting pattern, excluding any models that utilize a hidden-bolt design behind the crank arm. To install, align the timing mark on the chainring with the crank arm per the manufacturer's specific orientation instructions to ensure the 108-109.5 degree timing is achieved. Maintain the chainring by cleaning it with a non-abrasive degreaser during your regular drivetrain maintenance. Always check for chain wear, as an older or stretched chain can lead to premature tooth wear on the oval profile.
