absoluteBLACK Oval Chainring

This chainring is designed specifically for 110 BCD 4-bolt or 5-bolt FSA cranks, including the Gossamer, SL-K, and K-Force models. Please verify your crank's BCD and bolt pattern before purchasing to ensure compatibility.

The 3.5% ovality is subtle enough that most riders adapt to it within a few rides. It is designed to smooth out the 'dead spot' in your pedal stroke, which can help reduce knee strain and keep your legs feeling fresher on long climbs.

Yes, you will likely need to make minor adjustments to your front derailleur height and limit screws. Because the chainring is oval, the derailleur cage needs to be positioned correctly to maintain smooth shifting across the entire rotation.

Not at all. This chainring features specialized shift ramps specifically engineered to maintain crisp, reliable gear changes. While it may feel slightly different initially, the shifting precision remains comparable to high-quality round rings.

It is optimized for road cycling and climbing, where maintaining a consistent cadence is most beneficial. If you primarily ride flat terrain or prefer a very high-cadence spin, you may find the oval shape less noticeable, but it remains a durable and efficient upgrade.
