Full Speed Ahead SLK ABS Road Chainring

This chainring uses FSA's specific ABS (Asymmetric Bolt Spacing) 110mm pattern. While it fits the 110mm diameter, it is designed specifically for FSA's hidden bolt cranksets and will not fit standard symmetric 110mm BCD cranks.

No, this chainring is optimized specifically for 10 and 11-speed drivetrains. Using it with a 12-speed system may result in poor shifting performance and increased wear due to the different chain width requirements.

ABS stands for Asymmetric Bolt Spacing. It means the bolt holes are not evenly spaced around the circle, which is a design feature of specific FSA cranksets to improve stiffness and power transfer. You must align the chainring correctly with the crank arm during installation.

No, this is specifically designed as an outer chainring. It features the necessary shifting ramps and pickup pins on the inner face to facilitate moving the chain up from an inner ring, but it lacks the profile required to function as the inner ring itself.

The anodized finish is highly durable and resistant to corrosion, but like all aluminum chainrings, the finish on the teeth will eventually show wear as the chain makes contact. The black coating on the main body of the ring, however, is designed to maintain its aesthetic for a long service life.
