FSA 1x11-speed, 4 arm, 76mm ABS (Asymmetric Bolt Spacing) BCD chainring for Afterburner Compact MegaExo cranks MY 2016! Its special thick-thin tooth design (Megatooth) provides maximum chain engagement. Made of precision CNC machined 7075 aluminium. Finish - arms: CNC machined, rest: bead blasted and black anodized.

This allows for smooth chain engagement, meaning that the chain always remains in close contact with the chainring to give you the most reliable and positive drive possible.
