All new 144mm bcd chainrings from Sugino, at an affordable price point for those who aren't quite ready to shell out Zen money for a high quality Japanese chainring. 

Precision machined from 7075 T6 aluminum, the Mighty Competition Expert chainring is stiff, round, straight and smooth, as you'd expect from one of Japan's oldest manufacturers of bicycle drivetrain components.

Available in black and silver, sizes 46t-51t
