This is BLUE LUG's original "FAT SLIM CHAINRING" for front single chainrings. The teeth of different thickness are alternately arranged to fit the gap between the links to hold the chain firmly and prevent it from falling off.
The simple design with no conspicuous logo makes it easy to match with any crank design.
