What Is A Narrow Wide Chainring?
The term "narrow wide" chainring describes the shape and profile of the individual teeth driving the chain. Each tooth alternates thickness, narrow wide narrow wide, all the way around the ring.

Chainguides have become smaller, lighter, and more streamlined since narrow wide chainrings have taken off.
