If your drivetrain pairs a steel chain with steel cogs, a steel chainring is the obvious choice. Most chainrings on the market are aluminum, which is roughly 35% softer than stainless steel, leading to faster wear. The Surly Stainless Steel Chainring is crafted from 304-grade stainless steel, providing exceptional toughness, rust and corrosion resistance, and extended lifespan. When the teeth wear, simply flip the chainring to continue riding with nearly a full second life.

Designed for single-speed, fixed gear, and tandem timing chain applications, this chainring is not ramped or pinned, so front-derailleur-assisted shifting will be slower—but durability is king.
