Stainless Steel Chainrings

Description |

On a drivetrain with a steel chain and steel cogs, a steel chainring might seem like a logical choice. Most chainrings are made from aluminum, which is 35% softer than stainless steel and, therefore, wears out more quickly. That's why Surly created the Stainless Steel chainring, crafted from tough, rust-resistant 304-grade stainless steel. While it will eventually wear out like any mechanical part, you can simply flip it around for double the lifespan.

The Surly chainring is perfect for single-speed, fixed gear, or tandem timing chain setups. Keep in mind that it’s not ramped or pinned for shifting assistance, so shifts might be a bit slower when used with a front derailleur.
