Description
It is natural to want to use steel chainrings in a steel chain and steel cog drivetrain.
Most chainrings on the market are made of aluminum, which is 35% softer than stainless steel. The softer the metal, the shorter the service lifE If you are a single speeder and you are rolling your charger on the above drive, I urge you to use Surly stainless steel chainrings made of 304 grade stainless steel.
Stainless steel is an alloy steel with particularly good toughness and corrosion resistancE As with all things mechanical, eventually things will wear out, but when they do, simply turning the chainring over will give it new lifE
Surly chainrings are best suited for single speed fixed gear or tandem timing chain applications. They are not designed for shift assist, so please note that shifting will be slightly slower when used with a front derailleur than with a regular drive system.
