Durable Narrow Wide steel chainring from Bikepartner, compatible with 1-11 speed.

Why choose a steel chainring?

Studies and tests show that steel chainrings typically have a lifespan 3-4 times longer than regular aluminum chainrings, which are often the type found on factory electric bikes. This is because aluminum is a softer material, making it more prone to wear and tear. Additionally, steel chainrings maintain consistent performance from installation until it's time for replacement. Steel chainrings are also usually more budget-friendly than their aluminum counterparts.

Since the entire drivetrain, from chainrings to the chain and cassette, is interconnected, using steel chainrings can result in a longer lifespan for the cassette and chain as well. A worn chainring will wear down both the cassette and chain, necessitating faster replacements for optimal performance.

One drawback of steel chainrings is their weight, as they typically weigh about twice as much as a comparable aluminum chainring. However, due to the generally higher weight of electric bikes compared to, for example, road bikes, it makes sense to consider whether one can accept a bit more weight in the chainrings in exchange for a longer lifespan for the entire drivetrain.
