Chainrings

Bike chainrings are the toothed front parts of the crankset that convert the cyclist's power into traction, ensuring smooth and efficient shifts. Made from durable materials such as steel, aluminum, or carbon, they are designed to last thousands of kilometers before showing signs of wear. Certainly, bike chainrings also wear out, presenting the so-called "shark fin" teeth: they have a tapered and pointed shape, and can no longer ensure an effective engagement with the chain and therefore a safe shift of the rear derailleur. 

To choose the most suitable chainring, it is essential to evaluate: compatibility with the drivetrain (number of speeds and BCD mounting system), the possibility of using different shapes (round, oval, or narrow-wide) depending on the use - road, MTB or gravel - and the possible presence of specific systems such as direct-mount to improve chain guidance.
