Stronglight 107 right crank arm: strength and reliability for your bicycle crankset

When it comes to replacing or repairing a bicycle crankset, choosing the right crank arm is essential to maintain a smooth and efficient drivetrain. The Stronglight 107 right crank arm stands out for its solid construction and compatibility with a wide range of bikes—whether road, touring, or city bikes. Let’s take a closer look at this key component, often overlooked but vital for optimal cycling performance.

What is a right crank arm ?

The right crank arm is the part of the crankset that holds the right pedal and is usually connected to the chainring. It transfers the rider’s power to the bottom bracket axle, turning the chainring and driving the bike forward through the chain.

On some cranksets—especially two-piece or single-chainring setups—the right crank arm is independent of the left, making it possible to replace just one side if damaged.
