Bike cranks, also known as cranksets or chainsets, are at the heart of every bicycle drivetrain. They connect the pedals to the chainrings, converting your pedalling force into forward motion. Choosing the right set of cranks affects power transfer, gearing range, weight, and even comfort on long rides. Whether you ride road, MTB, gravel, BMX or commuter bikes, upgrading or replacing your cranks can significantly improve performance and reliability.
