We offer cranks both with and without chainrings. Individual crank arms allow maximum customization as you can choose chainrings and spiders to suit your needs. Cranks can be roughly divided into mountain bike, touring and racing bike categories. The most important factor when buying a crank is matching the axle to the bottom bracket. To be on the safe side, it is best to choose models from the same manufacturer and technology as they are designed to work together. You should also pay attention to how many chainrings the crank is suitable for and what bolt circle standard it has. Cranks also come in different lengths so you can choose the correct size for your leg length and riding style.
