The crank is the central axis on which the front chainring unit rotates. There are several aspects to consider when changing this part. Perhaps the most important thing is how the crank connects to the front chainring block. The main types at the moment are the square taper, Hollowtech, and the less frequently used Octalink. Equally important is the length of the crank and the thread standard (68mm, 73mm or others). As technology advances, cranks become stronger, lighter and provide smoother pedalling. SHIMANO cranks are used most often, but we can offer NECO and Feimin cranks as well.
