The bicycle crankset and chainrings are one of the most important bicycle transmission components of the bike, together with the bottom bracket and pedals allow our force applied in the movement of the legs is transmitted to the chain and therefore to the rear sprocket or cassette to move the wheel, so the whole set of components of the bicycle is known as transmission and it is crucial to pay attention to the quality of these parts.

Take into account the use you are going to give to the cranks, if you need to have a more or less intense or sporty pedaling, since the diameter of the chainring, defined by the number of teeth (for example, 44T chainrings refers to a 44-tooth chainring), the number of chainrings (there are cranksets with a multitude of chainrings) and the length of the crank will determine the intensity of the pedaling, also make sure of the compatibility with the bottom bracket or bottom bracket shell as it may be a square, keyed or other systems, if you have a very old axle is very likely to be keyed, it is advisable to change to a square axle to ensure greater compatibility in the future.
