BMX Cranks are 2 metal arms that connect to the bottom bracket of your bike. Once the crank arms are connected, we then screw on the pedals which allow riders to push forward and catch speed when riding. Freestyle BMX cranks are usually made out of steel or chromoly rather than aluminium or carbon fiber in order to provide riders with maximum strength and support.
Different Types of Crank-Sets
There are three different types of crank-sets for freestyle BMX's which are the 1-Piece, 2-Piece and 3-Piece cranks.
The 1-Piece cranks tend to appear mostly on either the older models or entry level bikes. 2-Piece cranks come with a crank bolt and are extremely easy to install. These cranks contain a spindle that is attached to one of the crank-arms. 2-Piece crank-sets are usually found in the intermediate level bike models. 3-Piece cranks are the most common out of the 3 and usually found on Pro models. In most cases, these cranks are slightly heavier than the standard 2-Piece cranks however, they are a lot more solid.
