Perfect Your Setup With BMX Crank Parts

Connecting the pedals to the bike, the crankset is essential for generating forward motion on your BMX. While you can purchase a complete crankset, if you're looking to make a small adjustment or upgrade, consider buying individual parts instead.

The components that make up a crankset include the BMX crank arms, crank bolts, and a spindle. Crank arms—the levers to which your pedals attach—significantly impact your riding experience and are available in various lengths. Don't overlook the importance of having spare bolts for any urgent repairs you might need to make.

What Is a Spindle on BMX?

One of the most crucial parts of your crankset is the spindle. The spindle is the rotating axle where the cranks attach, located in the bottom bracket.

BMX spindles come in different sizes, including 19 mm, 22 mm, and 24 mm. The 19 mm diameter spindle is ideal for riding ramps, trails, and street riding. The 22 mm spindle diameter is stronger than the 19 mm and is suitable for higher drops and grinding. The 24 mm diameter has gained popularity in recent years and can handle any BMX activity you undertake.

Note that whatever size spindle you choose, you must ensure it matches the rest of your crankset.
