The choice for the right BMX Pedals could be hard for you. Magnesium, Aluminum and Plastics are the materials. And then you can also choose between normal or industrial bearing and the right color. Especially the color should be really hard to choose when you consider plastics pedals because the variety is so great. Please be aware that there are different axle diameters for pedals: 9/16" für 3 part cranks, 1/2" for 1 part and sometimes for cheap more part cranks.
