RHD / LHD
RightHandDrive or LeftHandDrive allow you to assemble your BMX Chain onto your preferred side. That avoids interfering your sprocket at grinding, for example.
2-/3piece crank
BMX Cranks usually consist of 2 crank arms an 1 axle, which are called 3piece cranks. There are also 2piece cranks or 2.5piece cranks, where one crank arm is combined boltless with the axle. That demands only one main bolt on the other side to fix the whole BMX crank.
Microdrive
If you want to ride a BMX sprocket with less than 25 teeth, you will need a BMX crank which offers microdrive. In this case the sprocket bolt has less distance to the crank axle and needs a nearer threaded hole on the crank arm.
