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.
