Cassette Hubs for BMX
The main option to ensure you get correct when choosing a new cassette hub for BMX is the drive side. Most hubs are available in left hand drive (LHD) or right hand drive (RHD). This reflects which side of the bike your chain and sprocket are on when you are stood over your bike. There are some cassettes which will work for both RHD and LHD set ups, normally called a switch drive system (SDS). Check your current hub to ensure that you are ordering the correct hub.
