The BMX chain might just be the most important part of your BMX. Without it, you can't pedal!
Whether it's a standard chain, a half link BMX chain or a BMX race chain, you'll find it in our selection of the best BMX chains.
What size is a BMX chain?
The majority of BMX chains - both traditional and half-link - come in a half inch (1/2") length. BMX chain width has two options, 3/32" and 1/8". This is why you see the sizing 1/2" x 1/8" or 1/2" x 3/32" (denoting the length x width of one chain link).
BMX chains with a 1/8" width are wider and generally stronger, which are used on the majority of freestyle BMX bikes, as well as some BMX racing bikes. The 3/32" width is a weight saving option for BMX racers, requiring a sprocket and rear driver of the same width.
All chains come with an 96+ links, so a chain breaker tool must be used for shortening to the correct size.
