BMX Chains

Choose a Dependable Freestyle BMX Chain

The chain on a freestyle BMX bike has the role of transferring pedal power from the rider to the rear wheel. It must be robust and long-lasting to withstand the intensive use associated with freestyle BMX.

Comparison: Half Link vs. Single Speed BMX Chains

When it's time to replace your old BMX chain, the primary decision to consider is whether to opt for a half link chain or a single speed chain. A half link chain is crafted so each link functions as both an inner and outer link, in contrast to single speed chains that have distinct inner and outer links. Each type has its own pros and cons.

The key benefit of selecting a half link chain is the accuracy it offers in adjusting the chain length. The half links let you extend or reduce the chain by half a link at a time, allowing for fine adjustments to the rear wheel's position. However, the thicker side plates result in a heavier chain compared to the single-speed option.

The single-speed chain is the lighter variant between the two, making it the preferred choice if weight reduction is essential. This design has been utilised since bicycles were first invented, ensuring it is an exceptionally reliable option. For chain length adjustments, you can only add or remove 2½ links at a time, which limits the precision adjustments possible with half-link chains.

Which Chain Is Suitable for My BMX?

Typically, a BMX bike chain has a width of 1/8 of an inch, which is also the standard size found on freestyle BMX bikes. Some BMX racing enthusiasts favour a 3/32 or 3/16 inch width, which is a very narrow and thus a lighter chain—a significant consideration for some riders. Most freestyle bikers prefer the standard 1/8 chain.

To remove and add links to chains, chainbreakers are necessary. You can discover these along with numerous other practical items in our BMX Bike Tools section.
