BMX half link chain: precision tuning for your drivetrain
The BMX half link chain is gaining popularity in the world of freestyle and street BMX—and for good reason. It offers unbeatable advantages when it comes to fine-tuning chain tension, boosting durability, and upgrading the look of your setup. Whether you ride park, street, or dirt, here’s everything you need to know about this essential bike drivetrain component.
What is a BMX half link chain ?
Unlike a traditional bike chain made up of full links, a half link chain alternates between a half link and a full link. This allows for more precise length adjustments and better chain tension, especially on BMX bikes with horizontal dropouts.
The benefits of a half link chain
-
Millimeter-level adjustment: Half links allow you to dial in the position of your rear wheel without needing to remove two full links at a time.
-
Perfect chain tension: A properly tensioned chain avoids skipping and ensures maximum power transfer when pedaling.
-
Ideal for single-speed drivetrains: Perfect for BMX setups without a derailleur, keeping your sprocket and chainring in perfect alignment.
-
Built for impact: Half link BMX chains are usually heavier but stronger, able to withstand hard landings, grinds, and street abuse.
Key technical features
Here’s what to look for when choosing a BMX half link chain:

-
Clean it often with a proper degreaser,
-
Lubricate it with a chain-specific oil,
