Today, we’re taking a closer look at a standout model: the YBN MK918 1/2" x 1/8" blue half-link BMX chain — a blend of cutting-edge design and bold style built for demanding riders.

A Blue BMX chain that makes a statement

  Perfect for ultra-precise chain tension adjustment, especially on single-speed setups. Allows you to dial in your chain line without repositioning your wheel.

  Despite its durability, the MK918 remains relatively light, helping keep your bike nimble and responsive.

Why choose a half-link chain ?

A half-link chain offers greater adjustment precision than traditional full-link chains. On a BMX, where chain tension and rear wheel placement directly affect leverage and trick execution, that fine-tuning is essential. The smaller spacing between links means you can fine-tune your chain tension without compromising alignment or chainstay length.

BMX drivetrain: reliability comes first

In BMX riding, the drivetrain takes a serious beating. Every pedal stroke delivers a sharp burst of force through the crankset, chain, sprocket, and rear hub. That’s why you need a chain that’s up to the task: tough, trustworthy, and built for impact.

The YBN MK918 delivers just that — with high tensile strength, smooth engagement, and long-term durability. It’s made for riders who demand both mechanical performance and bold aesthetics.
