Key Features

• 72-Link Length – Compact chain length suitable for frames with shorter chainstays or custom drivetrain configurations. Allows precise length matching for specific frame geometries without excess material or weight.

• 1/2" x 1/8" Pitch – Standard BMX chain pitch compatible with all single-speed and multi-speed sprockets and chainrings. Direct compatibility with common BMX drivetrain components.

• Nickel Finish – Corrosion-resistant nickel coating protects against rust and oxidation through wet conditions and extended exposure. Nickel maintains appearance and extends chain service life.
