DK Chaka USA Sprocket Chainrings

Product Overview

The DK Chaka USA Sprocket Chainrings are CNC-machined aluminum sprockets designed for BMX bikes using 1/8" chain systems. Available in five sizes from 25T to 30T, they deliver consistent engagement and durability for street, park, and freestyle riding. Made in the USA with precision manufacturing, these sprockets are built to handle the demands of BMX drivetrain systems.

Key Features

• 6mm thick CNC-machined aluminum construction – Precision-cut teeth ensure consistent chain engagement with minimal wear. The 6mm thickness provides rigidity and resistance to bending under load while keeping weight minimal.
• 24mm center bore with 19mm adapter included – Fits standard BMX crank spindles directly. The included 19mm adapter allows compatibility with alternate spindle sizes, expanding mounting options.
• 1/8" tooth pitch – Standard BMX chain compatibility. Ensures proper mesh with 1/8" chains used across all BMX drivetrain setups.
• Five tooth count options (25T, 26T, 28T, 30T) – Smaller counts (25T-26T) favor acceleration and tricks; larger counts (28T-30T) suit faster acceleration and taller gearing for racing or longer distances.
• Multiple color finishes – Available in black, blue, red, silver, and purple. Color choice is purely aesthetic and does not affect performance.
