Drivetrains
A BMX race drivetrain — including the chain, chainring, cogs, cranks, and bottom bracket — is the system that turns your pedal power into speed. Every component must work together smoothly for maximum efficiency and performance. A well-maintained drivetrain delivers crisp, reliable power transfer for explosive starts and high-speed sprints. Worn or poorly set-up parts can cause skipping, drag, or mechanical failure. In BMX racing, a quality drivetrain is essential for turning every ounce of effort into forward momentum and keeping you competitive from start to finish.
