Lighter, stronger, faster, the recipe for any great BMX Racing product!
The Supercross BMX Carbon Expert/Junior bars are a scaled-down version of our Pro bars. These are made for the ultimate little racer who requires the best tools for the job!
Featuring Monocoque T-700S High Compaction Construction, they're just as strong as our award-winning ENVY BLK race frame and BLK Forks. It receives the same time-consuming hand layup, wrapping, and molding, ensuring every set meets strict safety and quality standards.
Now available in a color-matched version to pair seamlessly with the new Supercross BMX Vision F1 Chassis Kits.

Looking for some help with the installation? Check out our blog post that breaks down the whole process.
Ensure that your stem is ROUND on the inner diameter and not ALMOND-shaped. Do not use Split type stems, and make sure you get even torque across all bolts. The Torque Spec is 10nm for stem clamping. Looking for a Torque Key?
Don’t forget the Carbon Paste, which is necessary for proper installation.
All torque specs must be adhered to for proper operation. Failure to follow these guidelines could result in subpar performance and risk of injury. It is your responsibility to check your bars for cracks after each crash. These are high-end racing bars. And the warranty is for material and manufacturing defects only. Not against use and abuse.
