01 / MATERIALS4130 CHROMOLY STEEL
Chromoly steel is commonly used in high-quality freestyle BMX frames. It combines strength, toughness and repairability, though weight depends on tubing and design.
Not every frame offered uses chromoly. Check its specific material certificate.
02 / RACE FRAMESALUMINUM ALLOYS
Aluminum race frames often prioritize lower mass and stiffness. Performance depends on the alloy, tube dimensions, weld quality and heat-treatment process.
Exact alloy and treatment must be confirmed per model.
03 / FABRICATIONFORMED & WELDED
Depending on the frame, production may involve tube forming or butting, precision mitering, TIG welding, alignment checks, finishing and inspection.
These are general industry processes—not a claim about a particular factory.
04 / DURABILITYSTRENGTH IS TESTED
Frame durability should be assessed using appropriate fatigue, impact, load and weld inspections. No universal rider weight limit or strength rating can be stated without model-specific test data.
Ask about applicable standards, testing and permitted use before ordering.
