3. Rider Usage

The products you buy should match your skill level and the tricks you practice. Some parts are designed to handle more stress and some parts are designed to be more economical. If you are doing big gaps, do your research and do not buy a lower level product. Compare your current set of tricks with the ones on the chart to figure out what skill level of bike or product you need.

These skill icons are located below products on the site to show what kind of abuse these parts are designed for.

4. Steel vs Chromoly

 

Q: IS 1020 STEEL GOOD ON A BMX BIKE FRAME?
A: Yes, 1020 steel is excellent for bike frames. 1020 steel means it's high tensile steel, as in strong! Steel has been the material for the majority of bike frames for over 100 years because of its high strength, ease of repair and low cost.

Q: WHAT ARE THE DIFFERENCES BETWEEN 4130 CHROMOLY, REGULAR CHROMOLY (CROMO) AND 1020 STEEL?
A:
1020 Steel - slightly heavier frame due to slightly thicker tubing. High-strength drawn / extruded tubing made of recycled steel.
Regular Chromoly - Lighter than 1020 steel but about the same strength. Standard strength welded tubing made of recycled steel + extra metals for added strength. The tubing can be made thinner because of the added strength. The frame comes out
4130 Chromoly - Lighter and stronger than regular chromoly (cromo) and 1020 steel. Made of high-strength drawn / extruded tubing made from highest quality and strength virgin ore.
