Scooter bars are available in a wide array of different materials, Steel, aluminum, and titanium! Steel and aluminum being the most cost-effective and commonly bought option. Typically, available in oversized and standard diameters giving them a wide array of compression options. Aluminum being a lighter option, occasionally at the cost of strength. Often with a standard inner diameter but an oversized external. Making them great for SCS and IHC compression, but also not compatible with HIC. Titanium bars generally only come in oversized diameter, making them a perfect option for SCS. Paired with an oversized clamp titanium is also compatible with HIC and IHC. Rigorously tested, they are some of the lightest and strongest bars on the market, but typically at a steep price option. Keep in mind that cutting titanium bars is a very difficult task, often requiring state of the art equipment, and practiced techniques.
