The all-new SV-F collection, which utilizes advanced flow formed technology. These wheels are our strongest and lightest wheels to date, thanks to a combination of enhanced engineering and state-of-the-art technology that’s used to create each wheel. With flow formed technology, we maintain the overall integrity of each and every SV-F design while applying pressure to the wheel’s inner barrel to compress and stretch the aluminum to increase its tensile strength, resulting in lighter and stronger wheels!
