The OSPW System is seriously fast. Like, top-level pro fast. You’ll see it on the bikes of all the athletes at the Ironman World Championships—because it actually makes a difference. It improves your drivetrain efficiency, so you’re getting smoother, faster shifting without any extra effort. The oversized pulleys reduce friction, which means more power to the pedals and less energy wasted. If you're a serious racer looking for every advantage, this upgrade is for you.
