Now any crank can be turned into a world-class power meter capable of giving you the data you need to beat personal bests like never before. Designed with trademark durability, the PowerTap power chainrings provide exceptional value in enabling you to measure power using your favorite cranks without costly modifications. The PowerTap chainrings are a full-featured, crank-based power meter that features dual-sided measurement. The FSA-made, one-piece chainring design provides added stiffness for shifting no matter the terrain. Available 53/39, 52/36 and 50/36 chainring tooth options for 5 bolt, 110mm BCD cranks, the chainrings mount to existing hardware on the bike. Additionally, dual band ANT+ and Bluetooth SMART connectivity make the PowerTap power chainrings an obvious choice for riders looking for more features and better value.
