Why do so many professional cyclists and endurance athletes train and race with the PowerTap SL? Because they know that training hard is only part of the winning equation. The other part is understanding how speed, cadence, heart rate and power are related and how to balance all four for the ultimate pay-off on race day.

With PowerTap SL we don't change the principles of training, we simply give you the tools to understand how to ride your best. By identifying the exact speed, power, heart rate and cadence that you're at when you feel your best, you can strive toward getting to that point on every ride. After all, what good is power if you don't know how to use it?

The PowerTap SL is a wired model.
