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?

Weighing in at only 416 grams, PowerTap SL's Shimano or Campagnolo compatible hub can be used with virtually any wheel. And because it's so lightweight, it's perfect for racing as well as training, so you're constantly gathering performance data.

Store up to 15 hours of data and unlimited intervals, with the ability to view past intervals while you're riding. And with the customizable display you'll never be more than a glance away from knowing your ride metrics. Simultaneously view power, heart rate and cadence—or mix it up further by viewing speed, distance or elapsed time. Compare heart rate to power output at any time or use the heart rate monitor off the bike for other endurance sports. The choice is yours. And so is the power to perform.

By accurately recording the most sought after data 100% of the time, with +/- 1.5% accurate measure of performance, PowerTap SL and the included PowerAgent software allow you to analyze every detail of your ride. Track improvements, watch your power increase and get the most out of your training time by downloading your ride data via a simple USB connection to your computer.

Zero-in on any segment of your ride and customize your workouts based on your goals. With PowerTap SL and PowerAgent software it's easy to make strategic changes to your training so you reap the most substantial benefits.
