It's time to leave the guesswork up to the competition. When you train with PowerTap, you're training with the power of precision. No other piece of equipment gives you calculated performance measurements like the CycleOps PowerTap SL 2.4.

The customizable display has unlimited interval capacity and can simultaneously show power, heart rate and cadence—or let you choose which metrics are displayed.

The Shimano or Campagnolo compatible hub is light enough (416 grams) to train and race with so you can collect ride feedback 100% of the time.

Adaptable and easy to use, you'll see progress like never before and make massive gains in your training and racing.

As the first wireless and only power meter on the market, the PowerTap SL 2.4 uses coded digital technology for reliable, clean transmission of heart rate and ride data from hub to handlebar. This technology has allowed us to eliminate crosstalk and data dropout even when riding in a group so you know exactly how you're performing with every pedal stroke.

By zeroing in on your ride metrics the PowerTap SL 2.4 actually puts you more in-tune with your body. Thanks to perceived exertion, you'll always know when you feel great or not–so–great, but now you can attach real numbers to those feelings.

By understanding where you need to be for a great ride every time, your training actually becomes easier and more focused. And because cadence is measured by torque—not with a separate sensor—the computer is 100% wireless, easy to install and can be moved from bike to bike for collecting data even when you train on multiple bikes.

Training to be the best is hard work, but you can make it easier by training smart. With continuous data recording for current, average and max power and speed, current and average heart rate and cadence, total energy expenditure, ride distance and ride time, there will be no questions unanswered at the end of your ride. Except by the people you beat.

Once you're off the bike, simply download the data via USB cable to your computer and use the included PowerAgent software to analyze your ride metrics, investigate interval stats and track your improvements over time.

With a +/- 1.5% accurate measure of performance, PowerTap SL 2.4 is your secret weapon in making quantifiable progress in your training.
