It's been proven on the road; now you can take your power training off road with the innovative PowerTap Disc Brake Hub System. 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.

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. No more wires to get in the way on a technical decent or tight wooded single track. It helps with clean up too; who wants to worry about wires when srubbing mud off a frame after an epic ride.

By zeroing in on your ride metrics the PowerTap SL 2.4 actually puts you more in-tune with your body. How much work does it really take to power over that boulder garden, and how many calories are you burning slogging through that momentum-sapping mud?

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 out of the way.

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.
