PowerTap Joule GPS Computer

When we set out to improve the Joule – the world's first cycling computer designed for cyclists who train with power – we realized that all the data in the world isn't going to help you achieve your goals if it isn't intuitive and easy to use.

Through years of working with cyclists and triathletes of all levels, we understand how to turn training and racing data into meaningful information.

When we designed the Joule, we spent hundreds of hours with cyclists, triathletes, coaches, and exercise physiologists, and realized everyone wants answers to four key questions:

What am I doing?

What have I done?

Am I getting better?

What should I do to improve?

Joule helps you answer these questions. We realize your training changes. You change. Training with Joule means you'll always know where you are, where you have been and where you need to go. Every ride with Joule can be as targeted and specific as you need it, giving you the precision and effectiveness necessary to perform at all times.

Put your training on the map with Joule GPS. With compass, route mapping, and waypoints, you'll always know where you're going and where you've gone, literally!
