Why Train With Power
Stop guessing. Start pacing. A power meter is the most accurate measure of your effort on the bike. Having the right data lets you ride faster, go farther, and enjoy every ride.

“
The process to get these power meters installed was very easy, I just mailed in my current cranks and they installed the power meter, and mailed it back. My 4iiii has been extremely easy to use and accurate. The dual-sided power allows me to make sure I’m sitting even and pushing equal watts. Power is an essential way to measure my progress over time and have a metric to build off of.

I’ve always believed that data is only valuable if you know what to do with it. 4iiii power meters are trusted, accurate and built on an incredible heritage – and I’m excited to work with the team to help more riders get set up properly, understand the numbers, and use power to train with real purpose.
