Why Train With Power
Training with power gives you precise, instant, and objective data that removes the guesswork from pacing and accurately tracks your true fitness progress over time. Watts don’t lie, and won’t fluctuate due to fatigue, stress, or dietary factors - they’re the consistent metric that the world’s best cyclists, and now you, can rely on.

With climbs lasting between 20 minutes to over an hour, my 4iiii power meter was an essential tool for pacing the 7+ hour day. I love the art of modulating my own effort while competing and pushing into new realms of possibility.

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.

After identifying some power imbalances with my dual-sided pm last year, and addressing it in the gym, the stat I was most proud of was the near-perfect LR balance I achieved (49.9%/50.1%)

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.
