  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.

  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.

  “

  4iiii is extremely easy to use and accurate. The dual sided power meter allows me to make sure I’m sitting even and pushing equal watts. Power is a great way to measure progress over time and have a metric to build off of.

  The process to get these power meters installed was very easy as I just mailed in my current cranks and they installed the power meter.
