From $500, Amazon.com

The draw: Least expensive dual left/right power meter

While WatTeam had a bit of a false start in 2015/2016 when the company had to recall its products due to accuracy issues, WatTeam is back at it in 2017 with a much-improved unit—one that’s largely matching accuracy of others in the market. Most notable about WatTeam: It shifts the “factory” from its HQ to your garage, where you install the unit onto your existing crank arms. (Most other companies pre-install sensors onto crank arms.) Doing it yourself saves a bundle of money, though you’ll probably spend an hour or two getting it installed (one time). Still, for many, that’s worth a $500-plus savings.
