I’m excited about the someday-to-be-released Metrigear pedal based power meter system, but I got tired of waiting and decided that it was time to add power to my weight weenie machine. Here are a few photos of the system weight including everything except for the head unit. The lightest head unit I could find was the Bontrager Node 2, but I like the Garmin EDGE 500 better, so that’s what I’ve been using. The Node is maybe 20 grams lighter than the Garmin, but the display on the Node shows your speed in huge numbers and the power in really small numbers, and you can’t configure the display to do otherwise. I don’t really care how fast I’m going, but I really care about the wattage I’m producing. The Bontrager Node also doesn’t store the power data, rather it just displays it. This is fine for pacing yourself while racing, but it’s not much good if you want to analyze the numbers later. The Garmin, on the other hand, lets you configure the display so that your power is most prominent, and I love it. I have mine configured to show power (largest), heart rate, cadence and distance.
The 622 gram scale photo includes the cranks, the Quarq, the BB cups with ceramic bearings, and even the BB magnet attachment.
