Putting the H3 – a premium level trainer – into the mid-range price bracket. This is a good move by Saris. Could cause a few other pricing movements in the industry.

  1. Hi Shane. I recently purchased an H3 for my first smart trainer. I loved the way it felt, but the power reading was significantly lower than what my Stages Left Crank power meter was showing (22% lower average after doing a power comparison). I determined this must be a defective unit so I returned it and had the ship I bought it from send me a new one. Same issue on the new one. Now I wonder what may be causing this issue because I doubt I got 2 trainers with the exact same defect. All firmware is up to date on both units and calibrations have been performed. I noticed in your video the power comparison was pretty spot on. Any ideas/suggestions?
