I have to buy a power meter to train for next years season. My choices are power tap pro and stage one. I would like to get the stage one for its light weight and my ability to change out wheels and still have power, but the release date is January 1 and I think thats a little late for a power training plan. Plus I am a little iffy about the fact that it only measures left power. I like the power tap because I can change it between bikes and its proven technology. Any suggestions?
