I am in the process of setting up my trainer. It is not a smart trainer so no electronics. I have been looking all over the web to be able to track my training. I have a Garmin watch that works good for road riding but does not help much on the trainer. I am looking at speed and cadence sensors. The Wahoo stuff looks good but I am thinking about staying with Garmin for my setup. I am also looking at the Wahoo "free" version app. I am not sure if I should use a laptop or a led tv for viewing. My laptop is not setup for bluetooth and I don;t have a smart tv.
