This makes sense, and I was thinking that it might be good for me in general. At my last riding/practice session I was having major problems with my pedal stroke which may have had to do with spinning too fast in an incorrect gear at too low of a speed. It sounds like the cadence monitor would be a good overall training tool.
I am certainly good at over-thinking things, that is just how I am and am trying to avoid that trap. I will also check with my trainer before deciding which computer to get. There is a rather large price difference between the computers with and without cadence...so I need to decide what makes more sense for me right now.
