Congrats to Garmin for having their brand associated with ALL bike computers much like Coke is to soda.
Let's face it, when you are training, you are not going to float from screen to screen to look at a ton of data while you ride. So, we try to get up one single screen with only the data you need to complete the training session on it. This can vary a little depending on the goal of the workout, but less is more in our opinion.
Some computers will have more or less options for data fields but the ones you really want to look at during a session are universal.
