Strava; powermeters; heart-rate monitors; cadence sensors; GPS; electronic shifting.....
I just don't get it. All I want to do is ride my bike, and enjoy the ride; get some exercise; and sometimes I feel like I'm doing too much because I keep track of my mileage and speed on a $13 bike computer.....
I don't even want to think about all that other stuff!
Try it some time (the simple old-fashioned way)- it'll seem like a totally different sport.
