I've been riding a '91 Diamondback cenrurion for a while now that was given to me. Didn't really see the point of a computer, as I just ride for fun and the bike is in crappy condition.
Now that I'm really getting into cycling and plan on getting a new bike, I'm going all out.
A comp with cadence is definitely on the list. Hopefully the additional info and depth that the comp provides will enable me to better myself. I also find all the info fascinating and would like to participate with Strava.
