I've been thinking about bike computers. Over the years my bikes have evolved, gaining many useful bits such as fenders, front racks, and lights. Like many of you I've gone from riding, mostly, racing style bikes to riding a randonneuse and a city bike.One thing my bikes have been losing is computers. As the batteries died the computers were removed rather than fitted with a new battery. It probably has to do with age, but I no longer care much about how fast I am going or exactly how far I have ridden. I've lost my log book too.Now I'm not totally against cycle computers. They are OK for navigation. I still have one on my go-fast bike to make it easier to follow cue sheets on group rides. But, come to think of it, it's battery is dead too. Maybe even the navigation thing is overstated. When we went touring in France a few years ago Annette and I managed to find our way from remote place to even more remote place for a week with nothing more than a map, no bike computer or GPS. If all else fails, we ask directions. So, do you use a bike computer?
