bike bits - bike computer
Some riders are obsessed by their little screens: how far, how fast, how long. Further and faster than yesterday, or someone else. Gotta make time.
They do indeed have their downsides.
On the other hand out in the relatively featureless, even ambiguous, landscape a bike computer helps work out your location and useful things like how far is it to the next waterhole or campsite.
Yup, an essential piece of kit. The ideal model would have a switch to turn the screen off most of the time.
And as long as they don’t take over your journey.
