I’m looking for a bicycle computer (speedometer and mileage, primarily, but other measurements are always nice too) that’ll allow me to download data to a PC (or a smartphone!), preferably but not necessarily in an open format.
I know there are expensive Garmin units with built-in GPS and color screens and wireless data transfers and all that, but I don’t need of that… just a basic computer with exportable data (that’s hopefully a lot less expensive).
Does such a thing exist?
