I have a Red Garmin Edge 500 GPS bike computer for sale. I’m asking only £120 for it. I have had it for less than a year and it’s as new, there isn’t a mark on it. It comes with the box all the manuals, USB power adapter (UK, Euro and US adapters) cable and mount as well.
Very easy to use and customisable. These units change hands for around £150 on ebay.
If you are interested please message me on this thread or come and see me at turbo training.
