Hmmm.. yes providing you basically just want a speedo that will track your rides for Strava/GC. If you want to regularly use courses, use a HRM, use the 'map' like a compass as a rough guide, or like to be able to stop mid-ride and switch the unit off for a while to resume later - no.
Aldi doing the edge 25 this week. Anyone use one for training? Are they worth it for 80 pounds?
