SO GOOD This feature-laden GPS unit uses GLONASS satellites to improve signal reliability. You can upload your ride to Garmin Connect, which is easily linked to your Strava account.
SO GOOD If you’re a technophobe or a weight weenie this could be the GPS unit for you. It weighs just 36g including the mount and set-up faff is minimal.
