LEZYNE ENHANCED SUPER GPS £130

It’s not the slimmest design, but its compact case packs in heaps of features. With up to five pages showing four data fields, including turnby-turn navigation, Strava Live Segments, ANT+ power meter and Bluetooth Smart connectivity, we can forgive the button-only operation. It also boasts a battery life of around 24 hours and the ability to display incoming phone calls and text messages when paired with the free app.
