Garmin's got a lot of products showing up on its website we've never heard of, including two cycling computers in its Edge range -- the 510 and 810. Both have GPS / GLONASS-based tracking and do what pedallers want them to do: log distance, speed, gradient info, and other measurements from ANT+ sensors if you got 'em. You can now also connect them to your smartphone via Bluetooth so the Garmin Connect Mobile app can add some additional features, including live web tracking if you know anyone that wants to watch you two-wheeling around a 2D map. It'll use your phone's data to show weather info on the Edge's display, and share details of your ride to social networks. You can head to the source for in-depth details on both models, but the main differences are that the 810 has maps / on-screen navigation capabilities, a bigger touchscreen and slightly less battery life. You're going to have to be a pretty keen cyclist to wanna pick one of these up. The 510 costs $330 and the 810 costs $500, with the latter available for purchase on Garmin's website right now.
