Garmin Edge 510 Bundle and OF Mount - $399.95

You've been happy with the Garmin 500, we get it -- it's small, has useful data, and quite simply, it works. So, you're probably desperate for a reason to upgrade to the Garmin Edge 510 Bundle and OF Mount. Well, how about three reasons -- a longer battery life, a touch screen interface, and the all new Live Tracking feature. Essentially, Garrmin designed this computer to be the Edge 810 in a smaller package. Sure, you don't have all of the functionality, but then again, you're also saving $200. Regardless, though, the Edge 510 Bundle delivers functionality in leaps and bounds over the venerable 500. Not only that, but it also includes all of the training accessories that you need to kick this race season off right. Starting at the screen, Garmin placed a focus on simplifying screen and metrics navigation. The initial start screen prompts you to select the CPU's functionality for your ride, either 'train' or 'race.' To avoid confusion, training mode is presented in Blue, whereas race mode is presented in Red. Additionally, this screen enables you to select the bike profile that you'll be riding -- mountain, road, cyclocross, or even unicycle if you're savvy. Once these selections have been made, you simply touch the ride button, and the screen moves to your race or training page. And of course, this page is customizable for every bike profile in your quiver. So, your ride page will only reflect the data that you deem pertinent to your ride or race. Even more impressive, and a jump away from the button navigation fumbling of the 500, the 510 allows you to simply swipe the touch-screen from page to page. Also, Garmin designed the screen to operate seamlessly with gloved hands in the cold, in the heat, or even in wet weather. And as long as we're on the subject of new features, you'll should be ecstatic to hear that the 510 is Bluetooth ready. - $399.95
