This GPS receiver mounts to a standard 1" bicycle handlebar. It also includes an integral antenna and a speedometer on an easy to read LCD. The GPS has 16 channels and can save up to 110 waypoints and 20 trips, and provides latitude, longitude, and altitude; the altitude profile setting allows you to plot the cross-section of a mountain you climbed. The speedometer displays the time, current, maximum, and average speeds, speed comparison with your average speed, and has a trip odometer; a compass ring provides your bearing while riding. The GPS comes in a splashproof casing that is also shatter-resistant.
