The Topeak Weatherproof RideCase with PowerPack allows cyclists to accept phone calls on tour while measuring and monitoring their athletic performance levels via a training app. Specifically designed for the Apple iPhone 5/5s, the weatherproof shield extends its usage time by up to 1.5 times, and provides full phone functionality and touchscreen access even in wet conditions. The package includes a fully angle-adjustable mount for the headset cap or for mounting it on the handlebar.
