Simple wheel size setting with Tire Selection

Simple wheel size setting
with Tire Selection

In order to have accurate speed and distance, you have to tell the PURE 1 what size tires you have on your bike. The new TIRE SELECTION makes this easy. Simply select your tire size from the list of the most common sizes. For 100% accuracy, or if you can't find your tire size, you can still measure the circumference of your tire and manually enter this wheelsize.
