On MTB or road tours, you obviously want to enjoy your surroundings. But you also want to track how fast you're going, how many kilometres you've notched up, your heart rate and your cadence. For this kind of data, we turn to bike computers. Unsurprisingly, the more features a bike computer offers, the more expensive it is. For multi-day bike tours, bike computers with navigation are a great choice. These often even offer several routes to your destination - allowing you to concentrate entirely on cycling.
