Product description
Height, incline, decline, total height climbed - with the VDO M4 WR the aspiring mountain cyclist or puncheur has all relevant data at a glance. Whether you're gaining altitude in the hilly mountain ranges or traversing seemingly endless mountain passes, the M4 WR collects valuable information and conveys that in a clear and easy to read way. Calibration is done by sea level pressure or altitude above sea level. Aside from the comprehensive altitude functions, a cycle computer wouldn't be complete without the other basic functions. Distance, speed and time are tracked and a clock indicates how long until you need to be home for dinner.
The M4 WR can be used with an optional second bike kit on two bicycles, there is a separate save file for each bike (kit not included in delivery). A battery level alert lets you know in good time before the next change is required. L'Alpe d'Huez, Mont Ventoux or the Stelvio Pass - with the M4 WR you're ready to take on the mountains.
