Cycle Computer CM 4.21

This new wireless cycle computer features not only with its modern and innovative look, but also with its PC configuration. This means that all accumulated data can be read-out from the device. The CM 4.21 is the perfect attender for the ambitious cyclist on ample tours. Due to the TwoInOne system it is possible to use two different wheel circumferences. The CM 4.21 therefore can be used for two bikes and be upgraded with optional cadence and heart rate functions.
