Powertap C1 Chainrings Wattmåler

The Powertap C1 chain rings allow you to install your power meter on virtually any 5-armed crankset. The great thing about a power meter, is that it allows you to go even further when it comes to collecting data. You can train more effectively, as power is a more constant method of measuring than for instance heart rate, which is susceptible to stress, heat, cold, rain, or even just how you feel that day. The data is transferred using ANT+ or Bluetooth Smart technology, making the chainrings compatible with virtually any cycling computer. Firmware updates can also be carried out wireless via an ANT+ Dongle.
