The Kura is a "Direct Drive" "Fluid" trainer, the resistance changes concerning the speed variation, and it has included the power meter.
This is a graph of powers created by the Kura in relation to the speed of pedaling: Kura power graph
A specific explanation of how a fluid trainer works can be found at this link ( Fluid trainer )
The internal trainer board transmits wirelessly using ANT + and/or Bluetooth Smart protocols the values of:
- Measured speed
- Calculated cadence
- Measured power
Any app/software/device ( such as a cycle-computer ) which uses ANT+ and/or Bluetooth Smart protocols may receive the data listed above without altering the resistance.

Note: The circumference value in the external device must be set as: wheel circumference / 3.43
Example: wheel circumference 2095mm, set in external device 2095 / 3.43 = 611 mm
