Dear forum members,

I am new to this forum, that why I am asking for your understanding. (at the beginning I tried to find a similar topic / discussion but I can't found nothing, that why I ask you for support)

I am the new user of the "KURA" Trainer Elite in combination with the Polar V800 sports computer.

After several trainings, I noticed that the speed and the distance traveled is wrong (many times higher than it actually should be).

In the computer settings: Polar sets up:

- crank length: (172.5)

- circumference wheel (2150) - Same like in 28'' - bike has)

it seems logical that the value of the circumference of the wheel should be different - after the bike is put in the KURA Trainer - nevertheless I'm not able to set lower value in my POLAR V800 Computer: like 1000.

Dear members have you found similar problems - how can I solve this problem?

Any ideas for support?

Hi

You have to insert in your Polar a circumference value that also consider the internal ratio of the trainer.

In your case, you have to set a circumference equal to your wheel circumference divided by 3.43.

So, for example, if your wheel measure 2100mm, on the Polar you have to set a circumference of 612mm.

Not all the Polar (or the Garmin) allow to insert a so low circumference value unfortunately.

Check with the manufacturer if it is possible for your model.
