I have an elite Kura and as of today no complains. However, I recently acquired the Assioma Duo, the problem is that I see that there is a watts difference (about 10 or 15 difference, indicating the Assioma more) between the Assioma Duo and the trainer Elite Kura.
I have talked with customer support both with Favero Assioma Duo and Elite. And Elite Kura’s customer service responded as follows:
Please take note of:
Kura and your bike power sensor measure the power in two different points
In particular your bike power sensor measure also the frictions on pedal and crank and instead those frictions are not measured from the trainer (because the power sensor is placed in a different position), then also you need to consider that the bike chain give some power dispersion so in the wheel the power is reduced a bit respect the power read on the pedals
A difference of 15-20 Watts so is the result of all this aspects and is completely normal
You also need to consider that the maximum error between the two measure is given by the accuracy of the power sensor:
Direto power sensor has an accuracy of +/-2%, if your bike power sensor (just for example) has the same accuracy it means that the difference on the read between the two sensor could be up to 4% (from -2% of one sensor to +2% of the other)
What you guys think? should I worry or just take into account always the Assioma Duo in order to be able see the same range of watts both in workouts outside and inside.
Thank you in advance,
