I invested in a new Favero Assioma dual sided pedal Power Meter (The first new PM that I have bought)

Today I went for my weekly club ride, using both the Favero and my Stages. I suspected for some time that the Stages was under reading, and the ride today confirmed it. Overall the Stages was 6.5% below the Assioma, I plotted both lines together and can see that the Stages is consistently lower. The spikes in power, when climbing for example are very similar, however, it is when riding at 200-300W that the differences are biggest

Does this mean the Stages is plain inaccurate, or that your legs are out of balance to that degree ?

My leg balance was 50:50, so not that

What's wrong with my Assioma thread eh?

I'm yet to compare my P2M & Assioma, but I suspect also that my P2M reads a bit low (it was way lower than it's predecessor). P2M is on my TT bike still, might do my last Sprint of the season using both and do a comparison.

My Sunday morning ride power is improving nicely though; yesterday I did a rolling 73km/732m at 30.7kph (road bike) and 230w NP (205 TSS). That's 0.92IF. My pedal smoothness always seems to be 20/20% and the Torque efficiency was 73/72% yesterday.

So many metrics!

Jorgan, appologies for not adding to Assioma Thread - I must have missed it. Can a Moderator combine them
