Power comparison with Vector 3 Pedals

Hi,

I got my 2T today and did my first ride using TrainerRoad. I used the 2T as the power source in Erg mode connected to TrainerRoad, with my Vector 3 pedals connected to my Edge 1030. There was a significant defference between the power readings of the two devices of between 15 and 20 watts; the Neo reading approx 245 and the Vectors closer to 260. A chart is attached showing hte two rides overlaid on one another.

Is there a problem, or is this normal? I don't know how the different readings are taken, but assume that they should be broadly similar across the range - the variation seems to great to be accounted for by devices at opposite ends of their tolderance ranges to me. Grateful for your thoughts?

Any advice would be gratefully accepted.

  • Yep, same here - Neo 2T vs Assioma Favero Duo... 4-5% off (Favero reads higher). I thought it was related to the fact that Favero (just like Vector) measures at the pedal and there is no efficiency loss through the drive train, where Neo 2T measures.
