In power sensor comparisons, the blog with the most measurements is that
of DC Rainmaker.
He tests almost all new products and compares them
with existing references. So, to test a new
power meter crankset, for example, he will also record data with a PowerTap G3 as well as P1 pedals.
Power curves overlaid by DC Rainmaker: DZers P1 vs G3
There’s nothing like multiplying measurements to get The latest tests an idea of a sensor’s accuracy. The author analyzes the behavior of
sensors on home trainers as well as on road rides. The analysis remains
global and does not go into detail. He now offers some zooms
on certain accelerations, superimposed phone number library curves and PPR of the ride. We can go further in the analysis because he
now makes the files of his comparisons available. Thus I
was able to analyze his rides for 3 tested sensors: Vectors 3,
Assioma pedals, Quarq DZERO.
I took random durations and analyzed with WKO4 the
watts delivered by each sensor at the same time.

I chose the Powertap G3 as
a reference since it is present in each how to use lossy compression in wordpress test. Of course, we know The latest tests the
limitations of the G3 in a comparison. The measurement accuracy of the hub itself is good, but wear, lubrication, and the
position of the chain on the cassette can cause friction losses,
therefore variations in measurements from one comparison to another!
Assioma VS PT G3 vs P2MAXNG pedals
Last comparison with the QuarQ DZERO test , he used
his G3 and the P1 pedals. The results seem to show a certain
generosity in the measurement like the P1 also compared to the G3. This may
seem logical if we think back to the possible losses due to friction at the hub. Dc
Rainmaker also seems to specify this in his betting email list comments where the cleanliness and
condition of his chain left something to be desired that day.
