Cycleops question

[masking_agent]

so I have both the supermagneto pro (magnetic) and the jet fluid pro (fluid) indoor trainers.

They are set up exactly the same within millimeters of difference only.

I normally ride on the jet fluid pro fro the past few months.

So when I picked up the supermagneto pro, I noticed a huge discrepancy in the numbers on my garmin as my speed is higher and it appears I'm riding faster ? along with my overall average speed is higher. If i put the setting to "mountain" then it resembles more to the jet fluid pro speeds which is 3-7kmh slower.

There is still too much slush on the ground so I can't go outside yet. I want to know, which one is more accurate ? Any ideas ?

I've had 2 generations of cyclops fluid trainers with a noticeable difference in resistance. The older one required lower gears to maintain the same resistance as the newer one. My speed sensor told me the difference was something like 15 mph average compared to 19 mph, the latter was more realistic.

I guess all I'm saying is that they're calibrated differently, but what does it really matter, you're still going 0 mph on a trainer.
