With cleats on the tops of your shoes, you can do opposite pressure pedal rotations, which can help balance out the musculature of the legs. The double-sided pedals should help measure just how much under-side riding is needed to counteract the effect of normal top-side riding.

Do they read negative when youâre on a fixie going downhill?
Has anyone put power pedals on a retrodirect?

I know someone that used to have one and I might meet (edit: distanced) with him this week. Iâll ask if he still has it
You mean vertical cranks, right? Took me a second to work out. I would guess bouncing on vertical cranks does give a power reading.

SRM track cranks actually have twice as many strain gauges to subtract out the power coming from the drivetrain. I would suspect theyâre doing a differential/error calculation between the two sides of the Speedplay.
Also, Iâm making popcorn for the internet engineersâ reviews about accuracy.

All the above is a joke. There arenât âtwo sidesâ. The strain gauges will be 360d around the pedal spindle.
put some lateral strain gauges in to finally quantify planing

I presume, based on the photos, that the Speedplay will be similar to the Favero pedals in terms of construction. It makes the most sense and it explains the hex-key only spindles. The Assioma looks like this:
The strain gauges are in the pod on the spindle and measure force relative to the spindle regardless of the orientation of the pedal. Further, thereâs no âupâ or âdownâ strain gauges. The pedal is installed and will seat on the crank at whatever orientation it lands in. One presumes the pedal itself figures out which way is down based on gravity.
From there, the force vectors in any direction are measured as well as momentum from this, the pedals can derive power and cadence using complicated math which is their special sauce. The âbouncing up and downâ phenomena has to be filtered out, again, thatâs the special sauce.
Iâm assuming the Speedplay works the same. I could be entirely wrong, but⌠If they come up with a power meter thatâs as reliable, easy to use, and priced competitively to the Assioma, they will have a successful product on their hands.
If none of that makes any sense at all, then I offer my direct observation that when I miss clipping into my pedals and end up pedaling against the bottom of the pedal, they have no problems measuring my power output.
Hope to hell they have rgb

But will they work with four sided pedals? Wonât two sides be orthogonal?

Serious question: for the pedal power meters wonât your weight distribution on the pedal change the length of the lever arm for the sensor and affect the readings?
