Eagerly awaiting mine, are they easy to setup? Has geoid their own app or is it magene

magene app i think

it definitely pairs with the Magene app. Haven't seen any firmware update so not sure if that is how we will receive it

What interface does this use guys? Got mine and really like it, just wondering if there's any Chinese carbon cranks with the same interface that can be used?

proprietary, as has already been said in the thread

sorry didnt see it, thought it was an easton interface? are all SENICX PR3 cranksets using the same proprietary interface? seems inefficient

No, it's a custom PR3 crankset that uses the proprietary interface. It's basically Easton with a notch missing (or at least that's my understanding). Standard PR3 cranks use the old SRAM 3-bolt standard.

Strange design decision, wonder what the reasoning was.

Considering it's a missing notch, wouldn't it be compatbile with the Easton interface?

NO, it's not like aston at all. The outline of the easton intefrace curves smoothly all the way around. The peaks and valleys on geoid all have flat faces. Please, I'm begging everyone, take a minute and use your eyes before posting bullshit, you could cost someone good money if nobody happens to correct you.

What is similar is that the spacing on both is for 16 pairs of valleys and peaks, so you could painstakingly file every notch on the geoid and you might end up with a loose fit.

It's way different from Easton... Not just a missing notch...

Thanks for the correction - I wasn't intending to mean that it was compatible with Easton (or that it could be), more that it was a similar size, spacing and design but definitely not cross-compatible.

what's the general consensus on power accuracy on this?
manufacturer claims 1.5%

Does anyone know if you can replace the left crank arm with a Shimano arm (105 or Ultegra) to save weight?
The Q-factor is slightly different —146 mm Shimano vs. 149 mm Geoid—but this could be compensated for with a pedal spacer.

The only question is whether the interface for the crank arm is identical.

Given the Magene PES P505 is also 1.5%, it should be the same.

I encountered a bug after installation. I performed a calibration using my Garmin watch, but although I purchased the 165 mm version, Garmin displays the sensor length as 172.5 mm in its details. After my first ride, the recorded data appears to be doubled. I’ve contacted the Geoid Support Centre and will see how they respond.
