Giant Halo Power Meter

Equipment
1

Recently upgrade to the Giant Propel Pro 1 which comes with the Power Halo. Couldn’t find any posts regarding this powermeter and so far have been less then impressed when comparing against Assioma pedals.

Preformed a static weight test on the pedals prior to the below. and calibrated both before each ride

Outdoor ride - Initially the Halo reads high however it then starts drifting down. By the end it was reading significantly lower

Thanks for sharing your experience, I’ve had 2 of these on my gravel bike as at the time of purchase there were no SRAM spider based PMs available at the shop., unfortunately they all stopped working at some point, one was bricked by a firmware upgrade and 1 just stopped working/charging for no apparent reason.
I am now getting said SRAM power meter as I’m feed up with Giant at this point. Luckily my shop is being good about this and I will just have to pay the difference.
