Planning to buy a new pair of Assioma power pedals

Off the back of this thread I just picked up dual sided mtb versions.

As there is a Sigma Sports shop not far away; i was able to order for next day pickup.

The first thing I did was put them on charge using supplied cable. Whilst that was going on; I removed my old broken left power meter crank and put the original crank back on.

Crank on. Installed the Faverro app on my phone. Select new pedals and it will walk you through setting them up. Seems first thing you need to do is put them on charge, as they are put into what is called travel mode at factory. So did that already!

Then removed right pedal from bike. Some grease on Faverro pedal threads. Then screw in pedals by hand. Check the right pedal nub with led clears chain by at least 4mm with chain in big ring. Plus also clears chain stay by same amount. Use one or two of supplied washers if not. Did not need washers, so straight to snugging up pedals with pedal wrench. Nothing stupid, just nice and snug.

Then in Faverro app search for your pedals. Then fill in form in app and submit to activate them. This also starts warranty period.

After activated, pair with your bike GPS (under sensors on Garmin). On paired go into sensor settings in your GPS and set the crank length. Set cranks vertical and do the calibration / zero offset option.

Add power data fields on your GPS. Go for a pedal. After about 20m or so the fields will start showing values. The first pedal strokes the pedals do some further internal calibration.

Having bought dual sided I was amused to see.

Though there are lots of other useful metrics such as how much of the pedal stroke I am applying positive power through for each leg. Plus peak power phase etc.

Plus only a recovery ride today. Will see how balanced it is for my VO2 max session tomorrow.

Nice to have power data back.

Oh and after my ride whilst looking around the Faverro app. It had a firmware update to apply. That update is the one that takes them from 60 to 160 hours between charging. On the mtb pedals it moved to version 7.10 or similar. The app also gives you a bar showing current charge state of each pedal. Mine are at about 75-80% charge.

On my VO2 max today I see a difference between left and right. Means my single sided would have been underestimating my power output. Money not wasted 😁

Not surprised as mountaineering accident damaged left leg a little over 20 years ago, and would not expect them to be same.

i had a single sided power meter for ages (4iiii) and I never truly trusted its figures. Once I had a set of Assioma's found out my L/R balance is weighted towards right side, but it varies a fair bit from ride to ride (worst I've ever seen is 40/60 but its usually around 46/54). I have no obvious reason why this is the case as no accident or injury to explain, and whatsmore, I'm left handed and left footed when I played football when younger.

Dual sided Assioma's are the gold standard and what I use on my best bike but I have an AliExpress £70 Thinkrider spider power meter on another bike and that gives me far more trustworthy figures than the 4iii ever did.

This is normal. Anywhere above 45/55 is to be expected. Someone achieving 50/50 over a sustained period is extremely rare.

I have found since having a power meter I’m burning less calories. When my Wahoo was basing my calorie expenditure on my H/R weight and age rather than my power, weight and age. I was burning nearly twice as many calories.
I might have sack off this power thing.🤣🤣🤣
