Vector 3 Power Imbalance

I am riding on a trainer right now

I have a Garmin Forerunner 945 as my main recording tool (I do not have a head unit and trying to avoid buying one until next spring when I can get outdoors again)

I manage my Vector 3 (just go them a week ago) from my iPhone and currently running firmware version 3.80

I have tried the standard rotate the pedals till they wake up and leave them in the horizontal position so they can auto offset (I have this turned on).  I also leave them in this position when I'm done with my ride.

I have done two rides (45 min, 1 hour) at a pace to keep my heart rate low.  Since i'm a novice this means my power is ~125W and my speed between 18-20MPH.

Problem is my power balance is very Imbalanced.  My concern is I don't know if this is "real" or something is off with the pedals.    If it is real, I can at least work with somebody to correct this.  Personally I did not buy the power meters to measure my power.  I got them to give me feedback on my technique to make sure i'm not developing less than ideal habits.  

So...is there anything I can do to begin to figure out if the meters are right or is it me?

  • I own all three versions of Vector pedals.  I am ancient, but still riding a lot.  I injured my left knee years ago playing basketball, and finally had to have a knee replacement in March of 2017.  I did my physical therapy, and I still do some leg exercises at the gym.  I feel that my legs are close to equal in strength.

    My Vector1 pedals tend to measure my balance at about 48% - 52%.  Vector2 is usually 46% - 54%, and Vector3 is usually 50% - 50%.  The three units also tend to show different power levels, with Vector3 generally highest, but the difference isn't great, 10% or less.

    The Vector3 pedals issued a message a week or so ago that the right pedal had come unpaired to the left.  I saw power fall to roughly half what I usually produce, but after awhile, I was getting figures in my ballpark.  I think the left took over and acting like a 3S unit.  Today, I noticed that balance and other info was missing.  I paired the right pedal again (which is a pain - I cannot read the tiny etched number without a magnifying glass, so I wrote it on the outside of the pedal box for future reference).  I'll see if everything is OK tomorrow.

    The fact you are seeing left and right figures indicates your pedals are paired.

    I think I'd go for a "real" ride - at your normal levels of effort, for at least 30 minutes, and see what results you get.
