TR power smoothing


#1

Apologies if this is covered elsewhere (I tried to search for it), but is there any reason to change the default power smoothing setting in the TR app of 5 secs? Should it change when using a powermeter and powermatch for any reason?

Smoothing only affects your display of power, nothing else. 5 seconds is a good balance, but depending where on the transmission you are measuring power then you might change it:

  1. Wheel-on trainer (I.e. Road Machine with a speed sensor), try 3s
  2. Wheel off trainer (Direto etc), try 5s
  3. Crank Based (Quarq et al), 5-7s
  4. Pedals (Assioma etc), 7-10s

In the end its personal preference; I used 3s on my Road Machine and found that when I swapped to the Direto I was always chasing the number so dialled it back to 5 seconds and am much happier.

I have a wheel-on trainer & a crank PM.
I’ve set TR screen to 3s & headunit to 5s. Seems to give me best of both worlds, using 5s during longer intervals and when I get tired (easier to keep smoother power with a smoother number display); using 3s for shorter intervals, higher power intervals, and also when I tire (easier to bump up a 3s reading than a 5s reading).

Trial & error to find what works best for you.

Thanks Ian. That’s exactly what I was after. Have just purchased the Assiomas so will look to lengthen the smoothing a bit from default 5s
