I have recently got brand new PowerTap P2 pedals as a replacement for my faulty P1 pedals which got me really excited but have had the following issue lately:-
Pedal firmware are both up to date.The crank length is set correctly from the SRAM AXS App and I do the Torque Zero offset correctly.When on ZWIFT I can only choose one side to connect to. When the connectivity menu is open where I sync my sensors when I choose which device to work on in terms of power I can see both the pedals power data and if they are added up together they give out the same power coming out of my KickR smart trainer (Wahoo). Which means that I am getting the correct data now but Im only reading the power from one side and not the added dual sided power.My Wahoo Elemnt bike computer connects to the sensors via Ant+ and I have realized that I am going through the same issue here. Data from one side only. If I compare my ride the other day on the new PowerTapP2 pedals vs my old data when I had my P1’s which we replaced I can see the data for both sides and the left rite balance etc… which Is not seen on my ride on the P2’s.
So the problems is not with the pedals calculating power/calibration/firmware/crank length and it is not with the connectivity whether it was Ant+ or Bluetooth Smart broadcasting signals to whatever device whether it was my Wahoo computer (Ant+ connection here) or ZWIFT (bluetooth connection here) on an iPadPro.
The problem is I am only managing to connect to one pedal of my choice (either left or rite) and hence I am only getting about half the power I am putting into the pedals (or to be more specific one sided power data but I am assuming both legs are producing near 50:50) and not the combined power data.
If you have any idea on how this issue is resolved please do let me know as I am trying to read over random triathlon forums and reviews in order to find out how to figure this one out.
I have seen a similar issue from the DC Rainmaker review and I quote in blue:- https://www.dcrainmaker.com/2019/03/powertap-pedals-review.html
As such, you have to choose only one of them. Typically the way companies handle this is that when an app connects to a single side (left or right), it still gives the proper total power (i.e. 300w). However, that’s not what happened here. Instead, Zwift only showed half my power (i.e. 150w). That’s less than ideal, obviously. In talking to PowerTap about this, this is a limitation of their design – and in order to get proper total power (well, a single leg doubled) you need to remove the battery in the other pedal. So that’s a pretty big Debbie-downer compared to Garmin, SRM, and Favero – which all have proper modes to handle this via dual-sided pedal design over Bluetooth Smart.
Is the solution to use one sided pedal then? I don’t think that’s a smart solution but any opinions would be much appreciated please.
