I am seeing a pretty consistent difference between what my Rally Pedals are reporting (using them with TR PowerMatch on KICKER Bike) and what the KICKR Bike tells Zwift it’s actually doing. Thus far it’s around 5% on average but in many cases it’s a stable 9-10 watts throughout the ride regardless of power. So the KICKR Bike reports a pretty consistently higher power to Zwift, than my Rally Pedals are showing on Trainer Road & my Garmin Edge. I’m assuming it’s normal. I am trying to just figure how to make them “match” and just leave them on my bike all the time and use the KICKR reported power for training. I may be overthinking this. Right now I have 20 data sets entered into Excel.
The Kickr bike should be slightly below your pedals by 1 - 3% due to drive train losses. The Kickr being that much higher says one of them is not reading accurately.
Have you looked at the left / right balance from the pedals? Is it close? Or is there a big discrepancy?
Just chiming in, my Tacx neo2T has always been 5-10 watts lower than my rally pedals. Maybe one is inaccurate but as long as it’s consistent every ride, does it matter?
Your Tacx neo2T should read lower than your Rally pedals due to drive chain losses - estimates put that at 1 - 3% assuming a clean and well lubed chain / belt. So depending upon the the situation 5 - 10 watts lower is plausible, but seems high.
It seems like my L/R Balance is reasonable. My last two rides on the trainer were L/R 48/52% 49/51%.
I’d have assumed the KICKR Bike might be a little lower and not as low as a traditional trainer with bicycle drivetrain losses. I have a friend who thinks his KICKR Bike reports higher as well, it that’s anecdotal and he has not loaded any data into DC Analyzer. I am plugging multiple sets into a spreadsheet to look at overall power differences. I typically do not use the beginning and end of a ride since different devices tend to connect and disconnect at different times. Below are a couple of examples. Zwift Captures the KICKR Bike and my Garmin device captures the Rally XC 200 data.
I take it back, while I was looking at my spreadsheet and reviewing this thread, I realized I had not really focused on DCAnalyzer Left and Right data. As you noted, my Left and Right Power bracket the Garmin total power number with my Left being lower than my right. When added, they do add up to the Garmin total power. I’m still trying to determine why the pedal reported power would be consistently 5% or more lower than the KICKR reported power. I know it’s not a big deal, but I’ve see other quirky behavior with these pedals and am trying to decide if this is just normal or if it’s time to reach out to Garmin Support (again).
Does anybody have experience with replacing a pedal body of the 200 series? I discovered that my left pedal body is damaged and needs replacement, but I cannot really find the replacement parts.
I also thought about contacting Garmin, but their website is horrible and it seems impossible to contact them.
I also have the 200 series for the xc pedals and noticed a piece on my pedal body by the tension screw broke. Not sure how this happened as the pedals are on my CX bike and I can’t remember hitting anything of substance. Maybe when I clipped a small rock at a race back in October but it wasn’t a crazy impact. Pedal still works but I’ve been on the hunt.
I replaced two sets of bodies this year and it was really easy. Availability at the moment is poor and I expect it to only get worse with the new release.
Yup, pretty “simple” to change pedal bodies. They send everything needed besides the axle and battery. They look like new now! Definitely suggest doing so if you can acquire them.
