Hi there TR folks,
I’m hoping you might be able to shed some light on some increasingly frustrating issues I’m having with my Wahoo Kickr (2016 model) and Garmin Vector 2 pedals.
The main issue is this: the Kickr registers roughly 12% higher power than my Garmin Vector pedals. That’s a huge $%^&ing difference. Unfortunately, it’s not even a constant difference. At times (and usually at lower power output), the difference drops as low as 6-7%. In others, it can be as high as 15%.
I’ve done everything you could possibly think of in terms of troubleshooting: recalibration, changing batteries, spindowns, etc. I’m tempted to kick the damn things as it may yield a better result! Anyway, I know you can power match on TR which is great but I’m still trying to figure out how on Earth there can be such a staggering difference between the two power meters.
I like to use ERG mode (who doesn’t it!?) which means it makes sense to set the Kickr as my default power source. However–and this is my BIG concern–when it comes to riding outside, be in for a training ride or in a race, my FTP/power zones won’t be applicable with the Garmin Vector pedals (i.e. I simply can’t set my zones to say 12% lower as there is simply way too much fluctuation).
I would really appreciate if anyone has encountered similar issues with their equipment and how to overcome these quite frankly pain-in-the-ass problems. Needless to say that I’ve contacted both Garmin and Wahoo about this issue and both parties have been utterly useless at helping me sort this out. So I’m hoping one of you fine folk might be able to help!
