MTB measuring problems. Why is measurement not accurate?
Posted: Sat Aug 10, 2019 6:19 am
I can not make a setting on PP who giving realistic datas about power on my MTB. I have power meter on my TAX trainer and also have direct power meter on my road bike this two has very similar datas about my FTP etc… I also comparate before last two calibration O&B ride Iin attachment) power with my friend, when we rode together one day , he has direct Garmin two pedal PM, the same kilogram and we had big different in measuring. Approximately 15-20% my PowerPod shower less than this. If I compare with Strava again it is more less.
I have setting PP according the recommendation for MTB CdA=0.49 , Crr=0.0086 , total weight is 92kg. After that I did calibration ride few times and everything was very similar not realistic results .
Please find attachment in this and next message
First O&B ride is only to 50% and back, and after that I have normal ride.
Second O&B ride I did on the same ride because I didn't was satis-fate but this was from 0-50 and back 50-100, after that when device started measuring i did one more time same track like O&B because comparattion , for you.
Las three files is my normal ride after second calibration, maybe this can help you to find where is the problem.
I point out that the PP is properly mounted on the original carrier (holder) and the cables do not interfere.
Please help me to setup this device correct , this data now make confusion on my Garmin devices about my fitness…..
I tied PP on my road bike earlier and the results was very realistic. My wishes is use this device for all of my bikes
