PP V1 - too low power in TT bike

Post by kdx200 »

Hi John / team,

ive just started the triathlon season so the TT bike is back. The PP recognized the profile and started to use it...(i use the TT combo rack purchased to you)
My power must be (or should) the same or near (ive used the MTB every day in the offseason to train a lot) the same and is not.
In some places i could feel the power (my legs near burning and +35kmh) with a little cross wind and the power shows for example 90w or even 130w... i know that is wrong... then when the wind is headwind also the power is underrated... for example 200w with a great mid-effort .
Please, take a look
thanks for your help

Looks like your wind calibration is low...I used the "Analyze/check calibration" feature to correct it.

Your watts increase to about 158 average, and there are places where watts exceed 200W.

Your wind scaling number is quite high; please post images showing your your PP is mounted.

Corrected ride file and profile attached.

John,
thanks.

1. i have no device/check calibration. i ve in spanish but no similar also. Is it possible under "analize" menu and then calibration check?

2. the new profile you sent is impossible to add or send to device.... it says " fric must be from 0,10 to 100"....and you sent me -1.249

3 . attach some images... i think is in the correct way,... always was in that place and i think has no problems.

thank you again

Do a new calibration ride, then post a ride file afterwards.

The Menu item: Device/Check Calibration is really Analyze/Check Calibration in Isaac.
