TT bike power pod check

[andrewkerr1991]

Hi John, or anyone else who can give their opinion on my ride file.

I used the PP for my first club 10 TT tonight, the power readings i saw seem quite high. I have read on the forum that normally the wind scaling for a tt postion is different, but the wind scaling factor is very similar to what i have on my road bike profile.

I done an out and back calibration on the TT bike in the tt position etc, the PP is mounted on the handle bars as normal under the tri bars so nice and solid mounting.

Can someone give the file a quick check over and let me know if they think anything needs to be changed on the profile ?

thanks again.

I think your power readings are high; we are checking something in our FW.

Stay tuned...

We are doing some additional checking.

In your TT setup (Device/Device Setup), what values did you select for:

Ride position

Road surface type

Tire pressure

Tire size

Tire Grade

In the tires and road type window, did you uncheck the "Use Typical Settings" box?

Hi John,

Ride position = time trial

Road surface type = Good asphalt

Tire pressure =110 psi

Tire size = 700 x23c

Tire Grade = premium

In the tires and road type window, did you uncheck the "Use Typical Settings" box? yes i deselected this check box and entered the above i have tubs on my time trial bike this is why.

hope this helps.

We've done a lot of investigating, and have discovered two TT-related bugs, one of which affects you (firmware bug).

It will take a few days to get the FW update out, but in the mean time I've corrected your ride file and also your profile.

Until we get the FW update out there, you may still see high watts when racing with your TT bike. However, you will be able to workaround this problem with the "Analyze/Analyze Route..." command.

The other is a software bug, for Isaac Mac users only, which affects profile setting for TT bikes only. Since you're using Isaac for Windows, this bug does not affect you.

Hi John,

thanks a lot for looking into this for me. Its much appreciated.

i will load the profile on to the PP and see how it goes. I will wait for the FW update.

As always i appreciate your feedback.
