Re: What is wrong with Power and Slope data?

Your tilt is off by a country mile. "Normal" tilt is about -.5, yours is -50.9! Additionally, your wind scaling is way off IF these are essentially out/back rides. Attached is a more normal profile however, I suggest you do a real out/back cal ride to nail down the wind scaling. The excessive slope ...

Re: Wind data might be off???

Glad it all worked out! I honestly don't have any idea why the wind was off on this ride. But it makes sense that based on your previous statement I did check Out-and-back initially, but when I did that the power numbers jumped and I saw an average increase in power of about 30W for the whole ride. ...

Did it feel like a 133w AVG or 166w? You can certainly tell the difference between those two numbers. You did the same thing I always do. I do not check out/back because that forces the wind to about zero. Entering the start/end elevation only makes a minor adjustment for any changes in barometric p...

Agreed, the wind seems low. However... 1) How much vehicular traffic did you have to deal with? A roundabout means you were on roads with cars. It's amazing how much the wind is pushed along with you by cars. 2) Check your wind port. About once a year I GENTLY clean it with a Q-Tip. Give it a rap ag...

Re: Isaac detects drafting when no actual drafting

If Isaac sees a period of time with a substantial tailwind it will assume you drafted.

I personally have no boxes checked and I enter my own starting and ending elevation. The results are absolutely consistent and repeatable.

Re: TT mount without RWS

You might be OK as far as the wind port goes but you need to be very careful how you mount it. If you mount from one of the aerobars I'm concerned your pulling on the bars will skew the the power numbers. Note that the end average results as far as AP and NP will probably be correct because the Newt...

Cal ride should be used on the subsequent ride which should be identical to the cal ride. Do a cal ride, turn around and do the same ride as an out/back.

Re: Tilt measuring and repairing bad tilt eide

Do a regular ride and at the end of the ride press and hold the center button to reset the ride.

The next time you do a ride, check the tilt as you have previously and it should be correct.

However, I can't remember if it does this auto correct after a ride or only after a cal ride?

Re: Wind Question & how do I correct it?

I still think you're overestimating the wind effects in a cross wind situation. Granted, crosswinds can be a challenge but I think mostly because our body tends to disturb the wind flow as it gets to Newton. However, I still think the difference is minimal and not something you should make correctio...

The difference between a winter setup and a summer setup is not significant. Look for a 40 degree day (may not be possible where you live) and do your cal ride. The results will work just fine.

IF you know what the difference is in Crr between the 23 and the 25 you could go into edit trainer settings and click on the coefficients tab. There is a Crr setting there.

When on a typical ride on this bike do you generally ride in the aero position? I would assume yes, otherwise you wouldn't bolt the bars on to begin with.

Re: Isaac feature request

Although a 60 minute best might be on either side of a coffee break, I doubt this kind of 60 minutes could ever match a steady state 60 minutes alone. The time spent getting back up to speed after a coffee break will seriously cut into the average.

There is no need to press any button. Newton stops recording when you stop.

Of course the ride you completed is still in memory. Th...

Re: Wind scaling

The short answer is it's applied to the unit. The longer answer is there are two "wind" names. Wind Scaling is the math needed to balance out a true out/back ride so the wind speed equals zero. This number is stored in the profile and is "usually" in the .9 to 1.5 range if the iBike is on the stem. ...
