Cal numbers are completely off??

[GWPOS]

I am newbie and have been having many issues trying to get my IBike Pro calibrated and set up. At first I did not have the unit sitting flat on the stem so I resolved that by flipping the stem. Then I was doing cal rides on to hilly of an area. All of this was told to me by tech support. So today I went out and tried doing method 2 to get it calibrated but still got strange numbers. The first file has multiple cal rides going by method 1 and 2. The second file has EST AERO and FRIC set to yes and CRR=.0070 the way I was told to do it. I want a little more accuracy by doing coastdowns but then I get those bad numbers like CRR.0030 or something similar. If anyone has any idea that would help I would greatly appreciate it. I value my training time and have been spending to much time trying to get this working right (although at first it was my setup errors hindering me). Also to add in this is setup on a xc mountain bike with suspension FULLY locked out.

I have done wind cals and tilt cals before every attempt and still to no avail.

It's tough to get the setting right to do coastdowns on a mountain bike. The best bet is to let me attach a profile here where I manually adjusted your crr for you. What I did was to adjust the crr in the coastdowns and noted what it did to your cda. I then applied some riding tilt as your riding tilt was 0.0 (that's where the problems were coming from) and this will make a correct friction number.

To be fair, the iBike has never advertised itself as a power meter for mountain bikes. People have had some success with it on a mountain bike, but it's better to use a manually edited profile due to the conditions encountered during coastdowns.

Your profile is attached in this post. Save it to your desktop. The open the iBike software and go to profiles->edit profiles->import. Search for the file and then click "send profile to iBike"

You should be set from now on.

Thank you, I will load it and give it a try. I use this on a mtn bike that I ride on the road only, if I send you another file for my XC race bike whicjh I use only on dirt maybe you can look at it and do the same thing with the files?? As soon as I can get a road bike for training I will but until then I am stuck using what I have. I also know that this is not advertised to work on a mountain bike but I talked to John and he said he did not see any reason it would not. I don't plan on using this and expecting everything to be perfect, but as close as possible would be nice....whatever that may be. Thanks again
