Profile question

[whftherb]

When you do a 4 mi O&B for calibration, is that the only ride that the iBike should contain? IOW if I have 3 rides saved in the unit, how do I call in the 2d (middle) ride to use as a calibration ride for profile purposes? There doesn't seem to be a way in the iBike software to discreetly cull out a particular ride file for profile construction. Right?

Here is where you select which ride is the 4 mi ride:

The software tries to automatically pick the correct ride for you; however, you can change the selection with that contol.

So you can go out to do your coast-downs and 4 mi out & back and then take off for a longer ride. When you get back to your computer, you can process the c-ds and 4mi ride, create the profile, accept it, and then you can apply that new profile to your longer ride using the menu item "Tools -> Switch Profile after the Ride..."

Trav -

In that screenshot, where the heck is that panel you're showing me?

When you click on Profiles > Download Coastdowns, that is the window that pops up. You get asked if you did a 4 mile out and back and then the software downloads the coastdowns and the rides. It tries to pick the 4 mile out and back in case there were other rides.

OK, I see it now. But I've visited this screen before and the right hand side is greyed out (that's why I didn't recognize it in the post above). Downloaded all three rides (again) and still I don't have the choices on the right hand side. All I get is the first (7 mi) ride I did to warm up. I don't see the middle (4 mi) ride anywhere though I do see that the software sucks in all three (1 of 3, 2 of 3, and so forth) as the download progresses. So the iBike software is acting different than what's showing in the calibration screen screenshot.

So then, how am I going to get down to that second ride? I thought of eliminating (deleting) the 1st and 3rd but there's no ability to do a selective delete - it's all or nothing. Any clues?

If you see "1 of 3, 2 of 3, 3 of 3" as rides are downloaded, then all 3 have to be there. You have to click on the "v" on the right of the "Select 4 Mile Ride" control to see all the rides.

Another possibility is that you didn't push the ride reset button on the iBike after the 4 mile ride. To complete the ride reset, you have to confirm by pushing the center button a second time. So maybe what is going on is your 4 mile ride is part of a longer ride file. Use the time stamps to figure out which ride it is, and then you can select the 4 mile ride by clicking and dragging on it in the graph. Use the elevation profile to figure out where to start and stop the selection.

Hi Travis. Thanks for your assistance.

I'm pretty sure I did the trip resets correctly. Here's the deal. There are in fact 3 distinct, discreet ride files in the IBike. I know this because in the opening screen, when you "Download Ride" which opens up the "Download Ride" subpanel, indeed the 7, 4, and 11 mi rides come up (after downloading the set). There are tikmarks to select the one to view so I know there are three seperate files because I can clearly see them in this screen and otherwise logically the software wouldn't say "1 of 3, 2 of 3, 3 of 3" when downloading. All three are stored on disk now.

Now, when using the "Profiles" > "Download Coast Downs and Calibration Ride" feature, I hit the "Download iBike Data" and again all three rides get sucked in as evidenced by the same 1 of x dialog. And the 7 mi ride (the first one in the set) is what shows on screen. The right side is greyed out, I have to choose the 7 mi (and incorrect) ride. There is no ability to choose the 4 mi ride or extract it from what's showing on this screen becuase "it" doesn't live inside the 7 mi ride data.

I don't know the rule but I suspect that the calib ride must come from the iBike and cannot be called up from the stored rides in the computer (WindowsXP) on disk. Otherwise, it'd be easy. But I can't find a way to do that either.

I just noticed something! I've attached a screenshot of my own. There's some co-efficient data missing. Is this the problem??? I think it's not but want to be sure to cover all bases.

Any other thoughts about this? This also tells me that on the next rev, there ought to be a way to selectively delete ride files from the iBike as a way of working around this. And someone might think about installing the ability to construct a profile and send it to the iBike from ride files on disk.

Did you do any coast-downs? You are on the page for processing iAero + DFPM data. You need to select the "Coast-Down" tab, which you can see in the screenshot I posted. (It is cropped out in your screenshot.) If the Coast-Down tab is not available, that would indicate that there is no coast-down data in your unit.

The CDs were done on 7/22 - in fact there are (were) 2 of them with about the same numbers. What I was trying to do was get rid of the 7/22 profiles and replace with a better one (now that I read the instructions...ahem..).

Anyway, this is a dead issue now because I sucked it up, and redid everything this afternoon. Tightened iBike mount - cinched it up good and tight, wheel circ actual measurement, nice day 76 degs, let unit sit outside for 30 minutes, tilt cal, wind offset. Did 6 CDs right in a row, no "bad" ones according to iBike. From the point of the last CD, ran out and back 5.6 mi slightly breezy day but almost no cars, very little effort in pedalling, some moderate hilly terrain at the start/finish, held position well and most of the route is tucked down in the trees somewhat. Made sure to do a trip reset before dismount. Came directly in the house and fired this data into the software. Dumped out 2 7/22 profiles and now the 8/4 profile appears to be the default and it all plays together nicely.

38 mile ride later this evening with the local shop crowd. Got severely hammered and dropped after an hour or so. Cruised home. Numbers at intensity are lower than before today but they are smoother and I think they now are more accurate. Or at least as accurate as I'm going to get them. Note: I'm surprised at how "spikey" the power chart turns out but I guess it's the way it is.

Shoulda done this at the start before whining! Apologies to you Trav...
