Switching iAero Head Unit from English to Metric

I was wondering if there is a way to change the display on the unit to use metric in this case without going through the Fast Start sequence. I don't want to have to re-do any settings or calibration changes in there, but I'd like to switch my unit over to metric. I tried editing the profile in the ...

Help Dialing In Profile Configu (using PT & iAreo)

Hello, I've been riding w/ an iAero and PowerTap for some time. Profile configuration is decent but iAero is consistently reporting lower numbers in groups but high numbers when solo and I just can't get my profile tweaked to line up. I take file after file, do tweaks to the file in iBike4 post ride...

Re: Advice on Optimizing Battery Life of iAero

OK thank you. I was only changing the battery because I thought it wasn't good if it dropped below 280. The system seemed to be working just fine even when the battery started dropping into the 270's, so I'll go by the battery check from now on.

Advice on Optimizing Battery Life of iAero

Hello, I upgraded from an iPro to the iAero several months ago. I run the latest version 4 of the iBike software and the latest firmware released back in April. Although I've linked it to a powertap in the past, I have that turned back off as I dno't use that feature very often. I use wireless speed...

Re: 2 Bikes, 1 Profile

Your points are well taken about re-doing the cal ride. I actually did that yesterday using a linked powertap and the what it said was that these are the new values: Aero: 0.353 Wind Scaling: 1.101 CdA: 0.320 Versus my existing profile: Aero: 0.289 WS: 0.877 Cda: 0.330 In any case, did a very standa...

2 Bikes, 1 Profile

So I have a road bike setup with a stem mount, wireless iPro. It's been working great. I just bought a new road bike. Same size, very similar weight. Wheels and configuration are all identical to the bike I've had. Just a new frame. Position is the same on the bike as well. So the question is, do I ...

Re: Refining calibration numbers

That's awesome. I'm buying that upgrade for sure now. Thanks!

Regarding the steps to use the iAero to perform that cal, is there an online doc with the details or is it pretty straight forward?

Re: Refining calibration numbers

Hi Travis, Thank you for the response. That is a huge help. I will give those adjustments a try and see what happens. Also, you peaked my interest on your last statement. Currently I have an iPro and a PowerTap. If I upgraded to the iAreo are you saying there is some way to use the PowerTap data to ...

Refining calibration numbers

So I've been running my iBike for about 6 months now. Works well. I've recently lost some weight and decided to just do another side by side comparison of it with my powertap. I'm close with the numbers consistently, but the iBike keeps reading a slightly harder workout than the PT. For example, a 3...

Edit Values Shown on Display?

Hi, I've got the iBike Pro, Gen 3 with the 4.03 firmware. I'm curious if there is a way to change what data is shown on the display by default? As odd as it may sound, I'm interested in hiding my watts and just seeing cadence, hr and speed for the off-season. Right now I have tape over it, but I was...

Re: Calibration Advice (issues with drafting numbers)

The manual edits really made a difference. Today's ride was the closet I've seen yet with a group ride scenario. I'm still tweaking the CdA up a touch for tomorrow, but now there's real progress. Thanks for all the help with this.

OK, novice question here but I go into Profiles > Edit Profile and then click Advanced Profile Settings in order to change my CdA. I then do so, hit the accept button (at which point it tells me I'm switching to a User Edited profile) but then the screen where I can send the profile to the iBike doe...

Re: Calibration Advice (issues with drafting numbers)

I did as advised, setting the CRR to 0.0055 and going out and coasting through some 20+ MPH speeds watching the watts zero out. Very interesting observation. Within the 20-25mph range of coasting, I observed the watts on the 'coast' screen drop negative between 10 and 25 a lot. That matches up very ...

Re: Calibration Advice (issues with drafting numbers)

So if I go into the Process Calibration Ride screen (the one I posted the screen shot of) and change the CRR value to a Fixed CRR value of 0.0055, it changes many of the numbers including Friction, Cda and Aero. I then want to upload that data as Profile 1 to my iBike and then go for a ride using th...

Re: Calibration Advice (issues with drafting numbers)

So with some help from CoachBoyd, I've gotten a lot closer with my data. With a stem mount instead of my previous bar mount and doing better coast downs, I'm now within 20 watts consistently of good data. For some reason the latest data seems to just be consistently 20 watts on average lower than my...

Re: Calibration Advice (issues with drafting numbers)

Would be interested in seeing some thoughts on these two concepts from the developers. I wonder what they might think is the better testing approach because I didn't even give a thought to this topic when doing my setup from what I read in the manuals.

Re: Calibration Advice (issues with drafting numbers)

Thanks. That point about the coast downs is something I think I really messed up on. I didn't think about re-using the exact same stretch of road to repeat each. In stead I just kept riding, doing some along the way back to back. This morning I went out and did a fresh wind and tilt cal and then 4 m...

Re: Calibration Advice (issues with drafting numbers)

So I have new ride data with a fresh calibration ride this morning (4miles instead of 2m) and 6 coast downs. The data is actually worse now than it was with my previous settings because even solo riding is off now (reporting lower than PT). The conditions this morning were very calm. The road was st...

Re: Calibration Advice (issues with drafting numbers)

I thought that was a high number too, but assumed that it was related to the fact that I have it bar mounted and sticking out pretty far compared to all the stem mount's I see. I'll run another o&b ride and some coast downs this morning before my ride and see if that helps at all. But I'm not op...

Calibration Advice (issues with drafting numbers)

Hello, Just got my iBike Pro Gen3 (bar mounted, wireless, v400 firmware) on Monday and have gone through all of the steps for configuration. I've been actively reading up on all the threads to make sure I have the calibration decent. I have a PowerTap as well, so I'm comparing the two (manually) to ...
