AeroPod, PowerPod and Newton

At one time, there was talk of a little guide being put together regarding Boyd's process for doing off-line comparisons between iBike and DFPM files for the purpose of tweaking iBike profiles. Has any progress been made on that?

Just to be clear - I'm not trying to see 'live' data from the PT on the iBike (though part 2 of my question is expressing curiosity about that...) My assumption is that I should be able to somehow do some after-ride analysis and comparisons between the iBike data and the PT data to dial the iBike in...

I've got a Gen III iPro and have gotten my hands on a wired PowerTap SL for a while. I'm interested in trying to dial in my iBike further, and I believe I've seen/read that you can do this by running some type of analysis/comparison of the iBike ride file vs the DFPM data for the same ride(s). Is th...

I sent my Gen III unit back to have a problem w/ the button looked at, and a new case (and display) were put on - nothing was found w/ the button, ironically... :-) (Incidentally, this was yet another example of Velocomp's high level of customer service - John convinced me to send it to them for a l...

of course now I've got to find a big-honkin O-ring that will wrap around my bladed fork leg for the Sigma pick-up...

Well, even w/ the pick-up taped to the magnet, no combination of any 2 pins on the mount would give me a continuous loop w/ the meter, so I took a leap of faith and lopped off the iBike wheel pick-up and spliced on an old Sigma Sport pick-up, and sure enough, the iBike is reading the wheel speed aga...

I've got a wired speed/cadence mount which has been working fine for years. About 10 mi into a ride yesterday, it started getting flaky - speed and power going up and down, then dropping out intermittently, then finally dropping out altogether. No amount of repositioning the magnet, the pickup, wigg...

My Gen III has not been responding consistently to middle button presses when in User Interval mode lately. I haven't noticed any lack of response when using the button in other contexts (ie, moving between functions, navigating through setup menus, etc), only when I'm in User Interval mode. I've ha...

Todd's file worked for me too - the driver that loaded w/ the iBike/Mac install didn't work. "Uninstalled" (manual PITA...) that original driver, installed John's recommended file, but no joy - The Great Mac seemed to think I'd installed and wanted to use a modem. Installed Todd's recommen...

larryt - what type of repair was done, and does it seem to have resolved the 'losing its mind when its wet' problem?

Ugh, yes, me too on this. Rode in the rain and had ridiculous power (and speed/cadence - I don't understand why these go batty in the rain??), but today, the roads are completely dry, I had the battery out and the cover off all night, no moisture under the window or such, and the wind offset is boun...

Ahh - ok, that makes sense!

Thanks for clearing that up!!

I LOVE the new absolute windspeed feature. I can't envision why anyone would want to use it the other way, but it is nice to have lots of features to choose from! :-) I'm a little confused by the reading though. I was out on a recovery ride yesterday, in low-but-somewhat-gusty wind conditions and sa...

Wow, thanks again rruf - I wish I had about 1/2 as much of a grasp of this stuff as you seem to have! :-) I'll try those numbers for a few rides and see how they go - I'm also going to go back and try to apply those to a series of past rides and see how things look. I'm in full agreement w/ setting ...

Another item of note - I took the profiles that were generated as a result of my still-in-some-question CD/4MRs last week (one on aerobars, one in drops, though I did them back-to-back and didn't download between, which is apparently a no-no). Anyway, taking the profile that was generated in the dro...

rruf - thanks for the detailed and insightful info. I agree, I need to wait for one of those rare calm days and do another set of CDs and 4MR and see where things fall out again. From what I've read on this and other threads, this does sound like a potential wind scaling issue. I did a ride today, a...

Its very likely/possible that I'm not realizing much aero advantage on the aerobars. They are intentionally short - I ride a regular old road bike, and use the aerobars mainly because I can ride on them for 10, 20, 30 minutes pretty comfortably, whereas I cannot ride in the drops comfortably that lo...

I've attached (I think... :-) 2 pictures of how the iBike is mounted on my bike. I have a diamond-section stem, and the Topeak extender wouldn't clamp to it (I tried), so I went the ghetto approach with an old mtb bar-end and an adaptor that I machined from alu. The air port of the iBike sits approx...

Boyd - I went out at lunch today and did two sets each of 5 CDs and 1 4MR - one on the aerobars, and one in the drops, just so there'd be something to compare. It was a little windy, but for around here, it was relatively calm, so w/o waiting weeks for an abnormally calm day, this is about as good a...

Heh heh, sounds like a deal John - put me down for the aquarium tubing - I'm sure our family fish won't miss a few hundred feet of that! :-) You guys truly do rock - great to see you exploring the options and limits of the setup. I think you guys might be onto something as regards keeping rain water...

Boyd - unfortunately, I lost my calibration ride data files a few months back when my computer crashed. I can export my current profile, but I don't know if that'll provide any value to you or not. On the .325m^2 value - you say that's a little low - do you mean a little high? (ie, I should expect m...

Ah, cool! Do I get a cut of the action on new TT setups, since I was proposing pitot tubes back in the good ole' Topica days?? ;-> (http://lists.topica.com/lists/iBikeProP ... start=2425)

I'm wondering if someone w/ some wider experience than my own can give me a sanity check on my iBike-calculated CdA value. Calm days are a serious rarity where I live, and I haven't been able to do some new CD's to check the value. My last CDs were last fall. I am 5'9" and weigh 138lbs. I have ...

I have to agree with you on the speed - it really is superfluous during the interval. (but it would be nice to see the ave afterward, if it were do-able through a sensible interface.) I personally rank cadence pretty high (and would argue its probably more germane than an instantaneous HR display - ...

LOVE the new User Interval feature. I have a favorite hill for repeats, and I like to monitor power/time/speed from one road sign at the bottom to another at the top. This new feature is perfect for this! (I was rankled by the abduction of he subtrip feature from the Gen II, but seeing ave and curre...

BTW, I downloaded and looked at the spreadsheet. Looks like good stuff, and good to know it was put together by someone who has a clue about intervals, vs my attempts to gravitate simply toward what hurts the most! What is generally considered a good mix of these intervals to do? My two goals presen...

Hi Boyd. Yikes, that's scary to think about, that old George is only 20 lbs heavier than I am, but can probably crank out 2-3x my FTP. I feel like an ant under a shoe - a very big shoe! :-) I've attached the appended file - I really appreciate you taking the time to look at it. Doing another fitness...

Went out today to try the fitness test (first moderate-temperature, not-insanely-windy day in a very long time here!). Did my first one heading out a road that is slightly rolling, but trends uphill at about .73%. Wind was kind of swirly, and looking back at the file, iBike registered it as about a ...

For whatever reason (no fault of VC's), roller power numbers seem to be hard to come by, and the only two supported 'out of the box' are Kreitler and E-Motion. Fortunately, we're able to add coefficients for trainers/rollers if we're able to gather some speed:power numbers (such as by borrowing a DF...

No doubt you guys have some good stuff coming up concerning intervals, laps, etc. (Heavens knows you've heard enough whining from us on these items... ;-), but you're killing me w/ this 'wait till you see this' stuff... :-) When can we (roughly) expect to see this sure-to-be-wondrous firmware update...
