AeroPod, PowerPod and Newton

the manual calibration is no fix either

my PT wheel is going back to Saris for service -- the torque values are way off, giving power ratings that are around 10% off

uh...my iBike was more accurate...

all these gizmo things have their issues

aha

I got a wheel on a discount and didn't get the PT head unit because I had the iBike

so, my numbers are pretty much rubbish until I buy a PT head unit

more money out the window then

so the pcal procedure is not effective in zeroing the torque?

feature request, then -- how about a setting for DFPM users to see raw torque values, so we don't need a second gizmo for calibration?

I don't have a PT Head, just the iAero

I do the Pcal before each ride

How can I check if the PT itself is drifting -- since the "Stomp test" isn't possible with the iAero?

Been getting great watts in training...just want to make sure it's me, not the gadget going wacko

john -- boyd did an awesome job editing the profile to get the two PMs dialed in my concern was whatever glitch was going on with the profile when I changed the FTP to 355 and tried to send it to the iBike -- the dialogue box came up that the rider height value was 0, then another box came up that s...

same issue here

97 miles for this ride?

also, when I tried to adjust FTP up in my profile, it said that there was no height entered, and would not send the profile to the unit

I haven't had a good non-windy, low-traffic day to do a DFPM cal ride with my iAero, but I've done a few outside rides with it and the Power Tap Pro+. Easy level 2-3 rides, the watts are very close -- the iBike a little low, but within 10 all the time. I did a sweet spot ride -- 45min averaging 315w...

I was sceptical of the power numbers I've been getting on the trainer -- 330-340w for 2x20s I did an hour at 315 on a properly calibrated computrainer a month ago and HR+PE were in sweet spot territory, which seemed to validate a 330+ FTP the Kurt is a mystery. To pass the squeak test, it needs 4 tu...

Yeah -- the KK. The main reason I took advantage of getting a PT Pro+ wheel through my old sponsor shop was to make sure I'm getting accuate watts on the trainer. 90% of my winter and fall work is inside, and there are too many variables with the trainer mode on the iBike. My iBIke outdoor power rea...

I've seen a 10-20w difference at FTP if the back axle isn't snug against the tire. When I first put this winter's tire on, it only took 3 1/2 turns to pass the squeak test -- hold the tire at top center, rotate 1/4 turn, then smoothly -- in one motion, but don't jerk it -- rotate forward to the star...

I've got a PT wheel coming in to use now and then with the iBIke

looks like rain on the days when I could get out to do a cal ride

will it be fine on the trainer until I can get the cal ride in -- just pair it and do the grunt work?

go to device

"connect"

duh

works fine

I installed the Windows 7 driver and iBike 4 software on a new laptop, but when I try to download ride data I get a prompt that says the unit is not responding and needs to be connected to a com port in the 1-64 range. I tried plugging the USB adapter into each of the computer's 3 USB ports, and I g...

The best FTP figure is for a rested, all-out 60min effort.

Otherwise, the power that you can regularly and consistently produce during your 2 x 20s, 2 x 30s, 1x 45s, etc.. is a reasonable indicator of FTP.

you can do that without the PT head unit mounted?

I was leaning towards the Quarq for those reasons, Boyd -- plus I've always dug Jonathan's. The original plan was to get the iBike as a head unit, then the Quarq. The rub is that price -- there's a good deal out there on SRAM 175s, but I use 172.5s -- 300 bucks more. For the price of that 172.5 Quar...

Looking over the DFPM instructions, the Quarq seems more user-friendly -- just backpedal 4 revolutions and do that occasionally during the ride. The PT looks a bit more trouble -- longer calibration sequence pre-ride (unless you want two head units), and then needing to rezero the torque throughout ...

great work john

flogging myself with your product has helped me go from 325w@FTP (71 kilos) in September to 335w. after some VO2 work in Jan-Feb, maybe I can put another 5w on that before the racing starts.

I dig this little black gadget.

the e-motions are pretty tempting

any word on whether the tru trainer power curve will be in trainer updates?

I dig those, but if they're not compatible with the iBike trainer mode....

was on the back porch tonight fan on from the start -- trainer mode cuts off after 30min checked cal wind in setup -- it was way off. did another wind cal, it worked fine for another 25 min, enough to finish the 2nd of a 2x20 can the wind offset drift when the temp drops be fixed in the new firmware?

I'll second the DFPM recommendation. I've done that for trainers to create a spreadsheet. )Ou could then manually enter the data into WKO+.

man, thanks fernando

something must have been loose from the bike being on its side in my hatchback

all the charts and graphs whack my brain out

the more I have to possibly confuse me, the more confused I'll get

if the wattage numbers check, that's all I need to know

I'm noticing 1-1.5 mph tailwind averages, now that I look at other ride files

should I load the new profile into my iAero, and change the profile for these files?

or, is the profile correction only needed for the Nov 3 ride file?

how do I open that file?

I'll check the wind scaling in my profile when I get home today

I haven't had this kind of wind reading before -- what may have been the likely culprit?

tuesday night ride

closed 1 mi loop

average 1.4 tailwind??

what's up with this?

bike was on it's side in the back of the car for 15min on the way there...then maybe not a full 10min to adjust to temp. The temp data is off -- ride started at 64 and dropped to 57 by the end.

is it wind scaling?

thanks man

i guess the solution is just to not stop

urination is so 2009

I'll try moving the trainer back a few feet from the fan -- it was closer tonight than its been, now that I think about it.

I'm a hot head/head case.

Their customer service has been super so far.
