Re: DFPM calibration -- Power Tap

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

Re: DFPM calibration -- Power Tap

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

Re: DFPM calibration -- Power Tap

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

Re: DFPM calibration -- Power Tap

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?

DFPM calibration -- Power Tap

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

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

DFPM and iBike power difference in short efforts

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...

Re: trainers

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...

Re: trainers

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.

Re: trainers

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...

DFPM on Trainer sans Cal Ride

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?

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.

Re: Quarq vs. PT with IAero

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...

Quarq vs. PT with IAero

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 ...

Re: What's your fitness score and watts/kg?

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.

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?

Re: weird wind readings on closed loop ride

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?

weird wind readings on closed loop ride

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?
