TT position help? anyone?
Don't make me make a thread with photos of me on the trainer...
Perhaps go this route and then sell the ibike or hold onto it since it's going to be way cheaper than time in the tunnel. You could probably use it during a race to adjust if it gets gusty and such.
yeah... no extra money so buying more equipment is pretty much out of the question. I use what is given to me.
I was hoping someone had a protocol that had helped them find a good position, but I guess I'll just have to invent one on my own I'll let you all know how it goes.
ze, go to biketechreview.com and check out the forum. It will have the low down on aero testing.
asgelle and pinky, thanks for the tips. Found some good info. If I can some good results I'll post up here
My parents want to buy me something for Christmas. I don't really want anything right now except a power meter. I doubt they'll buy me something expensive.
Something I considered is asking them for an iBike, and then I can pair it with a PT (or Quark) that I buy next summer when I have money. Is the only iBike that can do the CdA thing the newest iAero III? Are there cheaper (older) versions that are still ANT+ compatible and can calculate the CdA when paired with a direct measurement power meter?
I might ask for a Garmin 705 instead, which I can pair with my power meter when I get it. The CdA would be cool though, maybe I'll buy something to do that with in a couple years.
I wish they'd just pick a number and give me some cash.
The iAero +ANT Sport setup just lets you sort of do it "real time"...

"fixed" my slope -- it was reading 15.9 Hz/Nm, but according to my 2 gallons of water, it should say between 19.9 and 20.2. I went with 20.2 so that later, I can get free power if I underestimated the mass of the 2 gallons of water + bottles. I had called SRM, and the last time they say the meter was more than 3 years ago, and the number they had in their system was 15.9. I'm pretty sure there has been some drift.
Using this new calibration I went out to do a recovery ride after the 3200kJ epicness that was yesterday's ride. I arbitrarily picked 200W as my max/average wattage. Going uphill at 200W is painfully boring, but as soon as the road turns down, it seems like I have to actually work to maintain that number. I guess that's why people around here stay out of the hills on recovery days.
btw, this puts my max 5s sprint UNDER 1000W, which makes me cry a little inside. "I" think i'm a sprinter, but my 5 and 20 minutes numbers are much better on the chart. I haven't actually gone out to test yet, I'm just taking the bests from my rides. Tomorrow I'm going to do one or two "WRI"s (tm) to get a 1m number that qualifies as something besides untrained
So I did my 20 minute test on my cycle ops fluid 2 trainer on wed.
Take a look at this graph please. Is it too upward sloping? I mean, did I hold back to much in the beginning and then hammer too much at the end?
It seemed like at around 10 minutes it just got easier to hold higher wattage. And then the last 5 I just went pretty much as hard as I could go , within reason
So, I guess my question is, was this a pretty good initial test?
the actual test is from 41-61 minutes

So basically, you're not going to be at a loss if your FTP is a little lower than it actually is.
If you want, do a MAP test tomorrow and see if 72-75% of that wattage is close to 95% of your 20minute. If it is, then great, you're in the ballpark. You can retest in a month or so, but use the current number to structure workouts. If the 'hard' workouts seem too easy, then you know you've got something going.
Also, if you're holding 300+ for your 20 minute test, you're not warming up hard enough. Most of your warmup is in the sub 200 watt zone. You should be warming up in the 220-240 zone methinks.
