So according to FLO's website and the wind tunnel results, if I average 20 mph, the disc will save me about 47 seconds over a FLO 90 in the course of a half-ironman.

It's more than that thanks to power to rotate. Flo data only gives translational drag.
Plus - getting faster is about making lots of little decisions that help towards the goal:
Don't eat that brownie
Don't kill the alarm and roll over
Use evidence based training methods
Work on your bike position
Make smart equipment choices (like IA vs some of the other options)

Tell me then, why so many pros were racing without a disc at the 70.3 World Championship? Why doesn't EVERYONE race with a disc in the events that allow it?

Being good at training and making smart equipment choices are not necessarily things that go together.

What kind of wattage differences are we actually talking here?

EDIT:
And do you know if this still applies to wheels with covers?

Also trying to choose the right size for an IAx (the IA 14). My first tri bike. Got fitted to a stack of 559 and a reach of 433. Focussed on long distance for next year, so maybe for shorter distances and after getting used to this position I can get just a bit lower. Should I get a 56 or a 58? SuperDave, what are your thoughts on this?

Ha! I thought you were giving your pad stack and reach. I was certain you'd be a 48cm.
On the IAx you have the option of a very low pad position because of the clip-on nature of the aerobars. I'm still struggling to illustrate just how adjustable the front of this bike is. More than 100mm of vertical adjustment is possible from lowest to highest position.

The 58cm frame has less aerodynamic drag over a -20/0/20 sweep and the longer wheelbase aids in a stable, straight-line path.
I would recommend a "slammed" front end on a 58cm over a 56cm with 2cm of extra bar stack, 2cm more pad reach on the extensions with more of your rider weight over the front wheel.

It sounds like your inexperience with triathlon position might also better be served by the 58cm because it will allow for a upright posture as you acclimate to a "textbook" position.

In general on the IA, go as big as you can without going too big as the slight aero hit of the smaller frame cannot offset an upright parachute position if you could have tolerated/adapted to a lower posture.

Hi Dave, will I fit on a 56 IAx with the stock bar & stem? My pad coordinates are 625(including pad)/500(mid pad).

But doesnt't the enormous surface area of both the IA frame and disc wheel make you an enormous victim to crosswinds?

No.
The bike's sidewind handling is better than bikes with less side-surface area and lower stall angles.

Brilliant, thanks for your quick reply! So The 58 will still give me enough wiggle room to go even lower in the next years?

Just to chime in on this (sorry guys if it's a bit late) but the wheel choice is based on the conditions, race director equipment restrictions, sponsorship and course profile. I think at the 70.3 WC there was a lot of people who chose to go the route of less weight due to the large climb that was on course. Also when courses are technical it takes a bit more effort each time to spin a disc wheel up than a lighter one so you may benefit from not using a disc.

In the end I will say the Flo 90 with Disc cover is a good option rather than not having another rear wheel besides the disc. That being said I've yet to encounter a course here in Ontario (Toronto) that is better without a disc cover (which is what I use on my IA). In cross winds you won't notice the rear wheel because you'll be too busy with the sensations of the front end being "nudged" in the direction of the wind. The bike has a feeling of forward encouragement as it acts like a sail "lifting" you up in a way. That's what they claim anyway and I'm yet to average 40km/h on any other bike so I'm inclined to agree. Don't wait for a disc cover or wheel because you have to earn it, just get the equipment you need to optimize your budget and performance evenly.

Do retail shops have the IA10 or IA14 yet? I know they are taking pre-orders but can I go look at one at my local Felt dealer or is that still a month or so off?

Trisumai noted they will be receiving theirs Oct 22nd. Is this roughly the earliest we should expect anyone to have one in hand?

Difficult to know how much faster Rinny could have run last year but Ryf certainly left some time on the bike. Watch this year's bike leg and compare. She's adopted changes to correct many of the observations people have made since last year.

That depends on how low you are now. You just gave me frame stack reach, not pad stack reach. There's lots of wiggle room but if you're already on the ground floor, you may not be able to go lower.

Superdave,

What frame size would you recommend in the new IA for these coordinates?

Arm pad reach 490 (back of pad) so probably 510-520 to center of pad
Arm pad stack 596 (top of pad)
Saddle height 779

Thanks,
Gareth

Woops, sorry. Completely new to this whole bike fit world and its terms :-)

My arm pad stack (BB vertical to top of arm pad) is 677. Arm pad reach (BB horiz to back of pad) is 430.

IA 10/14 have not arrived in the US, yet. Mid Oct is the current ETA to our CA warehouse.

I see listings on some international vendors but I haven't found ant photos of an IA16 yet. Not that it really matters since I've already placed my order for an IA10. I can't wait to finally have a real tri bike!

Gareth,
You'll be on a 54cm with 20mm risers and depending on the rotation of the base bar (horizontal or angled up) perhaps 0mm, +5mm or 10mm spacer under the 20mm threaded riser.
