Never seen any conditions where a bike is ridable but a disc isn't.

" In a crosswind (particularly when it’s gusty), more energy "

No actually, less energy is used...

"Always use a disc" has been replaced with "Always use a pull buoy"

Sutto says crazy stuff when it comes to basic physics or basically anything to do with science. He may know how to get a lot out of some athletes, and produces champions, but that's in the void of any application of physics when it comes to moving a bike through the air. There are much better resources on this forum who are just regular age groupers who know what they are talking about. Listen to them!

The only way I can square what's he's saying re wheels/discs are:

1. He is predominantly focused on Kona, where discs are not allowed.
2. He is predominantly focused on long course, where it is def true that the time you will lose messing with a flat inefficiently will far exceed time lost to 2nd best aero wheels

Fair enough in my count. Although I do think it's probably a bit much to say that you have to be 24.5mph (40k/ph) to get disc benefits when the physics don't agree with that.

 Is it fair to say that his statement about using a disc wheel will beat you up more for the run, or you will have a worse run, also not true? I don't remember reading these kinds of claims in Joe Friel's books or really any book that I've read.

He should become an ENVE rep and just talk everyone out of disc wheels.

Or perhaps they could partner with Silca, Rapha, et. al. for a super exclusive wheel cover

“You are experiencing the criminal coverup of a foreign backed fascist hostile takeover of a mafia shakedown of an authoritarian religious slow motion coup. Persuade people to vote for Democracy.”

I just read his article and I thought it was right on. I see folks trying to read stuff into what he wrote that I did not see written. I thought he made a lot of great points.
And on the disc wheel, I have had the same type of thoughts. If you do have a flat, and it is a pain to change, maybe an easier wheel to deal with is worth considering.

Changing a tire on my Jet disc is no different than any of my other Jet rims.

Disc wheels that aren't solid (HED Jet, Flo, etc) won't beat you up any more than any other spoked wheel.

Just seen this picture of his latest super star riding a disc getting ready to crush the 70.3.

I don't necessarily disagree with everything he says - there is more to life than spreadsheets when it comes to race day - but I tend to think he could do more to make his pro's more skilled at sorting out their own mechanicals. Remember Chrissie at the side of the road trying to fix a flat in Kona? That was simply poor prep in my opinion.

He who understands the WHY, will understand the HOW.

"He should become an ENVE rep and just talk everyone out of disc wheels. "

This right here!!! love it

I heard she made that change on her own with her coaches approval.

I'm just going to start doing brick workouts with my disc. Can't trust anyone anymore with adivce; just have to try it out.

I call BS on changing a flat. My Jet disc is no different than regular Jet and a disc doesn't need a valve extender.

I think the only time that changing a flat on a disc could potentially be more difficult is if you are using tubular, and your spare isn't properly stretched. With normal/deep rims, you can put your toes over the rim and yank the tire up onto hit. With a disk, pretty much have to push with thumbs.

Sorry I only got as far as this:

I’ll respond to the question on tyres first as this is the least complicated. My opinion is that for Iron distance racing the choice between tubulars or clinchers shouldn’t be based on which one is faster.
Instead it should be on:
1. Which one you can change with confidence.
2. Which one you can ride with confidence after you have changed it.

I didn't read anymore. The guys a fucking tool.

And please correct me if I'm wrong, but is this whole "using discs in wind = dangerous" some urban myth? I've never had any issues with my Renn or Zipp 900 and I've had it out in 30kts plus crosswinds. My 808 front, on the other hand gets moved around plenty...

I wouldn't call it an urban myth. I'd call it incorrect intuition.

My thoughts on disc wheels and any aero wheels is that if your gut overhangs your shorts you should think about losing that before buying anything aero or lighter

It seems to be an incorrect intuition that is part of the rules of the sport though. I got stopped from racing a local half-distance race at the weekend due to having a disc in moderately breezy conditions, but 808s etc seemed to be absolutely fine. I was trying to explain the lack of logic to the race director with little success, who was just saying it's in the rules and he can do it if he wants....

Yes, never understood anything about not using disc wheels.
Anybody that has ridden them knows that it is simply not an issue in windy times.

Front wheels like an 808 on the other hand can scare the pants off me.
