I dont think I suggested it was - I questioned whether whatever the number was, be it 1, 2, 10 or 40 or more if the point being made was that if someone, all things being equal, did all the correct things - position, latex, tires, drive chain etc, they could ride at that much lower power and finish in the same time.

All correct.

And, what elite athletes usually do is, is ride at the same power as they did with the crappy set up, but instead finish much faster.

That is, if winning and collecting a paycheck is the object of the game.

Not sure what the pros do, but I have 1 set of training wheels and 1 set of race wheels. Training wheels: 32 hole mavic open pros with ultegra hubs and, yes, conti gatorskins in 25 mm (the biggest size that fits in my frame) with run of the mill butyl tubes. Race wheels: clincher zipp 808s with conti supersonic tires and latex tubes. I do indeed go lots faster on race day. Plus, it makes in easier to keep the race wheels ready and true.

actually,

i run my conti4ks on the same exact rims as you. on race day i run conti4k's latex on easton carbon clinchers.

so i should put gatorskins (25mm if possible?) onto my training wheels so it'll force me to work even harder during training.

The important number isn't 20 or 40 or 60 watts it's 25-95$ thousand. His coach also likely lost 10% of that.

You are right but that is only thinking of the prize money...I think the difference between 4th and even 3rd has got to be 100's of thousands in endorsements and publicity over the following 2-3 years. Podium=money, 4th=wooden medal and a lot of "you'll get em' next time conversations"..I know from experience there.

That's what I do.....I train by power, so I don't really give a crap how fast I go when I ask training. My wheels are basic alloy rim, 2 / 3x spoked wheels. Gatorskins 25c and butyl tubes. Bullet proof wheels that I don't have to worry about when riding.

Race my aero wheels w/ tubular steel go on, I ride my target power and I feel like am flying. Sure, it is only a little mind game, but I love that feeling on race day. Gives me an extra edge, IMO.

But it is not about pushing "more watts" on y training rides....that is just training by speed, which is pointless. I train by the same number of watts, but on race day, the result is extra speed for the same watts.

20-25 Watts is significant - 10w for me is an addition 0.3 mph ..... Lots of data to show this for my setup.... Not hard to determine what that means on a full IM distance.... Is huge.

Same weight, same or similar position on the bike, we assume he is using same helmet because of sponsor etc.

It ISN'T 40 watts LOL. Please show me the math. Another blatant example of great knowledge on Slowtwitch but an extraordinary lack of knowledge of basic Physics. You can't just backseat quarterback this thing and assume he has an extra 40 watts in his quiver and rides off the front solo to come into T2 5 minutes ahead. That's not how the pro race works. Sure we can argue energy expenditure and he runs a little bit better but that is so subjective.

Im not arguing that its huge low hanging fruit but its not 40 watts worth.


You can look up the watts saved via rolling resistance for latex vs butyl (2+ watts per tube) and 4000S vs Gators (8-10 watts per tire). So there's at least 20 watts on tires and tubes. Not 40 but 20-25. Not insignificant.

i do the same thing with strava ... if i'm doing a ride with serious efforts, i care about my watts on the segments i'm using. time is meaningless. i'm wearing flappy jackets, carrying a bunch of crap, on 25mm gatorskins, etc. speed means nothing to me.

Or he knew the Cannodale deal was on the horizon...sandbagged with the gators so he could throw down on the Cannondale in 2016. Sure it would be a gamble but makes a little sense in my conspiracy theorist mind.

Anybody look at previous year's photos to see if he was rocking them?

Perhaps he had a bad run with punctures? I've had a total of 3 flats in 4 years of racing, but all within 3 months of each other and two were a nightmare to change. Snapped a tyre lever and had an issue with a C02 tube so rode for 40kms on a tyre with about 20 psi! So I ended up with extreme puncture paranoia and leading up to an important 70.3, that was all I thought about,to the point I considered gatorskins. Slower, but peace of mind. I didn't in the end, I just made sure I carried extra CO2s and got better tyre levers.

No, it will just force you to be slower. You can work as hard as you want (i.e. Whatever watts you want to put out) regardless of your set-up.

Putting slower tires on your bike will not "force" you to work more unless you are training by speed and want to match previous speed (which is not how you should train) or doing group rides and need to keep up with others. Otherwise, if you are gaining by power, you will just be slower for a given ride / power level.

Sure,

I was only speaking of "knowns" Just like when Kienle flatted and basically lost 40$k or when Stadler flatted and dropped out ("too much glue!!!")

I remember when Peter Reid won Kona the 2nd time IIRC, it was rumoured that he had equal prize money matching contracts from 4 sponsors, IE something like 500k instead of 100k or so.

Basically I heard this 3rd or 4th hand, I don't know Peter…I don't think he won half a million U.S.$ (keep in mind back then it would have been 650k$Can or so)

But…he won something more than 100k$ prize money for his second victory…Just a guess but maybe we could split the difference and say he made 250$ or so…I could be off, just a guess.

You're right after third people tend to care a bit less.

If anyone has had a bad run with punctures, last years Kona aside, it has been Frodo.

No, not exactly.

I might consider pulling wide gatorskins on your training wheels, so you'll be putting the majority of your bike miles on inexpensive, comfortable, and flat resistant, if slow, wheels. Not because that will, by itself, "force you to work even harder during training", but because most of the time top speed is not that important during training. What is important is that you work (appropriately) hard. and also that you don't taco a $1000 aero wheel during a daily ride, especially when you really don't need to.

Gatorskins are a lot of things.....comfortable is NOT one of them. They ride like schitt, IMO. But super-durable and dependable, so I deal with it.

Sure, all other things being equal.

But a 25mm gatorskin at 85 psi on a mavic open pro is more comfortable (to me) than a 20mm supersonic at 110psi on a stiff carbon zipp.

why the hell are you riding 110psi?

i ride my 23mm conti 4ks at 90psi. if i ran 25mm gators, i might be riding 75 or 80..

per wheel at 18mph.....so on the order of 24 watts for 2 wheels at ~24mph for Potts. That's some really sweet low hanging fruit.

Sorry for the potentially dumb question, but why would you multiply it by 2...i KNOW there are 2 wheels, but they are both attached to the same bike. So if you ran 1 gator in front and a 4000s in the back, the rear tire won't speed up or be faster.
..
I am aware that the smart choice in my hypothetical situation would be to put the 4000 on the front.

That's not how it works. It's less energy used to roll the tire.

doesn't that go completely against information that flow published and tom A has mentioned on his site? i was under the impression that higher tire pressure will actually increase rolling resistance and the sweet spot was in the 90-100psi range (weight dependent).
