This video was blocked by the IOC. I claimed 'fair use' under the copyright ordinance and they've released it on the grounds it's for educational and review purposes. Hopefully it stays up. Cheers.

“Disc brakes don’t seem to be slowing anyone down” 🤣 Now there’s an advertising slogan

None of the racers could afford the oversized jockey cages and wheels. Great video as always. One thing I will point out that PROS cannot do is grow a gut. The gut provides more of a foil type shape and reduces dead air behind the aerobars. Also lean cut muscle at 6 percent body fat produces turbulent air in the worst places above the UCI mandated mid calf socks. It likely cost Dumoulin the gold.

I know it won’t happen, but I’d love Tom Dumoulin to get in touch. There’s clearly some man love going 😍 Great vid, super interesting (to us geeks).

The bikes they are riding are indeed S-Works but they are branded Specialized instead for the Olympics. They have done it now for the last 3 Olympics, I presume for a wider audience exposure or some Olympic branding rule!

Tom D's custom setup couldn't be made. Jumbo said : no time to make them in time for Olympics. Kudos to him he shrugged it off and pushed on, mentally he's in a better place now.

Dumoulin was always a TT specialist until he shocked everyone by becoming a climber in recent years. I think we'll see a return to focus on his favourite discipline now

Cross over with Lantern Rouge pls. Best commentary and tech analysis needs to come together.

This video is a fantastic blend of school and hobbies for me. Thank you for this level of detail. Much appreciated.

more videos like this! this was BRILLIANT, to the point and with some really great analysis, cheers mate!

Loved this video! Thanks for the great content 👍

Good stuff. 👍

Fantastic vid. Love PT's content. The most dead pan guy on KZfaq. It's incredible to see the evaluation from Jan Ullrichs Bianchi TT bike setup, with bars down style to today's bars up. His wrists were on the elbow pads back then!

Excellent analysis. Great video!

Awesome analysis, looking forward to more videos like this!

S-Works: it's one of those rules around sponsorship on equipment in the Olympics I believe.

Outstanding video!!!!!!

I love your TT ‘s videos.

Really good insights there, keep it up!

Nice little dig at the end there! Love it

good shit as always PT.

Outstanding review of the TT from a tech point of view!

More of this kind of content please 🤩

I would love to see this kind of analize for Roglič and his Cervélo setup. He won the race so it must be spot on.

I’m glad you brought up IBS. It’s important we speak about such things.

Superb analysis.

Afaik, that POC helmet + heat = death :D I only saw one rider in the women's race rocking one. Might as well check if she is still ok.

Very interesting analysis that. Any comments on long sleeve v short sleeve, gloves/no gloves?

Thank peak torque awesome vid I've been thinking about trips and vortex generators on my TT bike and helmet my theory was to trip the air off the back of arm pad as my legs are just behind and also triping air on helmet behind the ears b4 the shoulders glad to here that I'm not just wishful thinking

Fantastic video

Great Video. The pros seem to want the XTR rotors as they are 12g lighter than DA. Some anecdotal testing data from Parcours that they might be more aero (less than the margin of error tho). Oversized pulley wheels: pay $500 to gain 0.5W friction efficiency, lose 2W in aero. Best bike bling scam ever (and I bought some once! ;-)

The Best Tech Drafting your mate during the laps into the finish

Depends on you local dealer here in Japan. In our city, the dominant bike shop carries spesh/sworks/cannondale/pinarello, so pretty much every club ride, those are the brands youll see (Im the only rogue canyon rider at least in our city). The neighbouring city is more like trek/giant.

Specialized labeling is just like Olympic edition Shimano equipment, for brand exposure opposed to niche model name exposure

The only reason to energize airflow is if you're hoping to get it to reattach/stay attached longer to a plane that is at too steep an angle for the flow to remain attached otherwise. In the case of the legs that would need to happen right before the natural seperation point. Otherwise the only other lever to play with is pressure drag management, but the bars are way too in front of the legs. Dumoulin's extensions on the other hand would work in this reguard, but I don't know that they could be assumed better than molded extensions.

how do you feel about uphill/downhill/flat coast down tests for riders who dont get to use wind tunnels or have access to pressure rakes or other attached gadgetry? do you have any advice for a test protocol you think might work for riders who get to play with just a bike and a gps or stopwatch.

Great stuff. On the Olympic theme, any thoughts about the stem failure on the Aussies' Argon 18 in the team pursuit qualifying rounds?

I appreciate the focus on bigger riders.

Small frames are awesome frames. Another benefit is the shorter wheelbase makes them feel more reactive to body positioning but you tend to run them with longer than usual stems which dials out the twitchy characteristics. The more extreme drop makes the body more aero as well. I think Gilbert used to ride a 48cm for a while even though he is 5'10." There is a picture of him drafting behind a BMC car that looks crazy with how tiny the frame is.

How many oversized jockey wheels do you see in the top ten? LOVE IT!

Super video and analysis, very well done. Changing the subject slightly (as well as a bike geek i'm also a watch geek!!)...is that a seiko skx pepsi on your wrist?

Agree, the spesh basebar looks huge!

Interesting video, I remember Hambini mentionning the gap ahead of the backwheel on the specialzed as being bad as well. By the way, anyone has news of him? He's been pretty silent lately.

For the Shiv TT bike. I think Specialised tested with and without the cut out and it made no difference aerodynamically so they got rid of it to decrease frame weight. I'm not convinced but it is still a fast frame

Ganna appeared to be running Conti TT tyres with a GP4000 tread pattern, would love to know where those are available to buy 🤔

So, T-rex were great time trialists in the dinasour kingdom!! Amazing observation. 👍

"disc brakes don't seem to be slowing anyone down", I lol'd at the irony.

Re: speed wobble - I recently moved to the Med. Some surfaces on the quieter paved roads are pretty dire. Including deep, high frequency washboard on very steep hills ... which is nightmarish descending - particularly as a heavyish rider (85kg). The lack of traction for braking means you have pretty much no hope of stopping if you aren't heavily dragging the brakes from the get-go. But even then, given how steep some of it is, you're subject to speed-wobble at low speeds as you have to be hard so hard on the brakes & you're getting thrown around. Then you have to deal with locking up the rear as soon as the rear tyre finds any traction. Any tips at least to mitigate the speed wobble? Haven't balanced my wheels ... but not entirely sure how to approach that anyway with tubeless - doesn't the sealant make that impossible?

Your ment to say spoiler alert before the spoiler lol. Kidding though exceptional content

Loved it!

Probably been asked before, but what model is your watch?

I suppose specialised used the full name as norms watching cycling may of heard of them but s-works unless your a cycling fan probs never heard of them. The cut off around the rear wheel I found strange as all aero bikes used to have them but in the last year with the migration to lighter aero bikes most bikes have changed now. I find it rather odd as the TT bikes mainly still have them apart from specialised 🤔 Enjoyed the video great watch once again

Best way of killing a speed wobble is to grip the top tube with your knees. Presumably this has the effect of increasing the stiffness, and therefore the resonant frequency of the system.

What about met drone wb helmet? Do you think it works?

Regarding the wide base bar. As it doesn’t really control the shoulder position for a great period of time unlike a road bike drop bar. The extra 2-4 cm^2 of area is in the nice aero section of the bars so is probably quite a small drag penalty for the extra benefit of improved stability whilst descending and leverage when out of the saddle.

Wow. Your videos are really good. Needs a little more swearing though. Cheers !

Actually I noticed some of the women were running S-works in the road race but indeed none of the men.

Hi may I know what do u think of the winspace slc 2.0 vs Ur tcr advanced sl

Cheers 👍

If you could cover the track events especially team GB's bike

Are you telling me my £400 jokey wheel wont make a better cyclist???!!?!?

There was also a big factor: The riders who dug deep in the Road Race paid the price. From those who were in the fight for medal in the RR, only 2 made in the top10 (WvA and Urán). The design of this race favored GC riders so they could rival TT specialists.

I can't wait to see what the new Hope Track bikes can do along with the new track chains. Are these developments for real, or a bust? We may see starting Monday!

If there were no rules what would you change on an upright bike? I wonder what would cross over well from the recumbent world.

The important fact is that if they where ghost riders their aero helmets would melt due to burning skull heads instead of regular human heads ,, not aero

Could you do a video on the Y250 vortex an how it could and should be used in cycling

The guy in orange at 16:06 seems to be wearing some kind of aero cod-piece, what's that all about?

I was actually wishing they’d just use the full Fuji circuit for the TT considering they cancelled the FIA WEC race there. Enjoyable competition though

15:12 Is riding full mast an advantage?

Dennis actually looked to be riding an Aerocoach Aeox ultra disc. The other Ineos boys were still on the Princeton disc

Specialized have said themselves they have that cutout in front of the rear wheel for weight saving, also saying having a cutout doesn't do that much for earodynamic loss

I've experienced a speed wobble going downhill.. Very scary! But happens to the best by the looks of it

Was waiting for comments on Roglic till the end 😂

Winced slightly at induced drag instead of profile drag, otherwise cracking analysis. Always pained me how hard it is to find narrow enough base bars. No idea why you'd have anything wider than legally required

💯👍

It's quite hard to get the arms forward far within the UCI dimension rules. Maybe Ganna has his seat further back? I found it felt really cramped going from CTT position to UCI.

This hole in Shiv's tt seattube might be a way to decrease the pushing effect of wind blowing from the side, especially when the bike is equipped with disc wheel plus this shiv is designed to be fast and light, so probably they saw that this hole is making bike more stable in crosswinds and ligther at the same time.

saw a comment from a world tour pro on a tt forum re aero which read (they) '' have that much gas they don't care.'' Seems the moviestar philosophy of just pedal harder is still strong.

5:30 specialized claims that it is because it’s not a aerodynamic gain and it saves weight to cut out some material

Front/rear weight distribution? Should be 50:50 ? Tyre pressure ☝️

Finally a new fucking video

Hurt me plenty

Specialised did the same thing in Rio where the bikes were labelled Specialized not S-Works. My hypothesis is that the viewership of the olympics aren’t cyclists (on average) and don’t know what SWorks is so they’re better off labelling the bikes as Specialized for brand recognition. Just my hypothesis.

You didn't talk about Roglic set up?! wtf

Curious, is it possible to compete in this event without TT bike? Just being curious.

Fastest man with IBS... Brilliant

The POC helmet, from what I have researched, favors someone who doesn't move their head around. Apparently, the second you dip down, or aren't perfectly in that position where the helmet is downright fast, you take quite a hit. I am quite sure someone with far more time and resources than me tested this and they are wearing the right helmet for their body and conditions. I think there is a movement towards minimizing the aero penalties vs going as fast as possible with the right helmet, because no matter what, the body isn't perfect.

Dammit. Now I have to go and find out how many oversized jockey wheels were actually in the top ten...

Had a conversation with Dennis's coach last year about the POC helmet. They have tested it and it was significantly slower. Guarantee you that Dennis has tested every piece of equipment and position. I believe the POC Tempor is faster for maybe 20% of riders, but can offer notable gains for those for whom it works.

The last one was damning. Lmao

I wonder how many people get the Y250 vortex reference :D

The Shiv has that cut out to fit the triathlon rear faring, non-sense to compromise one discipline for another IMO

The aero elephant in the room are rider numbers. You want to integrate timing chip (ok) but the idiotic numbers are all flappy or in special pockets. In regular WT road events it’s even more ridiculous, especially after crashes. Same with track & field, by the way. We have developed amazing aerodynamic skinsuit materials and designs but are still beholden to the ancient pinned number…

the "oversized jockey wheels" bit hurt my feelings :-) I love my ceramicspeed, but yes... probably just expensive bling really loved the analysis and insights

Damn, i hoped i was the fastest guy with IBS 😂😂😂

no bike specialist here, but usually its a bad idea to integrate anything that transmits radio signals in carbon

Smaller frames are not more aerodynamic then larger frames (Always test bike with rider!). The developers of the Dutch track bike came to that conclusion. Watch the Dutch track riders and probably their frame size is bigger than their competitors.

Is there any rationale for the idiotic UCI geometry rules?

Surely the drag from the timing chip is next to nothing

Why don't they all use TRI spokes? Surely they are much faster
