Cycling Track Men's Omnium Flying Lap 250m Time Trial - Full Replay -- London 2012 Olympic Games

[@safarektal8380]

What is crazy is that these omnium guys are almost as fast as the pure sprinters with thighs as big as tractor tires.

[@hircoe33]

No they’re not… Not even close! I can beat these guys over 200m by 2 seconds and I’m a 47 year amateur track cyclist…

[@ultrapista1237]

​@@hircoe33 they're doing 250m check the splits on these guys. Clancy did a 10.0 some sprinters can't even do that. I would like to see you knock 2 seconds on that

[@ultrapista1237]

10.0 as in a 10.0 flying 200.

[@TheRohBoat]

you are correct in this respect, but remember its the time between once you reached max speed and the time when you've completed your laps as the rider is given a lap to reach max speed (which is why it's called a flying lap). so i suppose it would mean using more energy to initially accelerate the bike but once you get to your target speed and cadence, then you could use less energy to overcome drag as you have more inertia.

Trying to follow the 6 year old comment thread about wheels that is just dispersed because of the old KZbin reply function that hasn’t converted to the new version

[@julioprieto8046]

Es todo un espectaculo ver estos montruos de la velocidad.

Question. Because I don't know the answer. On modern sprint bikes, the handlebars place the racer's hands well above the height of the top of the front wheel. Back in the 1970's, when I was a track sprinter, well, more of a kilo and omnium rider, the sprint bars put my hands down low, right about the level of the front wheel. It was a good position, because it gave me good leverage to pull hard on the handlebars, and a low aero position as well. I can't fault the newer position too much, however. The times are faster than I ever posted. Of course, I was riding a steel framed bike that weighed 16 pounds. And I presume a smaller gear. Also, there is a different technique to use on a 250m track, and a 333m track. A 333m track will produce a faster time, if the start line is approached optimally. I didn't see any of these rider use the same method as I did. I would sprint up to the fastest speed I could muster on the top of the banking, then at the last minute, dive hard down the track to enter the sprinter's lane maybe ten meters before the line. That makes it seem like the banking is shooting you out of a cannon! Then it's balls to the wall to the line, and hope you don't hit a sponge! A 250m doesn't offer the same advantage. When you dive down the banking to get up to max speed, you still have to go halfway down the straightaway before you hit the start line. The winner's time here would have been a decent 200m match sprint time when I was racing. I think my fastest was like a 13.3 or something like that. A very good effort by the winner.

[@safarektal8380]

What is the question?

[@canobenitez]

30 years ago the handles were below the front wheel, giving a low aeroposition and good leverage, nowadays it is not, even in criteriums. why?

[@Alexbc1910]

Newton's Laws: The acceleration of a body is directly proportional to, and in the same direction as, the net force acting on the body, and inversely proportional to its mass. Thus, F = ma, where F is the net force acting on the object, m is the mass of the object and a is the acceleration of the object. making heavy wheels would require more strength to get the same acceleration, in other words, they would have less acceleration, since they're alrready applying their max strength.

[@stalinmao14]

why is the commentary on all these videos so soft. I cant hear a thing. makes it so bad

[@TheRohBoat]

you are completely correct. if it would help an athlete win, athletes would probably be using heavy wheels.

[@Alexbc1910]

Ye I see your point, but I still think light wheels are an advantage as there are thousands of engeneers out there working and making researches in order to make faster bikes. If heavy wheels were a good idea, they would have already thought about that.

[@TheRohBoat]

yeah, but he said flying start. if the inertia and moment of the wheel is great enough to overcome rolling resistance the friction in the bearings, newtons first law applies: inertia

[@htdtr]

I miss this format of the omnium! Much prefer racing the old format

[@Marty666able]

NICE!!!

[@BasicallyaboutBasil]

For a flying start sprint heavy wheels would be of an advantage. I challenge a wheel manufacturer to make a 10pound rear and 5 pound front for these guys to test for the flying sprints. I'm pretty sure the results would be shocking.

[@rich.trails]

Not a chance. You have to get the bike/wheels up to speed. Lighter is always better than heavier unless you are doing a coast down test or long downhill.

[@alainbellemare2168]

with 2 curves and g force ?

[@rafaelmiliangonzalez5681]

Excellent video! Can someone tell me what planet Clancy is from?

[@jowmama658]

He’s from dn

[@ghostrider612612]

they are! not full steel wheel but some are using heavy wheels to get inertia but they have to find the balance between an lightweit bike and enough inertia

[@spuddywuddywoo1310]

ghostrider612612 the wheels they are using a fully carbon

[@johnberg181]

Moser when setting his Olympic speed record, used a heavier back wheel.

[@safarektal8380]

The Great Dane!

[@davidellis2696]

Most are still high on the track when they cross the start line.

[@123huskieman]

Does anyone know what is under the third seed's helmet? I understand it's to fill the gap, but I've been trying to find the UCI legal way online with description on how. I have the same problem in tt.

[@ollie1292]

Why is Phil Liggit not commentating?

[@ToHonestDom]

What's a normal gear ratio for them?

[@123huskieman]

DudeitsDom_ 54/5

[@HN-jn3np]

Back then about 106’ (55x14 or 51x13) now it’s much bigger 120-130’ (55x12-60x12)

[@jimmyvandano9269]

why do we even need fossil fuel motors? XD

[@kenchan9123]

i wonder how much slower they would be if they have to ride clockwise around the track.

[@spuddywuddywoo1310]

Ken Chan I cycle and I have tried to ride the track backwards and it is so much harder because you are used to leaning the other way

[@antoinedonahue-laliberte9860]

someone as their power data ?

[@isaacrosenthal-cycling]

No power meters while racing on the track

[@mickaeldagobah8914]

750w motor in the GB bike 😁

[@hemantshetty123]

how much does these bike cost

[@jean-lucdupuis7052]

Hemanth Vlogs Probably more than the average brand new BMW

[@arthurmchugh5184]

4 - 6 grand depending upon the wheels

[@mickaeldagobah8914]

French look bike 16000e with mavic/corima wheels, Gbr bike is very expensive with the motor on seat tube 😜

[@vittorioprosperi1078]

Attività 8

[@frankenscience3553]

inertia is not momentum

[@jean-lucdupuis7052]

Dave T It’s the basically the opposite

[@arthurlewis9193]

It's exactly the same. Read up on relativity.

[@BradleyWhistance]

You ain't right fam. Inertia is an intrinsic property of a massive object, irrelevant of relative velocity. Momentum is dependent on relative velocity.

[@TheEulerID]

@@arthurlewis9193 No inertia and momentum are not the same thing. Momentum is a vector which is the produce of velocity (a vector) and mass (a scalar). Inertia doesn't have any units or quantity, it's a principle. That is the tendency for something with mass to continue on an inertial path unless an external force acts upon in. In Euclidean space, this is a straight line, whilst in Einstein's General Theory of Relativity, it's something called a geodesic (basically the equivalent of a straight line in curved space-time). Of course, this is strict physics definitions; common usage is another matter.

over 44 mph for 250m....yikes
