Rants and WTF are you talking about and Coronavirus!

[PaulInZurich]

Believe me (25 years of cycling, often 3 times in a week), if you have some power in your legs it's not so difficult to reach 70 km / h on a more than 5% downhill.

I think that the calculation about max speed is missing the rider possible pedalling (depends on max gearing and max cadence) and you would need to know the cdA of the rider. You could pick a medium cdA, but some riders are much more aero than others. For downhills in real life the limiting factors are traffic, curves, road surface, how well do you know the downhill, is it windy etc. On a fast enough downhill even an almost invisible bump in the road can throw you off. I have a favorite downhill here in the ZRH area, I see the entire road when I am at the top, it is fairly straight and I have been down that road hundreds of times. I wouldn't bomb down a road I don't know, since over the years I have left my share of skin on the road. Road rash is not fun.

You know when "whataboutism" or even an analogy is needed to defend a point? When the point doesn't have it's own merit to stand. My point is: can we really trust the scientists or the companies that they work for which were repeatedly convicted and fined billions of dollars for repeated deceptions? We don't need any analogy to conclude that the resounding correct answer is "No! We cannot trust them". Period. Case closed.

If you still want to investigate that conclusion, go ahead do your own research. Here are some starting points (please watch them with your clam open mind, instead of being angry that Gino is trying to tell you something that you think you are right and he's wrong):

You do realize that Pfizers vaccine was developed entirely by BionTech scientists right? Pfizer had no role in development. And what of Moderna?

You can call me whatever names you want, but none of that will change the hard facts.

Even if your second degree of association was to be given any consideration, you forgot to consider that BionTech developed the vaccine entirely on it's own. Pfizer was only brought on to help process production, clinical trial logistics, legal, and distribution. Plus there's Moderna. So there's all that.

As for superman, when he decided to write the "I'm a pro cyclist with 3 months of practice in a year" chapter of his fantasized autobiography on this board, he first claimed that he was very fast going downhill at 60 km / h. Then suddenly he skipped to 70 km / h. But that's someone who thinks that having a sub 9 kg bike is something to brag about and that Scott KTM is a model of bike.

For sure when you're 90-100 kg. But for a 70 kg man, the physics doesn't quite work out without the bike taking air.

... with my confidence ...

Being delusional is completely different than having confidence, old man. You still climb a 150 W only, plenty of women with more power.

It wasn't even whataboutism but a valid analogy that demonstrated the fallacy of his reasoning.

Translation: he crashed the car.

Yes I was the driver so I m responsible and fortunately no other car, only me, but when I needed 1 year to prove to Audi engine had a problem when they didn't find and they changed under guaranty and after no more problem, today I went to see works, explaining them again balance problem on rear because of quattro. After works, expert will test car, I don t care when driving like a papy, Audi will test, I don t care, I told them I will test and take their testing guy with me and they know what I mean. I would not drive Audi quattro to be a Swiss snail, I would buy Dacia, I laugh through Switzerland seeing powerful cars blocked in first gear. Downhill on bicycle at 70 km / h is much more impressive than 250 in a car. But you have to experience both to know.

A 65 kg, 1.65 m high, rectangular shaped object going down a 20% (12 degree) gradient at 1700 m altitude would reach a terminal velocity once he gains enough speed where the drag force cancels out acceleration due to gravity. That speed would be a out 66 km / HR, and that's ignoring forces like friction of tires and gears which, by logic, would decreased that terminal velocity even more. His claim of the riding down a 20% grade mountain, helmetless at 70 km / HR is first a dumb as shit thing to do, but more importantly, impossible as determined by the laws of physics. But maybe Sirioja lives under a different set of physical laws.

LOL, nobody is able to climb Zoncolan at 20 km / h, unless you mean one short section where it's flat. Pros like Pinot or Woods climb it at 14 km / h. You are climbing at 6 km / h, as it came out based on your own inflated claim. Soon you will say that you climb it at 100 km / h.

Learn to read when I wrote with my confidence and now relax for climbing even in Zoncolan or Mortirolo or Loze when I usually climbed forcing, so I look forward next Summer to climb faster, even I want to return to Ventoux with car repaired, when I'm so much faster now than when I started in my 30's on 2003 and I will have same perfect bicycle which would be able to climb at 20 km / h with somebody able to turn enough legs but no professional even with engine in electric gears and all products they take is able. I climbed at 7,5 average the 10,5 kms Ovaro up to Zoncolan with 3 very wet and dark tunnels on top and controlling my effort, 8,5 average and easy in Loze slaloming among gravels on track when I m sure they cleaned for tour de France, but just try to reach the top of them if You are able when we are friends with my bicycle for this and faster in the steep than many expensive bicycle.

[Mursenary]

I'm less than 65 kgs, better to climb, but you never been on a bicycle and you don't know anything about cinetic energy when downhill on 20% steep, you are very fast and easily faster than 70 km / h and I'm not good downhill on bicycle because not heavy enough, don't take too much risk and usually a bit cold in high mountains. You and ZH should really jump on a bicycle to really know more than on internet. Professionals reach 90/100 km / h on less impressive steep.

Silly old man. I've road across Florida over 2 weeks and used to bike up Sierra Nevadas of California.

Being less than 65 kg at the same height would actually even lower your terminal speed even more. I don't care how fast you are, impossible to be faster than physics, dummy.

[PaulInZurich]

I'm less than 65 kgs, better to climb.

Still only 150 W, there are plenty of women with more power. If weight would be the only thing that matter, 5 year old children would be the best at cycling uphill.

Yes, whataboutism. But in this case it serves a valid criticism. The choice would be to not serve in the military. I don't support those people. I don't think in political dichotomies.

[Gino02]

Cherry picking the evidence to support his self-centered anger and paranoid. Not to mention that the Pfizer vaccine has been monitored and evaluated by entities outside their corporate structure. And they are far from the only vaccine manufacturers.

Bottom line is that twerps like Gino have been kicking, screaming and crying from day one, in a hooker forum because his mongering life has been disrupted. First he was against the restrictions. Since these were demonstrated as useful in saving lives, now the cause is anti-vaxxers. Gino just don't get a vaccine, quit crying and go buy some pussy. There's a lot for sale out there, and all over the world.

No, the choice would be to serve in military, expose and kick out the bad commder-in-chiefs.

Glad you don't think in political dichotomies, now just start thinking logically.

Well, I agree you don't need a helmet, I mean you don't have any brain worth while protecting.
