"Pumping up tires as high possible!" lmao. See how the so-called experts don't know their behinds from their elbows... Deformation? Uh, you WANT a level of deformity, to 'push' the rubber into the road surface. This is called Vertical Load or the Coefficient of Friction. AKA- Traction. Tires inflated to high pressures reduce vertical load. And when Lateral Load increase, traction is either greatly reduced or broken. Resulting in a crash.
Smaller area of contact results in a higher pressure and HIGHER traction. Unless u a riding over a dirt. Cyclists tends to pump their tires up to the limit - that is the fact.
#LMFAO Dude, you are SO seriously mistaken and under-educated about pressures, contact patches and traction (the coefficient of friction) and in fact your comment is so far off base, it borders on ignorance. Now I will school you on the matter.
Higher pressures result in LESS contact patch on ANYTHING but smooth glass-like surfaces (Perhaps a velodrome would be the only place high pressures would be beneficial) First and foremost, on a standard road bike, the tyres are the only 'form' of suspension/dampening. Perhaps you do not grasp this concept. High pressures reduce traction via less time of contact with the road surfaces. High pressure tyres will bounce off irregularities, bumps and cracked pavement thereby reducing both speed AND control. Your absolutely naive, silly comment of 'that is a fact' is so laughable it's both funny and sad. I highly suggest you educate yourself on the matter. starting with Jan Heine's many years of in-depth research on the subject. In the meantime, you should keep your gob shut until understand and know the real facts son.
In modern bicycle the rim also partially acts as a suspension - it is not 100% rigid. And overall it is very complex process. Hi pressure not always results in crazy bouncing. Yet i may be wrong about *highest* pressure...
Lmfao so what is the physics of Cycling and racing on a 14 kg bike? GTFO of here with your "I need a 6 kg bike because my legs look like an 80 year old" crap. If you cant have a race on a 10 kg bike you should immediately GTFO out of cycling.

You can just see the presenter smiling and not understanding any of the technical stuff he's explaining. xD
It's not just the presenter! :-D
hey there
the best way to understand is to listen
if the "presenter" who you call so keeps speaking then he would not be able to listen

Too many generalisations, if not outright mistakes... i gave up at 3 mins

You would be what the Italians call Stunod... #ufb #rollingeyes
