@Pablo Morales Rim brakes are not more aero. The disc brake sits in disturbed air behind the tyre, the front wheel and the spokes. The front rim brake disturbs the aerodynamics of the design of the whole bike. It makes modelling the bike to be aerodynamic less accurate and predictable and thus leads to a less aerodynamic bike. It simply disturbs the entire aerodynamics of the bike and makes it more costly to produce aerodynamic gains, because you have to go to the windtunnel more often to make sure the airflow behaves as expected. At racing speeds the yaw angles are relatively low so the spherical shape of the disc isn't as much of a problem as it might otherwise be. It is partially shielded by other things such as its own brake, forks, aforementioned tyre, wheel and spokes. This means the amount of extra drag it can create is limited. Furthermore that drag can be limited ex. by disc brake covers and/or fork flaps to manage the air around the disc. Wheel changes then. I think we've seen several times now that disc brake wheel changes do not have to be finicky. It is a matter of preparedness, intelligent design of the thru axle and possibly using an electrical device to unscrew the bolt. Your claim that lighter and more aero wheels is both partially untrue and unsubstantiated. Firstly nothing constitutes that a rim brake wheel in itself - that is when you discount the disc rotor, which you have to in this argument, because you are obviously discounting the impact of the rim brake on the frame aerodynamics - is more aerodynamic. If anything it should be less aerodynamic compared to a wheel rim designed for use with disc brakes, because there is no same restriction on the surface material, roughness or integrity. You can engineer a surface that is more aerodynamic, because it does not have to be a certain material with properties to combat braking forces and temperature. This also means you can in theory use less material in that specific area, because there is no increased load from braking forces. To go a bit backwards through your claims I can also inform you of something which you, with your fairly backwards train of thought, should know. This is that rim brakes do rub. Comfortable bikes flex more. Lighter bikes flex more, because there is less material to preserve the integrity of the components. Riding out of the saddle your rim brake can rub - most commonly on the rear wheel. That is quite costly as the rear wheel is the place at which propulsion is generated via the crank-chainring-cassette system. I'm sorry that you are too backwards to see that the industry is delivering products made for winning and meant for riding and not ment for some 19xx hardman exhibition with 2kg of tubular spares across your chest like a woman's shoulderbag, because you don't have tubeless. Discs are winning and discs are not struggling up hills as evidenced by the near entire peloton. Discs barely have to be changed, because riders barely puncture on wider, stronger(technological advancements, my man) tyres at lower pressures of also the tubeless or clincher variations, Adios, neanderthal.
Imagine Roglic being on the last climb of the day on his Cervelo CX bike with 25mm tubs and The Rim Brake Cartel swap to the front and shred away up the road on their 1100g Meilenstein's
Ahaha, rim for the win! Just one note, I think Ineos switched from Meilenstein to Princeton Carbonworks: www.cyclingnews.com/news/ineos-grenadiers-switch-to-sponsor-incorrect-princeton-carbonworks-wheels-at-tour-de-france/
Have a guess which team this year has the least frustrated and stressed mechanics. 😆. I had one of the first disc road bikes in Oz. I soon regretted it as the heavier Zipp 202's and rubbing rotors just kill off how a lighter road bike should ride.
Shit argument, cant compare one of the first disc road bikes in Oz with disc road bikes now. Its like saying Di2 is shit because your dura ace 7900 Di2 was bad. Not that I disagree with you on which is better
Pretty sure Yates rides a smaller frame than that! I read it was a 48 or 49cm. The bianchis are lovely but rim is still the lighter option vs disc on a comparable frame
I’m guessing the supply chain partner. Shimano can’t produce rim brakes at scale big enough to meet Pinarello’s order. Caused by the pandemic bike boom.
@@MarkRiddellRacing Makes a big difference at that level. You have guys starving themselves to lose an extra 1kg for a race & then the sponsors slap disc rotors on the bike 😂
@@iminc5498 correct, at that level. But the arguments over disc vs rim for us average roadies is a waste of Internet bandwidth. None of us are competing for the Yellow Jersey, so the weight doesn't mean a thing.
i was really hoping they stayed on rim brake. my riding mates all have disc and its really annoying ... no offence but all offence. Rim is better for what i do
Like every bike review these days. it's lighter,faster,aero,stiffer,better,more expensive. have we said it's better. GCN and their paid content. they arent going to say find a 2010 bike because it wont get any better.
