The marketing team circle jerk that resulted in the claim that the wheel-frame gap is advantageous is truly astounding.

Who the fuck , I mean I less you're Rossi on a Yamaha or Marquez on a Honda, why the fuck would you want down force, but yea I agree hahaha, money is on specialized
The market for these is super limited and the use cases even fewer. Only dumbasses with too much money actually buy these and then don't even ride it because they aren't actually athletic enough for the low position. Anyone who actually rides bikes wants to be able to replace their stem when they feel their back needs a break. They are also horrible to sell because of the fitting problems with integrated cockpit (to replace one is hours of work) and how Bianchi doesn't supply a tall enough seat post to begin with because inserting a longer one too violently into the frame would damage the frame. To get a taller one you have to sign a waiver and send it to Italy before they send you your seat post.
I think if you actually need a new (aero) roadbike certain options do make sense. Canyon, Scott and Simplon for example are more on the affordable side in comparison to Specialized, Bianchi and Pinarello. Also you partly do have options here to personalize the cockpit (like with the Pride II). While everyone has to answer how much you want to spend on a bike for themselves, in my opinion I agree that there is no advantage with those ridiculously priced bikes more than the brand name on the frame.
Your maths at the end made me think back to when road discs first took hold, and the tech editor at CN said that there may be 5 or 6 W of drag from disc brakes...but that it was inconsequential.

$14000 gets you Honda CBR1000RR or Yamaha R1. Eff performance cycling with their microscopical gains for the most amount of money imaginable. I work in a bike shop and even with all the wealth of my experience I can't get why even modest bicycles are so damn expensive.

It makes zero sense.

Everyone deserves a 2nd chance but not 3rd,4th,or every review he has posted since.Meanwhile,I am off to buy Italian artisan stabilisers for my 3 year old but only if it costs 299 euros and saves 3watts...after all that's what's a self respecting 3 year old would find important
Wing slats (front of wing) work in conjunction with the wing flaps (rear of wing) increasing the cord thus the pressure delta between upper and lower surfaces thus increased lift for the velocity sorry to be pedant.
As an ordinary (old) rider my average speed is 30kph. I have to ask why would I want to save 30s over a 45km ride. What vital task to myself or humanity would I perform after saving this vast amount of time. The simple fact is that by doing nothing more than riding on the limit for the 45km I could 'save' more than 30s. So is the point of these marginal gains is to ride with the same effort and spend less time riding your bike? If that's the case just ride for 40km or not at all.
@@vbedelev I would agree if this type of bike was marketed as 'race only' special. But they are marketed to ordinary riders. You won't find the words 'race' or 'kom' in any of the marketing blurb because that would simply put off the average person.
@@hallisoft1926 Since there is Strava, no more "ordinary" bikers. I doubt, "ordinary" bikers to can ride with avg. speed of 30 km/h, unless they live in flat place or in place, where there is no front or cross winds, or.....30 km/h avg. speed is only for distance up to 5 km
The "generous clearance" as described in their gibberish I believe is referring to side clearance between the wheel/tire and the fork legs, which I can believe. The larger gap to the down tube is simply a negative consequence of the larger range of tire widths road bikes are expected to be able to use. It's not uncommon for something to be lost between designers/engineers and the marketing department.
And while we're at it, why is the radial clearance different for front and rear? And why is the rear tighter? If anything, it's the front wheel that should have narrower clearance.
@@AG-el6vt the rear clearance is tighter because it's triangulated and therefore structurally stiffer. Nothing is going to push that rear tire into the seat tube. Forks flex fore-aft in regular use though
Well, you don't se a lot of extra edges and holes and stuff in sail planes. And there is a good reason for that: Extra edges and holes add drag. And you don't want that. But I guess it works as marketing in the bike industry since the byers usually don't have a clue (exept Hambini fans, but I guess we are not in the target group for this bike anyway).
For what it's worth, if they weren't scientifically illiterate and estimated how far 250Wh (and not W/h) can take you, it would have been an interesting metric. As a long-distance rider I'd be somewhat more interested in knowing how much further I can get for a given number of Wh or kJ at a given average speed (or how many total Wh or kJ I saved over a given distance) than knowing that I "saved" xyz watts of power. Sure I could do the maths myself, but it's a more relevant metric so far as I'm concerned.
@@alavroff01 well look at Hambini, he is 5 altogether and already knows more about engineering and physics than all the cheeky wankers from every single bike channel and publication put together. Not to mention his pen is working, which I don't really think it's the case for the Bianchi bloke who wrote that 250W/h bullshit.
We're all waiting for the Hambini 1.0 UltraBike. But first he has to evolve a bit - the bottom bracket is only a small part that no one gets to see anyway. lol
@@wjs1 I do not like the bike in the review, but have no doubt $10k plus bikes are better than $5k ones, because I know $5k ones are waaaaaaaay better that $500 ones.
My first car was an Italian Alfa 33 QV S..... everyone warned me up front but it was an awesome car, never let me down. What I want to say..... Italians can make mistakes too, having you ending up with an actual good functioning product. It's highly unlikely and I wouldn't gamble 14k for it.... (my car was 7000 gulden, 3k euro) but you never know, you might be lucky!
The 1% saving is because the air deflectors actually suck in air and eject it out the rear. It can be seen at 7:38 that instead of something resembling wind tunnel laminar flow air the air defectors actually suck in air before it even gets to them.
@Hambini Unfortunately there is a mistake in your Hambini does Math slide. In your calculation wind resistance would scale linearly with the energy: going twice as fast/slow would require double/half the watts. But wind resistance scales with the third power regarding the energy. The right way to calculate the savings would be (40*3600/(3600-45)/40)^3*250=259.6. So you actually save 10 watts according to their claims.
259.6 x 3555 is 922878. So you would be putting in more energy into the system. The way I did it. I fixed the time and basically equated it to watt hours or joules
Good point Hauke. The other thing that is missed by Hambini is that the aero / power gains are rarely mutually exclusive and this is the difference between a performance cyclist and an armchair enthusist engineer on RUclips who tears everything to pieces but could probably struggle to ride around the block at 40km/h regardless of whether he was using one of his own bottom brackets or not LOL. Gains are gains and if you can have this bike AND tuck your head in AND wrap your bartape properly etc etc then those all add up. You don't have to choose just one and be done with it.
Imagine the first crash on the bike and you squish the "air deflector units" on the headtube - what do you do, nip down to the local vacuum cleaner store and by a hoover attachment?
The air intakes on the front look like they are taken straight from one of those weird renders of 'futuristic' bikes, cut out of cardboard and put on the bike by someone that looked at an F1 car and thought he did 'an aerodynamics.'
Its telling everyone about it after riding in the group/club for 8 miles and then sitting in a cafe eating bacon butties and drinking coffee,because none of the serious riders wouldn't pay that 👍
Invest in a coach and a good bike fit and you'll get way faster. If you already have access to these and still feel the need to buy the bike, invest in a therapist in order to work on you self-confidence. You need it.
Correct me if I am wrong, but the 40kph/watts numbers must be without a rider(nice trick). In my experience 40kph takes about 325 watts for and average sized rider.
Hey mate, They (engineering tram) may have allowed more clearance between down tube and front tyre to alleviate possible clash point. How much flex through the frame if say a 100kg bloke decending a steep hill applying brakes. Just a thought?
I have just checked, out of curiosity, your video is at 2.2k likes/42595 views right now, whereas the factory Bianchi video "Introducing - The New Oltre" has 647 likes/27696 views.
One has to admire front end adjustability and ease of use the most. Looks like you can adjust... Nothing? And the thought of traveling with it, putting it in a bike box, gives me anxiety. And it doesn't even look nice.
On the plus side, more previous gen Oltres on the market when the dentists upgrade :) Also it is just me or do the front nostrils look really badly finished? Like someone literally cut up a sheet of plastic with scissors and glued it to the front? I say this as the owner of a 2021 Bianchi Aria :)
It would be interesting to have a friend who has a 3-D printer to build a plastic "filler" for the area between the front tire and the frame. You would have to make a couple to determine exactly how thick you could go before the tire rubs. Add a little extra space, just in case. Then, ride about 85% effort and spill out the speed gains! Using double-sided sticky tape, it could be removed and replaced until a final size is found. Also could be done with any other deep frame cut bike. Homework for someone....
I did this exact homework on other areas of bike. If you are on Strava. Send me a follow request on "Knight of Faith" I employed a mini air deflector that is used in for car antenna cover for the area you are talking about. Only afterwards you can build something which you are mentioning as we need to close out the end where the antenna cover will come handy. Otherwise there will be two different types of airflow that would create drag
@@colecoleman1499 Honestly, looking away from all the marketing material, this may be quite astute advice. See my other comment under this video about a comparison done between a modern aero bike and a steel bike from 2003 - which is not at all enough to conclude from, but which does show some interesting results
I have a few questions and comments. 1) I do get fed up with marketeers (RUclipsrs) saying how much 'faster' a bike is and then quoting power figures - when I trained as an engineer speed was measured in distance per unit time and NOT in Watts. 2) relation point one above I know why they do this. The (aerodynamic) power required goes up with the cube of the speed and therefore exaggerates any difference. 3) in this case the power difference does approximately equate to speed difference as the Delta is quite small. 4) I suspect the 43 seconds quoted relates to some ideal circumstances, and maybe not to the real world. 5) If (a big if) the bike does really give a 43s advantage over 1-hour ride, I'm sure many racers will take that as a big win. 6) if you're interested I did some extensive real-world testing of the speed difference between a race bike and a touring bike (ruclips.net/video/YXvp-9xecUc/видео.html). Given the very different types of bike that differences weren't that big.
I totally agree, the wankateering departments put info out there that is borderline misleading but deliberately insufficient to make a full comparison. This particular bike was claimed to be 30% better in crosswinds than the rest. How the F is that even measured.
I wonder when the first bike is going to be released that claims to provide a lift or negative downforce to cycle faster uphill thanks to aero features
it's funny how bike companies act as if they tried to convince customers that we dealing with fighter plane cruising at 1600 km/h and not simple bicycle with dentist or lawyer on it cruising at 30 km/h
Hey, why didn’t they get their front scoop thing to lock the air along the top tube, from what you said - might that actually have done something useful?
It's just a joke, there is nothing to gain by tubing the flow, because then you are faced with the drag outside of the tube, too. So it is just decoration and does nothing but move the problem a few mm laterally, at best; probably it makes it even worse by introducing a point with different air speeds, Hambini explained.
I don’t really see how anything substantially aerodynamic can be incorporated between front wheel and frame, since the front wheel is hardly ever kept perfectly inline with the frame.
As an Italian I feel deeply offended that you picked something that is STILL STANDING as an example of fine engineering. The ponte Morandi would have been a better pick :P
Last year, Norwegian cycling magazine, Landevei, tested and compared two bikes: a hyper-modern full-on aero bike (Trek Madone 2019, world championship bike of Mads Pedersen) and a steel bike from 2003 (with new bearings and tires), and found that the old steel bike was not slower (in fact it seemed to be faster..) than the new top aero bike both uphill and on the flats! There are probably a few limitations in their tests, which they acknowledge, but the results are nevertheless interesting, to put it mildly..

Doesn't surprise me. To be honest, most of the guys I see riding these bikes on the road are the 'all the gear, no idea' types who simply want to have the latest shizzle. A race team is one thing, but in real world usage, among traffic and dodging pot-holes etc, all these gains won't really amount to much at all.
I was in Harrowgate for the 2019 worlds. I hold the firm opinion that mads won because he was a nordic citizen and was accustomed to the horrendous conditins we had those two weeks.
THANKS! Warms my heart to hear this as I am still riding a quite 'dated', maybe even 'retro' or "ancient" to some at this point, circa 2000 Merlin Road with Record 10 gruppo. NEVER any problems/creaking from the threaded and TRUE bottom bracket, no rubbing from the rim brakes, no slipping aero seat post, and no plastic to stress crack when I hit an unseen crater on the roads around here. The best part is that I did not have to go into debt for the rest of my life by buying a $15K to $25K USD road bike to ride, since it did not cost all that much to build back in '99/2000, and that cost was 'amortized' over the last 22 years. 😊👍
They will CRACK the top tubes of half of these crunchy carbon, 'plastic fantastic' frames nowadays if they do that often enough, on rough enough downhills.
If they put its 1.2% faster than our last model they wouldn't sell many. But if they state its our fastest bike ever made. People will be handing over their cash in buckets.
Waiting for some video commenting on Factor bikes, had two of them and wonder if I did something good in my life choosing them from engineer perspective.
I am going to get some red party cups, cut off the bottom, and tack them to the head tube of my bike. I bet my design will have better airflow. Plus it will look like I have two turbofan engines! SWOOOOOSH!
I learn something new every time I watch this channel. Bloody love it. What I’m really interested is there a bike that meets your standards? If so, could you do a video on it? Think I’ll be keeping hold of my 13 yr old road bike for the time being.

They're cycling at 250W = P
assuming all the drag is aerodynamic, and CdA does not change with speed
P= 0.5 x speed cubed x air density x CdA
with rearrangement and substitution we can simplify this to a combined drag co-efficient
v^3=D
Case 1, they cycle 40km in 3600 seconds.
Their speed is 11.11111m/s (they've got a pretty small CdA for a non TT bike)
So D(1) = 1372
Case 2, they ride a slipperier bike, so complete the 40km in 3555 seconds
Their speed is now 11.25m/s
so D(2) = 1424
The %age difference between these drag co-efficients is 3.8%
3.8% of 250W = 9.6W

Wing slats (front of wing) work in conjunction with the wing flaps (rear of wing) increasing the cord thus the pressure delta between upper and lower surfaces thus increased lift for the velocity sorry to be pedant.

I think the air deflector provides downforce to keep the Pirellis in the right temperature window.
As an ordinary (old) rider my average speed is 30kph. I have to ask why would I want to save 30s over a 45km ride. What vital task to myself or humanity would I perform after saving this vast amount of time. The simple fact is that by doing nothing more than riding on the limit for the 45km I could 'save' more than 30s. So is the point of these marginal gains is to ride with the same effort and spend less time riding your bike? If that's the case just ride for 40km or not at all.
It is not about the saving time ! It is about of winning the race, or getting the KOM on any segment ;)
@@vbedelev I would agree if this type of bike was marketed as 'race only' special. But they are marketed to ordinary riders. You won't find the words 'race' or 'kom' in any of the marketing blurb because that would simply put off the average person.

It looks like a Cervelo and the frame mold had a child 😆
More like it looks like Cervelo and Marin (the stealth tube era, 2008-2010) had an one night stand and conceived a child
The "generous clearance" as described in their gibberish I believe is referring to side clearance between the wheel/tire and the fork legs, which I can believe. The larger gap to the down tube is simply a negative consequence of the larger range of tire widths road bikes are expected to be able to use. It's not uncommon for something to be lost between designers/engineers and the marketing department.
And while we're at it, why is the radial clearance different for front and rear? And why is the rear tighter? If anything, it's the front wheel that should have narrower clearance.
@@AG-el6vt the rear clearance is tighter because it's triangulated and therefore structurally stiffer. Nothing is going to push that rear tire into the seat tube. Forks flex fore-aft in regular use though
Funny that the SL7 has a cutout to leave a massive gap on the back wheel instead...
The big question is can the air intakes be used to open a beer?
So,what about the oltro comp 105? With regular handlebar? Is it worth it? It is like 5-6 thousands euros.
How does it compare to the pro and rc?
Well, you don't se a lot of extra edges and holes and stuff in sail planes. And there is a good reason for that: Extra edges and holes add drag. And you don't want that. But I guess it works as marketing in the bike industry since the byers usually don't have a clue (exept Hambini fans, but I guess we are not in the target group for this bike anyway).
They legit wrote bs about how fast it goes when putting "250W/h" on their website 🤣
For what it's worth, if they weren't scientifically illiterate and estimated how far 250Wh (and not W/h) can take you, it would have been an interesting metric. As a long-distance rider I'd be somewhat more interested in knowing how much further I can get for a given number of Wh or kJ at a given average speed (or how many total Wh or kJ I saved over a given distance) than knowing that I "saved" xyz watts of power. Sure I could do the maths myself, but it's a more relevant metric so far as I'm concerned.
@@11robotics They did write W/h which would be power divided by time and not W.h (Wh) which is energy (1 Wh being 3600 J)
@@alavroff01 yes so as I've said, they are scientifically illiterate.

Dear @Hambini, is there a top end bicycle deserving an all round positive review? Like a Dogma F, a C68 or a Ridley Helium, etc.
are those things on the bars for mounting the garmin?
My first car was an Italian Alfa 33 QV S..... everyone warned me up front but it was an awesome car, never let me down. What I want to say..... Italians can make mistakes too, having you ending up with an actual good functioning product. It's highly unlikely and I wouldn't gamble 14k for it.... (my car was 7000 gulden, 3k euro) but you never know, you might be lucky!
Glad you enjoyed your Alfa, so many fell apart with engine still strong but in a carcase of rust..
is the 14 , 000 in Japanese yen or Thai Bhat?
The 1% saving is because the air deflectors actually suck in air and eject it out the rear. It can be seen at 7:38 that instead of something resembling wind tunnel laminar flow air the air defectors actually suck in air before it even gets to them.
@Hambini Unfortunately there is a mistake in your Hambini does Math slide. In your calculation wind resistance would scale linearly with the energy: going twice as fast/slow would require double/half the watts. But wind resistance scales with the third power regarding the energy. The right way to calculate the savings would be (40*3600/(3600-45)/40)^3*250=259.6. So you actually save 10 watts according to their claims.
This also fits their 17 watts@50kph aero claim if you calculate it down to 40kph: (40/50)^3*17=9
259.6 x 3555 is 922878. So you would be putting in more energy into the system. The way I did it. I fixed the time and basically equated it to watt hours or joules
Good point Hauke. The other thing that is missed by Hambini is that the aero / power gains are rarely mutually exclusive and this is the difference between a performance cyclist and an armchair enthusist engineer on RUclips who tears everything to pieces but could probably struggle to ride around the block at 40km/h regardless of whether he was using one of his own bottom brackets or not LOL. Gains are gains and if you can have this bike AND tuck your head in AND wrap your bartape properly etc etc then those all add up. You don't have to choose just one and be done with it.
$14000 would be better spent on a good Hairdresser. Yet again great vlog 👍👍
I'd like to have the $14,000 hairdresser! It'd probably raise this 63 year olds FTP by 100 watts! Better than Zwift no doubt!
Imagine the first crash on the bike and you squish the "air deflector units" on the headtube - what do you do, nip down to the local vacuum cleaner store and by a hoover attachment?
That's the cooling intake for the hidden motor! 😆
the introduction is impressive! 100% endorsement!
The air intakes on the front look like they are taken straight from one of those weird renders of 'futuristic' bikes, cut out of cardboard and put on the bike by someone that looked at an F1 car and thought he did 'an aerodynamics.'
The hole in the handle bars is a pen is working holder 😃🎯
I just don’t see how 14k for a bike makes the experience of riding that much better
Its telling everyone about it after riding in the group/club for 8 miles and then sitting in a cafe eating bacon butties and drinking coffee,because none of the serious riders wouldn't pay that 👍
What spec/cost bike would you be comparing it to?
What bike do you ride?
Invest in a coach and a good bike fit and you'll get way faster.
If you already have access to these and still feel the need to buy the bike, invest in a therapist in order to work on you self-confidence. You need it.
Is the large tire clearance at the front wheel necessary because the fork flexes back and forth during normal riding?
I'd not want to ride a bike that flexes this much
Is the fork made of pure resin or do they actually put any carbon fibers in it?
You're correct that power (watts) * time is energy (joules). The SI units for power are Joules/second.
Correct me if I am wrong, but the 40kph/watts numbers must be without a rider(nice trick). In my experience 40kph takes about 325 watts for and average sized rider.
nope; 212 w over a 100 mile TT would have me at 25 mph (40 kmh)

I feel like this is what happens when the design team goes for a boozy lunch then designs a bike 😂.
Yep, gotta have that wine to get some inspiration..lol
@@Reanimator999 I suspect they skipped straight to the Grappa on this one.
So concluding: space technology of the future, great masterpiece of engeenering.
One has to admire front end adjustability and ease of use the most. Looks like you can adjust... Nothing? And the thought of traveling with it, putting it in a bike box, gives me anxiety. And it doesn't even look nice.
On the plus side, more previous gen Oltres on the market when the dentists upgrade :) Also it is just me or do the front nostrils look really badly finished? Like someone literally cut up a sheet of plastic with scissors and glued it to the front? I say this as the owner of a 2021 Bianchi Aria :)
It would be interesting to have a friend who has a 3-D printer to build a plastic "filler" for the area between the front tire and the frame. You would have to make a couple to determine exactly how thick you could go before the tire rubs. Add a little extra space, just in case. Then, ride about 85% effort and spill out the speed gains! Using double-sided sticky tape, it could be removed and replaced until a final size is found. Also could be done with any other deep frame cut bike. Homework for someone....
I did this exact homework on other areas of bike. If you are on Strava. Send me a follow request on "Knight of Faith" I employed a mini air deflector that is used in for car antenna cover for the area you are talking about. Only afterwards you can build something which you are mentioning as we need to close out the end where the antenna cover will come handy. Otherwise there will be two different types of airflow that would create drag
Faster than your bike, Hambini
Great... explanation. So, what would you concider to be a good aero-road bike?
Anything with a flat narrow handlebar and 23 m width external wheels with tires of same width
@@colecoleman1499 Honestly, looking away from all the marketing material, this may be quite astute advice. See my other comment under this video about a comparison done between a modern aero bike and a steel bike from 2003 - which is not at all enough to conclude from, but which does show some interesting results
Could u do a review on Jamis renegade carbon bicycles?
A speed hole in the handle bar! Wow!
Well crap! Glad I watched this because I am (was) seriously considering this bike in the next month or 2.
I have a few questions and comments.
1) I do get fed up with marketeers (RUclipsrs) saying how much 'faster' a bike is and then quoting power figures - when I trained as an engineer speed was measured in distance per unit time and NOT in Watts.
2) relation point one above I know why they do this. The (aerodynamic) power required goes up with the cube of the speed and therefore exaggerates any difference.
3) in this case the power difference does approximately equate to speed difference as the Delta is quite small.
4) I suspect the 43 seconds quoted relates to some ideal circumstances, and maybe not to the real world.
5) If (a big if) the bike does really give a 43s advantage over 1-hour ride, I'm sure many racers will take that as a big win.
6) if you're interested I did some extensive real-world testing of the speed difference between a race bike and a touring bike (ruclips.net/video/YXvp-9xecUc/видео.html). Given the very different types of bike that differences weren't that big.
I totally agree, the wankateering departments put info out there that is borderline misleading but deliberately insufficient to make a full comparison. This particular bike was claimed to be 30% better in crosswinds than the rest. How the F is that even measured.
Just now I learned that Bianchi’s main factory is located in a town in Italy named China. Wow, just wow.
I wonder when the first bike is going to be released that claims to provide a lift or negative downforce to cycle faster uphill thanks to aero features
it's funny how bike companies act as if they tried to convince customers that we dealing with fighter plane cruising at 1600 km/h and not simple bicycle with dentist or lawyer on it cruising at 30 km/h
Obese dentists and barristers can ride @30KPH?!? 🤣
Hey, why didn’t they get their front scoop thing to lock the air along the top tube, from what you said - might that actually have done something useful?
It's just a joke, there is nothing to gain by tubing the flow, because then you are faced with the drag outside of the tube, too. So it is just decoration and does nothing but move the problem a few mm laterally, at best; probably it makes it even worse by introducing a point with different air speeds, Hambini explained.
That’s why I ride new old stock and steel frames, I reject this new age marketing nonsense.
Pretty sure the bike industry (with the exception of power meter manufacturers) have no idea what a confidence interval is.
I don’t really see how anything substantially aerodynamic can be incorporated between front wheel and frame, since the front wheel is hardly ever kept perfectly inline with the frame.
Just watch them go back to tiny front wheels to accomodate all the aero on the frame, like a superbike
@@patrykK1028 Maybe, if they can bribe the UCI officials with enough coin. 😉
First thing is the cockpit. Stem is in the air. The hoods you could only argue is to protect your hands.
Thank you
As an Italian I feel deeply offended that you picked something that is STILL STANDING as an example of fine engineering. The ponte Morandi would have been a better pick :P
Last year, Norwegian cycling magazine, Landevei, tested and compared two bikes: a hyper-modern full-on aero bike (Trek Madone 2019, world championship bike of Mads Pedersen) and a steel bike from 2003 (with new bearings and tires), and found that the old steel bike was not slower (in fact it seemed to be faster..) than the new top aero bike both uphill and on the flats! There are probably a few limitations in their tests, which they acknowledge, but the results are nevertheless interesting, to put it mildly..

Doesn't surprise me. To be honest, most of the guys I see riding these bikes on the road are the 'all the gear, no idea' types who simply want to have the latest shizzle. A race team is one thing, but in real world usage, among traffic and dodging pot-holes etc, all these gains won't really amount to much at all.
Very interesting thanks for sharing
I was in Harrowgate for the 2019 worlds. I hold the firm opinion that mads won because he was a nordic citizen and was accustomed to the horrendous conditins we had those two weeks.

Warms my heart to hear this as I am still riding a quite 'dated', maybe even 'retro' or "ancient" to some at this point, circa 2000 Merlin Road with Record 10 gruppo.
NEVER any problems/creaking from the threaded and TRUE bottom bracket, no rubbing from the rim brakes, no slipping aero seat post, and no plastic to stress crack when I hit an unseen crater on the roads around here.
The best part is that I did not have to go into debt for the rest of my life by buying a $15K to $25K USD road bike to ride, since it did not cost all that much to build back in '99/2000, and that cost was 'amortized' over the last 22 years. 😊👍
Where's Dave Arthur's road test?
Being scripted by the bianchi pr department right now
With so many people into sitting on the top tube trying to get aero on a descent, the engineers aimed to make it more comfortable to super tuck.
They will CRACK the top tubes of half of these crunchy carbon, 'plastic fantastic' frames nowadays if they do that often enough, on rough enough downhills.
If they put its 1.2% faster than our last model they wouldn't sell many. But if they state its our fastest bike ever made. People will be handing over their cash in buckets.
Did you ever do a video about Colnago?
the lever angle suggests Bianchi employees are compensating for something
Hi Hambini are chainguards or disc shrouds UCI banned and what would be the effect Ive heard they would improve aero
For discs, yes
And cause too much heat to be worthwhile.
Putting on some 15$ aero socks saves you twice as many watts, its just ridiculous..
Waiting for some video commenting on Factor bikes, had two of them and wonder if I did something good in my life choosing them from engineer perspective.
Oh I thought those air deflectors were there to cool your "pen is."
I am going to get some red party cups, cut off the bottom, and tack them to the head tube of my bike. I bet my design will have better airflow. Plus it will look like I have two turbofan engines! SWOOOOOSH!
