@Aramintai I will be honest with you, I don't know which will be best for me. Those I have on the bike are simply aliminium, fairly light, not aero and work with clinchers and discs. As a year round rider the last part was key and I went for the best overall bike for the cash. Next time I will do the same so as you say it probably won't have these wheels on it but maybe something inspired by these and the others you mention.

@@andrewschietzsch5398 your right. I hadn't pre conditioned my statement but I was implying that most of us are already using decent carbon rims so I dont see the advancement made here truly revolutionary or worth the hype/cost.

What delights me the most is that I can actually believe these wheels are better. Thanks GCN for a down to earth explanation and review. It's all too common that new products are marketed with fancy buzzwords and unintelligible benefits.
Love cylcling videos just what I need to get it going the blood I love it. I always watch these before I go out and get my body moving. I always watch one of these, and then put up my heavy playlist like Delta Parole, Three Days Grace, System and then I just go haaaaard!!!! Tactic hasnt let me down yet.
$1900….heavy, sails, tubeless…hmmmm….no. But nice footage! Simon, you were putting some power into those pedals. Getting ready for another GCN competition?
With climing and wind gusts in mind. Would you upgrade from 30mm climbing (entry-level )carbon wheels to a 303 and 404 combo wheelset? or just 404s and keep the 30 mm wheels for bad weather? Im on a 2016 XSMALL TCR Advanced SL with rim brakes.
I know a little, it's a sum of a few force equations. 1/2.p.v^2, is a part of bernoulli's equation (usually includes +pgh and +pressure, but h stands for head height, in this case, 0), cd is the coefficient of drag (how efficient you are in a fluid), A is the frontal bluff body area, the m.g.sin(theta) is from newtons laws on an incline, crr mg cos(theta) is your rolling resistance (on an incline), Pabs usually indicates absolute pressure. a(m+1/r^2) isn't leaping out at me as anything obvious - it looks like it may have been a derivation of rolling wheel kinetics? But it reduces to am + a/r^2, which is just... Force + something really close to angular velocity. Anyway it's 1am I should be asleep. I might cme back to this if someone else hasn't looked at it.
Would pick Bora WTO instead of those any day. Cheaper, with superior hubs and more cool looks. Although subjective, the new Zipp logo is just poor. Old ones looked good.
The reason I would go not as deep that you didn't hit I believe is sidewinds. but the fact that like a bike they are getting an all-a-rounder that is pretty cool...my bike is the same and my riding is too and I am not going to have a stable of bikes (well I have 3) and wheelsets...ahh today I am climbing, ah...flat TT, ooh...gravely and that each is a different bike/wheelset. The 28s looked great in the vid on this, new wheels and SPD Assioma and I am "set" till I can make the Di2 change. And 4 watts, marginal yes but not bad there are plenty of more sketchy $/w offers out there
I'll stick to my Meilensteins thanks. ~400g lighter, and I got them 2nd hand for a lot less than these Zipps and I don't have to run disc brakes or tubeless tyres🤔
I enjoy all the content that comes from GNC. It's factual and it's entertaining. But no matter what the industry comes up with if your competitor has the same product you're all back to even again. But I deathly like the way the new bikes look
I like the tech but for my area a 50 mm deep rim can nearly push you off the roads some days. That's why I choose no deeper than 35mm or flat section carbon wheels like a Campagnolo Hyperon Ultra. It's not uncommon to have 20 mph to 40 mph winds in the hiills and mountain passes which can have brutal sidewinds that hit you when your taking a high speed corner. Very near pushed me off the road more than once. I learned only run 50mm rims on calm days.
On the SRAM website there is a Zipp 404 Firecrest Carbon tubeless and a Zipp 404 Firecrest tubeless. What is the difference? The carbon one lists the price at 1800. The non carbon? Says it is 1400. How are people figuring out which one they are getting?
Prime Attequer and Hunt Aero aluminum wheels match these for weight and are only a few hundred bucks. At $1900 you could buy quite a decent carbon aero bike or buy your friends or family a couple of nice beginner bikes. The actual gains will be just a second or two here and there. Exciting as the technology is, the price tag has to put a bottleneck on the review.
I cant decide between these and the 303 Firecrest. They appear to be the same price so its hard to see which one is better. Is more Aero better than lightweight and wider internal rim width? Zipp themselves tend to suggest better (less) rolling resistance and better vibration absorption can be more important to overall speed than pure aero design? - Appreciate peoples serious comments/suggestions! :)
because the 404s are deeper section rims, 404s are more aero than 303s...so what should really play a part is the terrain in which you ride & your weight. Since the 404s are deeper & more aero, you will go faster going downhills, on flats and anytime you're riding at speeds greater than 35 kmh. 303s will have the advantage only when climbing up hills & deep climbs because they're a hair lighter than 404s....but again, 404s can make up that disadvantage when going down the very hill climbed or on flats if you have more flat terrain than you do climbs. The last thing to consider is your weight. With the 404s being deeper section rims, they can have a higher chance of getting caught in crosswinds which is ONLY a factor apparently depending on your weight. I just got a pair of these ZIPP 404 Firecrest last week & rode the for the first time 2 days ago on a very windy day and I felt no effect of the winds on my wheels whatsoever unlike what other people claim about deeper section wheels. But then again, unlike many cyclist who are very skinny; I'm 6 foot 2 inches tall & weigh 220 lbs or 99.79 kg
Which is exactly what they meant. In the 2000s, the Next gen wheel just had to be lighter and lighter to be better. Then around 2012, the next gen wheel had to be more aero to be considered better. ZIPP recons that neither on its own is superior, all a wheel has to be is faster (ie more efficient). They claim their new wheel is faster without being more aero, by offering lower rolling resistance and being lighter, making it more efficient in general. So instead of “more aero”, it’s now about “faster”, hence “fast is the new aero”.
@@se7enTse7en To translate so far: Power at the crank = velocity of bike/coefficient of loss * (air resistance of wheel + force from road angle + rolling resistance + Pabs/Vb + force from non-gravity acceleration). Another thought, maybe P = Pabsorbed and it equals power at the crank minus power at the hub so it's drivetrain efficiency. Though then there wouldn't be any hub efficiency term. So maybe it's total power absorbed and it's not directly measured? I'm guessing Closs is the catch-all term for vibration losses that are otherwise hard to quantify? I also find it interesting that air resistance is a single term, it doesn't separate velocity and angular velocity. Final thought: is the system being considered the wheel alone or the whole bike? For a(m + I/r2), a = acceleration, I/r2 = moment of inertia / radius squared = mass of wheel, what mass does 'm' refer to?
@45 fottuto stronzo it’s actually an important marker for the launch. A problem with technology like power meters is scale-ability. Can you get enough of the parts you need to make enough product to turn a profit? If Wahoo are letting GCN demo the pedal, it’s a good bet that they have solved the scale-ability issue.
A set of wheels that cost more than both my road and gravel bikes combined. Doubt I'd be finding them second hand for a bargain.... I'll get more than 4w tucking my elbows in thank-you very much!
Great video, feel you guys don’t make as many of these sorts of videos as you use to… seems to be a lot more comical non-serious content coming out, and this video is precisely why I subscribe! More please 👍🏻🙂
Well scripted, interesting A roll, well shot B roll, looks like it took more than 5 minutes to shoot and edit. Please make all the GCN videos as good as this one :) Even if it means there are less.
Where does that fuss about aero come from? I think from manufactures. Most of the air resistance comes from the rider, not from the bike. Is it worth it to spend few thousand of dollars or euros more, just to save a few watts?
Honest question: Why not? The tube doesn't use the hooks(?); the TL tire would still grasp the rim. Secondly, there are also those Vittoria Airliner "pool noodle" things, but you might be giving a little of your weight savings back.
@@DEAR7340 The tubeless tire does not grasp the hookless rim. Hookless say use no tubes because they can cause the tire to come off. It's a major problem with hookless rims. A bad cut in the tire will leave you stranded unless there's a needle and thread in your patch kit. It's disappointing because it sounds like a development that benefits the manufacturers because it's cheaper and easier to make - and has some benefits to the rider like aero tire-rim seams and better impact resistance - but sounds like a case where they're taking our money for goods with obvious issues. The marketing feels devious to me.
@@pgreenx That most definitely is not the case. There are many independent channels out there that make a living on their own internal TH-cam revenue without selling out for ads disguised as 'content'
@@HGZie those independent channels also make content for the purpose of getting paid indirect add dollars from google/alphabet but I get your point and your right. GNC is not one thiugh
Shallower wheels are much more stable and more fun to ride in crosswinds. I don't see the benefit of deep rims, just get wheels with less spokes. Also with disc breaks you need more spokes making them less aero than a rim brake counter part would be.
I just got these ZIPP 404 Firecrest wheels the other week; put them on my Trek Madone & took them out for a ride for the very first time 2 days ago. Despite it being very windy outside at the time, crosswinds were not a factor whatsoever if that's deterring anyone from getting these wheels. I felt zero impact from the winds pushing my wheels any which way. Now just a disclaimer, unlike most cyclist, I'm not a toothpick. I'm 6'2" 220 lbs or 99.79 kg.
@@markmcconnochie4539 It's been 3 weeks now with them & I absolutely love my 404 Firecrest. And all of their ads about the Firecrest design with the dimples preventing crosswind was true. I have set PRs with almost every ride so far. Having been off the bike for 4 months previous, on just my second ride back I found myself increasing my max speed by over 5 kmh / 3 mph. I do a lot of climbing where I live in Texas; but they don't weigh me down at all. But when I am on the flats or downhill; I feel like a beast. They're perfectly stiff and handle extremely well on corners
just don't hit a pot hole, a decent size rock, and enjoy riding with anxiety that you aren'y going crash from a wheel failure when riding. Tubeless -> high volume low pressure
I HATE TUBELESS TIRES!!! I used tubeless for 1 1/2 years... AND IT WAS HORRIBLE!!! Tried different compounds. Hated them. I couldn't go more than 3 rides without the tire spraying me in the face with a puncture. I went back to tubes and I haven't looked back since.

ZIPP recons that neither on its own is superior, all a wheel has to be is faster (ie more efficient).
They claim their new wheel is faster without being more aero, by offering lower rolling resistance and being lighter, making it more efficient in general.
So instead of “more aero”, it’s now about “faster”, hence “fast is the new aero”.
@@LarsRR I won't be surprised if they will also start saying Aero is the new fast. Or faster is the new fast lol 🤣
@@sepg5084 🤣🤣🤣
I'd love an explanation of the equation at 2:47. Most of the terms I can figure out, but some such as Crr have me stumped.
The rolling resistance coefficient ?
@@ParMonts8ParVaux Good call. And I think "I" is the moment of inertia of the wheel. Thoughts on Pabs?
@@se7enTse7en To translate so far: Power at the crank = velocity of bike/coefficient of loss * (air resistance of wheel + force from road angle + rolling resistance + Pabs/Vb + force from non-gravity acceleration).
Another thought, maybe P = Pabsorbed and it equals power at the crank minus power at the hub so it's drivetrain efficiency. Though then there wouldn't be any hub efficiency term. So maybe it's total power absorbed and it's not directly measured?
I'm guessing Closs is the catch-all term for vibration losses that are otherwise hard to quantify?
I also find it interesting that air resistance is a single term, it doesn't separate velocity and angular velocity.
Final thought: is the system being considered the wheel alone or the whole bike? For a(m + I/r2), a = acceleration, I/r2 = moment of inertia / radius squared = mass of wheel, what mass does 'm' refer to?
@@se7enTse7en Good point! I missed the straight-forward acceleration. So it looks like the equation specifically addresses one rear wheel.
Did anyone else see the Speedplay Powrlink pedals on the Orbea at around 1:11?
@45 fottuto stronzo it’s actually an important marker for the launch. A problem with technology like power meters is scale-ability. Can you get enough of the parts you need to make enough product to turn a profit? If Wahoo are letting GCN demo the pedal, it’s a good bet that they have solved the scale-ability issue.
More affordable still meaning bloody expensive :)
nice Zipp commercial, GNC!!
Are these compatible also with none tubeless ("regular") tires?
I'll save the same amount of watts if I take a pee before a ride and at the cafe stop. It's also a lot cheaper and more comfortable ;-)
I am gutted. I have some Zipp 404's, but now I want the new version
A set of wheels that cost more than both my road and gravel bikes combined. Doubt I'd be finding them second hand for a bargain.... I'll get more than 4w tucking my elbows in thank-you very much!
Great video, feel you guys don’t make as many of these sorts of videos as you use to… seems to be a lot more comical non-serious content coming out, and this video is precisely why I subscribe! More please 👍🏻🙂
Insane wheel the best of the best !!!
Well scripted, interesting A roll, well shot B roll, looks like it took more than 5 minutes to shoot and edit. Please make all the GCN videos as good as this one :) Even if it means there are less.
deeper section wheels will still be faster, at speeds over 40km/h aero might as well be everything
Bullocks… this was an advert…. plus multiple adverts before, during, & after!
Who determined that they were the benchmark for aerodynamics? Independent tests show it is middle of the road.
Are aluminium deep wheels be as effective as carbon deep wheels?
Bikes are very expensive while the quality control is virtually nonexistent !!!!
Where does that fuss about aero come from? I think from manufactures. Most of the air resistance comes from the rider, not from the bike. Is it worth it to spend few thousand of dollars or euros more, just to save a few watts?
No.
4 Watts for an 85kg body mass. How many Watts do I save by being a 65kg body mass on affordable wheels?
Don't know: A new Shimano 105 bike or 4 watts(at 40kph and I have to put on some weight)...
Good point, aero bikes have basically displaced other bikes so just calling it a fast bike just means aero now days 😉
What do I do when I flat? Can't use spare tube on hookless...
Call uber with spacious trunk :)
Honest question: Why not? The tube doesn't use the hooks(?); the TL tire would still grasp the rim. Secondly, there are also those Vittoria Airliner "pool noodle" things, but you might be giving a little of your weight savings back.
@@DEAR7340 The tubeless tire does not grasp the hookless rim. Hookless say use no tubes because they can cause the tire to come off. It's a major problem with hookless rims. A bad cut in the tire will leave you stranded unless there's a needle and thread in your patch kit. It's disappointing because it sounds like a development that benefits the manufacturers because it's cheaper and easier to make - and has some benefits to the rider like aero tire-rim seams and better impact resistance - but sounds like a case where they're taking our money for goods with obvious issues. The marketing feels devious to me.

tour velocity wheels factory, talk about durable ebike wheelsets, brake pads. have ollie invent a single sided chain so we can have 24 speed cassettes
I laugh when I see dimpled zipp wheels covered in stickers which reduce the dimples!!
What Water Bottle holder is on the Orange Bike?
I think it's extremely stupid idea to put black bars around a video. C'mon guys, we got 2:1 screens in mobile and desktop.
hi. does it work with clincher tires?
Don't like GCN accepting payment for reviews/infomercials..... or Zipp for paying them
Every good/popular channel is just an advertising platform. Don’t like it either but that’s how it is.
@@pgreenx That most definitely is not the case. There are many independent channels out there that make a living on their own internal TH-cam revenue without selling out for ads disguised as 'content'
@@HGZie those independent channels also make content for the purpose of getting paid indirect add dollars from google/alphabet but I get your point and your right. GNC is not one thiugh
Shallower wheels are much more stable and more fun to ride in crosswinds. I don't see the benefit of deep rims, just get wheels with less spokes. Also with disc breaks you need more spokes making them less aero than a rim brake counter part would be.
I just got these ZIPP 404 Firecrest wheels the other week; put them on my Trek Madone & took them out for a ride for the very first time 2 days ago. Despite it being very windy outside at the time, crosswinds were not a factor whatsoever if that's deterring anyone from getting these wheels. I felt zero impact from the winds pushing my wheels any which way. Now just a disclaimer, unlike most cyclist, I'm not a toothpick. I'm 6'2" 220 lbs or 99.79 kg.
I’m between these or the 303 on my dogma f- struggling to decide. Don’t do too much climbing and similar size to yourself. Are you enjoying the 404?
@@markmcconnochie4539 It's been 3 weeks now with them & I absolutely love my 404 Firecrest. And all of their ads about the Firecrest design with the dimples preventing crosswind was true. I have set PRs with almost every ride so far. Having been off the bike for 4 months previous, on just my second ride back I found myself increasing my max speed by over 5 kmh / 3 mph. I do a lot of climbing where I live in Texas; but they don't weigh me down at all. But when I am on the flats or downhill; I feel like a beast. They're perfectly stiff and handle extremely well on corners
so quick!
Hi GCN...what model orbea in this video you used?
Orca OMX in frameset, or LTD if its fully built
@@CtFshd1812 i thought its was OMR
@@fiart1175 oh right, they mentioned in the streetfighter build, it is an OMR
Great wheels. Love them
Current price in US higher than my new bike.
If I can ride consistently close to 40kph then I’ll treat myself until then my old wheels will do.
Pinarello always did so with the Dogma.
What Orbea bike model is this on?
Dont forget,you have to ride downhil after climbing in most cases,so aero is the winner.
This wheel costs more than I paid foe my summer bike and almost three times as much as I paid for my winter bike.
I Ollie still talking to Si? As Si said "aero isn't everything". Maybe someone should ask GCN Tech, what the hell the equation means.
just don't hit a pot hole, a decent size rock, and enjoy riding with anxiety that you aren'y going crash from a wheel failure when riding. Tubeless -> high volume low pressure
4 watts from the previous version, at 40 kph is decent.
03:48
any advice? if i need to wrap a new tubeless rim tape
should i wrap over up the corner?
thank you~
you don't have to, as long as the tape covers enough of the rim bed to touch both tire beads
sheeeeeeeeeesh
I HATE TUBELESS TIRES!!! I used tubeless for 1 1/2 years... AND IT WAS HORRIBLE!!! Tried different compounds. Hated them. I couldn't go more than 3 rides without the tire spraying me in the face with a puncture. I went back to tubes and I haven't looked back since.
