How light?! Do you have a super light weight build?
Me big tubsie, so Steve won't let me borrow it. Perfect for the Flandrian cobbles mind. Or the Tesco's shopping run with a ginormous D lock.
6.28 kg cannonade Supersix high mod. Zipp 202s, I love it
This video made my bike feel like its been made of concrete actually.
I want to build an alloy hyperbike at less than 7 kgs :).
20 kilo ... and then I put my panniers on there.
There is no footage of steve riding the bike because obviously he rides naked.
AHHAHAHAHAHAHA
Thats nothing, I only eat an apple once a week and take diarrhea tablets to remove excess waste from my body before I ride my bike. I also only wear ultra light underwear to save weight. In addition to that I shave all my hair for weight reduction and removed all my reproductive and unecessary organs for weight reduction. So including my bike and my self weigh a total of 37kg.
@@hamedhaydari9581 did you write reproductive organs?
@@codexofficial9922 he had to sell his organs to buy his bike
@@hamedhaydari9581 That's still too much. I removed everything from my body, except my organs and head.
My organs are in a bucket, that's made of aluminum for weight reduction.
You need to do it, I have never felt so good in my life....well actually...I don't feel anything and my doctor says that it's a wonder that I'm still alive.
He also removed his teeth and replaced them with carbon fibre implants, saving 100 grams

@@leoaksil4085 do the british have teeth?
💀fuking dead
You know I sold all my organs to make my bike more aero

Steve seemed like exactly the kind of guy you would suspect to build such a bike...
hahahaha I don't know why but you are 100% correct.
Was really hoping Steve was going to be a heavy set bloke, smoking 40 a day 😂😂
Just like all those hyper car owners
You can't safely ride a lightweight road bike like this unless you're lightweight yourself! I think the main killer is the wheels, I believe these kind of wheels have a very strict weight limit. Also a heavier guy would tend to be too powerful for a lot of these hyper-light weight components.
@@alantaylor6691 yeh carbon standard are recommended for max 120kg riders. Lightweight carbon can be as low as 80-90kg. I think the hunt hill climb wheelset is a good example of low max rider weight.
My point was purely, the people who buy upgrades could do with riding up more grades before they do 😉
@@andyklyon Yeah absolutely. I don't know how true it is, but I heard that Chris Froome's race bike has a weight limit of somewhere in the 60 - 70 kg range. Even the high mod carbon frames take like around the 120kg area, so I thought that must be about the wheels. I'm also thinking that with the UCI weight limit, you could intelligently choose where to have the weight, as I heard that it's better to have the weight on the frame rather than the wheels because of the rotational weight of wheels affecting performance. So if you put more of the weight centre of mass as possible, then light as possible wheels, maybe that's better for performance. Maybe this is what Froome and the likes are doing for their road bikes, using the lightest wheels possible for their body weight, then putting the rest of the weight that they must more centre of mass.
Best comment. Everyone upvote
I’ll bet the money he spent building that bike weighs more than the bike.
probably not unless its in coins
@@Juiceboxer0 Haha get a life
@@masterbaiting9730 got one thanks
@@masterbaiting9730 you got me thinking so I looked it up. A dollar is a gram so it would be $4,280 if in singles. So it might have actually cost more. crazy
koglowa ok boomer
How to make it even lighter:
1. Smaller cassette and shorter deraillur for shorter chain length
2. Shallower rims for less rim material
3. Fewer spokes in the rear wheel
4. Drill holes in the saddle wherever possible
5. Pressurize the frame with hydrogen
Workout and lose 10 pounds
make it 1x removing the shifting mechanism from the left STI, the cable routing derailleur and 2nd chain ring. remove bottle holder
@@leonschumann2361 but then you need a larger rear cassette. Might aswell go fixed gear to go super light
@@EnterTheOrb yeah then you can even remove the brakes saving even more weight
Step 1: replace the 12 speed cassette with a single speed cog. chops the weight of the gears by about 80% and also allows you to remove the deraileurs saving even more weight
Him: "the pedals are quite unusual"
Me: "he doesn't really have any'
haha yes
I've saved 200 grams in weight on my pedals by only installing the axles, but my cleats weigh 300 grams each ;-)
umm, ever hear of clip ons? LMAO
So true
Well, after he drilled the lightening holes through his tibias he realised that he could just poke the bare pedal shafts into the holes and pedal that way. Brilliant really.
I can half imagine Steve going to his local GP saying "look doc if you take out my appendix now its gonna give me a weight saving of about 1kg, its unnecessary weight, man- I don't need it".
Nick Humphrey I’ll bet he has had an enema.
@Yard Sale Dale Like a sandpapered frame isn't painful? Buddy, i think he won't really care.
I wouldn't be going to my GP if I wanted a laparoscopic appendicectomy, to be fair...
@@paulcuthbert im not a medical expert anyone who interprets my comments in any literal sense might miss my attempt at humour
Probably had one of his balls removed to save som weight.. lol
Steve replaced half his words with "umm" for weight reduction
Those dictionaries are quite heavy.
🤣🤣
Lmao
This got me surpriselol
Lol
I had all of my bones replaced with carbon fiber for weight reduction. Soon I’ll be having one of my kidneys removed, who needs 2 kidneys anyway.
Finally somebody who's making sense. Bodies are where we can get the most savings in weight.
I’m also considering pulling a Lance Armstrong. No, I don’t mean EPO and testosterone, I’m going to have one of my balls removed.
@@Iheartdgd I chopped my feet a while ago. They implanted cleats in it's place.
I'm just a head. Best weight reduction ever.
I ditched my whole foot from the knee down, and have some carbon fiber tubes and cleats instead.
i love how he tried really hard to shave off literally grams here and there, but could not do without two bottle holders )
Arseniy Rastorguev Water is life in some places...
Arseniy Rastorguev Doesn’t matter how light your bike is if you’re sat on the floor next to it because you’re dehydrated.
Those are helium bottle holders not for water
taeril1 adding bottles of helium would make the bike heavier
@@umialam7408 not really
OMG look at steve himself. he weights ONLY 38 KILOGRAMS.
He is skinny because he can't afford to eat, spent all of his money on the build.
He replaced his bones with carbon fibre bones.
@@julianreverse these femurs weigh 300g a pair but Steve's cut off 10 cm because he doesn't need it

I'm personally not obsessed with grams but I would so love to try this bike out, if only for five minutes just to see how 4.28kg feel. I imagine it's insane
We would too!
@@gcntech WAIT Steve didn't let you take it for a quick spin?!
Yeah, why would I spend my money on the bike when I can still get faster through training.
Its me we speak about art of mechanics here, not a bicycle aiming at performance
@@danielbum912 If I had out hundrets of hours and thousands of dollars in a bike build from parts I wouldnt let any old cunt with a camera drive it either.
all talking about the grams, but no footage of the actual riding experience... wasted video
i hope steve not gaining weight so much these days
2.7g headset cap? Amateur.
I agree
Not really because riding experience is incredibly subjective
You'd better not be eating anything for a week before riding on this bike or you'll have wasted all that hard work
Me still wondering to this day how those pedals work
As if you hadn't had a broken pedal before and just pedal on the stem. If those pedals spin they're alright although I wouldn't bother. I think the grip will outweigh the weight loss.
Click into shoes lol
How are you gonna build a super light bike and add 2 water bottle holders?...lol
Stay hydrated
@@doomslayer5191 no. Water will make you heavier
@@LCST237 stay dehydrated?
@@doomslayer5191 dehydration = less water = less weight
@@andrew66769 I think you're forgetting the other effects of dehydration than just "less weight"
The Dirt on my mtb is heavier than this. And i clean it every week.
There’s still weight savings to be had. He could have sanded the tires, sanded the brake pads to 1/8 of pad left and dremel holes in the seat
I can't say I even disagree with the bike seat idea and maybe even more minimal pads.
Use Kevlar or cord spokes. Light on the grease. Narrower handlebar. No bar tape but roughen they bars. Remove bar ends. Change it to a one by. No from derraileur, one less chain ring, less cables, lighter brighter to just a brake. No valve caps if he had them. Shorter cranks….
Smaller chainrings and smaller sprockets and then take our a few links of chain.

@@MeenakshiDutta-cu5vi you're fun at a party.
I built up a very light retro MTB two years ago. The frame is a Sansvik USA made Centurion Titanium SX from around 1992-94. The complete bike weights only 8,4kg what is amazingly light using only bike parts from the early 90's like a Marin Titanium Stem-Bar combo, Selle Italia Flite Evolution 2 Carbon saddle, Syncros Titanium seatpost, Tune AC11 Ti bottom bracket, Grafton Joysticks cranks, Poggipolini Ti pedals, a light 790grams Shogun Zero cromo Fork, XTR M900 Deraileur with SRP aluminum bolts, Tech-Lite brake Levers, Dia-Compe 987 Cantis with Ti tuning kit, I also replaced all steel bolts and screws for titanium and aluminum screws and I replaced the original steel axles and the steel freehub from my XTR M900 hub-set and built in the titanium rear axle and freehub from the XTR M950 hub-set and an SRP titanium front axle. fotos.mtb-news.de/p/2428681?in=user
Now put 2 x 3.5kg U-locks in your backpack..
I was about to ride to work without my lock and this comment reminded me to grab it
Leave the lock at home and bring it into the office
@@suchasreallife Agree. If I can't bring it in, I ain't coming in.
LOL
And just don't slamm em on the frame
Me: so steve, what is it like to ride the bike
Steve: ummmm
Me: intresting, how fast can you go on this light bike.
Steve: ummmm
😂😂😂
"front end's quite light"
There is no way I get on a bike like this for anything other than climbing.
The aero looks trash ;-;
FYI: 4.28 K is less than 9.5 lbs... My customer/friend made such a bike at 11.2 lbs using a Storck frame, basically using the same wheels and components in this video. He quickly found out that it was very tiring to ride downhill as he had to pedal hard to maintain any kind of speed as his super Lt/Wt wheels carried no inertia. His hyper light bike taught me a lot of things about do & don'ts for racing bikes. For example, just before Kona Iron man, my little pro shop in Seattle fills up with incredible TT bikes for last-minute tune-ups. A woman pro of short stature using 600c wheels was ill-advised to switch from the old ZIPP carbon/alum wheels to the new lighter ZIPP all-carbon wheels which are about 400 grams lighter. I told her the wheels are far too light as they carry very little inertia to help you maintain speed on those long, flat, windy Kona roads and will be hell to pedal in a headwind. She said she got the advice from a pro rider and is going to try it anyway. I advised her to take along her old ZIPP wheels just in case... A few days later she calls me from Kona telling me during practice her bike was extremely slow wondering if her brakes were dragging or if her rotational wheel balance (which I do), somehow got messed up?!?! Right away I knew the problem and reminded her how her new ZIPP wheels were too light. I then asked her if she took her old wheels? In a puzzled voice, she said "yeah, but why?" I told her to put on her old ZIPP wheels and go practice, problem solved. Sure enough, she calls me the next day all excited telling me how fast her bike was.
Now when she has a race with a lot of climbing she uses her new Lt/Wt ZIPP wheels. And when she races on flat fast TT courses like Kona she uses her old heavier ZIPP wheels with great success.
Conservation of momentum at it's finest! It's amazing how many cyclists - especially those with the money for multiple sets of carbon wheels - don't realise the difference it makes. Sure they might be more weight to lug up climbs, and sure they might be a bit slower off the mark, but the trade-off is not needing to accelerate nearly as much or as often since you aren't slowed down by the average undulation in the road!
That ax-lightness stem looks like it needs to visit a urologist...
Vee_DT or needs some viagra.
you mean eurologist :)
Still see alot of weight, and my stem cap combo is lighter than that setup.
peyronies disease is no joke XD
Why two chainrings?
People are commenting that this bike would be unsafe but if all the individual parts are sound there is no reason to think they will fail.
"Steve managed to cut out some fat and inner skin from his cheeks (nice hack!) and saved 500 grams !
Haircut, ONLY 30 grams!?!"
LOL! ! ! !
what about the pedals? you didnt ask steve about it?
No ball bearings in these pedals, just DU bushings. I wonder how effective is the power transfer.
Ultralite Cirrus Ti
Apologies about that, i did ask him, but forgot to include it at the end of the video. Basically, the pedals are mega light but a lot more difficult to click in and out of compared to a look or spd sl. Being much less practical, Steve says that most of the time when he rides the bike, he actually uses shimano pedals, but will use the mega light ones on special occasions.
Oliver Bridgewood that’s exactly what I wanted to know. Clipping in and out of that! I hvnt seeing that type of pedal before.
@@marlondecarne7118 you can probably find old articles from the time they were released. The downside is that to unclip you have to push the cleat inboard and lift. Obviously Shimano is much more practical (and I changed the spindle for ti in those ones too to keep the weight down)
Who in the world would carry 2 water bottles riding this bike?
I use it for training so gotta have 2 bottles for longer rides. But yeh I could've taken 1 off for the video!
True, looks like massive faux pas :)
@@rappide 😂
And if you WERE carrying 2 Litres of water it would rather make a mockery of the rest of the weight of the bike.
The water he carrys actually has the second hydrogen molecule stripped off to save weight.
Next time: Fill the frame with hydrogen to make it lighter than air!
smart
Sm🅾️rt
Helium would be safer. Somebody did a study before by filling in helium gas into a rugby or football, but there was no significant difference in performance.
@@ypsiow1008 well this is bikes
where you have 70-kilo persons ride 4kg bikes and what to lose 500g of the bike to get faster.
I actually would like to know if you have a team of pros(for the sample size) and split them in 2 groups. they all ride their normal bikes, but for half of them there was 500g/1kg of weight added into the lower part of the frame, and for the others not. The next week they ride the same route, but the riders that had the weight added don't have it that time, and the ones that didn't have it get it for that ride. You then could compare the 2 results.
or just vacuum all the air out
will it shatter when you hit a bump?
doubt so, the frame still has the structural integrity of a cannonsale supersix evo
Curbs are not for touching.
I once hit a pothole and had to sell both my car and wife
A bump is not something that you would hit on a road bike.
no, it will fly away
Bottlecages, ..... 2 of them ????? this guy is nuts
Team Lumixgear bottles of hydrogen I’m sure:)
we all wanted to see Steve riding the bike, and hear how it feels compared to a heavier bike...
I strongly recomend filling the tubes and the frame with helium.
Helium adds weight, at equal PSI to oxygen, since it is a less dense gas. You need more helium per square unit of space to equal to the same pressure which means more weight
@@MetalY2KMusic helium is lighter than air, so bike mass will be more, but it weight is less since it now trying to fly away
@@micronyaol If you had an equal amount of density in the gas, yes, but if you go for equal PSI that you would have in air in the tires, they become heavier since there are less molecules because it is a less dense gas.
@@MetalY2KMusic that's not how it works. Ever heard of pV=nRT? Pressure is proportional to the amount of gas molecules, not the mass of the gas.
According to your logic, helium balloons would just deflate until they no longer provide lift because they provide less pressure than surrounding air.
@@kotofu Somewhere, you misread what I wrote.
That's not my problem.
You don't want to debate the actual topic of adding helium in place of oxygen to bike tubes will mean more weight, because it's true.
come on guys. It might've picked up some 5g dirt if he test drove it.
true actually. My mtb weighs about 15kg (including all commuting accessories). It got 100g lighter by cleaning it after 400km
As a Junior rider I had a trainer who has asked us to train instead of drilling wholes in the chain wheels and brakes
The trainer became later DS of a pro team with two wins in TdF- he told a friend of mine that Hinault just rode the material of the sponsor and didn’t care for tuning
Steve's working to reduce Earth's gravity in his next project
100kg Man on Equator is lighter, that if he would stand on the Pole, on 300g.

I was really hoping Steve was revealed to be 6’4” and 15 stone
I appreciate what’s been done here as a demo exercise but I think once you get down to a certain minimum weight function is massively compromised. I bought a hollow link chain and the instant I met a hill and put some power down it instantly snapped. I’d hate for something more important like a handlebar to fail doing 60mph downhill 🙈
Yeah I snapped a chain on an uphill once. Not fun. I'm way more interested in structural integrity than in light weight.
How many miles had the chain done? My normal KMC chain snapped after ~2000 miles of use.
@@EnterTheOrb i assume new.
specially for people like me that love to put as much brute force into pedalling as possible on a sprint, for the fuck of it, that bike’d probably feel like a twig
the drilled brake levers give me anxiety
and then its a windy day you go in the bar for a drink and you come out to find your bike has blown away
"So how much of this bike is carbon?"
"Yes"
I remember lining up in a race against a guy who'd done similar to his bike, I avoided him in case he hit a small pebble and it broke something in half :)
Watching this as a mtb rider i get more mud on my frame than this bike weights
My favorite vid. I actually watch it every couple of days for inspiration. just when I think I'm some kind of bike geek, I look at this.
Steve is one of those vegans who peels his bananas in store before taking them to the check out xD
This makes no sense
I don’t get it
I heard he picks the seeds out of watermelons .
Plastic sugery
I heard he drills holes in his condoms to save weight.
Comments are very hilarious..
They made my day 😂
Building a bike like this required 2 things :
1. High paying job.
2. No families to feed.
You forgot OCD.
I'm waiting for someone to make a bike out of dark matter.
Soon after, they'll make an E-bike that runs on dark energy.
His last name is Rose, imagine he was your teacher in school and you had to call him Mr Rose 😆
'...and the skewers, well they are made of lead, no only kidding' HAHAHAHA!
Imagine doing a wheelie on that bike and the wind is super strong
I just realized that weight reduction on bicycles is an addiction worse than gambling lol
I enjoyed reading through some of the butt-hurt comments of envious people... I don't care about light weight builds personally, but chapeau for the nice build Steve!
And here I'm trying to keep my new bike under 8kg...
llandor replace the front wheel with something smaller ;)
Yup, considering a new set of wheels to put mine under 12kg.
Both my event bike and my commuter sit right around 9.5kg, though the commuter has got to be closer to 10 now with the lighting setup and the excessive use of reflective tape. I'm hoping to cut down weight on my event bike but money is always an issue
@@SonjaTheDork My commuter is a gravel bike, alu frame, steel and alu forks, cheap unbranded wheels. Have never weighed it with my lights and bottles but I'm a hair over 12kg with pedals. £500, eats up the low quality tracks I ride into the city, does its jobs perfectly (Voodoo Nakisi) My 'nice' bike is just under 0.5kg heavier, but it is a fully suspended mountainbike. :D
I should probably buy myself an actual dedicated road bike at some point lol.
CAElite || I'd like to get myself a gravel bike myself for commuting, or at least something that can handle a bit of snow and slush. My current commuter is a Trek 1.2 road bike that I used to use for events but I started to use it to commute to save money on gas. My event bike is an '04 Trek 1200 fitted with an older Shimano 105 groupset. Not the pinnacle of road bike technology, but it just feels great and faster than the 1.2
Steve turned out way calmer than I imagined him.
Whoa that insane built steve! I like it. Now i feel my bike like a concrete now.
Awesome, this allows me to have 4-5 more beers than usual before my bike rides and still roll with the same weight. Worth the investment in my view. 🍺
was waiting for you to drive it!!
I was _weighting_ for him to ride it
Ooff
That bike is lighter than my history textbook...
Still more heavy as the history book of the state of Palestin
@@Zozo806 *Israel
Nice
Plot twist: Steve does not even ride bikes. He actually hates them. He just made this to piss everyone off.
Why bother having 2x ??? Would save a few more grams without the front mech and an extra chainring.
Sub Mariner_38090 I have a fibre lyre chainring - the salesman told me that those chainrings can’t take more than 1000w. You need to go for the aero one which is slightly heavier.
He’ll need two if he decides to sprint mid ride!
@@david131092, thanks for the info, much appreciated. I was under the impression that Steve was just trying to save weigh but you're right, if he needs to put more than 1000W that's the way to go. Although it may be extremely hard to do so give the pedals he used 😉 Hey, just kidding.
Going 1x and other hacks used by the UK HC scene will save weight but a lot of weight weenies prefer to try and keep the bike as complete as possible. There's just something nicer about having a mega light bike that is still "normal". That 2.7kg bike from a few years ago was also a standard spec so the shortcuts are not really needed if you're still above 3kg.
@@philadams9254 that makes a lot of sense. Thx!
I believe there is some type of "qualification" with this whole weight thing - they require it to have 2 bottle cages and a front / rear der. Seriously, I'm not speaking factually but what it seems to be online, on blogs and such.
It must feel amazing to ride, for me an 8kg bike feels incredible to ride due to the lightness. I can only imagine 4.28 kg would feel like riding the wind.
I have a 4.5kg bike - based around the same frame as this. Best not go no-handed in a crosswind!
I've also got a 7.8kg bike which feels like a steamroller by comparison.
Wow Steve seems like a bag of fun!
I can undo this with one Sunday lunch meal
I mean it would pretty cool to see someone acatully ride the thing , but whatevrr
You could definitely ride it around the house. But... Would the bike survive that ride? )
Don't think this bike is rugged enough for daily use. May be keep as a furniture or put in bike museum to be admired.
That aluminum cassette has a lifespan of about 200km, maybe the carbon rings are worn out even before that.
Fake news. I've heard similar anecdotes about longevity as well by others who've used and raced with them. road.cc/content/review/121996-fibre-lyte-aero-carbon-chain-ring
@@stevenrose3352 He's correct about the aluminium cassette though? There's a reason they're mostly steel, and possibly titanium but only for the larger cogs. Aluminium just doesn't last very long there.
That being said, the bike would be way below 5 kg with essentially no sacrifice in functionality, durability or comfort. It's impressive. In addition to the cassette, I'm mostly thinking about double pivot brakes, "normal" cables and casings, normal hoods, softer bar tape.
On the other hand, you could shave a fair bit from the wheelset, 200 grams or so I imagine. Some tubular rims are lighter, especially if you go for low profile. Also, I think those are Tune MIG70 and MAG170 hubs on the wheels -- very nice, light and durable, but also Tune's cheapest model. :) There are some exotic ones that use straight-pull spokes without flanges, and have carbon fiber axles.
@@Antti5 yes. So many comments - I think I answered that to another response already. But I agree about the durability if the cassette. I could splash a lot on an AX 25mm deep wheelset with Extralite SP hubs. But it was fun experimenting with a few DIY efforts that continued to shave weight and didn't really cost anything :)
Those recon blocks suck. But that’s no the point with this bike. i have the saddle on my bike. It’s awesome and causes no discomfort on 6-8 hr mountain slogs. I would ditch the stem purely from an aesthetic perspective (for the THM one) and the lever hoods. I would swap out the pedals to for something with a platform. Purely personal preferences. Great build and interesting vid.
@@DrJRMCFC I have no doubt that the AX Lightness saddle can be very comfortable. I''ve been running the sub-90g Tune Komm-Vor+ on my road bikes for many years now. Yes it's light, but most importantly BY FAR the most comfortable saddle I've ever ridden. I never had any comfort issues, and some of my rides are 10+ hours. If they ever stop making them I'll buy a dozen just in case.
The shape is just right for me, and due to the lightweight construction it's actually very flexible and absorbs bumps well. There's absolutely no reason why it would need any padding. I do have one with leather finish on my titanium bike, but just because it fits the aesthetics better.
That's an awesome bike build. Well done Steve!
Steve donated a kidney just to reduce weight, true story!

"Oh and did we mention that Steve's also filled the inner tubes with helium"?
Steve removed 30cm of himself in a surgery, so he could weight 7.25kg less. Eventually he will remove 2 fingers to save 26g.
Dont ride cobblestones with that 😂
G7R611
Why?
That is very light but not insane light.
It has a proper frame and wheels
@@mikicastan Cobblestones on 22 tires? The bike will survive, but the experience will not be a pleasant one.
arnoldhau1
Tyres can be a problems but rest of the build are totaly fine even for the cobles
I wouldn't dare fart near it.
@@mikicastan what do you mean its not insane light?? Its 4.3 kg...
"seemingly no stone has been left unturned in the pursuit of making it lighter..." but didn't you just say he could have opted for a lighter saddle? 😂
Show us Steve's *drilled out metatarsal bones,* that fit his pedals.
Prisoner: Hey man...so what are you locked up for..
Me: oh. I just but an illegal 4 kilogram bike.
george ismailov it’s illegal under uci regulations. He could never race it. It has to be like 14 pounds (6.3ish kilos)
@@nicholascash7002 ah you know what i mean..
I just but?
@@nicholascash7002 the UCI weight limit is exactly 6.8 kilograms. The UCI is metric, NOT imperial.
MinecraftCalzone yeah I know. It was just an estimate based on what I remember from racing. I had friends have to strap rolls of quarters on their bikes to make them legal
Imagine riding this beast on windy day. Lmao
I don’t think you’d be riding it for very long....
look at his little face going through the numbers.... love it
Weight loss is poor mans superbike
you could buy a real superbike for the price of this
Yeah, this thing is crazy expensive. All these parts are ultra expensive and niche. (Other than SRAM Red)
@Mr Brightside but, the more exercise you get per km, the more limited your range, and lower range means more limited routes and boring scenery. unless you're doing laps, then that doesn't matter. i'm fine with my bike and it weighs like 12kg or something. it's a 30 year old aluminium frame bike.
@Mr Brightside nah you had a point. i'm just nitpicking.
Bike: weight's 4.28 kg
Owner: I'm too heavy to ride it
Owner: I need to lose 10 kg (or about 2 bikes worth)
If the bike was any lighter you won't have no more bike😂😂
Imagine just seeing you friend measure weight on his bike while you slap new 2.3 thick tyres on your bike.
And then there's me with my 46lb mountain bike
The biggest differences for me. going from a aluminium bike to a carbon bike Was the stiffness of the frame. Not the 4kg. It was lighter
You didn't ask about the pedals!
Doh!
I have Aerolites . Nothing fancy . Just a plastic tube over a metal axle with zero float and no bearings . Hence why i removed mine
Not shown in the video, the rider loaded up his water bottles with... you've guessed it! Water vapor.
Stem: before I saw this video
Seatpost: after I saw this video
Oh come on!! At least let someone ride the bike, almost 9 minutes of my life and you didn't even ride the damn thing. 😤

That were my thoughts. Does it even ride?! :D
@@fab9727 For a short time it will. But carbon and aluminium chainwheels will be worn after a couple hundreds of kilometers.

Let's plug the gcn host teeths to substitute the sprocket n reduce further weight
Aluminum cassette vs steel chain this high engineering solution 🙈🙊😂
Underrated comment right here.
This cassette is the one thing that gives away the fact that this is only a show bike. Such a cassette lasts around 300 km. Recon would also make titanium cassettes which weigh around twice as much. But this could be compensated by lighter lower profile rims. It‘s an uphill bike, so who needs high profile aero rims for climbing mountain passes?
Lmao
Alu, but ironically with 10 (11?) cogs. Losing 3 or 4 of those would be a decent enough way to save a few grams. But hey, we've all been riding with alu chainrings since decades ago and they last OK.
Make it a single speed and remove hand brakes to gain some more weight reduction?? :)
it cant handle alloy cogs andbthe fixed gear stress it will break off
paper weight fixed gear, interesting
Yes plz
Who else only has fixies
I think fixies should be banned, imagine a supra driving around with no brakes
Agreed.
To us fixie riders all those cables, gears and derailers look awful.
this emminates the same energy as a speedrunner doing as many time saves as possible
That's nothing compared to my 4.28 tons Mountain Bike.

Make the whole bike air tight,and replace the air inside it with helium,and I wonder if it could do what the bmx bikes did in ET.
Stayshtum68 i think hydrogen is lighter than helium... they should put hydrogen in there haha
@@Freak001100 depends on the isotopes, H³ would be about twice as dense (assuming pressure and temperature stays the same) as He³
Isaac Karjala yeah but i mean H2
@@Freak001100 H²[2] would be roughly the same density as He⁴
Might as well leave a vacuum inside.
I am late to watch this but still amazed by the features it has to offer.. Wow
So you did everything except ride the bike -. -
we should appreciate that he picked it up for us with 1 finger
