The World's Lightest Steel Road Bike | 5.42kg of Marvellous Metal
ฝัง
- เผยแพร่เมื่อ 14 ต.ค. 2024
- This Yasujiro Svelte weighs just 5.42kg, which we reckon makes it the lightest steel road bike in the world. This frame is constructed from the brand’s premium double-butted Ultimate tubing.
The walls of this tubing are a mere 0.35mm thick (!) at their thinnest point. This ultralight tubing is at the heart of this remarkable bike and we are utterly in love with it.
The build of the bike is (no surprise) fairly premium, but it doesn’t feature nearly as much crazy carbon exotica as you might imagine.

My main thought is "fantastic, hill-climb diaries are coming soon". It's a beautiful bike, but hill-climb season is the best diary season... :-)
Love it! More content like this please.
1.24 Kg is impressive, this is about 300 grams lighter than a silver fillet brazed 55cm Ishiwata 015 frame I put together about 25 years ago. If I had used 753 Track chain stays and not used a brazed steel seat clamp it may have lost another 100 grams.
It was similar to a Vitus 979 in stiffness and very lively but much more comfy. It was painted luminous hot pink and had 753 forks.
Please use a medium 56cm. Never use a small frame size. Does not do justice. Yeas size xxs can do 4.8kg as well. Size what...
I love my bike and I love riding. This is a beautiful bike. I love the color.
Guys, your endorsement of external BBs and external cabling just warmed my heart!
Great to hear and thanks for watching! Joe & Jack.
Nice bike. You can get Reynolds 953 a whisker thinner than that (0.3mm at the thinnest point, 0.5 at the butts) but the real weight saving would be the paint as 953 is stainless so you wouldn't need any.
I really really REALLY like this bike. Surely because it's so simple.Surely because it's so niche. it's so simple and elegant tho. the pink also is spot on. now i want one :(
Yes! finally Steel! Thank you Cycling Gods!
I'd be even more impressed, if they had built a matching steel fork, which might be 300g or so heavier.
Stick a set of Precisa forks on it it'll be fine.
Agree, might as well have a steel front end and allow for some bunny hops when need be!
I saw one of these at a local shop before Covid kicked off. It was a customer bike in for a tune up. I wanted to own it immediately. The shop owner couldn’t recall the exact price of the frame but he said it was surprisingly good value.
More so at current prices I suspect
Threaded BB will be easier to live with.....cut outs on the BB shell to let road grime into your lovely frame and around the BB.....not so much? Still, lovely looking bike 👌
Maybe but often it's good practice on steel frames to have a drain hole as it's quite easy for water to get in via capillary action down the side of the seat post.
The bearings are sealed from the inside and the rotating spindle should have enough clearance for grime to get in there and not cause too much mayhem.
To everyone complaining about the bottom bracket holes, dont be ridiculous! This bike is for, at most, riding on a blistering summer's day, not more than 2.35km to the nearest cafe for 1-5 cups of espresso. U must then have ones significant other pick you up in the range rover for the return trip. The Hungarian visla may ride in said range rover only if separated sufficiently from the bike
That bike is absolutely lovely. Just love it. Wish it were mine.
More Joe, Jack & Felix, please BikeRadar!! 👍🏼👍🏼
Yes a steel road bike. With carbon wheels, fork, saddle, seatpost, crankset...
Stick a set of Precisa forks on it it'll be fine.
This thing must ride butter smooth though
The frame is steel but everything else is carbon or aluminum. I remember when internal cable routing came about 20 years ago and everyone was impressed about how much better the bikes looked and how much easier they were to clean. Now all of a sudden we want crappy steel frames and external cable routing?
@@crooney82 A lot of people didnt stop wanting steel and external cable routing, it's all about a machine being fit for its intended purpose, though I admit the bike in the video has little merit as anything but an object of desire or perhaps a technical exercise.
@@crooney82 yes, because cost and maintenance is a far greater concern to most people than looks and negligible aero benefits. Also steel rides way smoother
I have 2 questions, I know that steel framed bikes tend to have a really nice ride quality, so when will it be tested on the road? And with the cut outs under the bottom bracket, wouldn't that be a setup for enormous amounts of corrosion and weakening the integrity of the bottom bracket and cranks?
BB cutouts were pretty standard on road bikes for decades. I have two frames with cutouts. They are not ideal for wet climates though. That said, my Ciocc is made of a basic Columbus and was used as a winter commuter in Scotland in a previous life. The frame is quite heavily patinad with rust, but none is structural. Most high quality steels don't decay like the underside of a car, and modern BBs have a sealed sleeve to protect the crank (old 3 piece BBs had sleeves too, they just weren't as good at keeping out water and grit).
In fact the hole protects you from (too much) rust on the inside of the saddle tube. Water comes in through the seat post clamp anyway. So it must go somewhere.
you need those holes to drain water inside the frame, it would be far more likley to rust without them
Insanely beautiful! I love it! And yeah, I prefer steel over plastic.
I'm yet to see a plastic bike intended for grownups.
@@LeoInterHyenaem you know, that "carbon bikes" are actually "carbon fiber reinforced plastic" bikes, right..? 😉
@@StopTheRot because it is. And sounds like plastic, when you tap it.. 😆
@@StopTheRot because there are no actual carbon bikes. It's all carbon fiber reinforced plastic.
@@dpokladek yup! That's why they can't be recycled. Awful for the environment
I now have a build list for my 5 kilo S-Works Tarmac.
I love steel bikes it helps soak up a lot of bad roads.I've got a Surly Pacer, Surly Midnight Speacial,and a flip flop hub Nashbar
After braking 2 aluminium frames from fatigue after roughly 30000km each I went back to the trusted chromoly steel and haven't had problem since. And if it brakes I can simply just weld it.
So beautiful 😍 I love steel bikes! I do know there was an Eddy Merckx steel bike in the Tour de France this year!
Such a Beauty! Almost made me cry...
Oh great they finally figures out how to justify charging car prices for steel bikes now
It's a beautiful bike and by the way... Totally love your video! You have great voices for this type of vid 🙏🙏🙏
I'm building a NOS Miyata Team frame that is also Tange tubing. I'll have to ask the guy @ the bike shop doing the assembly how much the frame weighs. It's either 48 or 49cm. I've had it for years & am just now building. I found the perfect Campy group & have Spinergy wheels on another bike that will worko. Also have some blue anodized Wolber rims & a front Chorus hub with the grease port. Need a rear hub but haven't spent any time looking for it. I am not trying to build the lightest bike. I already did that with a Lemonde carbon bike. I got it down to 16.2 lbs. Without getting tubular tires or super light carbon wheels & swapping out some parts that weren't picked for weight in the beginning of the build. I became a gram weenie about a year after I'd been riding it. I know if I throw enough money @ it I can lighten it substantially but I have other projects now. I'd like to see that bike & pick it up for comparison to mine. It's nice. 👍🚲
Love this, just a bit of fun. And I agree, aesthetics matter.
What a beautiful bike. Convinced me that my next frame should pink.
I still own an old steel tange Infinite Schauff hurricane xt Mtb in 18"/m frame from the good old days and the frame is not that heavy, although I have never weighted it on its own. The bike with full xt, crossmax wheels and indy xc all from 98/99 did tip the scale at 10.5kg
Yes.but cromoly double butted and reinforced head tube. They are light because they're tiny frames.
a SEABOARD chrome molybdenum steel frame is also 1665g. I have one and has a total wt of 6kg.
Nice bike and interesting that the boundaries are still being pushed with steel. Would be interesting to see the bike perform under stress. Cool thanks for a well presented video guys. All the best Andy
Great video guys. You earned a like and my subscription.
Tyres are Tufo, cables are Alligator, could be lighter with a 30mm axle and a Rotor cassette,
I went back to steel with a Ritchey Road Logic. It is not much heavier than my Trek Madone and rides better
I've got some solid wheels (Mavic OP UST on CK hubs with 32 spokes) and 28 pro ones with a 105 build. Sprints or climbs and descends as good as any of my mates bikes but is super smooth and has great comfort! Could have less spokes or upgraded gears but it wouldn't be much better!
I too went to steel Ritchey Logic after numerous plastic bikes, more solid as opposed to hollow feeling, more solid and less creaks and crackles. Best bike I’ve owned hands down.
MrMassproduce201 By plastic do you mean carbon fiber? My best friend has a Ritchey Logic steel road frame & I'll never forget the look on his face the first time he pulled my carbon fiber Lemonde out of the back of my SUV. It was like, my bike is so heavy it's practically an anvil, her carbon fiber bike weighs about as much as a cup of coffee. What the frak? I don't have any creaking noises. Maybe your plastic bike was a really cheap bike?Mike’s bike was rather pricey BUT IT’S HEAVY. Bottom line: heavy sucks. 👎🚲
@@secretdaisy6484
heavy bike are completely justified, you don't feel thing on them that's why they are used for touring
don't have to worry about pot holes or any cracks.
Exactly,I ride for fun,I like to enjoy a nice riding hand made bike. Especially on fast downhills. Legs and lungs count a whole lot more then a lb or 2 on a bike. I dont make a living riding my bike,99.8 % of us dont.
Very nice. I’d have one.
1:11 - apart from a future rust source, what’s the benefit of the cutouts in the bottom bracket?!? Surely for saving ~10grams it’s not worth the risk of road spray and sand etc getting in there?
Let’s water out that’s got into the frame elsewhere
Some electrical tape would save the pain. Easily replaced, would keep the grime out. Also for weight weenie price point - excellent!
RIDE IT
Don't just talk about it! !😤😣
If Yasujiro would like to send me one in my size to ride this hill climb season, I will gladly review it ;) Thanks for watching! Jack
@@bikeradar Surely you have a member of staff small enough to ride it?
they don't have permission obviously. i don't know but i think they borrowed it on the way to somewhere else.
Nice clean bike but i am not fan of pastel colors to paint the frame and what are they thinking to make holes in the bb area is a good idea?, well at least is a screw bb, imagine the nightmare if it was a pressfit bb.
Jacks outfit's on point!
Stop, I'll blush 💅 Cheers, Jack
I am really impressed, the frame is nearly as light as my OCLV carbon 120 frame in the same seize.
Would love to have the data after putting it through its paces...I'm especially wondering about stiffness.
That's a beautiful bike. Hopefully if I get a 100 on my Algebra 1 exam... my mom will consider buying me a new bike. =)
7 months later.... did you get a new bike?
@@ilikelampshades6 I am happy with my bike. Too bad I cannot ride it at this time. Thank you. Hope you are well.
Very cool presentation style 👍🏻
So much better than the commercial sell out at GCN! Had lot of fun watching; As allwasys ;)
Great review!
Would love to see a road test for the bike. 👍
“Tange” I think we have all mispronounced that company name.I see steel and Ti having a resurgence and hopefully Tange starts selling gravel and hardtail Mtn-frames.
thats one of prettiest bike i ever seen,
Art on wheels
Totally fallen in love with the frame. Anyone know how to buy one in Europe?
"And we'd go carbon"...I love that. No fear. Just reality.
Would make only 300-400 grams difference. The most weight saving potential lies in the components.
Utterly stunning. Beautiful colour. Just checked the Yasujiro site and they make some lovely frames. Check out the Cameo.
you guys always put a smile on my face :)
1/4 fart could be shed by removing the protective film from the headbadge. 2.4 farts could be shed by paintings badge.
Flippin heck i could consider steel again.
The frame is only 120gms lighter than my 2004 Giant Tcr performance series Aluux SL as used by Team Once back then for the whole seasons racing, whether TDF, Roubaix or TT's.
No doubt about it the TCR is much stiffer & so a better performing complete bike.
What about the price?
Rob English built his Stainless Superlight to 9.94 lbs or 4.5 kg
I just took a look at it. He also had to use carbon components. Someone out there must be building an all steel (no carbon) or all aluminum lightweight bike...
I love the color.
This type of cabeling vas developed by Nokon a long time ago. It is not a JagWire thing...
Simply the worst cable system I've ever used too
@@ErzbergAdventures and also the most expensive...
@@TheoreticalCyclist I liked the concept and it worked really well for a few rides but then it was nonstop issues
@@ErzbergAdventures We used to use it in small sections for the rear deralleur and rear brakes (V and mechanical disc). But the best cabel system I ever used was the one that came with the SRAM 9.0SL group set.
Beautiful
The cable housing appears to be Alligator.
I don't care for this bike's:
- reverse slope of the top tube (fixie type). I much prefer higher front end and lower rear end top tube design.
- external cable routing. My preference is internal.
- the bottom of the fork. My fork design of choice would be a full carbon one.
- although these brakes may be among the best rim brakes save for the hydraulic ones, they're still rim brakes, meaning - designed to destroy beautiful carbon rims with use.
Cool.
Tyres are Tufo Elite Jet tubular 20mm
It's not real steel. It has steel frame but apart from it, everything else is carbon and alloy. If you look at the specs, the weight can be achieved by any frame with those expensive parts.
Wtf did they think when deciding to make holes in the BB shell?
Literally this: "if any water gets in there, it will flow out immediately without causing any rust issues, just as it's done since 1920s"
@@robertkujawa3504 Or: Seal it and it wont get in on the first place.
@@robertkujawa3504 and what about mud and sand
@@obi-wankenobi9871 yes it will, through the seat tube.
@@vedadrokkor what about it? This is a bling road bike that is never gonna see any mud, and if any sand gets in there... rattle it out? A quick blow from a compressor takes care of it? Heck, you can even safely flush it out with water, as it flows freely and dries quickly.
Wow. Just wow.
I guarantee that small chainring would fold on the first steep hill for anyone over 70kg!
I believe that is a possibility. Some things need structural strength. The chainring is definitely one of them. Maybe lightweight hardened aluminum is possible while maintaining strength.
Props to Yasujiro for managing to make a steel frame that thin and light, but I'm dissapointed how much weight savings are credited to carbon components, I would have preferred a full steel bike
there’s full carbon rim calipers now, 100g lighter than cane creek ee
Steel is real
these available in the uk ?
I just weighed my steel bicycle today and found it was 18kg 🙄
How do you spell that component brand?
Be King
If I ever get another road bike, this is on my . . . Radar 😎
🚲📡 👌💞
How does this tubeset compare in weight to the old True Temper S3 set?
Jim E or Ronalds 853 & Columbus Spirit HHS tubing for that matter
Looks sweet but it's going to be noodly as hell...and those brake bridge ornaments will be a pain in the butt to clean ;)
I want it but how much is it?
Lovely bike.
What a amazing machine! I'll take one please.
Can somebody direct me to the webside of this mysterious component supplier (stem, seatpost, wheels, etc.)? Couldn‘t find it - thanks!
great, all the water will get in there
Count me in!
how much the frame fork? when it can be bought?
This brand name could be a good thief deterrent in the Philippines.
Tange is, when what you tell someone that they are stupid but you don't want to sound rude. You only say this to a person that you have a close relationship with. Rudeness factor depends on how sweet and melodic you say it. Ranging from flirty, to comedic, to non-challant, to borderly rude and anything in between. (Tanga is the rude version)
read: ta-ngê and ta-ngā
I'd love to have this bike. 😄
haha you two have perfect chemistry!
Now this is a bike i’d like to have. I wonder how much it weighs with a 49 frame
Nice video
I own 2 tange frames from the late 70s/early 80s!
Gorgeous 😍
Amazing
It is beautiful
Speedvagen puts out some very light steel frame bikes in this weight range.
Emmanuel Foret yeah, I have one and it’s pretty light (I can make it lighter if I spent more money). Not that I care too much about weight, I care more about ride quality and personally love steel bikes.
There is driver limit weight for this bike?
Yasijuro... Yasujiro... same to Jack. Or was it Joe? :P
it's an older generation (ca. 90-100y/o) Japanese lad's name equivalent of Theodor, Gregory or Barnabus.
do you have a link to the b king components?
What does the bike cost?
The frameset will be around $1,600. Cheers, Jack
@@bikeradar does it rust?
Does it shift into the large ring? 🤔
Wow... a kid's bike that weighs less than a full size one... Big surprise.
When they make a decent sized frame that light, then I'll be impressed.
Not everyone is over 6 ft. Tall
@@jedisdad2265 Yes well we already have a natural weight and drag penalty so we need the faster and lighter bikes more...
@@sergarlantyrell7847 you need the aero more than the light weight. You’re going to produce a higher average wattage than a smaller rider, which will compensate for the higher weight of a larger bike. The new aero-oriented bikes are really something.
How much is it without fast forwarding to the end ?
The bike you're standing in front of looks like it would fit someone about 4' 8" tall
This frame build just screams to be offered in a fixed gear / Single Speed model.
Meantime I'm enjoying my 2010 Specialized Langster London !
What if you weigh 80kg and ride a bike that's 5kg, is it the same as having a bodyweight of 70kg and a 15kg bike?
beauty
What shoes is jack running here? Asking for a friend...
Solovair 4 eye Gibson shoes 👞 They're not SPD-compatible. Cheers, Jack
Well, 1700gr the frame in size 52 mm (yasujirobike.com) is not the lightest steel... I have a fausto coppi columbus nemo in size 55mm and its only 1580gr, and is not the lighter by far. Here maybe just talk about very interesting and super light components with a good steel frame. Its a begining
I agree, the title is kinda misleading since basically only the frame is steel, the other components are carbon/aluminum... And i have a Bernardi italian road bike frameset made in the 90s with Columbus Genius size 56 that weighs only 1690gr... Since the tubes were shorter in this yasujiro frame i was expecting a lighter frame than 1700gr, considering it's a modern tubeset and with drillings too...
@@giegue.8550 Yes, it is very curious. Today, after 20-30 years, the best steel frames are heaviers, not by far but heaviers, that the good old ones in mid late's 90's... Columbus, for instance, discontinued Genius and Nemo, and nowadays are making heavier sets, top of range, spirit and xcr, and those genius/nemo are very reliable, strong, stiff, etc. Strange...
A beautiful frame deserves a proper fork. Silly plastic isn't right.
