The lightest steel road bike? Getting my Steel Bike below 7KG with Darimo and Extralite upgrades 

Swap out those glasses for contact lenses, easy 100 grams saving!👍

Considering the steel frame, this is crazy... I wonder how this would work on a super light carbon frame. Cranksets, chainrings and some bolts can be swapped to save some weight and also ultralight qck release axles and inner tubes can save you a few grams... but at this point I think you start to cross the line between durability and safety. Still, go for it, this is good quality underrated content

Your frame has the seatpost cutout on the back. This means that if you insert a carbon seatpost into it, your seatclamp has to be facing to the other side. It's a known problem within the bicycle mechanic scene. When you clamp a metal frame with the bolt on the slot side, it tries to force the edges into the post. Normally this is fine with aluminium posts but with carbon you HAVE to rotate the clamp so that there is no force being put DIRECTLY onto the frame slot. I've seen many issues like yours over the years and I'm sure all professional mechanics can prove me right here.

Wow this is truly inspiring 👊🏻 Will think about bringing down the weight of my bike as well… But actually thinking about a completely new build right now and will for sure check all your videos again! Thanks for all this great content ❤️ Keep up the good work…

I'm using those ridenow 32g TPU tubes on a rim brake bike for about 1000 km now. One time a was descending a hill with an average gradient of 10% for 15 minutes and when I finished the wheels were too hot to the touch and the tubes are still fine. I even had one out to check for damage and it was immaculate. It's the best upgrade for the money.

Steel is real! Very slick looking ride my friend. Looking forward to more content.

Careful with the Nail Polish Remover on carbon, it can dissolve the epoxy. For me with those low torques on the headset, I would be using carbon paste. I really like TPU tubes. What I do is use tubeless tape to add a layer between the rim and the tube. Have about 20000km on them, with no issues.

I heard if you turn your seat post clamp 180 degrees it will prevent marking or damaging carbon posts. I think the main issue is sharp steel edges clamping on super light dry carbon. Consider sanding or smoothing the inside edges of the seat tube

Hi Michael. I have been using the ride now tpu tubes for 2-3 months on my road bikes. Did a 700km ride in 5 days with them and since most of it was in the mountains there was plenty of up and down. I’ve used them on a scapin eos5 (steel frame ;) with some fulcrum xlr wheels - carbon with aluminium break surface. No problems at all. Thanks for the videos! Looking forward for the next ones. Cheers!

Great build and weight!

I’ve found that the chain is actually a large contributor to the bike weight. hollow pin cut out chains I get would give you decent weight reduction.

Still a beautiful build. I still consider this build amazing. Great job.

TPU rocks. Rim brakes rock. I been using them fine. Rim brakes on road bikes is the way it should be.

I have personally been running TPU tubes for around 2 years on a rim brake bike no issues so far. like you video's bro

Thank you guys! You rock! 💪💪💪💪💪💪💪

Regarding carbon grip compound: No on the steerer tube clamp, yes on the bar clamp. The rotational forces on the steerer clamp are minimal under normal use, and in the event of a crash we want the stem to rotate around the tube rather than rip it around or break the fork/wheel/handlebar/levers.

Looks so cool ❤‍🔥

Use MiG welder to spot weld cable ends. No caps needed. HUGE weight savings! Great build thanks for sharing.

I am currently on carbon rims and rim brakes with these TPU tubes. I haven't put much km on them, about 100 and they seem fine so far. I guess we'll see how it turns out. I enjoy your builds and you actually motivated me to start a budget build with an old steel frame I have, at some point. Keep it up!

That Kocevlo seat is like sitting on a rock in a long ride, you should wear a padded short on it.

Steel frames pinch the seat post, so it will always cause damage to carbon seat posts. I would definitely replace with titanium, similar weight but more durable and won’t suffer that damage.

Nice. This bike must go like a rocket up hill.

Maybe you should grind down the clamping area of the seatpost tube of the frame, and/or shim the back of the seatpost?

I use rim brakes with aluminium rims, and TPU tubes, never had an issue with over 20,000 Km. Do not have any mountains near me so cannot comment on descents over 1 Km. I find the rims stay far cooler than the disks, just because there is so much more surface area to dissipate the heat .

The cheapest way to save more weight get you some maxxis high road sl , light and comfortable to ride. Around 170g for 25mm paired with tpu inner tubes.

Great video als always! Was that Supacaz bartape the one that you got from Aliexpress or the original/ genuine tape?

Superglue for the loose carbon fiber strand✅ Kcnc Tiwire Titanium brake and shifter cables!

One tip is not to dispose of the old cable outers yet, so you could use them as a guide to trim the new outers to length without having to go through the whole measuring process again! PS. This is assuming your initial cable outers were an appropriate length in the first place.

I have an OG-EVKIN carbon seatpost. I always torqued it to 2nm, but it gave a creak when i went over bumps, no damage on the seatpost though. Torquing it to 4nm completely solved the creak issue. I think you are probably good to go with that 4.3nm.

If you are looking for a durable, relatively simple to maintain(all cable, manual), long lasting, durable and reasonable cheap steel-frame bike, don't aim

A built list with weights would be nice! I have my colnago tecnos (steel fork, old threaded headset and ahead adapter!) at 8,5kg without too much tweaking. I would love to go to 7kg but without too much exotic carbon.

Hi Michael, I wasn't able to see what compression plug you're currently using but maybe there are some grams to be saved there. The Tune Xpanda weighs only 7 grams (without the top cap) 😮. Love your builds!

Ive been running the ride now tubes on my rim brake supersix all summer, haven't had a single puncture or issue. I will say I live in a very flat area so not loads of heavy braking!

I have used the Ridenow TPU tubes for over 3000km on rim brakes and chinese ICAN carbon wheels. No issues whatsoever apart that they do loose air. You have to pump them up regularly.

Nice to get into the 6s!! I can't recall which wheels you are running, elite drives maybe? You could save some grams by upgrading these, expensive though! As you said, chainset you could probablt shift some weight, zrace etra light cassette as well.

Mega gut Respekt! Deine Videos inspirieren mich jedes mal aufs neue auch mein Bike zu modifizieren :) Danke! Der Carbon Sattel sieht sehr cool aus vor allem mega leicht. Kannst du den Sattel empfehlen für längere Touren (>150km) oder ist der Sattel wie ein Brett? :)

I have not had problems with TPU tubes on rim brake wheels. About 5k with 25c tyres. Hilly where I live, but 25C max and it rains a lot.

i love it

Well considering it is a risk going on the bike never mind racing it. I had my share of risky rides. I used to ride daccordi frames in my racedays.

The person that told you to hold the handle of the torque wrench is 100% correct. There is a right place to hold it. When torquing multiple clamp bolts "steering stem" you want to tighten evenly and then when one has reached the set torque, go to the next and when that one reaches the set torque, go back to the first one again. Go back and forth until they both click in your case with just the slightest of effort. Don't click one then the next and call it done, this is wrong. Not sure by the Video but looked like it. It appears as if you need to chamfer the sharp edges of you seat tube. Classic sharp edges digging into the seat post, under tightening the clamp could also cause movement that shouldn't be there. Torquing something not enough can be bad too. I would suggest you stop torquing on the low side. Put your fears aside and split the spec. I have been using CYCLAMI TPU tubes for well over 2000Mi /3200Km and no issues other than I kick myself for not trying them sooner. They have been fantastic in every way. Anyone that tells you heat is an issue is just fear mongering. Not a thing... Cyclami tubes have the more robust metal valve and not flimsy plastic like the others. Previous setup: Butyl tube for 25mm tires 74 grams 11.00 USD/ 10.32 EURO New setup: CYCLAMI TPU 36 grams 8.50 USD / 7.98EURO

What kind of mounting stand is it that you are using in the video? Looks very comfy to work on.

Jedes gesparte Gram ist es immer wert ;)

What tires are you running? Maybe there could be some weight saving too, if you swap to non tubeless clinchers.

What is that mount? I've not seen it before. I was going to get the Silica one, but I think I actually like that one better. Great job on the build too. I know the owner of a bike shop who rides a steel frame road bike. His is insanely light too. It is shocking when you pick it up knowing it is a steel frame. And he rides a 56, so it isn't like it is a 48 or a tiny frame either.

I notice your falconer helmet is quite heavy, The Abus Game changer is listed at 30 grams lighter, a true weight weenie considers every gram wether on the bike,your clothing or your tools. A friend of mine rides around with a heavy lock permanently attached to her frame, and i have never seen her use it!

Try helicopter tape on carbon clamping areas adds extra grip with less torque

Interested in the MOST bar tape, how does it feel to the touch? Happy with it?

Most is pinarellos in-house component brand but this has probably already been mentioned in the comments

What are the references of both computer mount: AFTER and BEFORE please? sick set-up and video!

I might be wrong, but I don't think you really need to keep the stem cap on at all.

Liked the video very much, would have liked a written down weight comparison to show difference. Was it above 450 grams? That would be 1 lb in the US, and I would consider that a nice gain in weight savings.

Ist es nicht schlecht für die Mechanik des Drehmomentschlüssels damit Schrauben zu lösen? Dachte immer man darf nur festziehen 🤔 Rad gefällt mir sehr sehr gut, super clean und mega interessant LG

using the ride now TPU tubes on my rear, 500kms. in with some 3-4km long steep 10-20% descents on carbon rims and they're good. i got a tubeless front tire so take it with a grain of salt.

2 Nm on stem seems fishy.. like, it's ok not to tight them too much, but how confident will you be applying force when climbing out of saddle, or, especially, when sprinting.. Bike looks superb, nonetheless.

Im so glad that my Caad 12 with cheap Chinese 1.5kg alu wheelset, lightweight 11-32 cassette and rest shimano 105 stock parts weights ~6.5 kg, no need for such expensive parts) just a light frame to begin with)

how much weight did you reduce after using jagwire elite links?

Timecode 21:46, wenn die Zunge draußen ist, ist das ein Zeichen, das die Arbeit mit voller Hingabe erledigt wird 🙏.

i bought tpu inner tubes on amazon for just 10€ and had no issues on my rim brake bike so far. they ride amating. btw what front light do u use because the light mount seems quite high quality? Great video by the way!

Are you using a torque wrench to loosen bolts?

I ride rim brakes with those aliexpress tpu tubes no problem at all

Sram Red is the key for save weight 😁

Are you still happy with the DJI Action 2?

Imagine the weight savings if dyneema brake cables were a thing.

Crankwise: SRAM Red hiddenbold 5-arm with extralite chainrings.

i'm using ride now tpu on my rim brake bike. seems to be fine. i've logged 1000 kms already.

TPU tubes always failed at the base of the valve stem for me. It's good for about a 1000 miles and all of a sudden lose all pressure. I also prefer the ride feel of butyl and latex over tpu.

Spent quite a bit of money on parts that are extremely fragile for ~100g savings. I don't know about that. Ive got my steel 1998 Lemond Zurich down to ~6.9kg for much less cost. The parts are not as fragile either. I would look into a different wheels to save the most weight.

Interesting

Do these extra light parts that require minimal torque creak a lot?

With retromods there isn’t such thing as if is worth it. A new set of tyres are more expensive than an old steel bike. It is the experience that you get, a certain satisfaction. Saying that…i need to check my early ‘80 Puch Clubman….brb after i splash some money🤣

hii. what its your opinion about that ee brakes?, they power are similar to a shimano 105?

Die TPU Schläuche ersparen fast 200 gr rotierende Masse,und ich hatte das Gefühl mein Titanium rim brake bike beschleunigt schneller! 🤙 Gruss aus Hamburg

All these super light components tend to crack and make noises. I don’t trust carbon handle bars and stems on solid bikes where forces are extremely high.

Hola, interesante video, tengo una pregunta con respecto a la potencia, ¿ Sera suficiente 1.9 Newton/metro, no se rotara cuando se cojan baches? Con respecto a la tija, yo le daría con un limatón a la zona del cuadro que marcha la tija, no mucho, lo suficiente para quitar los filos que marcan la tija.

Do you know a tick to mont a modern fork on a vintage bike ? the tube ends in a cone on the modern fork but it's the same diameter .

How much money did the work of art cost you?

If you want steel feeling bike but lighter go for titanium.

wer Bremst verliert, gilt wohl nicht nur für Tubolitos. On the Eurobike there was one Retailer with a new Tpu tube less than 18gr each.

what brand are the brakes?

What a shame that the person who told you how to hold the torque wrench didn't hell you that using it to undo bolts will mess withe the calibration. So, yeah.

Hate to break it to you but I don't think you'll be able to run that Darimo seatpost in a steel frame. A steel framebuilder warns against using carbon seatposts in steel frames for the very reason you show. The frame compresses into the carbon causing the seatpost to fail. Maybe Darimo says steel frames are ok to use with their seatposts and I hope you're able to make it work. Just passing along what I was told concerning carbon and steel. Great build and I really enjoy your content.

y doesn't look nice but put seatpost clamp with pinch bolt opposite from the slot in seat tube.. i just noticed same comment by YellowKneedMoose

That's see is hell dawn by literally a string.

Something doesn't add up. You saved like 81 grams on the saddle, 18 on the seat clamp, 13 on the stem and 15 grams on the computer mount. Are you sure the rest you swapped in is not actually heavier? 7,020 to 6,925 is not it :)

This much money in parts but no silicon extreme tape? Do you hate yourself?

racework carbon crankset maybe?

swap to extralite chainring maybe?

schönes Bike. Kannst du mir sagen welcher Lack verwendet wurde?

Are your eyelids ok?

that seat post clamp style is sketchy af

вынос UNO, руль RXL.

My pego is 6.7kg

You would have left it as it was before...🤷🤷

These New parts are for sure NOT worth the rebuilt!

I can't tell if this is a joke video or not...

Has anyone told you, you look like Stephen Miller? The Trump adviser. Apologies :(

Hello, what is a name for garmin mount you had with this double through screws?
