Specialized S-Works Aethos I Dream Build I lightest Disc Roadbike I Schmolke I SRM I Aerothan I

The Aethos was developed as a bike for all the non racing riders out there. With a frame weight of only 585 grams, the total weight of the complete roadbike can be less than the 6 kilograms. The Aethos was designed for the pure joy of riding roadbikes and with this in mind, the engineering team brought out an absolute lightweight machine. We, the roadbike channel thought about tuning this beauty a little bit more and talked to the best carbon manufacturers and fanciest companies in the industry. Please enjoy our version of the lightest disc roadbike out there. Thx to Schmolke, SRM, Schwalbe and Continental for making this project happen.

Wir, der road bike channel wollten dieses Rad noch ein bisschen weiter tunen und haben und mit den besten Carbon Manufakturen und den schicksten Firmen der Branche zusammengesetzt. Bitte genießt unsere Version des leichtesten Rennrads mit Disc Bremsen. Vielen Dank an Schmolke, SRM, Schwalbe und Continental für die Hilfe zur Umsetzung dieses Projekts.

Holy Schmolkes that's a nice build.

As always: Superb video production. And my gosh these Specialized bikes are in a league of their own. Keep it up!

I miss road biking so fucking much. End of 2018 I got smashed by a car that blew a stop sign @ a 2 way stop intersection. 100mi rides, 900mi tours, was training for the dirty kanza. I don't think I'll ever trust drivers enough to ride the roads ever again, I couldn't walk or talk right for 100days and it was all brain injury. Didn't know my name for 8 hours after impact. I ride all of the very very few mtb trails near me when its dry enough but its a slushy muddy winter at the moment. I miss riding thru the city late at night Stay safe everyone and always spend more $ on lights. I was lit up 2 whites 2 reds but apparently not enough

[@PersonaN007Grata]

The best looking frame I’ve seen in awhile.

[@metubenoggin07]

First Born, as one who was inspired by a co-worker/cyclist in his 70's when I was in my forties, get into bikes! Yes, it can easily become a sick addiction sucking up quite a bit of your resources, but now in my sixties, I have zero regrets.

[@fernandosimoes6830]

A superb bike for pure fun.

[@vioseven3799]

This bike is a cheat code.

[@DrJRMCFC]

An absolute crime that this isn't available as a rim brake version

[@mazuelle]

Cooles Video. Ich habe seit ein paar Tagen ein sehr ähnlich aufgebautes Aethos S-works. Den TLO Lenker und TLO 65 Sattel, welcher übrigens gut fahrbar ist auch auf langen Touren, hatte ich bereits am vorherigen bike montiert. Die TLO Sattelstütze hab ich nun auch noch bestellt, aber nur weil die Alpinist zuviel setback hat. SRM Kurbel Vorgängermodell hab ich auch :) Sicher unnötiges tuning aber es macht Freude 😃

[@thomasshea4466]

Whoa! Love this video. I'm not a mechanic. Absolutely marvel at the precision. Thank you.

[@tabl10s]

This is how I would build it except I'd use Meilenstein's, probably a Darimo post and no PM. Bravo.

[@mitchellsteindler]

A dual sided PM adds about 30-40g. No reason to avoid them.

[@selladore]

Now imagine it with tubs, rim brakes and pressfit bb.

[@julmeissonnier]

Exactly 1270 grams for the wheeset (and doing the best to hide it is without disks!). That means almost 1.5 kg for the wheelset, I can build 990g tubular wheelset for $600... Then you don't need the fancy outageous shmolke carbon parts and can ride with a real saddle...

[@zachary14141414]

Just visited the Schmolke site, for the seatpost, stem, bars and wheels would be around $6k CAD lol let alone the groupset, frame, build cost etc. Quite the amazing but expensive dream 😁

[@tabl10s]

Schmolke bought THM. I have the same components for all four bikes sans wheels.

[@sepg5084]

I wonder how much shock and stress could this frame handle especially when driven on imperfect urban streets. Does it need to be treated like a baby?

[@guigamoretto]

This bike was really easy to assemble kzbin.infoUgkxMesz3KOGEmwmvyKQfLfrRSUXLFzfVHZA and required very few adjustments out of the box. The wheels did not require any truing/adjustments. The frame had some small scratches, but nothing major.I did replace the seat though - the seat it came with was very uncomfortable. The tires need to be re-inflated every 4-5 days, but this appears to be quite common for the narrow 700x25 tires.Overall, in my opinion, this bike looks and rides like a much more expensive bike.

[@drbrown1684]

hello I have been watching your channel for a long time even though I love what you are doing I also dream of buying even a bike I have no case I have no money to buy even a cheap bike I do not have enough money to buy I really dream of having a good roadbike case I really have no money seeing I'm doing you, I'm even more impressed because the bike you are making will be expensive and not just a bike, it 's really expensive, maybe you can give it even if it' s cheap im from philippines

Could have saved some weight by ditching the spacers and trimming the steerer tube.

[@theegg-viator4707]

Not only is a slammed stem not ideal from a functional bike fit standpoint, it’s not efficient at producing the best long term comfort to average power output potential over long rides.

[@njm3211]

Add the bottle cages, pedals and head unit and you're just shy of 6kgs.

But there is the derailleur hanger which is mounted and the mount for the front derailleur which is adding the weight

[@vincefava7929]

[@DARDKOPF]

Ist schon geiler Scheiß über Sinn und Geld braucht man glaube ich nicht reden. Entweder man hat zu viel Geld oder man fährt jeden Tag 18-20% Steigungen ansonsten kann man sich die letzten Gramm sparen. Finde sogar ein MTB sinnvoller als Leichtbau da man ja viel beschleunigt gerade bei CC Rennen und viel bergauf fährt. Rennrad ist für mich schnell fahren und da spielt das Gewicht kaum eine Rolle.

[@roadbikechannel]

Extremer Leichtbau hat natürlich immer zwei Seiten ;). Uns fasziniert das letzte Gramm aber klar: der Geldbeutel muss leiden. Für den Alltagsgebrauch ist solches Tuning sicherlich nicht nötig. Schön, wenn's gefällt! :)

Flavio Dui you’re missing the point. I’m referring to the actual weight which they avoided showing on the scale. Yes they state it’s 585 grams which is BS because the one I bought weighs 630 grams. They avoided showing the scale weight in the video because it doesn’t weigh the stated 585grams.
