How Much Lighter? Dura-Ace vs Ultegra: Real-World Weight Test

[@amitkumar-wj8gn]

250 grams weight difference, of which a little over one-third is just in the cassette. Just get the DA cassette and save on the rest!

[@klein-concept]

I think this is a very good takeaway from this 🤜🤛

[@vladfromfrance]

Exactly.

[@kawabus]

I did this :)

[@DDai-qd8uk]

cassette and shifter clamps!

[@travispyle2905]

If you live in a flat area and never ride hills... buy your fancy cassette and switch to a 1by crank ... more weight savings as a 2by with full Durace.

[@amitkumar-wj8gn]

Thank you for this video. As someone who has just moved to a 3*9 with downtube shifters, this was very timely for me.

[@klein-concept]

🤜🤛

[@kawabus]

I have to say I do prefer the matte black of the Ultegra group. And there is a saying "Those who need Dura Ace, don't pay for Dura Ace" 🚴✨✨

[@klein-concept]

Haha very well said 🤜🤛

[@kemson4455]

Good comparison. I updated my Ultegra Di2 with following components: - Dura Ace Casette 86gr - Dura Ace Chain 10gr - Dura Ace Brake callipers 48gr. - Dura Ace Brake clamps (Titanium) 12gr. In summ. i saved 156gr. and spend around 580€. My bike weight reduced around 2%. Unfortunately I can’t feel any difference 😅

[@klein-concept]

Good choice of upgrades tho 🫶

[@madyogi6164]

Yes, cassette is amazingly lighter.

[@CHRIS_HITCHCOCK]

If losing 250grams is that important, have a dump pre ride. Even having a 250ml piss saves you that much. Guaranteed weight loss and doesn’t cost a cent.

[@klein-concept]

@@CHRIS_HITCHCOCK but imagine taking a dump AND riding the Dura Ace 😂😂

[@TheBassallyear100]

ideally buy most of the Ultegra groupset but get an Edco 12s monoblock cassette and a Cybrei or Elilee crankset. That will bring you to below the weight of the full DA groupset for just a little more than the price of the full Ultegra groupset. You lose a tad in shifting quality with the Edco cassette but it's massively offset by the weight and cost saving over DA.

[@klein-concept]

Agreed. There are also some of these lightweight components on the way 🤜🤛

[@alvinnieves590]

My setup is Ultegra, but chain being KMC, cassette from Prestacycle, brake rotors from Galfer and cranks from Rotor, all of them lighter. As a sidenote, the XTR brake rotors are lighter than the Dura Ace.

[@klein-concept]

Great setup. Smart choices on getting the best lightweight upgrades 🤜🤛

[@nikpetrov6260]

It seems weight isn't the the point of difference, rather than speed and accuracy of shifting. And that's why Shimano made their group set not entirely wireless. Because of the speed of transferring signal. They said like they beat up any Sram gs in this. So they say) But to be honest if you aren't a professional rider you will be pretty much perfect with 105 Di2)) Or Sram if you prefer frames without an option of installing Di2 stuff

[@klein-concept]

Yes for most 105 di2 will be good enough. I went for the Dura Ace purely to make it a lightweight project and not because I need it. 🤜🤛

[@markrobinson4656]

Appreciate the video and effort. Interesting to see firsthand. That said, for me, it is Ultegra everytime.

[@klein-concept]

@@markrobinson4656 lot better price performance ratio 🤜🤛

[@markrobinson4656]

Absolutely.

[@endtimeslips4660]

ultegra set plus light carbon boost slr saddle from selle italia, with light weight wheelset like ventoux evo from farsports and tpu tube far more cost effective for weight saving with all set normally i got bike weight between 7,2kilo-6.7 kilo depend the frame set used. plus if you have avian canary you save 100 gram. i put this thing on my wilier make it uci illegal.

[@klein-concept]

Oh yes that sounds like a real cool bike. Great weight achievement 🤜🤛

[@G60syncro]

I'm really leaning more towards the matte finish... As a car enthusiast when going to car shows, seeing someone pull off a flawless matte paint job deserves way more cred because if there's a blemish, there's no sanding or polishing to save you. I'm also all about understated bling... what makes everyone go "yeah cool bike man..." not realising what's actually going on.

[@klein-concept]

I have to say i think i prefer the matt finish as well even tho the gloss actually looks pretty good on the bike now. 🫶

[@G60syncro]

@@klein-concept can't wait to see that episode!! It would be cool to have a ride episode where you try out the bike but also show nice riding spots around Berlin.

Hi. You mentioned 3D printed a few times but on the Bossi website I only found "cast" and "hydroformed"... no 3D printed... Can you point to where the 3D printed part is mentioned? Thanks

[@klein-concept]

Very good point. My understanding was that casting titanium would work by 3D printing. But let me find out more 🤜🤛

[@JFomo]

The Ultegra crank was 172.5mm and the Dura ace was 170mm. Were they both compact 50-34?

[@klein-concept]

Good eyes. I completely forgot. Yes they are both 50 34 🤜🤛

[@kurtik9309]

The front derailleur wasn't worth it to me to get a Dura Ace. So I saved myself the trouble and got Ultregra. The CN-M9100 chain is great, it lasts me >10,000km. After the first cassette I switched from Ultegra to Dura Ace. When I saw that I was riding 80% on 4 sprockets. And you can replace them relatively cheaply. Plus the big difference in weight. Unfortunately the video doesn't say anything about the crank. Grading and crank length. The Ultegra shift levers don't have an additional button on top?! I weighed the same +-0.5 grams. Only the MT900 is 3 grams lighter. Greetings from Germany.

[@klein-concept]

Both cranks are sub compact so 50-34 but the Ultegra one actually is 172.5 and the Dura Ace one is 170. I think the Ultegra shifters also have a button on top. Will have a look later 🤜🤛

[@spkroadbikes]

Just get the ultegra groupset and vhain the casette to dura ace and you'll get all the weight benefits plus better shifting. If shifting is not good enough just get the rear derailleur.

[@klein-concept]

I also think that would be the smartest move. 🤜🤛

[@kemson4455]

Ever thought about to use the XTR brake discs RT-MT900 instead of the CL-900? They are 5gr. lighter each. And possibly downgrade both disks directly to 140mm for more weight saving, if you are not riding hilly roads!?

[@klein-concept]

@@kemson4455 i actually went for the galfer discs which are even lighter 🤜🤛

I like the others as well but for these two groups at the time they had the cheapest price and they arrived the next day 🫶

[@madyogi6164]

254 grams is A LOT. But $1000 is A LOT (to me) as well. Anyway, I - amateur rider - have got myself 11s Ultegra (manual) lately and I'm more than very happy about it. Do I need Dura Ace? Well, if I was 25 years younger, had no injuries (got hit by car when biking) and could easily push 300 Watts drafting across peleton, then somebody would probably buy one for me.

[@klein-concept]

I love the 11s Ultegra. Had it on one of my bikes for a while. It is more than enough. 🫶

[@madyogi6164]

@@klein-concept Ultegra was my dream, sort of "must have" doing bike upgrade. Old bike (2010) is still a mix of Tiagra 4500 and Ultegra 6500/6700 components. New one (which I've built this year) is full R8000. Said to upgrade the old dog to the same group right after I use all remaining 9s chains, which is going to be like 3-4 years maybe. I'm not in a hurry in spending money. :D Though I dream to finally sit on my new bike and have a spin!

[@klein-concept]

@@madyogi6164 Love the R8000. Real beautiful and snappy group 🤜🤛

[@GeorgeD1]

I recently swapped my Ultegra cassette for one of those one-piece lightweight Asian cassettes. Boom, -100 grams. Shifting is a tad worse than the Ultegra, but I don't really mind it, and I think that's enough for me. Being close to 80kg, chasing the last 150 grams feels unnecessarily expensive.

[@klein-concept]

Love those China cassettes. As you say they shift a little worse but they will also step up their game at some point and have comparable performance i hope.

[@G60syncro]

Like Bike Farmer says "easiest way to shed weight is to take a dump before going on a ride"

[@StonerOnLane]

Quando for fazer outra comparação de peso, retire todas partes móveis que conseguem ser trocadas por outros componentes em titânio, ou mesmo de um ultegra para um dura ace, é ai que você realmente descobre o peso real e as possibilidades de redução...

[@klein-concept]

Good idea. Thank you 🤜🤛

[@DrFlashburn]

what I'm thinking is why don't you compare these to some rim brake groupsets.

[@klein-concept]

Good idea but i guess would need to be di2 rim brakes? 🤜🤛

[@DrFlashburn]

@@klein-concept why? Mechanical is so much better. Throw away that battery weight.

[@klein-concept]

@@DrFlashburn thats true. When i will rebuild my steel rimbrake bike i will add the mechanical Dura Ace 9000 to it.

What's the weight of the cranks without the chainrings?

[@klein-concept]

Sorry but i have no idea as i already mounted them on bikes 🫶

[@jrmhng]

@@klein-concept thanks for the video anyway. I ask because there are quite a few carbon cranksets from the likes of Cyberi. A good place to save weight since it's such a big part of the groupset

[@klein-concept]

@@jrmhng good idea. Already have a carbon crankset on its way 🤜🤛

[@SamuelBlackMetalRider]

Shocked by the so small difference between 2 cranksets!! That being said, the DA looks so much better. The mat grey is boring IMO. And the cassette… the RIRO weighs 170g for 12s I think?

[@klein-concept]

Yes i was also surprised. The cassette is a 12s Neutron one 🤜🤛

@@klein-concept new brand. I’ll check it out. RIRO does 11s & 12s HG. The one I bought for my super light Cannondale SuperSix Rim brakes is 11-32 (11s) they exist in RAINBOW which is pretty awesome

[@unterwegsmitpatrick8397]

Schönes und spannendes Video! Ich mag das auch, mir solche Gedanken zu machen und mich mit den Details zu beschäftigen. Erst letztens hab ich mir ein Video zur Campagnolo Ekar 1x13 angesehen die wog 2664g ich meine mit 9-36er Kassette und hinten war nur ne 140er scheibe. Die campa bekommt man für ca.900€, die ultegra , die nur 13-15 gramm weniger wiegt für ca 1500€ und die dura ace die nochmal knapp 250g weniger wiegt für 2500€. Das macht ein Unterschied von 600€ bzw 1600€😱. Rechnet man jetzt mit einem Radfahrer, der 75kg wiegt und geht von einem Gewicht von 8,5kg für das Fahrrad aus das nachher nur 8,25kg entspricht, macht das 0,299% des Gesamtsystems aus. Ist die frage, ob 0,299% gewichtsersparnis einem die 1600€ wert sind. Würde man überschlagsmäßig davon ausgehen, daß sich das 1zu1 auf die Geschwindigkeit auswirken würde, macht das bei einem Ausgangswert von 40km/h ca.0,116 km/h aus. 😅😅😮 Wie gesagt ich liebe auch solche Details, ich glaube aber mir wäre es auch keine 600€-1600€ Wert. Bzw 1000€ in deinem expliziten Beispiel. Aber es ist und bleibt ein tolles Hobby auch über solche dinge nachzudenken 😍 die ultegra ist fur knapp 500€ mehr nochmal 250gramm leichter als die 105er Di2, da würde mir der Preis pro Gramm 2€pro gramm Gewichtsersparnis auch noch weh tun aber da könnte man ggf noch mitgehen. Bei einem absoluten Neuaufbau kann man nochmal anders darüber nachdenken. Aber falls schon gutes Material vorhanden ist (z.b. die 105er Di2) die man nachher nicht mehr nutzt wäre es ggf schade um das Geld. Ach ist das ein nettes Thema zum nachdenken 😅😅😅

[@klein-concept]

Ja ist alles spielerei. Wenn ich gerade kein leichtbauprojekt angefangen hätte, würde ich die Ultegra nehmen. Ist mehr als genug.

If you need to buy Dura-Ace, you don't need Dura-Ace. People are not buying Dura-Ace because of the weight; just as people are not buying Ferrari or Lamborghini for their speed. It is all about showing off
