the pinarello, would love to do a test ride on it with on of your presenters!

[@gmivisualsjason3729]

And here's me returning to road bikes after too many years away and feeling rather happy and impressed with my Trek Domane AL2 with Claris group set... 😂

[@LosihoTTT]

Cavendish's Venge.

[@trevorhayes5414]

Yates’ Merckx. It’s just beautiful. Fell in love with that when I first started racing but could never afford it. But it was second fiddle, in my teenage fantasy money-no-option stable of bikes. There was the navy blue and orange Domex team Merckx bike (with Campy deltas. Sorry Shimano, but those deltas will forever be the best looking brakes. You couldn’t stop with them but you’d look amazing!! 😁) that was my absolute dream bike. Stunner!

[@sherab2078]

The most modern group set (assuming I could afford it). I've gotten into cycling (mostly touring/trekking) somewhat more seriously maybe 10 years ago, so I didn't really build up much sentiment for the retro stuff. Modern groups are both efficient and good-looking. Still, in GCN standards I would certainly qualify as a beginner, and I'm more than happy with low-end modern groups as well.

[@tengouku]

Dura Ace is great as long as you can afford it or you are a pro cyclist and someone sponsors it for you. As an average person I will go with the mechanical 105 :)

[@roadcyclist1]

As an average person, I will go with the Durace di2 :)

[@terra-ball]

As an average person I will take integral di2. As a poor person, I would still take 105 di2 over mechanical even if it meant I had to live on the street and eat canned beans.

[@yukiko_5051]

As an average average person i will stick to my ol' claris. Cheap, durable, and get the job done

[@tomscott4644]

I have first generation Dura Ace components on my 1977 Trek. It was my only bike I rode for 45 years until last year when the crank arm broke and it didn't feel safe any more. Still, 45 years of use isn't too bad.

[@danielhall3895]

Just replace the crank, and maybe the bottom bracket, should be as safe as it's been for you for 4 decades.

[@tomscott4644]

@@danielhall3895 I did replace the crank arm and previously replaced the bottom bracket. Had previously rebuilt it from scratch with the original components. But everything creaks and rattles and the old brakes (yes new pads) are not very good at stopping me at my current weight. A new bike with hydraulic disc brakes is so so much more confidence inspiring.

[@gcn]

45 years is great! You must really know how to look after your bikes 🙌 Do you think the bike is fixable? 👀

[@lio220]

You rode this bike for 45 years ! That's the durability of dura-ace

[@tomscott4644]

@@gcn It's fixed. I still rode it a few times this summer. Put thousands of miles on it previous couple summers. New bike feels more secure, but old one is still going. I weigh two Vingegaards, so new disc brakes help a lot.

[@gregmuon]

My first race bike when I was 15 was Dura Ace EX. It was considered third tier at the time. Everybody ran Campagnolo if they could. Sun Tour Superbe also got a lot of respect, but it cost as much or more than Campagnolo, and repair parts weren't available. 7400 was the game changer. It wasn't just the indexing. The whole groupset was higher quality and built for durability (for real). It didn't hurt that Suntour's derailleur patents had just expired, and Tullio Campagnolo passed away.

[@stevenagy7152]

Superbe Pro was much more elegant appearing but when SIS showed up, it rang the death knell for Sun Tour. I had Sun Tour and loved it but made the shift to Shimano 600(tricolor) in the early 90s.

[@jeremynorth]

I'm pleased that you mention SunTour which was the most innovative of all though tragically badly managed. Their Superbe Pro was the pinnacle of design at the time. Both Shimano and much later, Campagnolo copied their designs. Shimano's SIS was their first game changer though.

[@markdwelchforcongress4456]

I grew up in cycling (and working in bike shops) in the late 70s and early 80s. Suntour & Campy were the standards - Elegant, functional, - and repairable. Suntour competed with all of these innovations, but in a way that could be added to their previous versions - and could be worked on. I raced on Suntour for many years (then switched to Campy) and I was truly sorry to see them go. I still have a bike with Suntour and I have been able to keep it running like a champ. The decline of the competition between Suntour, Campy, Shimano, etc. has been detrimental to cycling overall - both in price and in innovation.

[@sir.chrishoy]

The patent expiring on Suntour's slant parallelogram RD in 1984, and Shimano's subsequent adoption later that year was the real turning point.

[@Maggie_n_Mitch23]

Campagnolo still the brand to beat 🚲

[@rowdml]

Greg Lemond was the first American to win a grand tour when he won the Tour de France in 1986.

[@MeFreeBee]

That is such a well known part of Tour history I can't believe there aren't more comments on this faux pas.

[@walter1081]

How could they forget Lemond???

[@dblissmn]

Yep. Has to be the most elementary error I've seen on a GCN video.

[@billkallas1762]

Didn't they say...On Shimano?

[@garethhelliwell9736]

Lemond won on Campagnolo. Si stated the first American to win on Shimano.

[@rowdml]

No mention of how influential Shimano were for braking performance? Spring assisted levers and dual pivots changed the game.

[@danielhall3895]

Suntour with Dia-Compe actually developed sprung levers with light caliper spring brakes earlier, as the response to the spongieness of aero levers, to compensate for the restricted cable path of the brake cable routed along the handle bars.

[@sugardove6075]

In 1974 as a High School student working at a bike shop I ordered a complete Durace group set and a Palo Alto Vitus tubing frame set. Still wished I had it today !

[@peteransel2715]

I love my Dura-Ace 9100, 11 speed mechanical rim brake set up. I have no doubt it could still win a pro tour stage, and it's a bargain by comparison to electronic.

[@mogglie]

I run a dura-ace 7800 set on my daily commute. It’s super. 10 speed. And absolutely flawless.

[@lio220]

The dura ace 9100 won a lot of world tour pro races in 2022, so there is no reason it couldn't win in 2023 !

I love Dura Ace. I' m in my 40th season of cycling now and used bikes with 7400, 7700 7800 and 9000 versions. I will never forget the feeling of using SIS for the first time and later on STI...it blew me away! But the best thing about Dura Ace is the perfection of manufactering. Durability and function are and have always been excellent. My current bike has Ultegra DI2, which is fine, but hey, it's not the same. Thank you for the video! I wonder how the next gen of Dura Ace will look like!

[@urbanjungle9600]

Can anyone remember Shimano Santé from the 1980s? As a boy i used to lust after that in the Madison catalogue…….carefree days

[@PhyllisBoone-sn8oi]

I loved the looks of the Sante'. I loved the white finish on the rear , and the finely etched logos. But that's as far as it went for me being a working mom and family to care for. I never had the funds to purchase the groupset, but nevertheless had a lot of fun over the years with my bicycles and now cycling on my recumbent trikes. I was able to eventually fund an Ultegra equipped bike, and rode three different versions of it. I still have a 2005 TREK Pilot 2,0 and 1989 Santana Chronos tandem equipped with Ultegra. I love the look and functionality of both versions!

[@ulrichr.487]

Oh yeah! Santè was a nice groupsets, place somewhere inbetween 600 and Dura Ace...it had a very specific, elegant look with it's white and grey coloured components. I liked it!

Rim brakes! Interesting 🤔 What is it about discs that you don't like?

[@IainBakerplus]

@@gcn extra weight and rotational mass, basically. And the supposed increase in braking efficiency is a bit of a smokescreen - the two systems are both perfectly fine. The real benefit of discs is to unlock wider rim widths, better tyre sizing, proper tubeless and lower tyre pressures. It's a shame some of those benefits can't find their way to rim brake bikes.

Factually incorrect, considering that hydraulic brakes are better, as well as electronic shifting

I've been riding Dura Ace since 1985 and still have my Trek 2000 equipped with the SIS group set. Little known feature- you can switch the SIS feature on/off by rotating a dial in the shift lever. Having said that, there is little reason to do so unless there is a severe adjustment issue with the rear derailleur.

[@danielhall3895]

Friction mode is well known on early index levers. It was a fail-safe measure just in case indexing might have been thrown off, so that you could safely shift and trim manually in an emergency on the road where indexing performance might have been thrown off.

Back in 1972 (in my early 20s) I had a bike made for me - Reynolds tubing, Suntour shifters, TA rings, Stronglight cranks, all the good stuff available here in Australia at the time. It had friction shifters on the down tube and I quickly learned to shift accurately but looked fondly at later bikes with indexed shifters. I still have that bike, now 50 years old. It's all polished up and lives in my lounge room while I'm out riding a carbon Domane with Ultegra. I sometimes wonder if I could bust out the old bike and fall back into accurate use of the old friction shifters.

[@gerrymcbride6429]

I often think the same thing. Whilst Di2 is wonderful and I really enjoy using it, I'm amazed by how versatile the human body is. I grew up in the 70s with Nuovo Record and a bar end shifter and could manage single or multi sprocket shifts with total accuracy, having said that I was only dealing with 5 gears then.

[@danielburges8176]

Put Dura-Ace 7900 mechanical on my bike as a groupset upgrade from Tiagra and it's been wonderful ever since. Better shifting, better braking and a huge weight reduction. Looked better too.

[@gcn]

Tiagra to Dura-ace ... That is a great jump to make 🙌

[@1FeetHappy]

recently gone back to friction shifters, has made setup much easyer

[@rogerphelps9939]

Yes. Using friction shifters, especially down tube, is a good skill builder.

[@EMC2Scotia]

Great video. I do recall however the early iterations of STI's were pretty bulky, heavy and very different to the standard hoods.

[@gcn]

Things have certainly got slimmer 👀

[@alvinmanalaysay839]

Nice recap on Dura Ace. My own story from 1984 involved the Index Shifting of the 7400. I had an E.G. Bates custom bicycle made from Reynolds 753 tubing with Campy Super Record specs. When the bike was nearing completion Alan Bates asked me to stop by prior to final finish. While there he asked me to try this new "thing" Shimano had come out with; he'd built a criterium bike for his son and had used the new Dura Ace 7400 index shifting setup. The radical idea of click shifting sold me and the final bike I got was Dura Ace 7400 throughout. When I returned to the USA in 1985 none of the local bike shops had seen the new setup and it was a novelty for a while. I still have that bike, still use it from time to time. The only real change I've made is swap out the strap pedals for Speedplays and I've had to replace the 7400 crank, still a very fine ride. Unique for that time was most of the cables were internally routed, even the rear derailleur cable which snakes through the down tube, under the bottom of the BB and into the right chain stay and on out to the rear derailleur.

My favourite bit of road in the world! I wonder if working on it is a joy of ruins it for these guys?

[@kevp68]

Great video. I have a fully refurbished Raleigh Road Ace, which has the Shimano 600 AX groupset on it. It is beautifully engineered & has the same tech as the Dura Ace, It was ahead of its time

[@gcn]

There is just something special about a fully restored classic! 👌 Did you do the restoration yourself?

[@jeremyemilio9378]

BRING BACK THE SILVER COMPONENTS!!

[@chubbyman6929]

Cool video, thanks. Looks like you could do with changing the cassette.

[@perwiratempur]

Nice video! Next up, do one for all the iterations of the Dogma!

[@gcn]

Nice idea! In the meantime, you may like our Pinarello documentary we made on GCN+ 👉 gcn.eu/pinarellostory

[@KenSmith-bv4si]

Cool video Si, didn't know Shimano invited indexing.

[@dblissmn]

The big thing here for my taste is the indexed gearing. I HATED as a kid having my gears slip out of position -- it put me off cycling. Had I been even a few years younger I'd have never had to encounter friction shifting. Frankly, I pretty much forgot about cycling for a long time. When I finally sprang for a modern bike in 2001 -- a hardtail mountain bike that I've mostly used as a hybrid -- it was a revelation and it put me back into cycling. The main disappointment today is the ugliness of black finishes, long derailleur cages and overly large rear cassette gears, but it's hard to argue with how well they work.

[@bahoonies]

I have a set of small flange Dura Ace hubs and a seat pin from the 1970s. They're black and I still use them today.

[@gcn]

Awesome! They made some good stuff back in the day!

[@bahoonies]

@@gcn The seat pin is on my old Harry Quinn frame which was made for me in 1973. The hubs are on my 1983 Colnago.

[@ThomasAnselmi1337]

Some could say Shimano STILL haven't quite got a power meter for Dura-Ace...still in development?

[@WhatTheFlipOfficial]

Surprised no talk of the Dura Ace 9000, that's one of the most iconic groupset, and still very relevant today. Even lighter than current gen.

[@ulrichr.487]

100 % agreed! In my opinion a really good groupset, looks great in it's silver/black finish. I still use one on one of my bikes, still works flawlessly ( mechanical version). Shifting performance is pefect.

[@WorldofColnago]

I got the 7800c (carbon) crank on my Colnago Master Lite Rabobank. It is the only carbon crank made by Shimano.

[@sillypuddystl2907]

Every new bike part that comes out is “game changer“ to GCN

[@Paganiproductions84]

The must be the marketing Gods lol lol

[@guochenggang0321]

As a matter of fact, Giro, Tour, and La Vuelta of 2023 are all won by SRAM athletes. That, in my humble opinion, is called "Domination"

[@trademark1874]

Best Dura Ace Groupset is missing!! 7800!!

[@franzkohlack8336]

Schwing!!! ❤😂

[@billkallas1762]

Still have 7700 and 7800 on my three road bikes. Still have a bunch of 7400 in my parts bin, too. I'm stuck in the past. None of my many wheels will take 11 or 12 speed. They are all 8-9-10 speed wheels. I live in a flat area, so i don't need anything more than a 25. 10 years ago, I didn't need anything more than a 23. 30 years ago, I didn't need anything more than a 21.

[@filippopogacar]

I love ShiManon
