The biggest by far we’re look clipless pedals I got mine in Dec 1985 starting and sprinting in crits was so much better. Then STI or campag ergo, actually campag we’re crap at downtube indexed but the ergos were better for racing than STI as they survived crashes better and didn’t get tangled up in your musette at feeds.

Alex says, "[...prior to this, changing gears required careful control and judgement from the rider to ensure they had the exact gear that they wanted... and changing gears was a slow process and something you certainly did not want to do when you were tired or under pressure in a race situaton." While SIS, STI and Di2 are massive improvement in shifting, those of us old enough to remember using friction shifters, we'd say it was an art and became intuitive. A skill rendering a competitive advantage. Also notable, you could see when a competitor reached down to shift gears. (Or a competitor reach over to shift your gears as seen in "Breaking Away".) Hyperglide (ramped gear teeth) have made shifting so much smoother. A change that you do not mention is the switchover from freewheels to cassettes in the late 80's and 90's. Freewheels maxed out at 7 cogs? Now we have 10, 11 and even 12 speed cassettes. Climbing with a five speed 13-23 freewheel paired with a 52-42 crankset "back in the day" is a world of difference compared to today's 11-34 cassettes paired with a 50-34 crankset Loved seeing Shimano's tech developments over the years.

[@guytatler9769]

Maillard made 8 speed freewheels so it's not that they maxed out at 7, more that cassettes just improve profit margins due to compatability

Thank you for bringing back the fond memories of Shimano’s great inventions. There was a Shimano factory near my old office 20 years ago and I never had the chance of trying all the good technology they brought to us,. Yes, needless to say, Shimano is still number one to me in shifters and gears technology since I was a kid. The world would not be the same without them in the bicycle world.

[@carstenweiland7896]

If you had a single bike without SIS in the olden days, you were used to it and shifting was intuitive and automatical, as a professional where mechanics fiddled with your bike and you had to change bikes a lot it was a nightmare because everyday shifting was a bit different. There was a period where you had to get used to the shifting of the bike, SIS changed that.

[@robbchastain3036]

I agree and I would compare it to typing a letter with a manual typewriter, not even electric. You just knew you had to crisply and sharply strike the keys and you did. And same with automobiles, I rented a van a couple of years ago and the thing didn't even a knob for turning on the lights, some sensor did that for you. And yikes, not interested in that. And these days I am happily driving a sporty '97 Ford with five-speed manual and roll-up windows and lots of basic automotive tech, at least compared to now.

[@weevilinabox]

True, but friction shifting never went out of alignment.

[@carstenweiland7896]

@@weevilinabox That is also what I miss about it, but truth be told, your shifting usually has to be realligned once (a short time after you driven the first few days with it when things settled).

[@MrBJPitt]

Yeah, I had a non sis downtube bike for a long time doing courier work. It was second nature finding the right gear, plus best of all, when you got good, you simply shifted up or down 3 or 4 gears in one go based on the upcoming circumstances.

Due to the reaction between dissimilar metals, (aluminium and magnesium), these aluminium dropouts detached resulting in bent and broken axles or worse. Actually surprised they found one in ridable condition. Just wish I kept mine as an ornament and hadn't scrapped it.

Really nice video, gents, and thanks for modeling the coolest cycling threads of the era. And speaking of 7-Eleven, yesterday at work two gents parked their bikes as they did a bit of shopping and I got to talking to one when they returned--I had blocked off their bikes in a corner by parking shopping carts around them inside the front door--and when chatting with another rider, I default to the topic of favorite cycling channels and we agreed that we like GCN and Chris Horner--and that it'd be nice if Bob Roll did something again. And then he said he met Bob awhile back and there you go, racing and riding stories about a famous 7-Eleven rider. So thanks for wearing the 7-Eleven colors, Systeme-U, too--and was anyone more stylish than Laurent Fignoun at speed? He was about the coolest.

I loved seeing the KIRK. Talk about being ahead of it's time.

[@kevinmckechnie456]

For the most part, my enjoyment of a bike ride hasn't depended on the level of modern technology available. I own road bikes going back to the 70's and 80's, as well as current ones that are completely up-to-date. Once on the road I adapt to the specific bike and just pedal. Sometimes the simplicity of an older bike is more attractive than the latest high-tech offerings available today. Shimano certainly dominate the world's bicycle component market, and they've done some great things. Once Suntour's patent on the slant parallelogram derailleur expired, Shimano didn't waste any time trying to perfect their previous design. The slant parallelogram made SIS and Hyperglide work that much better. SPD pedals are something I'd give them credit for, as they're a lot more practical for most cyclists than the Look system. I think in the future there must be a completely different way of thinking about bicycle components. Adding a gear to the freewheel/cassette every few years isn't exactly a major innovation. Most of what I see happening is just a refinement of existing ways of doing things, whether it's shifting electronically or going to tubeless tires. If CeramicSpeed's drivetrain concept is ever perfected and available to cyclists, that would be a significant game changer. Or, going back a long way, what if Huret's old Duopar rear derailleur had been adopted by Shimano and became the standard? It will be interesting to see how bikes evolve this century, but no matter what you're pedaling, just enjoy the ride!

[@vomErsten]

There is that piece of tech that replaces the rear hub with a two-speed gearbox so you can get rid of the front mech without losing your range. Enabled only by today's shrunken electronics and wireless technologies. I think that's a fantastic piece of innovation right there.

[@kunarkiran]

Try making a video on campy group sets also. Since they have invited RD and FD in cycling

[@brunorosa2227]

The shy hidden star behind the curtains of all this technology must surely be the SP41 outer gear cable, with out it all but the Di2 would have been impossible. SP41 isn't a wound outer cable it's straight wires that resist compression allowing accurate indexing of where the inner cable will be at any moment. Fabulous thinking.

[@kalenderquantentunnel9411]

I used a bike with a six-speed non-indexed, non-hyperglide cassette for my daily commute until 2000 and i still release power when shifting almost completely untill the chain stops rattling from one gear to the next. Can't get rid of this old habbit. But I have to say that the twisted teeth of the Uniglide SIS-cassetes made for a bigger improvement than Hyperglide. With those you just moved the shifting lever until you felt the chain jumping over and you wre done, even without indexed levers. With hyperglide you also could do this with power on the pedal but the SIS-cassette to me was a bigger improvement. And btw. you could mix your own cassettes with ease as there were no fixed and bolted combinations of sprockets. I really was a bit disappointed when hyperglide replaced the more flexible Uniglide-system as I felt Hyperglide was a thing more target towards mointainbiking.

This was early 80’s and for standard, every day bikes. You pulled the leaver for an easier gear and pushed it up for a harder gear. Those were the days😂

[@randellgribben9772]

yup..i had one...modded the bike to take drop bars and brake levers.. but the 3 speed shifter stayed on top of the bars.next to the stem

[@marcelosuetam]

Awesome video! It's really hard to think now what was to shift gears taking our hands off the handle bars... and I didn't knew about hyper glide. Great work, guys! Cheers!

[@SioLazer]

I have Suntour on a vinty Allez and it also has the friction optional setting. I firmly believe that if you haven't trained on a bike with downtube shifters you're missing out. It really tests your dexterity and stability being able to move those shifters at high speed when you're fatigued.

Just saw a 13 Minute Shimano Comemrcial, when is the video starting?

[@chrisbliss2034]

Great presentation. Hopefully a future one might cover Shimano's equally impressive innovation in hub gears. The freewheel (-- c. 1896?) must rank as one of cyclings greatest leaps, though I don't think Shimano got there first. 😊🚴

[@jefferycampbell2243]

Cool, I've bought 4 new bikes over the years and can't make myself part with any of them. It turns out that my "collection" has each one of the iconic group sets: Sante (SIS), XTR (hyper glide), Ultegra STI, and Ultegra DI2.

[@DPS-Runner_Cyclist]

I do recall the days of down tube shifters and friction shifting-to Ollie and Alex they are archaic features! I must be getting old!

[@jochem1986]

So does this video being released now mean that 12 speed DA is near?

[@a.sarmiento5116]

Those power meters are the ones where pros sometimes cannot do without. Still have to wait for those electronic/digital brakes though.

[@TheGreatDigitalism]

This is really cool my dudes!

[@fluffy1973]

Having built several bikes over the last 31 years I've seen quite a bit. I always had a love hate relationship with Shimano but I have to admit their high end stuff i.e. XTR, Dura Ace is so well engineered that shifting, riding and most importantly servicing them is effortless. My only beef with Shimano is the fact that their modern hubs can change endcaps to adapt hub spacing or types...

[@bicyclist2]

How about Campagnolo now. All the TdF winners before Lance won on Campy components. I started out in the late 80's with the SIS. I two road bikes, one with mostly Dura Ace 7700 and another with Dura Ace SL 7800. I have yet to ride Di2.

4:32 Home and Away on GCN? OK, maybe now I've seen everything...

[@ygtcbee23]

Always wondered why cassette theeth are uneven! Thanks GCN

[@curtvaughan2836]

Thank you for this! I owned bicycles like these back in the day. The Gintane reminded me of my Raleigh 753 from 1989 - Reynolds 753 frame, Shimano DuraAce SiS. My grandson now rides that bike as a retro enthusiast.

[@petergiourelas3753]

Still riding 86 motioncraft 105 groupset biopace crank, still smooth, love it

[@tomreingold4024]

I think two of Shimano’s best inventions are the cassette hub and the SPD cleat system.

[@geoffthomson6602]

I thought that was great as well, our cycling CDN hero and the reason I got into biking in the 1980's

[@eyelovelil]

Awesome presentation 👍🏽 enjoyed every minute. Straight to point, just enough information to inform & leave me wanting more. I have got to catch Up.

[@geeache1891]

Dat sti eddy merckx stuur is behoorlijk begaaid over de jaren.

[@layton3503]

I want you to know, I paused the video at 6:30 to take time, to go to may Garage and appreciate my cassette, by lovingly gazing at it, I went back at 9:00 to do the same for my STI shifters.

[@JMcLeodKC711]

@5:18.....my knees blew out just looking at that.
