Awesome video and explanation. I got here because I’m learning how to adjust and repair my rear derailleur. Awesome how you explained the invention itself. Great job.
I was much younger when I started riding. Back then, everybody used freewheels on their bikes. I still have a 13-18 6 speed block, and 7 speed 12-18, and 12-19 freewheels. When Shimano finally came out with 8 speed cassettes, I used a 12-21 for just about everything. 9 speed cassettes usually ended up with a 12-23, but I also used an 11-21 and 12-21 for flat criteriums. Finally, with 10 speed, I either use a 12-23, or more often now, a 12-25. I refuse to switch to 11 or 12 speed, because I don't need lower gears than a 39x25. I have to admit that the older I get, the more I use the 39, instead of using the big dog on everything.
in the 70s i first had a Peugeot with 52x45 and of course five speed cog. then i bought a used Cinelli fully campy. 52x 44 (also bought a 54 tooth for special events). rear hub gears normally 14-18. but for the rare hill events had up to 21 or 23 teeth (forgot which). no worries about indexing with gear shifting by hand on the tubes lol. nice video ty
I was with you, 13-23 five speed rear end for hill climbing. Italian bikes came with "Alpine" crank chainrings, 52-39. I still ride my old PX-10, now with a 7-speed 13-25 cluster on the back. Needless to say, I ride my other road bike on "hilly days"!
My 1969 Schwinn varsity had a 14-28 freewheel? When I got into " good " bikes in the late 70's 5 speed freewheel was the only option but there was always a wide range. A lot driven by touring cycling. I still have a Campagnolo grand tourismo rear derailleur. Never used, weighs about a pound, it's steel and beautiful. Have to disagree with some of your history based on my experience.
Really love your videos. This channel is underrated. Will you include climbing vs power vs cadence vs gradient. I believe most road bikes are massively overergeared for the average rider. Top riders pushing out 350 watts for 1 or two hours have a 34/32. So with a novice at 200 watts or less probably needs at least a 40 cassette to maintain reasonable cadence up the same hills. In fact I suspect our novice may need more than a 40 to maintain the same cadence as pro riders.
I would completely agree with you - the number of riders hammered by the Joux Plane in this year's Etape was painful to watch. Good Cat 1 riders were below walking pace on their 39-25's. However, I would say overgeared though, not under?
Sadly, the recreational amateur enthusiasts generally have chosen to look the part of a racer, hence riding equipment and gearing their bodies cannot manage. Tourists and distance randonneur riders have no vanity issues, often using triple cranks and customizing wide rear clusters for practicality, not cosmetics. Too bad manufacturers are still catering to appearances and style, particularly in the 1x fad that fails both in widening gear ranges (it does not, cannot without forcing gargantuan rear cogs), while widening each jump between gears.
My 1973 crane/DA first gen RD (short cage) was rated at a max of 28t, but easily handles 30t. I am still using it today with 14-19, 42 upfront. Just not in the hills. There was an equivalent crane / DA long cage from the same era rated at 34t, so I am not sure if campag won the race for large cogs / easy gears.
well said. you look around, company that spent a lot invest a lot in being inventive, they are not the at the forefront in market share. Company that invest in making it accessible to the vast majority takes the market. Yes, that's shimano.
Suntour's slant parallelogram is the greatest invention for rear derailleurs. But the old rear derailleur with a straight parallelogram isn't smooth like Suntour's. Somehow SRAM's so-called "X-Horizon" on their MTB uses a straight parallelogram but shifts smoothly like a slant parallelogram.
Was looking for your mathematics in gears but could not find it. My question is modern bikes have many speed eg 11-28 12speed vs 11-28 8speed doesn't that carry more weight with the same delivery of watts? Although I think the manufacturer here is after comfort. Less speed with same number of teeth in the ends weighs less hence more watts. What do you think? Hope you can have time.
Good question. Actually the modern high end cassettes can be lighter in 12sp than the old ones in 8 speed due to use of improved materials (eg titanium) and milling out more of the cassette body. True, a single speed (fixie / track) with 1 gear is likely more efficient (optimal chain line and tension) but it is highly inconvenient for the road. It is not really the weight but the chain efficiency that costs watts. Plus there is a physiological cost.....namely more gears mean more choices of cadence whilst keeping the torque manageable (see fft.tips/cadence) which means the metabolic efficiency is higher. alex@fft #happytraining
@@Fastfitnesstips Yow!!! Am not a pro nor a physiologist just your average less than a weekend warrior. That table added more confusion. Nevertheless was just thinking that though old heavy 8speed why not also make the new light 12speed to 8 by just lessening the cogs. Lessens the confusion on what gear I am into. My queastions to those weight winnie and you answered pros and cons big thanks.💥✌
All that has been said in this video I waiting to hear you comment on the new Sram AXS road group because there is a bad bad vibe coming from all the comments posted in all the release videos.
Utter bullshit! There were plenty of older short cage rear derailleurs that can handle much larger than a 19 tooth large cog. A old Campagnolo short cage derailleur capacity was about 26 teeth. Some people are even able to get them to work with as large as 28. I rode across the country with a 25.
He man, I like your videos but the audio makes it unwatchable. Sounds like the microphone is in the other room or something. Can you experiment a bit to improve that? itll make the experience a lot better.
Oh yeah already WAY better keep it up. I think audio quality is key. I never subscibed your channel because of the audio quality for me it was always hard to listen to, even though your talks are interesting. Since you are improving i will subscribe so i can listen to your new stuff.
@fastfitnesstips would love to learn about proper gear ratios..... I'm currently running a standard 53/39 crank with 11/27 and I want to know if I should switch to a compact gearing.

Great to see a different approach to cycling information.
Finally found a video describing this topic in depth. Cheers!

Great data,,, my 1973 Derosa still going strong with the campy set up....salutations from Mexico country
i was brought here looking for more of an early history of gearing on bicycles. i'll keep looking. cheers
Great video. Thanks for sharing... Cant wait for part 2 & 3... Cheers.
Late next week hopefully! but a couple of surprise videos coming in between
keep up the good work love the informative content
Great stuff as always, thanks!

Cyclespeed Tours Yes I meant overgeared.

Super informative. Great content.
I don't even have a bike, haven't rode one in 25 years, not since I was in high School but I found this very interesting.

@fastfitnesstips would love to see a part 2 !
I remember the Campag Rally long cage RD, never realised it's historical significance. Fascinating timeline for gear innovations
suntour!! always makes me sad the fate of that company. They used to be the best innovating :(
well said. you look around, company that spent a lot invest a lot in being inventive, they are not the at the forefront in market share. Company that invest in making it accessible to the vast majority takes the market.
Yes, that's shimano.
I still have Suntour Superbe Pro on my old PX-10. They were a big upgrade from the Simplex that came stock.
Is the electronic groupset/shifter the new standard for Tour De France road bikes?
Suntour's slant parallelogram is the greatest invention for rear derailleurs. But the old rear derailleur with a straight parallelogram isn't smooth like Suntour's. Somehow SRAM's so-called "X-Horizon" on their MTB uses a straight parallelogram but shifts smoothly like a slant parallelogram.
Hi have you published the other video you mentioned about gear ratios etc?
delayed by other projects and work sorry!!
+Fastfitnesstips you struggle to cope with a demand :) take care
I actually searched this up on the 16th of April 2021

1x14 groupset ? Probably the groupset could use a 53 T chainring and a cassette as large as the rear wheel. That's a massive range
SunTour had long-cage derailleurs in the late 1960s.

Paul de vivie invented gears
yes but I invented ice-cream with a donut on top! ;)
i ride a 2x9, never felt like i need more gears...
easier to clean mud with a 1x11
Does he want to expose or fight?
Imagine having to ride a bike with out a free wheel hub.
Fixie lol
He man, I like your videos but the audio makes it unwatchable. Sounds like the microphone is in the other room or something. Can you experiment a bit to improve that? itll make the experience a lot better.
Thanks, we are working on it; what did you think of the audio on ua-cam.com/video/28E9lzSmFvI/v-deo.html

hunh. thought ten speeds came out in the 60's.
Love this channel. You have a facebook page/instagram/twitter/strava?
Just added those links; thanks for reminder! facebook.com/healthfitnessradar/ | twitter.com/fitnessradar | www.strava.com/athletes/wattsup

Awesome! Just followed all. Keep up the good work!
As an Asian, watching science video always gives me a good high lol
...any future topics you would particularly like to see featured?
Will be nice to see a breakdown of different clipless pedal mechanism :)

CVT is better
Internal gear supremacy
