How Do Bicycle Gears Actually WORK?
How Do Bicycle Gears Actually WORK?
Ever wondered how bike gears and gear ratios work? What’s the difference between a standard, semi-compact and compact chainset? What gearing did Lance Armstrong use?

low gear ratios result in high mechanical advantage but smaller frequency (number of turns) and high gear rations result in low mechanical advantage but higher frequency — the total amount of energy output (i.e., work) done is the same (with higher gear ratio you are cutting up the work into smaller pieces)
Wow this video couldn’t have made it anymore more simple, I was getting so frustrated with these other tutorials. A lot of them already assumed I knew my gears and names for my gears. Thank you.
This is the answer to my questions
Armstrong could have done those climbs on 53/11😂… Though not sure he was the best example to be honest🤪
Nice channel name
Loved this, thanks!😎
Aw! We need to go back in highschool math! I hate math tho!:(
For you non doped plebs, just do what contador does. Get the cassette with 1 up front the boggest cog you usually use, so you never run out of gear. No shame to pedal 11 – 34 because contador uses 32 on mountains and hes logic is that, the biggest rear cog should rarely be used, so you never run out of gear.
My gears have a mind of their own they change about six hours after me changing the gear
4.3 is huge gear ratio.. This gearbox works like CVT
this was really helpful!
Lance Armstrong is a cheater he used stairoids
But is there ever a bike that operates using pure gear chains?
How about "How Bike Gear Ratios Work for You" This is exactly what I wanted to show my math students as we discovered and studied ratios and a real world example they could connect with and their bikes. Bravo!
Bro, Lance was on drugs! So whatever gears he was using is irrelevant.
Keeping 90+ cadence with a 23 up a 10% grade is unfathomable lol.
I prefer your Video it’s more detailed and explains how it works which was what I was looking for and this popped up very helpful ty
I HATE SCHOOL
Where did ratio came from
Hey i have on my mountain bike 7 only cassettes at the back
Too much stress. I’m going fixed
cycle max gear ratio?
I don’t like geared bikes. It’s mostly a gimick
but … but … but … you didnt really explain how gears actually work. but thanks overall. i didnt know how to calculate the wheel’s turn. how can we calculate our speed then? number of teeth on the chainring/cogs * the circumference of the wheel?
This is so much simpler to understand now. Great video.
Ok BUT you missed a great deal. First if all – road cranks traditionally come in 42/52 tooth ring clusters. Second- why presuppose all shift levers arein the brake lever on handlebar? I still use my old school road bike with down tube friction shifers pretty often. It works pretty well, and I can shift into whatever gear I want instead of only in single increments. There are still A LOT of these bikes being ridden. It is still a thing. AND you never mentioned epicyclic gearing at all. Dude- you are missing out. But I must admit that what you did cover was well done and helpful. But it is just a small part of the story.
This was more "what are gears" than "how do they work". I was hoping for a description of your shifters change the gears etc
Sir Hindi mein video Banaye
which is the fastest gear
in my cycle I have 6 in rear and 3 in front
please reply brother
Of course lance could do 450+ Watts for a sustained period.
And to this day, I still don’t know how to use the gears
ভাই কিছুই বুঝি নাই।
He was on gear to push that gear😂
oh shit mech engnrng
Please do not quote Lance Armstrong’s references in your videos.
I tried to lower the front gear going uphill and chain fell off.
No offence meant, but Lance, what’s his name, does not exist in the sport of cycling anymore. He gave, to the sport of cycling, the biggest black eye, so to speak. So let’s keep his name out of it altogether.
this how cvt works!!!! hahaha!!!!
12 speed road cassette. Hmm.
Yaar chalu Kariye Ki Pani gayi ki nahi
Very helpful and useful knowledge
What a stupid video! The title makes it look like you’d actually explain how the gears work on a bicycle – meaning how does the shifters "shift the damn chain" across the derailleurs. But you just basically named the parts and moved on. Wtf?
Fuck that druggie
Sorry for my ignorance, I’m new to cycling. But wouldn’t you want your gear ratio to be a 4.3 when going uphill so you’re not pedaling as much?
Perhaps an example of Eddy Merckx going up Alpe D’Huez on a 42:18 would be perhaps more impressive.
