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?

Yes it was a big leap, but in mountain biking a bit of a pain . Here in the uk i can kill a chain in 600 miles dur to grit. E- bike nearer 500 or even 450 at £60 a chain. When fit i do 600 mile a month which means a chain plus brake pads.....oh and cogs front and rear every 3 months. cheap, hell no! The mtb sector needs a revision!

Also categorize the drug used by Armstrong.

[@RPRIMICI]

1) Testosterone 2) EPO (Erythropoietin) - boosts hematocrit, hemoglobin so the cyclist can breath better. (However, it reduces blood flow due to increased viscosity, and increases the likelihood of thrombosis and stroke.) 3) Blood Transfusions 4) Cortizone 5) Steroids 6) Growth Hormones.

[@jamesmatheson9624]

Because I have limited knowledge of bikes I can't do this project maybe you can Gears were meant to be put on a wheel for you to exercise your arms same as a leg arm Exerciser So when you move the wheel with your arms you start at a light weight and after a certain number of turns you increase the gears strength so your arms moves a heavier weight This is how people get muscles They lift small weights and then heavy weights The advantage of wheel with gears is you don't need the weights and can put on muscles anywhere Let me know if you understand Thanks for the video

[@joecizin9357]

Being "Juiced Up", hills were easer for Armstrong, than for other riders. 😁

[@goldenultra]

I tried to lower the front gear going uphill and chain fell off.

[@theycallmeherbie]

Because you don't change during the climb, you change before. The front should rarely change, it's the back cassette that changes on the climb, that's what the tensioner is there for, no tensioner for the front crank gears so under hard gear change can bind and fall off. For a hill you should be on your smallest front gear, and your largest back gear, if it's to easy, shift up the back cassette until you can be stable but at the same time not come to a complete stop. As it becomes easier you work your way up through the cassette gears. After your in the highest rear gear you can than change the front and depending on ratios can start going through the next crank gear like the smaller crank gear, the front gear doesn't do to much, think of it like a final gear on a car, one gear that effects all the cassette gears.

My road bike rear cassette is in need of renewal (needs to be replaced) to be honest, I'm going to sort that out next week Tuesday. 😅 Btw, nice video.

[@ashkanahmadi]

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?

[@Goriaas]

well circumference of the wheel+tyre so standard road bike has a diameter of 622mm and tyre of 25mm width(about 30mm high) yes?(MTB would be 559mm for 26in 584mm for 27.5in and so on) So if we have say a 34-34 gear so a 1 to 1 climbing gear to make it easy for a ourselves Circumference is (622+30)*pi*our gear ratio so we'd travel about 2.05meters for one pedal stroke and if out top gear is 50 11 about 9.3meters in that

[@joeyslats31]

Perhaps an example of Eddy Merckx going up Alpe D'Huez on a 42:18 would be perhaps more impressive.

[@lennyappleton2840]

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?

[@nazarkandel]

Hi! It’s been 3 years, hope you’re gonna read this..The thing is that doing 4.3 is really tough since you need to give enough amount of kinetic energy to bike to cover these 4.3 rotations of wheels - for just one full pedalling. On the other hand, doing 1.3 rotations takes much less energy that you need to put into rotating your pedals, because you’re going to move less (1.3) comparing to 4.3 rotations. Hopes it helps!

[@Ellienollie]

lance Armstrong was a high cadence rider. and he also was doping

[@JesusOrtiz-xe1cy]

Does it make it go faster

[@Abhishek-150]

4.3 is huge gear ratio.. This gearbox works like CVT

[@alwaysmusiclover2760]

Very useful

[@ghu15]

very understandable

which is the fastest gear in my cycle I have 6 in rear and 3 in front

This means gears helps to decrease rotations by increasing length of rotation thats it.

[@vevasam]

Thank you for such an informative video. At 1:44 it is mentioned 1 turn of pedal results in 4.3 turns of rear wheel. Does the radius of the wheel has no impact?

[@henryangus6934]

The larger the circumference (or radius) of the wheel, the greater the distance the bike travel per turn of the pedal. As a result, speed is faster for the same cadence.

[@omniyambot9876]

@@henryangus6934 to add, to maintain conservation of power, you have to put more force the higher the distance per time traveled(speed). thus, higher torque required (stiffer pedaling)

[@joeg3741]

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.

[@brucewayne3141]

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.
