For the first time I finally understand the gears on a bike; not only what's happening to the human body but the clear physics of the movement of the chain ! Thank you sir !
What the fuck did you say about your mama
I love this video, it's so great to see GCN providing information for those who are just starting out bike riding. We were all beginners once and it's brilliant that the crew is making new people feel welcome.
man not even beginners to biking, i used this to explain to myself how bike gears worked for a school assignment and it helped me alot
Would be helpful for a beginner to explain more what gear number to start in, when and how often to change etc - or more practical as well as the theory of how it works
There was a recommended video at the end titled how and when to change gears
I was thinking that also, but now that Javian has pointed it out, that's okay. I somehow missed that last bit.
@@oleggorky906 lol glad i could help
@@javianbrown8627 smart ass
Whatever gear you can comfortably start it.
The video photography is amazing! This closeup of the cassette is an absolute dream!
Videography or camera work are the words you're looking for but you're bang on. That's some sexy bike porn right there.
I was thinking the same exact thing
How to take same pics
Tip 1 : buy a cycle
Tip 2 : buy a camera
Tip 3 : give it to him
Tip 4 : hurry and thank me for tip( 😄😄😄)
@@shooteramv1698 xD
Suggestion: "How to understand gear ratio" or "How to undestand bike geometry". in terms of numbers
Gear ratios are simple, divide the chain ring by the teeth on the cassette and that will tell you how many times your wheel spins per single revolution of the crank. Ex a 50 tooth chain ring spinning a 10 tooth cassette. 50/10=5 revolutions of the wheel per 1 revolution of the crank :). Hope that helps. Someone correct me if I'm wrong as well.
How do the brakes work? How do the wheel turn?
good ideas! will see what we can do!
@@jussa101 That is a pretty easy concept (equation) for people to understand once explained. I think the question people struggle with, and probably what Francis is referring to, is why different ratios are easier or harder. Even more so, I think a lot of people get tripped up to why on a multi-chain ring bike the bigger gear in the front is the hardest while the smallest on the back is the hardest.
Not looking for you to explain here btw, I already know why. I just think this concept is the video most people actually need to see.
The 1:1 example is literally a gear ratio explanation, 1 rotation on the pedal means 1 rotation on the wheel.
Let say the ratio is 1:2 means, 1 pedal rotation will spin your backwheel 2 full rotations but with a little more effort than 1:1.
Why harder you might ask? It's the law of nature... I mean you should understand basic physics in this one. You can't simply go faster with the same effort.
Why gearing is important you might ask? Every cyclist is different, some prefer higher rpm when pedalling. NOT JUST THAT, it's essential for energy saving when riding. You don't want to passing out before you reach the top aren't you? 😙 that's why save your legs even if you're slow. You gotta train to be fast.
Hope it helps
Just ordered my first bike. It has 1x10 gears. Watching your video is very helpful to an complete beginner to cycling. Ps. Where I live is very hilly on the roads, and has lists of woods around a for trails. So bought a hybrid on the recommendation of the sales guys.
Please keep making simple beginner videos, so we can learn, keep motivated , and understand what we’re buying and if it suits or needs.
I have ridden for years. Have changed mine and my pals cassettes/chains again and again but It's great to see a ABC of the how the system works.
I feel like I've just watched Bicycle Story Time with Ollie. And it was excellent. And next time, I'll watch with milk and cookies. But seriously, Ollie, I very much appreciate a clear explanation such as yours in this presentation.
Robb Chastain cookies 🍪 are there cookies and milk 🥛🤷🏼♂️😂
@@LaughingSaint66 Thanks, now all I need to do is pull up a piece of the rug :)
Sorry if the simplicity of the subject matter (as evidenced by the snarky comments) didn't appeal to some, but I appreciated this video. I've been riding about a year and half and I didn't really have my head around the gear ratios and exactly what makes the gears easier or harder. Now I do. Thanks Ollie and GCN...
Very helpful, my kids are using geared bikes now and this is useful for them to understand the principles. Thanks 👍
Indeed - I'll be showing this to my girls!
Very good content! The information is super accessible, the terms were technical but not too fast paced, and it's very comfortably presented! I wish content this user friendly was available when I was getting to know cycling.
I want to thank you for some real informative, clear and great produced content. Actually made my day much easier
This was a fantastic video, thank you! Quite informative paired with the visuals, it was very helpful as I had no clue about what cassettes and how they work.
Please more clips like these! Absolutely brilliant!
Ollie couldn’t sound less like he wants to be doing this video 😂 love it
I finally understand gear ratios! Thanks, Ollie.
Excellent content Ollie and props to the camera crew. Great info every cyclist should know.
I was wondering how bicycle gears work, now I know - Thank you! I have given this video a thumbs up and now i'm off to share it with my mates.
This is exactly what im looking for!! Thank you for the video!!! 👍👍👍
thanks, Ollie. I finally know how to interpret gear ratio data!
You been fantastic in explaining this concept in the most simple manner!!
Very clear and informative video, thanks for uploading!
Awesome!!! I have been finding it difficult to explain how to change gears to my club members. This video killed it!!
Next step, ratios and how to mix cassettes and chain rings. Compact vs. standard. Why 11/28 vs. 11/32. When you can’t use a 42, etc.
This video has been really informative. Thanks a lot for sharing this!
Thanks, I'm new to biking and this explained it well.
This was an extremely helpful and clear video. Thanks
Love the close up, slow mo works guys! Great camera work 👍
Wow, this is extremely helpful. Thank you.
This video is great! My chain keeps coming off and I just try to shove it back on any cog but it’s only today I’ve sat down to try and understand the mechanisms involved. Was not expecting such a professional video. Thanks very much.
You got no chain little man you got a wire
Fantastic video. Easy to follow. Really appreciate your clear and calm voice. Made it easy to follow especially with the illustrations. Thanks.
nice, simple explanations here. If You want to dive deeper into this, maybe you could give some info and illustration on chain line tuning (from above) or minimum radius influence on efficiency (and why extreme gears are bad). I remember how I looked at the guy who sold me my first new roadbike when he explained to me that some gears should not be used...
Great video! Really learned a lot about bikes. Thank you, sir!
Easy to understand explanation, thank you!
I knew before the video how gears work but is funny see Ollie explain a thing who nearly everyone know how it work. Well done ollie!
Hello there. I found this video very helpful. You explained the basics very clearly. Thank you.
Thank you for explaining this in an easy way.
Wow! Best explanation I’ve ever seen. Thanks.
Very nicely explained. Short and crisp. Well done !
i literally found this video useful and informative, thanks !
Thanks. Super easy explanation for newbies.
Found this really helpful as a beginner because there are not many cycling channels that explain how to properly shift gears.
Thank you for the simple explanation
Finally a clear informative video. Thank you
This was amazingly helpful. Could you please do a video on what the different gear combos are called?
Like, if people ask, "Oh, what gear are you in?" How would I respond?
This video is so clear and so easy to understand, excellent graphics and narration
This is well explained thank you
A really simple explanation for newbies like me. Thanks :)
Scrub
I am learning a lot from this channel. Thank you so much.
The slower pace of this explanation compared to other videos helped my thick brain understand this 🤓 Thanks!
i needed this for an assignment due tmr and it had a question about gears and this helped soooooooooooooooooooooooooo much!!! thanks!!!!!!
Thanks for explaining in simple terms!
Very simple, straight to the point A+
Learned something new today about my road bike, gracias!
Thanks, Bro because I don't know how to use gear in a bicycle than whenm I SAW THIS VIDEO IT WAS EASY TO UNDERSTAND IT THANKYOU
Perfect. Don't know how I made it this far not understanding this, but I'm sure glad I stopped by!
This is very helpful, thank you
Very clear explanation , thank you
You explanation is much easier to understand than any other videos i've watched
Excellent video 👍
Good information for me as a beginner
Very well explained thank you.
Very useful each word worth listening
Very patient and well paced. Good stuff.
Great video. Thank you. 💕💕
Very well explained ! Awesome !
Thanks bro, I had understand the consept of bicycle gear.
Love all the vids
Oh! I was so pleased to see this. Great explanation and clear photography UNTIL the talk of pulling "up" the sprocket while showing the rear mech going into a lower gear and then "to shift back down" showing it going into a higher gear. I had hoped to share this video with the permanently confused but I think it might make things worse.
The lower gears tighten the cable and the bike naturally wants to release into a taller gear ration (smaller cog at the back). On the front derailleur, it naturally wants to release into the small chainring also, which is a lower gear this time. A bike with slack cables will shift into the small-small combination. I'm with you on the "change down" and going into a faster gear being confusing to newbies.
Thanks for this great video!
Thank you for the useful information
I hated going up hills as a kid and now I know why… I thought the higher the gear the easier it would be. Things I wish I knew before I was 30. Just bought a new bike and I’m ready to tackle those hills!
Great job and lucid explanation.
Loved it thank you so much!
Fantastically explained, I appreciated the slow explanation.
thank you so much man
thos video was very helpful
Very well explained Ollie.
Weldon bro, good information
Love the animation , easy to understand
Indeed, the animation at the end really helps the thought process.
That's for the explanation on the great ratios 👍
Well explained. Thanks
Very Informative video ❤
Explained well. TY 🚲👍
very nicely done !
This is very helpful.. thanks dude
Very informative keep and good videos and explanations
I think I finally understand how this works, thank you!
Nicely done, easy to appear patronising with this sort of instructional video when presented by an ex pro, but Oli avoided doing this. That great, because once my grandchildren get their first geared bike, this video will be most useful. Nice clean chainset by the way! New or well loved? 😃
It was the teeniest bit patronising though wasn’t it.
@@robcollinson9508 I didn't perceive it as patronising at all. How gears work might be obvious to those who have used gears like this before but not so for someone who might never have encountered a geared bike. There are plenty of adults out there, or young kids, whose only experience with bikes is on kids bikes with no gears who have now looking at buying or have recently bought bikes with gears and need this explanation.
@@robcollinson9508 wasn't intended to be. It's not aimed at someone who already knows how they work!
I'd be interested to see a comparison of how Di2 and Campy EPS electronic rear derailleurs work. They look like they might be based on slighty different electromechanical principles.
Explained well brother ❤
Very informative!
Very nice explanation
Now that bikes are a thing during this pandemic, this video really helps out.
Thanks for the video Ollie! If you could talk about how to choose tires and what features are best. Also the nutrition cyclists could follow for healthy weight. Maybe interviews with team nutritionist for the teams and cooks. And how to prepare foods for cycling.
Very good thanks for video
Finally an effective and simple tutorial
this is very helpful to me
Excellent video guys
Can you do a video on how different crank arms lengths affect the gear ratio. I just went from a 172.5 to 170 mm crank arm and definitely prefer it. Thanks
Crank length does not affect the gear ratio. The GR is found by dividing the number of teeth on the chainring in the front by the number of teeth on the cassette sprocket in the back, e.g. 50/11= 4.55 (rounded).
Explained well👍
This video's are class 👍
