I'm in the process of learning about my new bike that has a back air shock, and find this vid very useful in conjunction with the video on progression. Really great material and will try to think about this when I set my bike up for different terrain conditions.

This guy should make Algebra 1 tutorials. With transition slides like that, he could amass a following among pre-adolescent males in no time.

LOL I was still listening at 5:20 - excellent in depth video, thanks

Nice job keeping us engaged with the leverage ratio.

Thank you so much for these videos. I have been looking more a long time for a resource that provides a simple but comprehensive explanation of suspension behavior.

Super helpful video, if only i could find this video before i purchase my new bike!

Thanks for a Great Explanation of the MTB Suspension! Absolutely Helped me a Lot! The drawings & examples where what I needed to understand! Awesome!

That s how youtube should be...this is so precise and instructive...total opposite of the youtuber generation

Thank you very much Andre to understand everything and being now able to pick up all the time the right rear shock.

This is awesome! Totally geeking out on this right now

Thank u for all yr effort in such easy video to learn. And not only this video.., u deserve more subscriber.

Great video Very informative Looking forward to more videos

Most instructive video I have ever seen !

Thanks for these great in depth videos.

Excellent stuff. Thank you.

Very good educational video and need more views

all these vids are amazing, you have a knack for explaining and showing things in a way that's easy to understand. If possible it would be great to take a look at the Propain mountain bike suspension design. Thanks for the great work

thanks for the details in the explanation!

Parabéns pela iniciativa André ! Ando de DH e nota -se como esse conteúdo é escasso pela internet. Com certeza será muito útil para diversos ciclistas .. Abs

geeking out here. finally know how rear shocks work

Very interesting stuff, I've been looking for videos going into more detail about the suspension. Just bought you a beer, enjoy!

So Good! Thank you

Very geeky, love it!

love your videos!

Best leverage ratio on a hardtail ever. Great stuff, thank you for your time.

Please do more videos! I absolutely love these!!!

Thank you for the these great stuffs you've been doin' \m/

Thanks you, Alextr. Nice vids

Totally not what I came here for, wanted to learn difference between rebound and compression & set up but found this downright awesome. Hope the rest of these videos are just as good. Wow.

VERY VERY nice leverage ratio

Serious knowledge, thnaks for sharing!:)

Great video! Obrigado!

Good Job! Thanks!

Very helpful!

Nice videos, with a good and simple explanation. Could you analyse the Kona coiler suspension? Thanks

I love when you say "leverage ratio"

Great collection of very inforamtive videos, many thanks!! Air shock offer much more resistance to initial movemente, meaning they are stiffer, less sensitive in the initial part of the travel. This is also an add-on modification to the LR curve, right?

Wow I’ve never seen such a nice leverage ratio

Hi, your videos are really good... At the end of the video u mentioned if the bike is progressive then placing a coil shocx will b progressive but not support progressive compared to air. Is there a big difference?

thank you very much!

These are really great videos, but you should run the audio through a high pass and/or compressor to knock down the plosives.

your a monster ty

Hey there, I know this is an older video, but I was hoping you might be able to tell me what CAD program was used to demonstrate the leverage ratio. Also, what an amazing library you have to educate people about full suspension bikes. Cheers!

hahahaahaha loved it man! Keep them coming!

Have watching your vídeos for a while and I think very nice, very elucidative. Nice job! A question about the informations on this video. How I can find the instantaneous leverage ratio from initial and end stroke as you mention on video?

Muito interessante sem dúvida. És o gajo ideal para perguntar sobre a Pitch já que tens uma. No caso de querer fazer futuro upgrade no amortecedor o que devo procurar? Pequeno volume sem piggyback tal como o X-Fusion de origem?

really like your vids, do you have any background other than biking though? cheers from rocky Tromsoe, Norway.

Great video, I learned a lot from you videos man! Can I ask you what type of suspension is my bike (progresive, regressive or linear) the bike is DaBomb Castle Bravo 2009, i can't fine anything about this bike :(

What are all the design calculations required to design the front telescopic fork and rear monoshock suspension. Since we are designing a street chopper type bike .

Do you have a video that shows and explains the various frame designs and what kind of leverage each frame design is?

po mano tu explicou muito bem. O ep. 2 seria o "forces & SAG"? Aguardo sua resposta, abraço!

👏🏼🙌👌

Very helpful, thank you for that. I saw all your vid's and did not find anything about for example the Commencal (Supreme) DH V3. Do you have some facts and information about that? Thanks in advance

Hi Andre, could you help to find out is Canyon Spectral 2018 27.5 is a R/L/P?

hey Andre, Got one question: >>At the begining of video there was analysis of one particular bike, and from dividing his rear wheel travel with shock stroke we get 2,5 average Leverage ratio, which means that for every 2.5cm of rear wheel travel the shock will compress 1cm. For that bike at the beginning of the video you said that at the beginning of shock travel his rear wheel needs to travel 3cm for 1cm of his shock compression, and when we are closing to the top/end of the shock travel we need less rear wheel travel for the same 1cm shock compression (at the top/end of shock travel we need 2cm of rear wheel travel for 1cm of shock compression) and so in that particular case you said it that is a progressive bike. So, about that, i'm a little confused. If you need higher LR at the beginning of the shock travel and less LR at the top/end of shock travel, isnt that Regressive type of progressivity ('cause at the end of the shock travel we need to make less force to the rear wheel and, because of that, it will be easier to bottom-out? ) Maybe i didn't understood nicely the whole thing so can explain me ? p.s. hope you can understand what i'm trying to ask. somehow the beginning part of video and the part of video after that girl picture (when you showing those three progressivity diagrams) are contradicted with each other, or maybe that contradiction is just in my head...

My rear wheel has also downward travel from its initial position...is it normal? If not, what to do about this?

Do you know the Rocky Mountain ETSX 10? (From the 90's). Is that one a progressive suspension?

How do I determine if my particular bike has a Regressive, Linear, or Progressive rear suspension ? I am riding a 2014 Giant Trance1 29er, do you know type (R,L,P) rear suspension this bike has ? Very NICE Leverage Ratio @ 5:30 (I was listening) :).

I was a little confused with the equation "rear suspesion = shock/LR", I'm guessing "rear suspension" means the force required from the ground to move the rear wheel? My casual bike terminology makes me view "rear shock", "shock", "rear suspension" all as the same thing

Can I install a longer rear shocks? stock shock measures 6.5 inches i2i and want to try installing a 7.5 What are the effects on geometry and travel with 120mm front suspension. Ride is only for XC and light trail.

Hi Thank you for that. Would you be able to get a Giant Trance 27.5 analised?? thank you!

Hi, what computer programme did you use in your leverage ratio explenation?

Awesome ! Can you please tell me name of the software?

Which simulation software is which you use ?

hi there, may i ask i have 190mm eye to eye rear shocks can i replace it with a 200mm eye to eye rear shock.

What is your opinion about the Scott Ransom 10?

on wh software u r doing these calculations

Is this software available for mac as well?

so how about MTB Progressive Springs vs linear springs.....can't find any explanations

Yeah great thanks for the video. Get in contact with very famous German Freeride Magazin. They need some support as their tests get more and more unprofessional. Your knowledge would help those clowns to appear a bit more professional.

Could you please add English subtitles? I am deaf and would like to benefit from a video like this. (The auto-generated subtitles are no good- try it for yourself)

Thank you I will confirm that. the bike has almost zero small sensitivity and blow all it's travel relatively easy. that's the reason why I'm asking! Cheers my friend!

I had Specialized Big Hit similar to yours. However I felt it is overkill, as I cannot ride it at its maximum an it felt heavy and hard for pedaling for my style of riding. So I sold it and bought a local brand 160/160 enduro bike with high-end parts. It definately feels easier for pedaling, however I have noticed an annoying bug/feature- when the rear end compresses too hard my gears switch and then return to normal. I checked the cables- they look ok. Probably it is matter of anti-squat which causes chain movements that were not present with the Big Hit. Can you help me assess the geometry as there is no info for this model?

5:28 hahaha

garm

Nice tutorial, but what's with the creepy perving? You want to know why more women don't do mountain biking? This kind of shit is why.
