How cartridge front forks work | Offroad Engineered

In this video, you can learn how an open-cartridge front fork works, its components and their functions, and how adjusting low-speed damping and high-speed damping works!
Hopefully, it will help you understand how your bike's forks work and how the adjustment of the clickers affects their performance.

Your ability to transfer complex principles into fairly simple mind pictures is the BEST I’ve ever seen. Usually when someone is sharing knowledge of such value they want to make sure that you understand how smart they are by using terminology that if your not an engineer you only get a small amount of value from the time you spend watching. You my friend are an artist at conveying every aspect in a absorbable way!!! Thank You and GOD BLESS YOU!👍😁❤️

My wrist thank you so much, I have low/high speed compression settings, and high/low speed settings on my fork, now I understand why when I adjust the low speed compression to minimum dampening, the high speed compression nearly never is "active" because it does the opposit of what is eplained at 9:58, again, you are amazing man .

Now you do! Knowledge is power 😁 They simply bend. Since they are really thin, they easily bend but don't get permanently deformed. Regarding the electronic adjustability, it can depend a lot from manufacturer, but yeah, it's a option having that!

HI matey, a number of people want to make DIY high pressure compressors (4000psi/200 bar) for paintball guns- People are discussing the idea of using motorbike forks to do it - they look meaty enough. Do you know what pressures they are designed to handle? And do you have any suggestions or interest in looking into it... it would be a very popular video I reckon. I might try myself, but need to know the pressure tolerances of forks, plus I don't have a lathe and am worried about getting stuck 99% of the way through the process. With a proper air filter/dryer these could be used to fill diving bottle, too (reserve air source for filling paintball guns). Any help or ideas gratefully received!

Can we use twin telescopic suspension in front forks??

[@StepstoPodium]

You probably can!

[@felixwilde2551]

hey i've got a question at 4:38 - if the piston-rod comes down an compresses the oil in zone B, there are two possibilities for the oil to go out of this zone: 1. the compression base valve and 2. through the check valve of the piston. Both ways can be taken to reduce the pressure in zone B. What I don't understand is that if the oil goes through the piston check valve (2.) there is not much resistance to the oil because this valve is very big. So why should be there any kind of damping?

[@StepstoPodium]

That is a great question! What happens is that only the volume in oil of the piston rod entering the cartridge is pushed through the base valve, the rest goes through the piston rod check valve (in this case, usually there is always a mid speed valve, but to simplify I just made a check valve)

[@caty863]

I can see the telescopic fork suspension is just a strut where the coil spring is inside the shock absorber instead of the latter being inside the coil spring. Any reason such an "inverted strut" can't be used on cars?

[@StepstoPodium]

It all comes down to space. There's no room!

[@ibnuhajarulinnuha6288]

[@StepstoPodium]

Which rebound spring?

[@250txc]

5:39 -- Look at the far right pic... It shows that thick washer on the upper side of the piston moving upwards to allow oil to flow upwards through the piston... Is that top nut on the compression valve suppose to be left loose in order for that thick flat washer to compress that spring and open up allowing oil flow? -- The spring and washer I'm referring to are at 2:52 on the left side. These parts are on my compression valve ... The nut I am using here is clamped down and will not allow the thick washer to move any.

[@ab7830]

Hi - can somebody who knows how dampers work answer the following please? Trying to learn but I've watched the video 3 times and am confused. Surely damping cannot actually work as illustrated/described? I can see 2 fundamental problems: 1) Taking the compression stroke as an example: as forks compress the piston sweeps down the damper. As a result, chamber A gets bigger and chamber B smaller - BY EXACTLY THE SAME VOLUME. It really doesn't matter which orifice/s any resulting oil exchange occurs through, but the fact is that chamber A can ONLY exchange oil with chamber B - so A takes the FULL amount of oil (displaced during the stroke) from chamber B. The oil exchange of chambers A/B is therefore "complete" and "fully accounted for" (and the pressures in chambers A/B will be balanced). There can therefore be no possibility for any oil to additionally pass from B to C as described. If this were to actually happen, B would then be exhausting more oil than A was in-taking (which is physically impossible). 2) The 2nd issue is with the explanation of back-filling of chamber A during compression stroke. At 4:35 the author explains that during compression, the rebound check valve opens in order to fill chamber A. Why would it do that???? Oil would surely take the path of least resistance and simply flow up the "needle metered oil passageway" into chamber A instead? Both of the same problems apply equally to the rebound stroke as well. Any thoughts??? Thx.

[@redtobertshateshandles]

It makes me laugh when some of these complicated forks don't work as well as simple old-fashioned damper rod forks. But you explained why cartridge forks are so harsh on small square edged bumps. They can't tell the difference between a jump or a small square edged bump. This is where electronic suspension will be great. Bring it on.

[@vloggeryt2189]

What happened when fork oil level gose low

It can enter air imto the cartridge and at that point, it's the same as not having hidraulic damping at all!

Nice educational video, but you ruined it with the annoying background music. I couldn't take it for more than a minute. Why do people feel compelled to add crappy music while they are talking to the world? You are what we clicked on - not the music!

thank you! I feel ya! But with fact, people can't argue, and it's proven that for the large majority of people it's easier to watch a video if it has a background music... Trust me, it would save me a lot of time looking of soundtracks to put on the vids xD Cheers nonetheless!
