This is a great explanation man, keep it up! I'm partnered with Whiskey Throttled and we'd like to share some clips of yours and properly tag ya!

Awesome weekend 😎

I always welcome new ideas and anyone looking outside the box and the accepted "truths", and you certianly have some interesting ideas. But in this case I think you misinterpret the data grossly. Without knowing exactly what settings you have in the softer fork compared to the stiffer one, simply stating that because it reaches higher peak velocities and cycles through the compression stroke slower, producing a "larger area below the graph" doesn't mean it must feel stiffer. If one fork has a stiffer setting than the other, it will not only produce higher peak damping force at a lower peak velocity (depending, of course, on the exact setting and difference in stiffness), but also dissipate more energy thourghout the stroke cycle, which will, most likeyl, be shorter in duration because of smaller peak displacement of the wheel. And, IMO, one of the main reasons you've got a bad rep and no one really wants to argue with you is because you use the phrase "pressure balancing" where appropriate and where not. For example, in the end of this video, there is nothing regarding pressure balancing itself that influences whatever data you are presenting in this video. You're presenting a comparison of a stiffer and a softer fork. Both can be well pressure-balanced or not, they will still be stiffer/softer and will show response characteristics seen in those graphs (meaning, higher/lower peak velocities, longer/shorter stroke cycle periods, etc.).

I’ve watched this video many times but don’t get how did you know what changes and how much to make to each valve to essentially determine that it is now pressure balanced or at least more pressure balanced than before without putting it on a dyno or having pressure sensors in each chamber? Obviously how it feels is more important than what the dyno says as a final result but you had to initially determine what was not balanced. How did you figure that the comp adjuster required more valving or did you just assume that you’ve technically made the active valve stiffer without the crossovers so also increased the cadj to technically keep it the same balance but just overall stiffer? Any help would be great! Cheers for the dedication to keep persisting with teaching pressure balancing and dealing with all the other idiots that won’t even try to wrap their head around pressures and the difference of flow.

Very good explanation Vince

The big thumper making it sound easy, nice work. How come you pulled off?

Let the fourfiddy eat!. Get a chin mount - gives a better POV as well I reckon

that track looks awesome, Have you got a new bike?

Nice ride Vince. It would be very interesting to give some insight into your suspension set up. Kind of like your thoughts about how you felt it performed.

Where is this located? amazing

What bike you riding cuz? Sounds hearty

🙏

Hauling Azz. Crf guy got a fright haha

Are you comparing something between the two frames? Clickers, valving, preload? Looks like the left side has less compression damping?

Did you do an FFT to find the different frequencies in your telementry data?

Vince what was the difference at the handle bars in terms of feel?

Vince giving you an update on the Honda Crf shock you detailed in an earlier video. I’ve built the shock part for part used the settings you recommended. Well I’ve got to say I’m impressed with it. The ride is firm but supple stays up in the stroke nicely seams to have a great amount of damping control. Just need to ride it in a couple more different places to really get more feedback.

If you don't have enough velocity, this means the bump get transmitted to the chassis

Whats really cool to see is the velocity plots are real life force vs displacement dyno graphs. Soft fork produces 53% more units under the trace (these would be velocity units ie m/s) but all these units come later in the stroke, beyond mid stroke really. Soft fork is indeed "softer" up to the point of peak velocity but beyond that it is stiffer. The real reality is that because we hit the same bump on the same bike at the same speed we produced the same energy. The variation is in how we dissipate that energy throughout the compression stroke. Soft fork epitomises mid stroke harshness because it does all the work late in the stroke.

Nice video. The problem with stiff forks in enduro is they deflect on rocks and roots.

If you’re of the opinion that crossovers are unnecessary, what are your thoughts on digressive setups?

Is that a great big LVDT on the front? I wonder how the factory teams measure suspension movement, they must have something internal but I've never seen it.

Where were the patents filed? I can’t find either of them.

Simple, yet informative. Thank you for taking the time to make this video. I need to make a similar video with my bike and riding style. I don't hit jumps, but I assume I'm using the top 10% of my shock on the flats just as you are. I might want to adjust the sag in my front shock a bit more for my riding style (skill level) to get more performance.

you can go lighter, anyway nice idea ! still havnt seen them on MX bikes

I think we are finally getting to the heart of the matter here. Nice one.

Can you share how the closed chamber fork valves effect the system? I’m grasping these concepts but am curious how to apply. Does a stiff base valve help build pressure with the mid v? What would the common tech be surprised to hear?

Idk how people can be upset over damper hysteresis, it makes perfect sense, especially if you have any mechanical engineering knowledge.

This is the sort of stuff I spend hours trying to find, this is awesome.

Thank you!!

Vince very interesting series on pressure balancing. Why did you leave the 30x. 30 shim out of the rebound stack?

Does the CRF shock have stock valves?

That was excellent Vince cheers. Honestly you look at all these Sim tools and you got to wonder. F1 teams always have problems with correlation despite billions of dollars investment in their tools. The Adrian Newy (Red Bull) rocks up with his drawing board and helps design the quickest car on the grid. Not to mention climate models - complete and utter wank.

I should have said mills of oil not mm and when i talk about keeping it simple, just add and subtract shims (not stacks 🤦‍♂️) Utilize the shim factor to count the shims above the clamp shim. Start with a 0.10 = 1 then it goes as follows .15 = 3.38 (0.10s) .20 = 8 (0.10s) .25 = 15.8 (0.10s) .30 = 27 (0.10s) If you want to soften a stack to increase flow relative to pressure drop, reduce the overall shim count. Conversely to decrease flow relative to pressure add shims. The clamp OD can be useful too. Larger OD equals stiffer. A "stiff" adjuster stack or base valve relative to the main will delay the force build up, and make shock operate at higher internal pressures to net the same force as a well balanced damper. It will also produce significant hysteresis. Utilize the main piston/ mid valve to produce the bulk of the force via a decent pressure drop as it sees the largest portion of oil flow. Small consecutive bumps AREN'T low speed events but are actually high frequency. This requires a fast response damper which is best achieved minimizing the dampers internal pressure in particular the rebound chamber. Happy riding

when next video coming

Hi Vince.. keep these vids coming. English is not my native tounge so 50 of your views is probably from me :) Greetings from Sweden.

Do you know the port entry area for the kyb sss midvalve (24mm) if the basevalve has 66mm2 the difference between the could be calculated...

I can't thank you enough for your videos!

What is the port area in the kyb sss midvalve (24mm piston)?

Nice - You need you label and define the points on your chart, e.g. S = shim starting to open, O = fully open, S= Full Stroke or something.

Nice

❤

Great vid. We've been having this conversation as of late. Appreciate your insight.
