I´m just getting back into the matter, just got myself a new bike and your tech videos are always a good opportunity to reflect my own antiquated knowledge (wtf im only 37) in order to fill up the gaps.

@Henry, one thing to note is that the addition of a negative spring helps overcome the preload in a positive air system. It is not to overcome stiction as you mentioned.

Great video with very good technical explanations, figures and real cut-off views. Could you explain in a video the different rear suspension geometries and above all the difference between suspension systems mounting the rear shock vertically and horizontally/diagonally please? Keep on doing such a good job! Regards.

You can use 2 rubber bands on the shock: after full compression, the first band will indicate your max travel and the second band will show your sag.

It would be good if you went 1 step further and show how to step up out on the dirt and how to fix some bad handling problems

One thing with the negative air chamber. They can't produce more than a vacuum to counterbalance. So roughly 14.5 PSI.

@dylan-5287

Жыл бұрын

The negative chamber isn't under a vacuum, it's just opposing the positive chamber but they're both under positive pressure. You can customize the negative chamber in some forks and it's usually around 20-80psi. A vacuum would actually have the opposite effect and make it even more stiff, it would be like adding to the positive chamber.

The "architecture" portion of this video, starting at 9:00, was the most helpful section. I suggest re-making the video by putting the architecture section first, then the rest of the vocabulary explanation I think would make more sense.

I would watch

I run an ohlins rear shock but it keeps bottom out and loosing air. My question is what are the ideal personal weights for rear shock, would a larger rider like me 110kg benefit from a coil or spacers in my rear shock cheers

I have a question about my specialized enduro comp 2020. I'm looking at swapping my rear shock from the select + to an ultimate but I can't find a shock that has the stanchion eyelid the right way. So can you just release the pressure and turn it?

I'll listen to more

What does switching from Imperial to Metric have to do with bushing overlap and stiffness??

@spuddo123

@@clarkie005 late reply, but actually that's incorrect. Preload increases the amount of force it takes for the spring to start moving, whereas vvc effectively changes the springrate, meaning the force graph will be steeper. If you know linear equations, it's essentially the difference between the y intercept (preload) and the gradient (springrate). Vvc changes the springrate, not preload.

@RyanAlexanderBloom

Normal atmospheric air is 78% nitrogen and 20% oxygen. And the molecules of N2 are only 2.6% bigger than O2. So there’s not that much difference using N2 over air as only 1/5th of the air in air isn’t N2 and that 1/5th is only marginally different in terms of size and mass.

@benasquith26

I can speak for them, they will say it’s a terrible idea, it can weaken your frame quite a lot. It will also void your warranty, I don’t think your bike being from 2012 will have it though. There are people who have done it but it’s advised not be done but you could try it if you want but doddy has said many times not to drill holes in your frame.

#askgmbntech. I have a 2018 nukeproof mega 290 comp and it has a rockshox super deluxe rear shock. For the last month my shock has been losing air as my ride goes on. I am forced to bring a shock pump with me and pump it up at least twice in a ride. I have replaced all the internal seals and it is still losing air. Do u know what is wrong

I don't understand most of the videos because on a my first bike, ht. 😂 But watch it anyway. Maybe In a few years, if upgrade to expensive front fork or fullsus this would be useful. Good videos though.

This info was truly *shocking*

If anything this has made me more confused 😕

In regards to shocks. Why is it normally recommended to run slightly more sag on a progressive frame than a linear one? Why not the opposite as 30% sag at the shock is far more on the wheel travel. Why don’t set the bikes up with a percentage of wheel travel rather than stroke length? #askgmbn @gmbntech

9:52 ?? confusion in explanation there. May i try, it's not the piston that push oil in the expansion chamber, this displacement is the result from the volume of the rod that enter in the piston sleeve chamber. english not my langage so please appologize. thx

Shock bearing mounts is the most potent snake oil i've seen in a while

this video is shocking! o.o

Yo guys, question here: Yesterday I found out the set screw that keeps the rebound knob on my new fork (RS Pike) went missing. Probably wasn't tightened properly at the factory. Miraculously I didn't lose the rebound knob itself, so I pulled it off to make sure I don't lose it. Will I risk damaging my new fork if I ride without this knob in place? (until I get it fixed ofcourse) The hole where it plugs into is kind of exposed at the bottom.

No issues with assembly for me kzread.infoUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L but I could see where some might benefit from using an experienced bike assembler/mechanic. I'm an older rider starting back after a 10 year break. This bike exceeds my capabilities and has been easy to get comfortable riding. I'm mostly on easy trails with almost no street riding and have not been disappointed with the performance of the bike. My fitness level is far below what I previously rode with and because of that the mileage is going on the bike slowly. While I'm losing weight slowly, the bike seems to tolerate my 220 pounds just fine. The bike has been used by several family members ranging from 5'5" - 5'9".

Most sliding systems use two bushings: one at the top, and one at the bottom. Bushing overlap is the distance between these two bushings. More distance (and overlap) equals a stronger and stiffer system.
