Nice one Doddy. Good to see all this broken down in one place. This vid will be very useful for a lot of people Im sure. Glad to see some animations of what youre explaining too, always helps.
“Dramatic Reconstruction” lol. Thanks for this video. Suspension is a bit like a dark art to me. As much as I try and get my head around it, it never seems to happen.
Nooooo. Compression is a noun. The verb is compress. This is kinda glaring when you put that as headers. Rebound has both noun and verb forms but in this case it is a noun.
Nice vid doddie...however when u show compressing to charge the neg chamber(6:42), u have the shock pump still fully attached! Tusk! U can see the air being forced back into to pump, moving the needle and not (effectively) charging the neg chamber therefore. Plus can damage pump (accuracy). Always disconnect pump before compressing...just enough to close the valve/release pressure in pump is ok, don't have to fully undo/remove if pressure in pump released...
Also peops, rockshox u pressurise shock (not forks, this is shocks only) to 100psi then compress 5 times to charge neg...not to body weight as per text...👍
I personally prefer to have slower low speed rebound for stability (less bouncing off of small bumps and things) and increased low speed damping to prevent excessive fork travel in the first place so it doesn't pack down. I find this helps keep my arms fresh and my line controlled in extremely rough terrain. I just tweak the high speed compression damping to just enough to avoid violent bottom outs but otherwise leave it as open as possible.
I’m thinking about buying an Orange 5 but new shocks seem to be metric. Do you think there will be issues buying into what could be a rapidly redundant imperial standard?
Speaking of suspension, I've been have an issue with my fork set up and was wondering if you guys had any advice. I've been noticing fatigue in my arms on really rough trails (flying monkey, UT to be specific). So far I've tried lowering compression and have tried both faster and slower rebound. With this set up i had a violent bottom out on a drop with 2 blue volume spacers, so I tried increasing pressure a little. Any red flags or suggestions? Maybe arm strengthening? The fork I'm running is a 2017 160mm fox factory fork
Great video. I have an opportunity to replace my 2015 Fox Factory Fit 32 120mm for a 2017 Fox Step Cast 32 100mm at a deeply discounted price. I am 5’9” 200lbs and ride a Santa Cruz Tallboy 29er that was originally spec’ed with the 120mm. What are the negatives to making the switch? Are there any?
I really like your videos. I just bought my first mountain bike a used 2013 Santa Cruz Tallboy C. I live in Jamaica where there isn't lot of trail riding per se but it's very possible given the make up of the country. The Bike has dual shock absorbers both with 100mm of travel which from watching your videos I think will be fine for what I'll be doing. I however want to know if it is possible to safely change out the shock absorbers to 110mm rear and 120-130mm front or can I get the existing 100mm absorbers to perform like 120mm absorbers by adding those things which I totally forgot the name?
Hey I am watching this vid in 2021 so if you still have not changed your shock and fork I'll tell you uf you can. So you can change both the shock and the fork either up 20mm max or down 20mm max. for example: Now you have a 100mm fork you can get a fork up to 120mm or else the geometry if the bike will change quite a bit. Same goes on for the fork. Please tell me If I helped you!
#Video Idea Go through differnet full suspension pivots systems, single pivot vs vpp, compare brand designs of suspension designs and which is superior?!. I have a commencal tr 2018 and I feel like its Bob's when i pedal, what would you recommend for setup?
#GMBNTech Where does VPP suspension fit in the hierarchy of suspension designs? Riding a SC 5010 and wondering if I need more suspension..... My focus is on climbing, 190lbs on a Fox Float Performance 34. thank you Doddy!
#askgmbntech Hey I Doddy, great show. I finally have a full sus and just got a Trance 27.5 4 anfd it has a Giant branded rear shock with only one dial which I understand to be rebound. Are these any good at all and any setup tips?
How does Propedal work on a Fox Shock? I have fox a float rp23 and there is a noticeable difference when it is on but, I don't know how it works. #askgmbntech
Old question, but in case anyone else wants to know, the reason for high speed compression vs volume spacers is to increase the damping (absorbing energy), where volume spacers increase the spring rate deeper in the travel instead. If you have a shock without enough high speed compression damping, but with lots of spacers, it'll move very easily in the initial part of the travel and then get a lot stiffer later on. with repeated hits, it'll pack down against the stiff part at the end of the travel, but because the spring is so progressive, it won't bottom out as hard. Really, the end result is almost like having a shorter and harder fork/shock after the first couple hits.
#askgmbntech Great video thanks. I still don't get how the rear shocks are measured; for example: I run a 120mm forks at the front, that is actually 120mm... I can measure that on some rides to determine the % I am using , so I can adjust...but on the rear, I also have a "120mm" travel ... but when you measure it, obviously that is not 120mm... Could you please enlighten me on that? thanks.
I have a 140mil Rock Shox Sektor fork. On my fork there is only one Compression adjustment knob. How do i know if i have High speed OR low speed compression adjustment on My fork?
Doddy，I am thinking abt the idea that u have to test the Chinese carbon frame. Will u visit China to test them out ? If u r, which city will u visit? Looking forward to seeing you in China big fan here~~~
I think I might have to watch this one a few times...a lot of information ....Thanks
Nice one Doddy. Good to see all this broken down in one place. This vid will be very useful for a lot of people Im sure. Glad to see some animations of what youre explaining too, always helps.
Excellent suspension descriptions. I heard several concepts I have not heard (or understood) before. Thank you.
I love my 2019 DVO Sapphire 34's coil sprung negative spring....... Best fork I've ever owned.
Doddy is so good at explaining things he could do a video on hair products and I wouldn't be bored with it.
Doddy...Happy New Year! Thanks for breaking the tech down Barney style...very helpful.
It's about bloody time that someone broke this down Barney-style. Thanks Doddy and GMBN! Now it's time for me to get my fork dialed in...
Nice animations. Dramatic reconstruction, lmao, great fun! Really well done video gmbn.
“Dramatic Reconstruction” lol.
Thanks for this video. Suspension is a bit like a dark art to me. As much as I try and get my head around it, it never seems to happen.
Thanks for the awesome video! It really gave me a better understanding of the suspension on my bike.
Very informative might have to watch it a few times - alot to sink in.
Great video!
(who else typed this after just seeing the thumbnail?) well, it's from GMBN, so.. it's surely going to be great!
The best vid I have seen to explain how all that works. Bad drills at 07:39 though Doddy, riding without a helmet...
Nooooo. Compression is a noun. The verb is compress. This is kinda glaring when you put that as headers.
Rebound has both noun and verb forms but in this case it is a noun.
Great information as always Doddy, cheers!
I NEVER knew what trunnion mount meant, thank you doddy
I bought a really good full suspension bike with fox 34 fork and a fox dps rear, and this video has saved my life. Everything is a mess for me
You lucky bastard!
Thanks @gmbntech! @doddystar for the great content! Love this info!

"Pedalbob" = when Bob is your uncle and he is too damn slow going up hills. Anti squat - married to bob your uncle

😂👌🏻
Good video ! Much needed
the man is a cycling encyclopedia ! he should go on mastermind !
Great video Doddy what Santa 🎅 bring you this Christmas 🎄
I've seen and heard that coil springs are coming back very strongly, even for forks.. Why?
I personally prefer to have slower low speed rebound for stability (less bouncing off of small bumps and things) and increased low speed damping to prevent excessive fork travel in the first place so it doesn't pack down. I find this helps keep my arms fresh and my line controlled in extremely rough terrain.

Brad Williams it’s a fox fork so the travel can easily be adjusted up to 120mm if you wanted
Awesome video! Even though I know most of these things I still enjoy watching these
Do a vid on how to service a coil shock
Great video!

Best bike for someone looking to get back in to MTB'ing?. Ideally looking at full sus and 27.5"
Hey
I love this channel so informative

Too much anti-squat can also result in pedal bob as the shock is being pulled in extension by every pedal stroke.
Why hasn't pre load on coil forks been described because alot of us have it as its cheaper but I'm still not sure what it does
Doddy rides a Nukeproof? He's never mentioned that before!
#askgmbntech how do I tell whether or not my bike can fit an internally routed dropper. It's for a polygon Xtrada 8
Awesome. Thanks.
How does Propedal work on a Fox Shock? I have fox a float rp23 and there is a noticeable difference when it is on but, I don't know how it works. #askgmbntech
Compression isn't a verb... It's a noun.
great stuff thanks

platform? Suspended/non-suspended weight?
This is awesome!
the diff between SR Suntour XCR vs. ROCK SHOX forks
Great video Doddy this will help as I'm having this problem with my duel sus* thanks 👍
#askgmbntech I am gonna buy a new hardtail xc bike should I keep my old bike for commuting
but it's really crappy and I m gonna have much costs on it.
Is a 450 pound spring on a rockshox vivid softer than a 350 pound spring?
Daniel Augutsson the 350 pound spring is softer
#askgmbntech Great video thanks. I still don't get how the rear shocks are measured; for example: I run a 120mm forks at the front, that is actually 120mm...

I have a 140mil Rock Shox Sektor fork. On my fork there is only one Compression adjustment knob.
How do i know if i have High speed OR low speed compression adjustment on My fork?
It's blue and it will be low speed compression.
As Der Man said, if you have one, then it's low speed compression.
Doddy，I am thinking abt the idea that u have to test the Chinese carbon frame. Will u visit China to test them out ? If u r, which city will u visit? Looking forward to seeing you in China big fan here~~~
Please do have a look at this if your sponsors will let you.
It hurts, please stop, OMG just like Blake says “Just go faster “
need some more info on coil shocks, most videos just focus on air #askgmbntech
1. Some Enduro frames dont Work with coils because of little progression.
2. More supple but less poppy than air shocks.
3. Need less maintainance
DT Swiss, DVO, Manitou and possibly others still use negative coil springs, theres nothing wrong with them, they work just fine.
Esp riding in the cold!
#askgmbntech Hey Doddy, can you explain what is fork topout and how to get rid of it? Thanks
2:00 - that looks weird...
what happend to "TALAS" and will we see it again??
It didn't seem to be popular enough to continue... We suspect the improved geometry of our times has helped eliminate the need for it.
v interesting vid
Compression is noun
In which case, compression is A noun... if you're going to pick, do it in a grammatically correct way.
Hello doddie
Doddy
Tomi Saaranen thanks
No problem 👍🏻
It would be very helpful if you could show irl extremes of each thing.
Great amount of info just got a full sus so this info will come in handy
Love your channel
Good vid
NOUN!!!!
Legend has it if you are early Doddy will reply to you
What??
Clearly not, in this case😋
Lol agreed
@@mitchymacaw5916 Legends can be interpreted in many different ways.
Hi GmBm
Explain "metric". Pretty please.
"IFP"? Not explained.
12:38 Didn't know this term, but it was *RIGHT THERE* on the screen as he mentiones it - no biggie!
First
Third 😂
