I got airs Benjamin rock shock spent on forks on the specialised mountain bike. 9:44 From England from Worcester. I bought my special fork about 3 weeks ago. Cost me 200 pound. It's the best thing I've ever had. 9:44
wish i had a friend like that to hold my bar lol ;)
Love the look of those new revalations on your bike 👌😎🤘
I've been waiting for this forever 👍👍
Thank you so much gmbn you guys are very helpful to the cycling world stay safe guys
Very useful video and explanation. Thank you mate
Excellent video. Very appreciated. First time I've heard to open up rebound all the way. Now I'll have to give this a try .
Thanks, this was very informative. I upgraded to an air fork and really needed a concise no BS explanation. 👍👍
Just got my new rockshox forks and it's at the bike shop as I'm writing this. Can't wait to try it out and thanks for showing me how to set it up doddy! Fantastic content as always 👍
Cheers Doddy love your tech videos I have learnt so much.
It’s a tricky process to tune your fork, with doddy tips is easier!!! Thanks doddy and your team.
This is what I've been waiting for, thank you so much! 😇
Thank you. The first video that tell us new to air for how to set up our forks. The only video that actually tells us to open the compression before anything adjustments. Some YTer somehow blew pass this.
I have cheaper coil fork and it has rebounded and a lock out and preload I love it it’s a big upgrade from my last fork
Great guide. Suspension was alien to me until now. Doddy makes it sound so easy. 👍
Once you break it down and think about why rather than how...it all becomes easier to understand :)
Thanks for this video, super helpful
Exactly what I needed! Right down to it
Doddy you’re the best 👍
Great video Doddy, good detail and guidance! 🤘
Thanks Dan, glad you found this one useful
Great video doddy 👍
Thanks benji
Great vid very helpful!
Higher end coils are wild too. 2012 Marzo 66 CR here. It tops my 2011 Revelation dual air BY MILES!
#GMBNTech Is Jess not the coolest lady ever? Might have an MTB crush but love her enthusiasm and happiness every show. You very much inspire me to ride more!
GCN?!!
Fixed it! I’m back and forth between the two channels all the time.
Dont tell #gmbntech but I sometimes watch GCN too! :)
We're watching you guys! Keep it here 😉😂
Love it!
Thanks a lot!!!! Great job!!! 👏👏👏👏👏👏👍👍👍👍 Very helpful!
Great video!
Thanks, glad you enjoyed it
For us total newbs, it's not clear which direction is "fully closed" on the rebound adjuster.
5:29 "However is much easier if you have a friend. Hey! Friend! *Jess appears* I have a friend now 👍"
I honestly did not expect that Jess would appear right next to you, Doddy XD
Could you make a video like this for setting up coil-shocks? I got a Scott Gambler as my first downhill bike, but i can't really figure out how to set it up properly. The bike manual says 40% sag and fox says 20% to 15%. But those numbers seem a bit extreme. Now I set it up where I sort of like it, but it is not ideal.
I can't get the find a friend trick to work help plz. Is there a park tool I can buy for this?
Just use the tree Dinny!
Nice vid doddy
Cheers!
@@gmbntech no problem you deserve it
Ah....gotcha, I should unwind my rebound screw before setup sag! Thanks!
Nice ❤️
❤️
Could you possibly do the same for Lefty tines?
This is great and I have a question. What affect does head tube angle have on air pressure in the fork? Given a slacker angle has the front wheel more out in front and I would think taking more of the impact.
Nothing that isn't taken into account when you set the sag James :) The fork will act in the same way throughout countless compressions unless you change the angle!
What effect if any does a rear shock (i.e. dualie) have on fork setup?
I’ve got rockshox recon rl silver, they don’t have the red band or the percentage printed on the fork how would I go about setting the sag on them?
So probably a newb question butI have 120mm travel Rockshox gold fork. Looking at the o-ring movement I only have 6cm. The PSI is correct for my weight etc so...am I missing something?
I have just got a vitus nucleus with an sr suntour fork but the rebound damper at the bottom doesn’t stop turning no matter what way you turn it.. is it supposed to be like that or is it broken?? Bike is only a few days old and have rode it 4 times
Can you do a video on finding creaking? I have a creak and I cant get rid of it
D.C Hazen - Once creak I had was sand or limestone particles that got inside the seat post tube. I had the bottom crank replaced thinking it was that, but it didn't go away. After I removed the seat post, I found the particles in there and washed them out. No creak after that. Took a few years to figure that out. Hope that helps.
Dear GMBN Tech, what happens if you just put the desired air pressure and first you dont touch the rebound "button" at all ? Thanks in advance.
hi guys, when is the suspension 101 video coming, mentioned in this video? #askgmbntech
So how far into it is "6 clicks" like 25% in your case?
Is the scott voltage fr20 with a double crown fork a good frerride bike?
Yes but if i were you I would ge an intense m16 there on sale now 50% of there normal price
Is it ok to ride at about 10% sag. I like to have my suspension hard for jumps gals and drops. Is it worth easing my suspension and use 30% sag then I don't want to use all my travel on small jumps then bottom out on larger ones?!?!?!
10% isn't really enough for sag. Remember your fork has to extend into bumps as well as absorb them! Use 30% sag, but consider running more compression or a volume spacer to absorb those small bumps better without blowing through your travel. And actually, you do want to bottom on those big features, in order to actually use all of your suspension travel!
hey doddy,
I am currently running a Manitou Mattoc Comp Pro 2 Fork with 160mm travel and have set it up with about 55psi (im about 73kg with everything on) and while the SAG looks correct, the fork far to bouncy if I paddle while out of the saddle - even if I put LSC and HSC at max.
Would volume spacers help? Any advice?
Cheers!
Yes definitely if your fork takes volume spacers you should play around with them
Hope this helps
I think the comp has an open bath damper so you can put a higher viscosity oil in it to slow down the movement. Low speed compression should control rider input like pedalling out of the saddle. High speed controls how fast it compresses when you hit something or drop off something. When I put H/L compression on full on the Mattock it feels terrible and doesn't move much at all. My Mattoc pro came with spacers that I used to make the fork more progressive. It doesn't really stop the bounciness of the fork.
What's the name of that Rockshox App called? Link perharps?
trailhead.rockshox.com
Concerning Rebound: is turtle open or closed?...and what is rabbit?
I don't get it. First fully unwind fork (on rebound button) or fully closed is when rebound button is turned all the way to the "deer" sign, then later fully closed rebound is when the rebound button is all the way to the "turtle" sing turned. Is this some kind of mistake or did I got something wrong here?
I noticed on his bike his front brake is his right hand. Is this a common thing?
I would take a Marzocchi Bomber z1 any day . Coil sprung forks were so awesome .
Problem!!
Im using the fox float x2 with the right Sag settings, all Tokens and 1 click highspeed compression from closed. But its often bottoming out on big Jumps or Drops. I just added so much air (230psi/65kg)that the Shock is nearly bottoming out 1-2 mm but now it dont feels nice on small bumps. What can i do?
Dirt Rider let it bottom out unless it makes a big huge noise
@@mikethomas4445 😂I expected a different answer
I’ve got a giant anthem 1 2027, and I feel like if I set the 20% sag the fork is TOO soft, I weight like 73 kg and for that sag I set like 60 psi. If I set that sag, I’ll bottom the fork with very small bumps. What shall I do?
Try more pressure. 60 is pretty low. Are you sure it's really only 20% sag?
I have a fox36 fork and there are no recommended settings for a rider of over 113kg. Im 129kg rider and still struggling with settings
What if my ford stanchions doesnt have any percentage indicators? How will i know the sag percentage?
With a calculator and a ruler
When you mean unwind the rebound do you mean make it as fast as possible or as slow as possible?
As fast as possible
Also interested. Replying so I get notification too lol
Thanks!
So closed is slowest, wide open is fastest?
Yeah that’s right
I have rock shox reckon silver Rl. It doesn't come with a sag bearing , so how can I tell how much sag I need . Thanks guys!
You can temporarily put a zip tie (cable tie) or twist tie around the stanchion if your fork doesn't have the o-ring as a sag indicator.
If you mean the stanchion doesn't have the markings for sag percentages, then you just need to know your fork's maximum travel, measure your sag, and divide the sag by the maximum travel. If you don't know the travel, you can let all the air out and push it to full compression to find where it bottoms out, then reinflate it, and measure the amount of stanchion that was hidden at full compression.
@@mattgies thanks . Helped explain a lot bette9r
How often
What is that at 3:47
So the heavier i am i need to get closer with turtle hahahah 😂 Im 87kg and setup says i need 112psi but i like my forks firmer at 120psi... At least i gussed the -2 rebound... Feelings dont cheat on me sometimes ..
Used the recommended settings for my pike but it was like a jackhammer on the roots, I still put up with it for a couple of months before popping in another token,dropping the psi and messing with the rebound, it's still not perfect but much better and I'm too lazy to fix it or make it worse again.
Most of the time, those recommended setting are somewhat close, but setting by sag will yield better results. Start with recommended and tune the pressure up or down for sag according to your preference. If it's bottoming out but you like the feel in general, add tokens. I run way lower pressures on my Rockshox Pike and Reba than what the tables suggest.
To get my sag to 25% it is way way less psi than it says on the fork. Confused!
What i need is an airfork xD
That watch lol
I got Magura menja. I got 1 cm sag on Proper psi. Why
Wan Huar adjust psi
It went together easily in less than an hour. czcams.com/users/postUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L Make sure the front fork is forward or the pedals will hit the front tire. Tires are both a little soft so it needs air before I ride it. The rear wheel didn't come with a clamp regular bolts hold it on. The front had the clamp. No scratches out of box. Rims are a little off with a slight wobble. They could have spent more time with the spoke tool fixing the run out. So far out of the box I'm happy with it. I did replace the pedals with a nice aftermarket set. After riding it a bit my A$$ is a bit sore so I ordered another seat. Overall I'm nearly 60 and didn't ride a bike in 30 years. I like my new 29" Schwinn. It will be used for casual rides with my friend.
*sometimes I superglue my thumbs to my nipples and pretending I am T-rex*
Can this hold up to a 279 pound Kid?
what is that front tire?
Looks like the Mountain King.
sp00n yeah, indeed. it's the 2018 mountain king. thanks
If you are a basic twat like me, and your forks feel like they're locked and wont compress at all, take the air cap off and let some air out, but dont go mad on letting it out. I have been searching for hours how to fix it and that done it for me - Will need to add some more air but better than riding a hardtail with no front sus at at all. I'm not assed about getting it set up perfectly i just wanted to be able to go over a speed bump without having to stand up lol. hmu in 4 years time when you see this, yes you.
i try the snaping finger trick again and again,but Jess wont come! Jess where are you?!?!
Who's Doddy's friend eh?
Did she bounce up and down on it for you in the end?
What if my fork only has compression dial? No rebound dial :(
Wish I could make a beautiful lady appear.
go to a hooker
so i cant set up my shock because i dont have friends
ow dude, ... where can I get a friend like that, snapping my finger and she is ready in front of me ....
