As usual, the best treatment of this subject on youtube. One thing I hoped Doddy would do is, for pedagogical purposes, explicitly call it "rebound damping" and "compression damping" rather than the shorthand "rebound" and "compression" since, to a complete beginner, a statement like "to reduce the pogo stick effect, add more rebound" sounds like the opposite of what you want to do-since an actual pogo stick already has LOTS of rebound. For teaching purposes "to reduce the pogo stick effect add more rebound damping" makes more sense and may be less confusing to a novice, though I understand the shorthand phrasing is completely understood by experienced suspension users.

Yes he means rebound damping, not rebound. Plus or a snail logo is more damping. It's the only part of the video I would change.

"Just like on suspension forks, rebound is always red and compression always is blue" *laughs in Manitou

Great instructional video! NJ USA newbie here. This really helped me understand the functionality of the front and rear suspension. This also helps me decide if I should upgrade my suspension or make some minor changes/adjustments to them. Thanks for posting! & Keep Riding.

I agree with the below comments-you are a great teacher and the amount of detail is perfect. I am new to this sport and want to learn as much as possible. Thank you

this was crazy helpful! Doddy is a natural communicator and teacher.

I love this guy what a great lecturer. I literally listened things that I already know, he explains things like a story.

The focus and pic quality is great and Doddy, as always, is simply the best.

Brilliant explanations! Thanks! So confusing with so many options on the forks and shocks.

Absolutely superb presentation once again, Doddy.

Great video again. Educational as always, I've learned a lot. Very helpful, thanks Dodd!

This video is so amazing. Thank you so much Doddy. ❤️

USD forks were introduced to motocross in the early 90's, with the road bikes not far behind. Conventional forks are still used on many models other than sports bikes. So USD forks on motorbikes are still called USD and conventional are still conventional. Exactly the same as on mountainbikes.

Was just going to say this. Conventional was how it all started and should be "conventioonal"

Also the longer the travel of the fork the more it needs to hang below the axle in a conventional fork. Just have a look at the last of the conventional MX forks. They were having ground clearance issues. MTB doesn't have anywhere near as much travel so it can all be packaged above the axle.

Perfectly explained! Thanks Doddy!

Great work Doddy and the GMBN team! This video is very informative! 😀 Hopefully in the next video Doddy would touch on the DVO suspensions since that will be the one that I am having for my bike. Would really appreciate that! Ride safe always guys and God bless! 😀

Excellent information as usual, Doddy. Thanks!

Well explained and put together, thanks mate

Great vid. I learned some good stuff.

Thanks Doddy!

Nice vid doddy just got a scott genious and getting to know my suspension

Nice video , I really like how you explain

I have no idea what this man said after I watched it three times

At one time I owned a Lefty fork. This was on my Cannondale Jekyll. It got a lot of looks. Besides that it was also great for riding in wet conditions because you wouldn’t get it caked up like on a standard fork.

Doddy da man

What a brilliant video

Very good video.....!

Really helpful thanks

Bought a Scott aspect 740 XL with suntour XCM front fork and I am happy with it so far. Just bought for $150 :) :) I will save up for a gt fury

Thanks

Legend.

Tidy content, crispy audio and tasty DoF!

Suspensions are my favourite subject

Thanks !! Mate !!

reat video and very informative., I've learned a lot

The classic Vespa still uses that trailing style front suspension :).

thanks sir

First suspension fork was a triple clamp sr suntour which came on my Saracen Raw DH circa 1998, they were absolutely poo. I upgraded them to a set of RST 461DH with a massive 100mm travel, the off white with red lettering looked mint on the black and red bike. I then upgraded the rear shock from a no brand piece of crap to a rock shock deluxe I got off a friends brothers old voodoo frame. Thing was a tank but a plusher tank after those tweaks. That was the glory days of the sport, the World Cup XC and Dual came to Newnham Park in Plymouth, as a 12 year old lad going to a place within riding distance of my house and watching Steve Peat , Brain Lopes, Wade Boots etc race made a serious impression. The money in the sport back then was crazy!

Any chance of an "all you need to know about retro suspension" such as Mag 21s, Marzocchi Bombers etc from the 90s?

Yeah man I had some circa 2000 Z3 Flylight 100’s on my jump bike as I couldn’t stretch to a Z1 drop off. I remember the launch of the Boxxer and the SID, what an exciting time it was...

Hey Doddy Great informative video as always. I have a question about rear shock reservoir location. Last year I went to a bike show here in Toronto and one of the things I noticed on most of the long rear travel bikes was the rear shock reservoir was located at the rear of the bike more so attached to the left chain stay,but I have yet to see this again any reason why. Thanks

New drinking game, take a shot every time Doddy says "ok" in this video xD

I would like to know how my shock has 130mm of travel but the actual shaft looks less then 100mm

@James-dn1hu

3 жыл бұрын

If your talking about rear suspension it’s based on the travel that the axle moves in and with the added leverage and depending on design the axle will move 130mm rather than the actual shock shaft being this size.

Great Video Doddy like always but this was especially action packed. Would love to see graphics of the insides of both with you explaining the airflow. I get that air is the main driver but when you talk about oil it confuses me a little ie is that just for aiding the slide? Is it air and oil that goes into the piggy back? In the coffee analogy is it the filter holes that are changing and not the liquid? I’ve a new Fox 36 but didn’t have low and high speed compression. How does that work?

Great vid Doddy! As always! 🤙🏽

Great video Doddy. How about Wren fork from Wrensports. Inverted fork from 100mm to 150 mm. Would be nice to see a review from u about them.

Dude, this was sooooooo goooood🤘

You're on top form here Doddy, brilliant analogies

Hmmm yhea. I'd be amazed if they shipped Forks by air mate so... 🤔 If flying your bike make sure you take most of the air out of your suspension.. Maybe you could stash whatever you might need in there instead... 🤔 😉

Liked the old Amp/concept linkage forks so much that I have 5 of them lol.

Can you please do a complete coil shock service video - one with a piggyback) 🤘🏻

Quality vid AD. Clear, thorough.

Magnífica explicación. Doddy must be the nicest guy in the world. Thanks for all the knowledge you share. Greetings from Peru.

why does everyone say fast and slow rebound and compression but the adjustment is + or - ??? Do I put more (plus) to slow or speed up the respond or compression ????

Greetings Doddy Could you please cover the new tech from Avalanche Suspension.

being new to e.biking my recent purchase of a engwe m20 has left me somewhat puzzled. if i replace my rear shock with a shorter one it will lower my seat [which is great for me] my problem is will it alter the geometry of the bike and make it dangerous or will it be ok? TIA stan the newbie. ps a great video keep em coming !!!!!

Seeing all the complexities of shock absorbers, I think I'll keep my Montague folding hardtail 26" mountain bike.

Sag is the amount of initial preload on the spring, whether it is air or coil.

If my downhill bike has a coil spring rear shock, can I swap it for an air shock?

Is it possible to remove the rear spring shocker permanatly? I don't want the rear shocker on the bike anymore, so is it possible to remove it permanatly?

I have a Rockshox compression knob that feels looser than it did when new, but still functions as it should. What causes this? And how can I fix it?

#askGMBNtech I have had a hard time finding good discussion on when, for whom, and why the mid range forks are good enough. Or perhaps more important what terrains are mid range forks always going to be adequate, when/what will be speeds that just reach the limits of those forks. Another point in that discussion I'd like to see is for bigger riders, bigger weights. Currently, I know low end forks are adequate for many folk because they really don't ride at all. Mid range forks tend to get called trash by most riders' comments and reviews with very little reasoning in the dismissal.

I'm as confused as you are in this regard. It'd be nice to hear Doddy's thoughts on it. I have been riding a 10 year old, second-hand Rockshox coil fork for years. I have no complaints. I recently built a bike with a Suntour Durolux 36 and have been really enjoying it. Both of these forks are considered mid-tier, but I've had a blast riding them. Is this because I don't know how nice the mega-expensive ones are? Is it because I don't ride hard or fast enough to need the snazziest fork? I am ~200 lbs, maybe a touch more with all of my riding gear, and these forks have held up well under me.

What’s does pre load down the forks

One of the goodones! great video!

A couple of things here. Moto-forks started out just like our conventional forks of today. The "upside down/inverted" fork came much later than the conventional fork. Doddy, you're probably too young to have known that. :) And for Gods sake people. Your mountain bike has a FORK on the front (singular), it's not called FORKs (plural), there is just one fork on your bike. Sorry, just a pet-peeve of mine.

solid presentation. you are a great teacher.

The other advantage of running USD forks is less unsprung weight,, which is why high performance road and dirt motorbikes tend to run them. The big negative of USDs, however, is having the fork inners far more exposed to damage from rocks, etc.

I just my set my settings to midway and just go out and enjoy my riding instead of messing my head up with a myriad of different tuning ways. Mountain biking doesn't need to be complicated.

The top MotoGp Forks are hardly "over built" for strength. They're as light as they can possibly be, the expense isn't important in any way which is what actually gets the hit, the price of making them. Yes they're to big and heavy for a MtB, yes they can be heavier as the engine takes the strain not you but over built? Nope. Great video though as usual.

#askgmbntech Hi Doddy. I absolutely love the show! And I need your advice: I'm planning to replace the RS Monarch Plus Air Shock on my 2017 Specialized Enduro 650b with a Cane Creek DB Coil with a progressive spring (450lbs; BikeYoke low-geo yoke to mount). With gear I'm 63kg/ 139lbs. Leverage ratio of my Enduro is 2.98 with a rather linear curve from what I could find out. I don't need the adjustability of an air spring and I feel with my current setup the rear wheel grip isn't great. Do you think a progressive coil is the way to go to gain more grip? And would a coil shock make me feel the trails more or would it rather deaden the feedback? Cheers!

#askGMBNtech #GMBN My XC mtb has a 15 x 100 fork with a 51mm offset. If I upgrade my fork to a 15 x 110 with 51mm offset will I need to change out my front hub too? Or is there a way to adapt a 15x110 to a bike that originally has a 15x100? Thanks and keep up the great work!
