VALENCIA, CA - A cold front was fast approaching the Pacific Northwest, and with a week of freezing temperatures in the forecast the timing couldn't have been better to take a trip down to California for a visit with DVO Suspension. The purpose of the trip was to put some miles on the company's highly anticipated Emerald fork and Jade rear shock, as well as to see where their innovative suspension designs are born. The company's headquarters are located in a small industrial park thirty miles north of Los Angeles, and while the actual manufacturing takes place in Taiwan, the bulk of the design work and testing takes place in this modest two story warehouse space.
A large, open workshop takes up the majority of the downstairs, with all the tools necessary to assemble and disassemble a fork or shock, and the latest models of various downhill bikes fill the workshop's corners, test sleds for DVO's new products. There's a suspension dyno connected to a laptop computer tucked up against one wall, a tool DVO uses to push their suspension products to the limit, monitoring factors like rebound, compression, and operating temperature. While the first floor is dominated by the workshop, the heart of the operation is upstairs, in a small office space that houses the workstations where ideas are converted into 3D computer drawings. A floor-to-ceiling whiteboard covers one entire wall, filled with hand drawn charts and drawings, a giant sketch pad of ideas, some that will never see the light of day, and others that are nearing production.
Most of the DVO crew previously worked at Marzocchi, and the years of shared experiences makes for a comfortable work environment, with plenty of good natured heckling filling the days. Spend 40 hours a week with someone for more than a decade and you'll know exactly how to push their buttons, and these guys don't hold back. It's all in good fun though, and there's a palpable sense of camaraderie; everyone is working hard towards a common goal - to produce the best suspension products possible. The pervading attitude is reminiscent of a time when men tinkered in garages trying to build rockets to take them to the moon, and while DVO's goals may not be quite as lofty, they're still aiming high. The difference is that with over 80 years of combined suspension experience amongst them, their goals seem much more attainable than building a homemade spacecraft.
Once our tour of the DVO headquarters was complete, it was time to get the Pinkbike test rig outfitted with an Emerald fork and Jade shock before hitting the trails. DVO's suspension technician, Ronnie Dilan, and Tom Rogers, the developer of the Jade, got to work installing and setting up the anodized green components on our GT Fury.
Suspension Setup
DVO Emerald Details
• Intended use: DH racing
• Travel: 200mm
• Air spring
• Carbon Torsion Arch (CTA)
• OTT Adjuster - allows the negative spring to be externally tuned, improving initial sensitivity
• Damping: twin tube open bath, adjustable high and low speed compression, dynamic rebound adjust
• Upper legs: 7000 series alloy, 42mm externally tapered
• Stanchions: 36mm hard anodized PTFE coated
• Weight without CTA: 2950 grams, CTA: 300 grams
• MSRP: $2200 USD
The Emerald's features are similar to what you would expect to find on a fork of this caliber – independently adjustable high and low speed compression damping, adjustable rebound, adjustable air pressure, and a unique feature that DVO calls Off The Top (OTT). OTT adjusts the amount of preload on the fork's coil negative spring, which changes the initial feel of the fork. Want your fork to be as plush as a down comforter, but then be firm enough later on in the stroke to handle the biggest hits? OTT makes this possible, giving riders a simple but effective way to adjust the fork's small bump sensitivity without affecting the rest of the shock's stroke.
We began our test runs with the air pressure set correctly for our body weight, the rebound set to our personal preference, and the compression settings wide open, a good starting point to begin figuring out the optimum set up. After each run we would assess what we were feeling on the trail, and adjust the fork and shock accordingly, whether that meant adding more compression, more sensitivity via the OTT setting, or changing the rebound speed. It might sound tedious, but it's an excellent way to really get a feel for the difference each setting makes on the trail.
DVO Jade Details
• Intended use: DH racing
• Adjustments: high speed compression, low speed compression, rebound,
• Cooling fins on reservoir designed to aid with heat dissipation
• Internal bladder instead of IFP
• Loader style compression circuit
• Sizes: 10.5 x 3.5, 9.5 x 3, 8.75 x 2.75, 8.5 x 2.5, 7.875 x 2.25
• Weight: 425g (damper only)
• MSRP: TBD
Instead of using an Internal Floating Piston (IFP), DVO chose to use a bladder in the coil-sprung Jade rear shock, a design intended to reduce any potential initial stiction, which helps improve small bump sensitivity. The bladder is filled with
between 160-200 pounds of air via a Shrader valve located on one end of the reservoir. High and low speed compression along with rebound damping are all externally adjustable, and further tuning is possible by altering the shim stack located inside the reservoir.
Besides the external dials, the Emerald and the Jade's reliance on shim stacks is a music to a suspension tuner's ears The use of shims to control oil flow and affect damping isn't new, but the ease with which riders can access and change the shim stack on the Emerald without any oil loss makes custom tuning much less daunting. We spent time in the DVO workshop creating a few custom shim stacks that we'll be experimenting with for our long term test of the Emerald. The configuration that is currently shipping in the Emerald is the same setup that Cedric Gracia ran at the Fort William World Cup, so it's not as if riders will need to go diving into their fork right away to get top-tier performance, but it's nice to know that it's an option, and DVO is more than willing to work with riders to help them achieve the feeling they want from their suspension.
First Ride:
DVO Emerald & Jade
Our test sessions took place on trails in the Simi Valley, which has the dubious distinction of once being the home of Charles Manson, as well as bordering the San Fernando Valley, the so-called 'Porn Capitol of the World' due to the number of adult films produced there, providing employment for the fallen Hollywood starlets who didn't quite have what it takes for mainstream success. It might not be on the top of most mountain bikers' list of vacation destinations, but it does contain several trails that turned out to be excellent suspension testing grounds.
The trail where most most of our test runs took place used to be a road for stagecoaches in the late 1800s, but as time passed the dirt surface washed away, leaving an incredibly rocky path with multiple holes and drop offs just waiting to grab a front wheel and fling an unsuspecting rider over the bars. Imagine riding down a giant rumpled bedsheet made of rock, or a set of petrified moto whoops and you'll start to get the picture. It's also short enough to do multiple laps, which made it easy to try different fork and shock settings to figure out what worked best.
Each lap we took consisted mainly of trying to keep Bryson Martin Jr. in our sights while dealing with the constant onslaught of awkward rock bumps and lumps that filled the trail. Matching Bryson Jr.'s pace wasn't easy, but the Emerald and Jade certainly weren't holding us back, and they gobbled up everything that was tossed their way. Even on a trail that's about as tooth rattling and bone jarring as it gets, we were able to maintain our speed, and end up safely at the bottom without any arm pump or hand fatigue. The Emerald deals with successive impacts extremely well, and it never felt like it was packing up, even on sections of trail with multiple hard hits in a row. The small bump sensitivity of the Emerald is incredible, and is especially helpful on loose, off camber sections of trail, with the fork providing enough traction to avoid skidding out on the marbley surface. The Off The Top negative spring preload deserves partial credit for this sensitivity - it's a feature that makes a significant difference, and one that we can see using often to match the fork to the terrain. For instance, on a smoother, jump filled trail, something like Whistler's A-Line, backing off the OTT would make the initial portion of the fork's travel feel firmer, perfect for getting the most pop off the lip of a jump. On the other hand, for rougher trails, particularly those with extended sections of braking bumps, it would make sense to dial in the OTT to help take the edge off the repeated impacts.
We didn't notice any undue flexing from the fork, even when pushing it hard into sharp corners or through lumpy rock gardens. We'll need more time on it, and a wider variety of terrain, to come to a more definitive conclusion, but the fork didn't exhibit any performance traits that would prevent us from diving right into the gnarliest terrain without a second thought.
The Jade rear shock was trouble free as well, offering a supple, controlled stroke without any fading. Again, we'll want to take it on some longer runs to see how it deals with heat build up, but our first impressions are very positive. One of the test tracks had a decent sized drop with a landing that had seen better days – what was once a dirt transition now had shark fins of rock poking up through it - but the Jade took it in stride, with no harsh bottom out despite the less-than-smooth landing. We did end up altering the shim stack slightly to allow for a quicker rebound speed – the stock setting was a little slower than we prefer, but this is likely related to our lighter than average rider weight. Getting to the shim stack in the Jade is a little more involved than swapping shims on the Emerald, but it's still doable by any home mechanic with a moderate amount of mechanical know-how. No special tools are required to disassemble the shock, which makes diving into it that much less of a hassle.
IssuesOn our second day of testing we noticed oil accumulating on the Emerald's right stanchion. It wasn't a massive amount, but it was enough to warrant further investigation. Plus, pulling the fork apart would give us a chance to see the steps involved in performing an oil change. One of the benefits of the Emerald's inverted design is that it's possible to remove each leg individually – it's not necessary to pull the whole fork off the bike. Once the leg was disassembled the culprit behind the leak became apparent – the lip of the oil seal had gotten folded over during assembly, creating an opening for oil to escape through. We installed a new oil seal, poured in the 320cc of oil that the damper leg requires, and closed everything back up. Performing this service took well under an hour, and only changing the oil could easily be accomplished in less than 30 minutes.
In addition to giving us a chance to perform an oil and seal service, this was also a chance to see how DVO handled errors that occurred during assembly. The calm, collected attitude we'd already noticed remained unchanged – there wasn't any blame or trying to pass the buck, just a quick discussion between Bryson Martin and Ronnie Dilan about updating the Standard Operating Procedure (SOP) at the factory, and that was it. Adding another step to the assembly process will make this much less likely to happen, and it's something that can be quickly accomplished due to DVO's close ties to their facility in Taiwan.
What's Next For DVO?Now that production of the Emerald and Jade is underway, what's the next jewel in the DVO line? According to Bryson Martin, it will be the
Diamond, a single crown, 140-160mm all-mountain / enduro fork that will use technology derived from the Emerald, but with a sealed cartridge system and a non-inverted design. Available for all wheel sizes, the Diamond is intended to go head to head with the top forks currently on the market, and is expected to be available by early summer. After that? An air sprung rear shock is in the works, along with the possibility of an inverted single crown fork further down the line. DVO is working on creating their own carbon fiber production facility in Taiwan, and we wouldn't be surprised to see more carbon make its way into future offerings. Remember the titanium collet clamping system that the prototype Emeralds had? As it turned out, that design ended up working a little too well – the collet provided plenty of clamping force, but the problem was getting it to release its grip on the aluminum tube. Could this design make its way into production, but with carbon tubes instead of aluminum? We'll just have to wait and see.
Pinkbike's Take: | We came away from our visit with DVO thoroughly impressed, and not just with the Emerald and the Jade, but with the overall attitude and vibe that was present during our time in California. It wasn't an act either - we've spent enough hours with shady marketers to be able to see through the smokescreens of hype that can occasionally arise in the bike industry, and there was no trickery taking place at DVO. Their upfront attitude and dedication is what stood out the most, and the lean business model that DVO is working off of allows them to rapidly make revisions and constantly improve their offerings. So, are the Emerald and the Jade one hundred percent perfect? We'll say that we were highly impressed with what we experienced during our time on them, but we wouldn't go so far as to make that claim, and there were a few tiny details that could be improved. Still, the strong performance of both the fork and shock combined with their tuneability and ease of service certainly makes them top contenders in the race for suspension dominance. Keep in mind that our time on the Emerald and Jade shouldn't be considered a comprehensive review, but something closer to a first date. We brought the fork and shock back with us to the Pacific Northwest, and we'll be putting them to the test on the steep, muddy trails in our backyard. Stay tuned for the final results of how this relationship ends up. - Mike Kazimer |

Seriously, Seal Team 6 dosent use this much jargon .
But did it tell you, you can do what ever you want?
im guessing that the test rider is looking at whats coming next when he leaves the berm , i didnt know that PB users needed to know what was happening next as levy left the berm.
also love the fact that your telling levy how to set up his bike even though he probably has more miles on every type of bike out there in the market than anyone in the world with the exception of about 10 people on the planet.
i agree about the seal thing blowing but for you to make comments that the editor is not riding correctly or setting up his bike right is a joke, ive never seen a request for the action shoot to have more action shots even if it means them them "looking somewhere in a berm"
problem also is that maybe your boxxer is good, doesnt mean that there never has been a bad rock shox boxxer to hit the bike shop floor
cant wait for makrippers video series to hit with where to look and how to set your lever like a pro to nail a berm on a flow trail(not dh)
£2200 for a fork and it blows a seal after little use. can me cynical but PB does seem to be doing a good job marketing DVO, hope they are getting well paid
People are fans of DVO because they stated their mission from the beginning, have been totally transparent with the entire process and succeeded in what they set out to accomplish. There's been none of this secret test facility in Italy, Blackbox BS that no one ever gets to ride or know about, yet when it comes to market (5 years later) might work/might not... DVO never said they wanted affordable suspension for the masses, it was implicit from the beginnig that they were going to make the best suspension on the market at whatever cost.
DVO wins. I'll never own their suspension, but they have my respect.
If I slap on a set of these & a jade to my DH bike, I'm not going to go any faster than before.
It's been proven many a time when pros swap around between brands.
Nico, who with BOS developed at the time, a supposed new era of great suspension with the Deville etc. then changed to Fox, and subsequently RS, he's not slowed down. Cedric didn't start winning races again on DVO
Let's assume for a minute hob nob is right and all high end suspension is as fast as each other. There's no question they feel different as anyone who's had a 40 and an air Boxxer and a 888 can tell you. So part of it will always come down to individual preference of these differences. I personally can't go past small bump sensitivity because I like the way it keeps my hands and arms going day after day in the bike park. I had a Boxxer that had too much compression damping for me even when it was full open; would have been nice if I could pull the shims out in the parking lot. My experience with 40's and Boxxers is that they both wear out the stanchions even if you service them regularly whereas 888's don't seem to mind if you service them at all, thanks to the fact they have oil in them. I'd rather ride than change the oil just to save a few hundred grams. It is a real shame the seal was installed incorrectly on this test, but there's little question that more oil on an inverted design should provide much longer service intervals over the long term. And if their online presence is anything to go by, there's little question that these guys are going to bend over backwards to get you sorted if you need it.
I've used pretty much every top end fork out there and judging by my race results, i'm no faster on any one fork or shock than the other. I'm not the fastest guy in the world, but i'm also no squid - i've been known to stand on the top box in my age category in the past...
I think DVO have missed my point regarding BOS, That was considered at the time the 'best' fork on the market, yet you didn't see mid pack racers running them hitting places above their pay grade over the inferior competition... Same with all the riders swapping brands. GM has carried on smashing it when they switched from SRAM to Fox, etc etc.
All these forks & shocks feel different, some feel supple, some don't, we all run them differently, and the gulf between what we run & what the WC riders run is massive. We all see articles about how hard they run their bikes, yet even amongst themselves there are huge variances of setup.
I still maintain you put me on a well setup bike running Fox, RS, BOS, DVO, Suntour etc and time me - i'll tell you how they feel different, but outright speed? Don't kid yourselves.
People will buy these because they are new, expensive, USD & green. The naive mugs will buy them because they believe they will go faster. They won't.
Yet the hype rolls on - for a fork next to no-one has ridden, or likely to, look at the page views and volume of comments.
www.pinkbike.com/video/350904
just because a 16 year old or student can't afford an Emerald doesn't mean the price is wrong
also, before you s**t on Boxxers, don't forget Stevie won on one
Please, suspension wasn't a cool world for us last 20 years. Everything is expensive or shitty. Even both.
So please, to thank us, to make our mtb geek life better, and because you've already show us we could believe in it,
just 2 words... Some blue and gold words:
Ohlins fork.
www.vitalmtb.com/news/news/Spy-Shots-Ohlins-Shock-Available-for-More-Bikes-Fork-Closer-To-Reality,707
Ohlins on Lapierre and Commencal! That looks sick.
I rode a Shiver and ride actually a Dorado, and maybe an Emerald on my next build but only if available in France!
BOS are notoriously difficult to get spare parts for & to get serviced. They've have changed distributors in the UK several times, at times leaving the consumer with no option than to send their suspension back to France.
I wouldn't touch them with a Baguette, never mind a barge pole!
(by the way, Novyparts can take order from all Europe, but I don't know about USA ... Might be pretty expensive in shipping ...)
Each of us has a different feeling on suspensions, and for about 90% of the riders I know, they could ride on a Rockshox Domain DC RC or a BOS Idylle RaRe or the DVO Emerald and not feel a single difference. What I mean is that for probably 99% of your customers, it will be brilliant (like for the RS Pike, thousands of people are happy with the new Pike for instance, while it's just not good enough for me)
In the end, as long as your customers are happy, you're right saying that's the main goal, and I haven't tested one to forge an opinion on how they perform, I just don't bite any longer on over-marketed products (as good as they actually may be !).
So, the next time you're about to say "I'm not into BMX", stop yourself, because actually, you kinda are.

I think it is still overpriced product,basicly everything inside the fork/shock is just miniature copy from mx world,excluding the possibility of removing damping unit without taking whole rearshock apart. Damping units are very similar to Showa "base valve" with floating piston etc...
Really need to go over and say Hi next time I see you guys at Tapia instead of just going "oh hey, the DVO guys are out testing, wonder what's hidden inside the "suntour" forks they've got..." and nervously talking about it with my ride buddies!
That's like back in 2007.
But I guess if you pay more than 2000. - just for a fork, you must believe that this fork is absolutely superior.
And no, the majority of weekend warriors doesn't have a problem with such a weight because they are riding fork around the 3kg mark - 40s up to 2013, Boxxers RC and R2C2, Dorados and 888s.
My fork is a MRD Dorado 2009 with a coil-conversion due to problems with the air-chaimber. It tips the scale at 3,22kg and i'm perfectly OK with that. Because i know the difference between it and a Boxxer WC regarding its work through the trails.
Wow you must be a math genius. Just one question... Do you always believe manufacturer information without verification?
gewichte.mtb-news.de/img/11/b4/50/11b45062d940ade8f58465fee49a96fd645489d2/large_1016306_635050566554502_787079540_n.jpg
The forks you mention cost half as much if you look at effective prices and I guess what denlo wants to say is, that there is no technological progress in a fork that ways significantly more (500g compared to the 2009 Dorado Pro and most of the 2014 forks lineup) and probably performs just as good as an older Dorado, but costs a twice as much.
I really love what the guys at DVO are doing, and there is no hate in what I'm writing... but it's a matter of fact, that there is a lot of hype around DVO just for some shiny pictures and a lot of comments on pinkbike. Some people need more than just that.
Thank good it´s also available in black.
But the best forks are by Marzocchi... Works great even after 3 years without service
@mazze - Dorados, 40s up to 2013 and 888 Ti don't go for half the money of the DVO. A DVO go for 1750-1800 euros, 40s go for around 1300-1400, Dorados go for the same. And i haven't seen till now a photo of the DVO with the weight, thank you for that. But the photo won't change my mind that the DVO is one great fork.
@DVOSuspension - i agree. I prefer to ride a heavier fork that performs flawlessly instead of going super light bit with issues in the performance. That's exactly what i did - chose to buy a coil-converted Dorado instead of a Boxxer WC.
One question on the Emerald though - i have asked you before about that but my question was lef without an answer. Wasn't the Emerald prototype featuring 2 rebound adjustments? If yes, why did you remove one of them in the production model?
I've got a Zokes 66 RCV 2006 which they must've designed.
Phoned Marz (Naz) in N.Van about service and he said just ride the bike, change the oil and keep'r clean.
And that was 2 years ago ... fork still ROCKS.
Rides more enjoyable with reliable designs and performance who wouldn't want that?
Why is the emerald so f**ckin expensive? I think production costs are much lower. All the other forks are expensive as hell, too. I think a lot of people can´t effort so much money for a fork.
All this gives them the edge to ask for the higher price, despite the fork weighting a little bit more than the others.

Way to step it up DVO and be honest about it. Go public and MAN up!
This will pay off for you on the long run!
"Hey John,
I have been waiting for the ermerald to come out since early summer and a friend just told me about the first batch of 300 that will be assembled next September 10th,
Can it be possible to include my name in the waiting list for the first signed batch?
If so please advice how can I make the down payment (or if the fork has to be fully paid)
Thank you for any help,"
Never got a response, got a fox 40 float for a while and now I own a BOS idylle air rare for a month.
Would still like to read a long term review of the DVO by a real life costumer...
edit: it's a fair bit heavier than a fox40 though
Diamond, not emerald ;-)
AC on the Emerald is 574mm at 203mm of travel.
As cool as the green looks, it's just not for me. If it was a few years ago when I was really into my bright lairy colors then yeah sure, I'd be down for that! However these days i prefer things abit more low key.(compare the last two bikes in my profile lol )
On the flipside the black option makes the product look boring, cheap, doesn't bring out the amazing detail of this fork.
Gun metal & black /Pro-Circuit Gold/silver/root-beer mixed with the black lowers would have been a much better option, more neutral, professional and would suit pretty much any bike out there.
Anyhow great article and all the best to DVO, seems like they've kept true to their word, heard nothing but good things about them so far!
DVO suspension isn't cheap. If you truly believe in the technology, adjustments, and ride quality, than you will pony up and spend your hard earned money. As more reviews come out and more consumers have the product, there will be less hating and a lot more loving.
With 330cc's of oil in the damper and around 70cc's in the air spring you can go a long time between oil changes. It really depends on the total number of hours and in what kind of conditions. Oil changes for both the air spring and damper are easy and quick so we recommend it at least every six months if you ride a lot. Hit us up directly if you have any questions.
besides when I swapped my float for a Deville and this later for the mattoc I really got faster because of the better overall performance and control instead of diving through the travel and dancing on roots ;-)
Hope DVO gets really big and as soon as you bring the Bos Kirk Killer out,you'll have me as customer,too.
ride on!
gewichte.mtb-news.de/img/11/b4/50/11b45062d940ade8f58465fee49a96fd645489d2/large_1016306_635050566554502_787079540_n.jpg
sometimes its just not darn stiff enuf :-(
The torsionnal stiffness of the boxxer isn't a issue for me, only the "frontal" stiffness. I ride a domain because I don't want my frame to pass my front wheel when I use the brakes. (and because I love barspin)
But it's an issue with a 2002 shiver SC on my singlespped bike (It's fun but i can't go fast and be safe).
Thank's DVO for answering all the custommers questions so fast!
Anyone, other than google, know the total volume (cartridge, bath, ...) for the 40 and boxxers?
Don't get me wrong, I still want to try an emerald for my undead and I really want to try a jade too. Both will probably be secondhand due to the prices, but I still want to give them a shot.
