 yeaa, i love playfully designing stuff, just for fun. ya never know what you can come up with
  • 5 1
 For sure, that's how we all started way back in the day. Keep tinkering and keep designing things and you may come up with something can really add value to the sport!

 yeaa, first year mechatronic systems engineering has its toys we get to play with Wink
and that dual screen setup is like porn for engineers haha

 Grab a plastic bag. Fill it with water. Tie knot in top. Poke hole in bottom. Squeeze. This is your low speed damping. You can only squeeze so fast. Poke another hole and you can squeeze faster(backing off low speed damping).
Now jump on bag. Pop! This is your high speed damping. The low speed damping(small holes)where overwhelmed and the high speed damping opened up. If you had a thicker bag(thicker shims) you'd have more high speed damping.
Grab Mop.
This has nothing to do with the bladder Wink

 Hey DVO, y'know its great to see a company chatting with its customer base so much. Please make a short travel (120-150mm) fork, I'd jump on that so quick Smile

 My DVO checklist:

1) watch video of DVO setup new shop > check.
2) watch video of new DVO inverted mega-green prototype fork > check.
3) watch video of sweet new shock, ..but only available in plastic > check.
4) strap on green parts, bust out some banger laps with my buds, crack a frosty Pilsner to celebrate afterwards > ....... (crickets)....

Ok DVO. You've wined us and dined us. We're ready to put out. Let's go!
  • 5 1
 Soon! We want this stuff out too! Can't wait to get both the fork and shock dirty!

 really looking forward to the shock! sounds really gooowad!

 I wanted to order a Double Barrel next week but now i guess i have to wait some more time till this one becomes avaidable. So please hurry up!

 stoked for this shock but a question kind of related: if you want more stiffness in inverted forks why not just have oval stanchions?
  • 12 0
 very expensive to manufacture
  • 2 0
 isnt it the same idea as hydroformed tubeing on a frame? thats how they make all those crazy shapes on frames... what would be the difference in fork manafacturing?
  • 1 1
 not exactly, they would have to mold the lowers to fit the exact stanchions, and then it lacks the side to side stiffness that cylindrical stanchions bring to the table. and yea one more thing, how would you put it together? you need a locking screw cap.(needs a circular hole)
  • 3 0
 It would also be extremely hard to seal without creating excess stiction. Not to mention that unless the ovals were so big that you could still fit existing damper and spring designs, they would have to be profiled as an oval too.
  • 1 0
 it would be similar to hydroforming frame tubing, but frames don't have dust wipers, seals, bushings etc, nor internally mounted valving that would need to seal the inside diameter(s) of an ovalized tube
parts moving in concert is the source of the difficulty
  • 2 1
 ok points proven, I just saw some vintage cannondale dh bike on here a while back that had square stanchions but figured oval would be easier to seal, guess not!
  • 1 0
 also hydroforming will never get you a perfect stanchion.
  • 2 0
 i asked DVO this very question, they said #1 Ovalized uppers are too expensive to manufacture, and #2 they said their tests showed there wasn't much of an improvement.
  • 1 0
 Binding/friction.
  • 3 1
 Finnrambo: Non-circular stanchions would work well to improve torsional stiffness but getting everything to spec would be hard! You would need non-circular bushings and seals which would be really hard to manufacture, good idea though!
  • 2 0
 I was thinking triangle. The strongest shape Smile
  • 2 0
 You swine!I said the exact same thing to my mate about a month back,i drew up a few sketches and think they would look awsome.Being triangular the stresses would be equal on all sides.The internals could still be circular.Would be great to hear from DVO what they thought about this.
  • 1 0
 problem still remains of making a triangular stanchion and internals, also not sure about a triangle being any stronger then a cylinder in that type of application, sure a triangle may be more practical in some applications but it is definitely not the strongest shape, in most cases a circle is the strongest shape.
  • 1 0
 Triangles would only be stronger at 3 points just as a square is only stronger at 4. The flat surface that would be created by any box sections would allow greater deflection than a curved surface. Circular is by far still the most optimum shape that can be employed in the design of suspension stanchions as the loads through the tubes themselves have the same capacity no matter which direction the load is coming from.

Other factors create the higher loads in specific directions. Of course you could model the oval that would be optimised but load direction is very hard to analyze for every situation/direction and therefore cylindrical tubes have a factor of safety. Torsion across the surface of a oval shape I would image would also mean to optimise the design you would be looking at multiple thicknesses similar to that of the Thompson seat post internally which again would be greater cost and likely more weight.

This is theoretical mind since I don't have the software to start modelling this at the moment.
  • 3 4
 Since we're talking about shapes of stanchions, how about a hart shape? Would go great for the ladies. 3

 If I could get ahold of one I'd really rep these guys, I love the fact that they take so much input from consumers and really share the design/ testing process with us. I'd rep just for their customer service, the suspension would be a super bonus!
  • 3 1
 Thanks Camoguy1 ! We appreciate the feedback and one-on-one contact with everyone, it's really important for us!

 I liked this video, it was very informative
A bladder........ yes please.
Nothing beats taking your shock out and getting the "squelch" after you have oil that has gotten past the o-ring on the IFP chamber. Which in turn means you have air in the oil.
A vacuum bleed system for easy and often oil changes would be on my wish list, a bit like brakes have. Complicates things a little, but would allow for oil weight and mix changes, plus offer cost saving and convenience to the user by possibly extending the service interval
Using a similar system to the Avid bleed system would be great.

Can you change the shape of the rebound adjuster also. This can be a major pain to adjust on certain bikes.
Something simple like including an Allen Key hole in the centre of it would be nice so long as you have the clearance for the spring to be removed. Making the outside fit a tool would also be beneficial. I know that tooling costs money, but these are the things that make a difference in difficult to reach places with shocks.

 These guys at DVO are going to make quite some impact on the market... Might be my next suspension is a DVO, if I''m lucky!
  • 2 1
 Thanks Caiokv!
  • 3 5
 They certainly make a lot of publicity for nothing to show :Rolleyes:
But this is obviously what counts these days.
  • 5 0
 i'm gonna mount this on my pogostick and turn the rebound all the way up
  • 4 0
 So it just goes thud, and doesn't bounce.
  • 3 1
 could if he was a good 250 pounds...
  • 1 0
 No. It's pretty safe to say it'd bounce even less then.
  • 2 1
 agh different thought, figured he meant for faster rebound, be pretty cool if you could get a rhythm!
  • 2 1
 Might help with bunny hoping over logs!
  • 2 0
 Yeah I guessed he meant back the rebound right off, I was just mocking the whole internet debating trip. Rebound off would give more PO for the GO.
  • 2 1
 guess i shouldn't question the pros, but it seems to me like a bladder would be much more likely to wear out than a plate with o-ring. it looks like they provisioned for the bladder to be pretty easy to remove and replace, but its just more maintenance you have to do
  • 1 0
 hayes master cylinders.. yup
  • 2 0
 there's a bladder v piston argument in the motocross world--- a lot of different opinions about damping and cavitation and so on, but reliability of a bladder really isn't in question. Technically it should be more reliable as there is no friction like a piston O ring. The rubber doesn't degrade very fast either because it isn't exposed to UV, the biggest plastics killer
  • 1 0
 Avalanche shocks last forever with bladder. Less perishable, and less risk of oil/air mixing if piggy back pressure is neglected/too low. Less friction, less wear, win win.
  • 3 1
 The bladder only gets squished/compressed from the displaced oil so there's not a ton of "wear and tear" on the material itself. Moto shocks use a bladder system and we have yet to see one technically wear out.
  • 2 0
 ianmp uuhhhmm what argument in motocross world? name me a company that thinks IFP is better than a bladder. No top suspension company thinks a IFP is better than a bladder. IFP are considered a complete joke
  • 3 1
 Bladder systems are really awesome and companies like Avalanche has used them since day one. One thing for sure, they are more expensive to use but the performance benefit is worth the additional cost!
  • 3 2
 I don't wish to sound negative, but my advice is to wait a year after release before you purchase one, especially if you don't have money to throw around and/or are a long way from support. Real product testing begins when the production models go out to end users.

If you do get one of these, make sure you have a watertight warranty and live in an area where you can get a replacement Jade within two weeks. And keep your original shock as a back-up.
  • 2 0
 Why wait? I want it as soon as it's out, looks great design wise.
  • 5 1
 We plan to have a 3 year warranty on all our products so don't' worry! We will also do a lot of testing on all our products prior to release and we are using all top-notch components for seals, bushings, 7000 Series Aluminum, etc!
  • 1 0
 Stuff looks really awesome guys. One question/suggestion/request... I know it CAN be a pain, both monetarily and effort-wise, but are you guys planning to put up a chart with base tunes for various bike models? I see this getting tedious trying to cover everyone, but I found it very helpful to get an actual tested baseline from the professionals themselves for my frame from CC when i bought my DBair, rather than forum hearsay from randos. Tweaked the rebound to my liking slightly, but the compression was basically spot on for me. I'm sure trying to pick up everything from AM to FR to DH, and especially from boutique companies from Intense to Knolly to Cove, Devinci, Transition, etc etc etc... can get really expensive just to provide customer service unless you get demos easily, but... plans for this sort of thing?
  • 2 1
 Hey sweattpants, thanks for the input and we definitely plan to offer baseline tunes for as many bikes as we can. As you obviously know, its really important to have baseline numbers cause bikes utilize all kinds of different rates and its important to understand why a great shock can actually feel horrible due to a poor frame/linkage design. We plan to have a lot of tuning info on our site as products start flowing, stay tuned!

 I am really excited to see the new suspension in action. Hopefully once it comes out I can swap mine! And like a lot of people have been saying, I'm super stoked that DVO is taking the time to comment back on everyone's posts!
  • 3 1
 Your welcome TJ! Its awesome to have everyone in contact with us and hear the feedback. It's a real critical aspect for us and we will continue to have everyone involved as best as we can! Stay Tuned!

 Nice, elegant design and looks like the products are going to be very distinctive!. You'r also doing a good job of building a good impression of customer service with all your replies. I'm curious about the reliability/service life of the bladder design opposed to an O-ring and plate. I can see you still have volume and pressure adjustments on the end of the can, so that's a nice integration. Have you been able to test forces and oscillation on the bladder, or has this concept been used before?
  • 1 0
 ok, interesting. a quick google search has shown me the extent of bladder use in MX shocks. Yet again I'm surprised by how slow the slow trickle of technology from Motorsport suspension to high end cycle suss is
  • 1 0
 I realy hope DVO can make a go of this (it sure looks like they're putting their all into it) cause competetion in the suspension game is always a good thing. Marz have always been in another leagure in terms of plushness and seeing as DVO is a bunch of former Big M engineers I can bet their stuff is gonna be top-notch. Just make sure to keep a close eye on the QC department and these guys are gonna be the next big player IMO.
  • 1 0
 I can't wait to see your sponsored athletes! I'm sure you have already contacted a few and maybe even have a few signed on already. Looks like an awesome product to me! My only question is what happens if and when the bladder tears? Would it last as long as the O-ring design?
  • 1 0
 just a curiosity, but why did you all choose a monotube over a twin-tube design with a solid piston (ala Ohlins/CCDB)? is it a patent thing, or do you all feel that for this application, a monotube has performance advantages over a twin-tube? the only real advantages I can think of for a monotube right off are ease of manufacturing, marginally lowered weight and marginally more oil volume if you hold literally every other orifice and cavity size and component material/diameter equal, and that's about it, to my mind a twin-tube gets the nod just about everywhere else

 ooooooooooooo im used to a foes with a currnut so i want an air shock more than a coil i dont need plush i dont mind feeling everybump on the trail so i hope they make somethiong more suited for me

 Any chance the eyelets are the same size as Fox, so we can use their new Igus bushing mounting hardware kits with your shocks? Not to mention Enduro needle bearing kits, for those that want to spend the extra coin.
  • 2 1
 The eyelets will be the same and we are working on a new IGUS bushing system that is spherical and can be easily replaced by hand.

 Removable shim stack, Rad. Bladder, Rad. Can't wait to try one. Hope the oil channel to piggy back has a nice fat diameter to let oil flow freely.
  • 2 1
 Thanks NoSkidMarks! Tom did his homework when designing the Jade and we all felt a larger diameter shaft offers better oil displacement and damping performance. The main area of concern regarding larger shafts is the piston size and port diameters, we will also show everyone the dyno graphs soon.

 oooh a bladder and easy to tune, looks like someone's finally catching up with Avalanche lol - will it come in custom sizes too?
  • 2 1
 Avalanche has been using a bladder since day one and kudos to them for sticking to solid moto based designs! Regarding custom sizes, let us know what you are looking for and we can see if will have a shock that fits your needs. Cheers, DVO!

 just interested in 190mmx57mm and [I think] 12.75"x3.5"... first shock was a unique configuration for my old Orange, which is still the best bike I own! The other is for Foes frames, just interested if you guys will be making one for them?

 For actual suspension people: How do you go about bleeding a bladder reservoir style shock vs a IFP?
  • 1 0
 Push bladder into oil, let access oil overflow.
  • 2 1
 Yup, its a lot easier to bleed a shock with a bladder and the stiction is significantly reduced.
  • 1 0
 How do you do it? You can't just push it in without cycling the shock to clear the circuits...or do you just do that then put the bladder in? I find it incredibly easy to bleed IFP-res shocks. I understand the allure of less stiction etc. I am imagining rolling the bladder in like Hope brakes which seems inaccurate.

I know you know what I'm talking about. The whole "tap res with your palm" thing to cycle the oil and get rid of air bubbles. How does that part happen, do you just leave the oil a little lower? I've never worked on moto shox.
  • 2 1
 Hey kmg0, its kinda hard to explain in words but we will have a cool video explaining all the details of the bladder and how to insert it into the reservoir. After the main shock body is bled and the reservoir body must be vertical and full of oil, then the bladder is inserted (allow the oil to spill over) and then tighten it into the reservoir housing. The bladder itself (like moto) is quite sturdy and not like a thin rubber material used in brakes.
  • 1 0
 Ah, okay... I was wondering if you bled the body with the bladder in there already, which seemed strange. Never dealt with one, figured it was pretty similar. Cheers. Good luck!
  • 2 1
