It's been some time since RockShox unveiled a completely new model in the shock department, as the past few years have seen more incremental - albeit significant - updates to the existing SuperDeluxe. That changes with the announcement of their new Vivid, an air shock squarely aimed at the gravity-oriented side of the sport.
The Vivid was designed ground-up to offer the best downhill performance the team at RockShox could deliver, with a new architecture and damping platform to achieve that goal. They promise coil-like sensitivity with all the intuitive adjustments their current lineup is known for, but does that shake out on the trail?

rockshox.com Vivid DetailsIt's been about a decade since the Vivid last saw an update, with the prior generation ending before suspension manufacturers made the switch to metric shock sizing. That prior generation was unique for RockShox in its use of dual rebound adjusters, but that's far from the only difference to the new model. The 2024 Vivid is implementing some very clever designs that allow it to achieve the performance goals laid out, while hopefully remaining far more durable than the predecessor.
The majority of the novel technologies for the Vivid are wrapped up in what RockShox is calling TouchDown technology. TouchDown is a position-sensitive damper that allows the shock to work in three distinct phases, with characteristics optimized for each section of the full stroke of travel.
Think of this sequence in accordance to the sag gradient.
0-10% This is one of the more unique aspects of the Vivid, as in this first increment of travel the oil flow actually bypasses the main piston compression damping, instead flowing through an array of holes only located in that phase of travel. The purpose here is to make the Vivid's initial stroke as supple and sensitive as possible, without affecting the remainder of the travel.
10-80% You'll be spending most of your time here, and this is where the Vivid should feel more or less like you'd expect. The air volume of the shock was maximized in order to give this middle block as linear a feel as possible, with the ability to add progression via Bottomless Tokens. This is also where the High and Low Speed Compression adjusters do their work, providing the ride characteristic that best matches your frame and ride style.
80-100% In the final chunk of travel you run into the Adjustable Hydraulic Bottom Out (AHBO), which allows the user to tune the bottom-out resistance at the end of the stroke. This separate circuit has a different feel from the ramp-up you get with volume spacers, and is more of a soft catch that slows the shock down in that high-load moment.
You have to drop the air can to add or remove volume spacers, but the main adjustments can all be made externally. The LSC adjustment is made via a knurled knob, while the HSC, AHBO, and rebound all use a 3mm hex. Luckily, the rebound adjustment knob contains a hidden 3mm that you can simply pop out and use to make the other adjustments - a clever detail indeed. While RockShox only gives access to low speed rebound externally, you can alter the high speed rebound via the internal rebound tune. Definitely less convenient than an external adjuster, and best left to be done by professionals, but know that it's an option.
The Threshold (aka climb switch) lever is quite firm, both in physical feel and in how stiff it makes the shock. I really only used it on a few paved climbs, but was happy with the amount of support it provides. If you happen to like a quite soft setup for the descents, the Threshold should still be able to hold you up for the pedal back to the top.
One last detail worth noting is the service interval on the new Vivid. Where most shocks call for a basic service every 50 hours, the Vivid specifies a 100-hour interval before you have to worry about tearing things down. Of course it's always worth taking such claims with a grain of salt until they've been thoroughly tested long-term, so we'll see how things shake out.
Ride ImpressionsI've had the opportunity to ride the new Vivid on a few bikes at this point, but the majority of the testing has taken place on the Santa Cruz Nomad and the Yeti SB160. Two very different bikes when it comes to how they drive their shocks, but equally capable in rough and challenging terrain. They even use the same 230x65mm shock size, albeit with very different tunes. This made for a good spectrum to compare within, and see how the shock performed given the differences in frame design.
I'm happy to say that the main commonality between the two was how well they played with the Vivid. Both bikes retained an active feel, cycling through the suspension smoothly and predictably as you'd want them to. This allowed for excellent grip and bump absorption, while still providing enough support to push against in compressions and help keep the ride height neutral.
A satisfying realization was just how different the Vivid's settings were between the two bikes, and I was able to find an optimal setup on both after just an afternoon of bracketing the various compression settings. Like the recently updated SuperDeluxe, each position of compression adjustment provides a clear and discernible difference, with the visual reference helping you clock between multiple settings if you want to change certain clicks for specific tracks. Bonus points to RockShox for the continued use of the sag markings, now I just want them to release that patent so every shock on the market can be that easy to set up.
The final accolade worth pointing out is just how quiet the shock is. This, coupled with the very muted feel it provides, helps the bike fade into the background and keep you focused on the trail ahead. Some shocks have a distinct feel or characteristic, but so far I'd say the Vivid's strong suit is just how neutral it can feel when you get the settings dialed in.
LineupThe Vivid comes in 5 different spec levels, with the Ultimate aimed at the broadest part of the market. This is the primary aftermarket option, with the DH shock obviously focused more on bikes that are entirely gravity-fed. The lower 3 specs will likely be more common on OEM spec-sheets, and can be modified into the Ultimate range of adjustment with some aftermarket parts. If for instance you have a Vivid Base but want the full Ultimate package, you will be able to buy the TouchDown RC2T reservoir upgrade and bolt it in place of the Base one. This upgrade reservoir costs $235 USD, and could be a great option for bikes that will be coming with the lower-spec Vivids down the line.
Another aftermarket element to the Vivid launch is the introduction of RockShox's Bearing Adapter Kits, which can replace the standard DU bushing mount with bearing hardware, where frames allow (8mm ID x 30mm hardware required). This kit also fits the 2023 SuperDeluxe Coil shocks, adding some tuning options to the existing lineup. Bearing mounts can help reduce friction in the linkage, and improve the sensitivity of certain kinematics quite a bit. The Bearing Adapter Kit costs $30 USD.
We'll be spending plenty more time with the Vivid on a variety of bikes in the coming weeks and months, so stay tuned for the long term thoughts. In the meantime, the short story is a positive one, with the Vivid upping its smaller SuperDeluxe sibling, and posing a real challenge to the Fox Float X2.
What has actually changed on the 2024?
NEW base valve piston design and compression tune for increased damping performance and improved sensitivity
NEW bearing housing seal package virtually eliminates possibility of aeration
NEW scraper seal for improved durability
NEW more robust eyelet design on trunnion models
NEW 7000 series shock body on all models
NEW hard chrome damper shaft finish for increased durability
MCU bottom-out bumper for end-stroke progressivity
Good to know. Though I remain skeptical.

Especially bikes themselves, for example Spezialized made Ebikes in 2020 that litearlly broke engines on every single ride. It was absolute trash, and a abuse to the customer.
Does that work even if it's Trunnion?
i was doing my warranty
Not anymore. Serial numbers only from here on out. On the seal head.
The wiper seal new and properly serviced shock -will allow fresh oil / lube to bypass the wiper seal coating the stantion; so that would be considered a leaky bad seal according to you
A better solution is just use a microfiber rag to wipe clean the stantion and wiper before each ride, or at least when any buildup occurs, then service using a new kit, with recommended fluids, at the recommended intervals or when stiction is evident.
If you're riding over 100 hrs a year you should definitely learn how to do a lower service on your fork, then it just cost $5 in materials for a bulk foam ring and some oil. It only takes 30 minutes once you've done it a few times and is very simple.
It also definitely makes a difference in performance and longevity.
People will spend agonizing pain and energy installing tire inserts and deal with a possible trail side tire issue, but won't invest in the basics of a simple service is baffling to me and express's idiocracy even tho the attended colleges and have jobs and families.
And yes, i have in the past, gone without doing a service or had these failures but learn quickly to address them when needed and reap the noticeable fruits of that labor.
TOO MANY times i have been riding with people that have the (never service mentality) and the oil is oozing everywhere around the seals collecting dust and mud like a butterfly net !
I'm not complaining about having to maintain an investment, It's a necessary measure to make the parts and equipment work as expected. Imagine if you need to service the front and/or the rear strut/shocks on your car every 50-100 hours? LOL
If an automobile manual says to use 5w30 oil, you only should use that specified oil, not 10, not 40 but only 5w30.
They designed the vehicle and know better than the average brain, what is fitting for the vehicle. IMO this applies more today with high end expensive suspension, than did in the past and should be done as specified by what the engineers have designed and tested for their product. Thats all.
It doesn’t need to beat the previous Vivid, it only needs to beat the X2
Talk to any mechanic/machinist, they laugh at the ridiculous prices of Fox’s ifp depth setter and so on…
Snap your fingers one more time and make my favorite PB editor appear!
Everyone was so stoked to se the return of the Vivid Air. I hope it is vastly improved, because I recall it being a bit of a dead unsupportive turd previously.
The spring force chart speaks the truth, a coil is more sensitive off the top and much more supportive in the mid stroke. Add a good bottom out bumper or HBO and that's all you need. #coilforlife
More than likely service intervals has dropped and changed due to modern bikes and users being more aggressive and less service conscious, resulting in excessive wear and tear.
Note the writer saying not to take as gospel, in the UK and Scotland thoses service intervals WILL drop substantialy due our shite weather and "most" peoples lack of service knowledge /acceptance.
Old one was a love hate relationship.
BMXers be like: hold my beer.
I know the real world doesn't do linear deceleration but it was fun to punch in the nrs. Would be even more fun to compare to real data.
RS updated the Lyrik's B1 air spring to the C1 because riders complained that it did not allow for accurate sag measurements. It's no coincidence that the new Lyrik & Zeb don't have sag % marketing on the stanchions.
My vivid air lacked damping (I'm heavy --> high pressure --> closed rebound still too fast) so during a service I asked for a -slightly- heavier oil.
It came back too harsh, by a lot. Never had I lost pedals so much in rooty sections AND never had I felt that first ground contact after air time, so much.
So yes, no compression damping in the first 10% would have solved my 2nd issue, so I bet it's only positive here.
Externally adjustable HSR would be more useful.
If you make it resist movement more, it's already resisting movement. Which means you will be generating forward speed with your pump inputs, rather than just compressing your suspension...
It would be great if pinkbike could get some lighter riders on some of this stuff to see if it is a viable alternative to coils for lighter riders.
The fundamental problem with air springs, however, is still just the friction inherent to airtight seals. I'd be really curious if RS figured out a way of making the frictional force "light enough" for light riders to use actual air pressures instead of relying on seal friction for support--which is what you end up doing with super low PSI rates in air springs.
Also, you guys are crushing it. Pinkbike has totally stepped up their game recently. Thank you all so much.
Have you ever tried custom tunes of the damper? (shims, valves and or oil).
On the older RSD, if you weren't able to use full travel with the normal air can without any positive spacers, the megneg can would make it even harder to use full travel.
I don't care what they called whatever you're referring to. Bigger air springs, especially with large negative volumes, are closer to linear, with less steep ramp up of the spring rate at the end. Smaller volumes ramp more, hence volume _reducers_ being added to increase progression of the spring rate. A light rider would remove the reducers, or get a bigger can to maximize the volume and minimize the change in spring rate through the stroke, so their smaller mass could still push through the always increasing (but less with bigger volumes) rate near the end.
Damping is a very different story, ideally you would want to adjust the oil viscosity or at least the damper settings proportional to air pressure to achieve the same characteristic. So on suspension that doesn't have every valve adjustable, lighter riders will be overdamped on hsc and hsr. Compensating that by lowering the spring progression is a stop gap solution but perhaps conceptually more simple than switching to a different oil that isn't factory approved, or having the shim stacks rebuilt.
However, air has a ton of friction, and the pressure/spring rates that make those frictional forces a less than significant portion of the overall spring force tend to not work for some people on the lower end of the weight spectrum.
The frictional force as a total percentage of spring force is way higher for a rider with 150 in their shock than someone at 250.
So lighter riders tend to do better with less "progressive" spring rates in their air springs because the frictional force is so much of a higher percentage of their spring rate.
There's also some damping caused by the air compression not being completely adiabatic but that's minor compared to what happens in the damper so I'd be surprised if that would play a role.
I'm a scientist and not an engineer, so I tend to overlook the non-idealities that are abundant in the real world, and it's my experience that when you look close enough you find the explanation for why people do things with their settings that don't make sense at first sight. So I'm not trying to say people are doing it wrong. Just looking for the explanation.
I do think one trivial explanation might be that lighter riders tend to be less powerful and therefore ride more smoothly even if they ride the same trails at the same speed. It would be interesting to compare the degree of progressivity in the forks of people like @JesseMelamed and other hard-charging light riders to their heavier colleagues.
It would be nice to be able to have lighter riders get the benefit of air's tuneability without suffering so much from the higher effect friction has on lower PSI settings.
Sheesh.
Yes, when the tires slip off the ground they move past sag towards top-out, and then when they hit again they move past sag the other way. But the average is going to be close to sag, or deeper, for a "skipping along" situation, not hovering around top-out. If you're going slow enough and the holes are big enough that your back wheel fully extends on every skip, maybe you'd notice a little less impact for the very initial hit on each skip, that is once any stiction and/or hysteresis of the spring is overcome.
Ultra Funny
For people buying aftermarket shocks, is the recommendation to always take it somewhere to get tuned, since most stores and shops don't sell it off-the-shelf shocks for specific frames?

When an air shock finally performs above a coil, I'll give a shit about air.
#coilforlife
@pinkbike - Can you start doing some data driven testing with actual instruments that can tell us what is happening on products like this? Paging dan roberts or seb.
There are serveral different tunes offered:
Rebound R25 R55
Compression C26, C30, C34, C37, C40, C43
Yup, this one doesn't mess up your spring curve. Volume spacers are such a hack
