RockShox MegNeg Air Can Review - Vital MTB Advanced Class
Вставка
- Опубліковано 1 січ 2020
- Find yourself wanting more out of your rear suspension? This RockShox air can kit will transform the way certain bikes ride and provide you with the ability to tweak the shape of your air spring.
Introduced alongside the Lyrik Ultimate fork and Charger 2.1 damper update, the MegNeg air can kit more than doubles today's already large negative volumes. This results in a noticeable and tunable boost of mid- and end-stroke support (and a lot more pumping). Join Vital MTB's Product Editor, Brandon Turman, to learn how it came to be, what the tuning process is like, the upsides, downsides, and an overview of what types of mountain bikes will gain the most from the MegNeg upgrade.
MegNeg Air Can Highlights
- Allows you to tune negative volume with Bottomless Rings
- Provides 64-111% more negative volume than a standard air can
- Compatible with RockShox Deluxe and Super Deluxe shocks
- Available in 550, 650, and 750 kits to fit Metric shocks with a stroke between 47.5-75mm
- Includes air can, Bottomless Ring volume spacers, seals, grease, oil and decals
- 325psi max pressure rating
- MSRP: $90 USD
The MegNeg inches RockShox air shocks closer and closer to that coil feel while maintaining the ability to make quick pressure changes and adjust bottom-out support. It's fun to wrap your mind around and experiment with, seeing what works and what doesn't work for your bike and riding style specifically. There's a lot of tuning capability here, and this product will help people create more enjoyable rides.
If you are constantly banging off the bottom of your bike's travel, have that sucker stacked full of volume spacers, run the lowest suggested sag value and still aren't getting the support you're after, you absolutely want to consider the MegNeg.
You can tune compression stacks all you want, but addressing the spring curve is always more impactful. This is an excellent upgrade for a reasonable price and will make a big difference on bikes that could benefit from added mid- and end-stroke support. You've got to be willing to do some back-to-back testing though!

This video is dialed. Straight and to the point with tons of useful information 👌
Cheers!
it is!
Solid product, impressive performance gain of the super deluxe, feels so good now my ride. Settled with no tokens and 2 bands to achieve 30% sag. Increased pressure to an additional 50PSI. Also, incredible bottom out resistance but still using 95% of the travel.
Just assembled mine last night. Hoping for this exact result!
Awesome video! Really detailed and explains Megneg and if it’s right for your bike.
Thanks for the good info, really considering a meg neg
Thanks. Got the MegNeg for my commencal furious and it made a massive difference once I got my spacers dialed.
I have the furious too! And am about to Install , what are you’re settings you’d recommend ?
Awesome video. Very cool that Rockshox took the initiative to experiment so radically with their shocks.
No. They copied the DVO topaz that has been able to do the same thing with both positive and neg air from the beginning.
@@davidsilvas9441 Thanks for the info. I'm now interested to take a deeper look at the DVO shocks.
Great review!!! Thanks Vital.
Well I guess I'm getting a megneg! Thanks vital mtb
Works wonders on my 2018 trek slash. Upgraded to a used 230x60 ultimate deluxe to achieve 160mm of rear travel and added the MegNeg. I’m 6,1 180lbs riding a size large Slash. Big wheel, small frame concept since I ride aggressively on technical trails. With the MegNeg I’m running zero tokens, two bands and 220 psi at 30% sag. It keeps up with my 170 Lyrik with Push coil conversion and their damper. HSC is nearly full open, I run about 5-10 clicks of LSC depending on how flat or steep the track is. LSC on the shock is typically fully open unless I’m running a track that has big G outs and berms. Having the mid stroke support with sensitivity really propels you forward rather than into your travel resulting in less speed
Excellent Tutorial! Looks like a great option for the Bronson V3 due to the Bronson's linear nature. However, a Fox X2 will most likely be the better option for the BV3, but at a much higher cost though.
Excellent video. Completely explained every detail. Thanks!
thank you guys for amazing video. I ride Giant Reign 29 thx to this video i went for MegNeg last year on my Deluxe+ and yesterday 6/6/22 went for Super Deluxe Ultimate with the MegNeg. I know there is new gen out (2023) but i did charger 2.1 upgrade too - not possible to upgrade my fork to Charger 3.
This shock tracks like a beast - 1st impression on the trail - "Is my rear end detached, too soft, loose or what is happening... while it tracks like a knife thru the butter" downhill feels so planted without too much skipping and wheel being in the air, uphill tracks great too.
Overall - upgrade to top of the line (still like 10 days ago) front and rear makes your ride a "new bike" and lot safer too.
What setup do u ride on megneg? How much spacers in + and - chamber? I have Super Deluxe Select+ on my Reign 2 2021 and Lyrik fork.
@@CuferM hi. I run 1 spacer and 2 bands in MegNeg - but feeling like just one band in MegNeg for more support.
Bturman is smooth as butter!
Great video. Good work.
that trail looks sweet
Good ole Nachos in COS
Great video bud
Finally took the plunge and got a megneg. Took the recommendation of another UA-camr and installed megneg with 1 rubber band. Noticeable improvement. My bike is heavy and the rockshox deluxe select I have has no lockout and is always fully open. So when I pedal, there's crazy bob and always feels like the rear is sagging when I'm pedaling up and over rocks. Now the shock has much more support while retaining that top stroke plush. But it still suffers from that sag just a little bit. Thinking about going zero bands now. I wonder if it'll be too harsh on the chunky stuff. Something to note: I added 60psi on top of my normal pressure to achieve 30% sag!
What bike do you have?
I added the megneg yesterday on Bronson V3, I just guessed and put 2 and 2 with 25% sag @ 250psi. I'm 67" 165lbs with gear.. So much lively and better support and feel then stock. A little stiff so I'm still experimenting.
Thanks for this vidéo 👍🏼
Very welcome!
Hey I've ridden there! Forgot how awesome Colorado is..
@vitalmtb. Did i just watch you say the meg neg wouldn't necessarily help on a bike like Sam hill's? (One of the pre release testers)
Hi very good video,i want to mount Megneg in my focus jam 6.7 nine.
Focus uses FOLD linkage system on his frame and have a degressive to progressive curve like the third graphic in your video.
I want to limitate a little the bottom out and have more mid-stroke support but i don't want to have less feeling on the high of the shock.
I thought to remove just one token on the positive and add 2 tokens on the negative of megneg for a first point of start.
Do you think this first setup up may be correct for a starting point? Thanks man😉
What do you recommend for bikes with progressive curves, like a Rocky Mountain Altitude? I have a DPX2 but want better small bump compliance.
I wish Rockshox would use bands that didn't require you to remove the shock to install them like DVO uses. You just drop the can and remove or add a band/spacer. Really great job on this video. My friends say it works great on VPP suspensions.
Could you load/store all the bands on the outside of the can, pop the chamber open on the bike, move a band into/out of the chamber and close the chamber back up...all while the shock is still on the bike?
@@mmodtomic7119 You can do it with the shock on the bike without removing it.
@@travelthenarrowtrail8660 Your previous comment stated: "I wish Rockshox would use bands that didn't require you to remove the shock to install them". I don't understand your reply.
@@mmodtomic7119 Sorry, I meant to say with DVO shock you can install bands without removing the shock.
I was tempted by the Meg neg for my nukeproof mega 275. Instead upgraded my stock super duluxe with the vorsprung upgrade. Absolute night and day, does what I want it to and some. Maybe do a Meg neg vs vorsprung duluxe as the next video?
damo mega275 interesting , I’m on a 290 nukproof mega , only had it since November , and am a bit confused whether the megneg is worthwhile for this bike , it feels so perfect when descending, but maybe a bit flat , lacking support when pedaling thru flat areas
I’ll agree with Cam Wells, same situation. My Mega 275 feels a bit wallow-y around sag, which is noticeable when pedaling around flatter terrain. Descents are great though. I’m curious to hear how you’re getting along with the Vorsprung upgrade, and what it added to the bike?
Looking at the leverage curve and anti squat, it seems to me that a Megneg or a coil shock would help provide more mid stroke support and maybe a better pedaling platform. The data makes me think the bike is trying to push me towards sag since the initial rate is regressive and subsequently progressive, and that’s where the bike has the highest leverage and so is most likely to move. Maybe going down from the stock 32t chainring to a 30t would help as well?
So no good on Jeffsy, what about a simple stock can upgrade - inside? Can spacers be added? Basically i'm looking for better top end suppleness. For me, once the bike gets active and deeper into travel its fine. Just a bit firm up top, which for pedaling is great. Solid shock for me, had the coil but it was clunky, noisy, and heavy, but performed really well.
is this also for the one without the external oil can?
I'm riding a Patrol as well. Would the MegNeg be a good upgrade for a heavier rider due to the ability to hold higher air pressures?
So how does this compare to the X2? And I'm building a megatower I weigh 225 plus 20 to 30 gear. Should I stick with this and add megneg or go X2. I like a poppy bike.
Hello how would this work on a 2020 fuel ex trek ?
graet info on this video, thank you . can you share some more info on the positive tokens used ? what was the initial set up and if it was changed ? i currently run about 165 PSI with 3 Tokens in my super delux -- still getting frequent bottom outs (no harsh ones- good control but more frequent then i would like)
The positive volume spacer was not changed on our test bike.
2016 canyon strive with debon air plus rc works with it?
Okay, but what a about the shock’s shimstack? They are in order for a different air can and with the megneg I think they will need to be put in another order?
PS: sorry for my bad English I hope you understand my question
How many tokens did you end up running in the positive side? I’ve got the gnar dog +1 on the same patrol...
Not sure if this is a stupid question but can you upgrade an in line shock ,without a piggyback, with a magneg. Thanks
Can someone tell me if the bottomless rings used in the megneg are the same as the ones used on the vivid air and monarch debonair :).
Hi, how many tokens and negative bands would you recommend?
Great set up suggestions! I love been riding the megneg for about a year and the thought of going back to the regular can makes me cringe. Quick question: do you recall how many Gnar Dogs (‘tokens’ (not bands) ) you’re running in the main body of the shock?
The instructions tell you to remove 1-2 tokens from the positive chamber because the megneg causes more ramp up on its own. For me removing 1 token from my previous was perfect for my commencal furious. I also found three bands was perfect. I figured this out on my MTB hopper and curbs and then on the trail it turned out it was right on.
Is there one for Fox DPX2?
I got one for my 2018 process 153 and it’s a world of difference. I run two tokens with no bands. If you’re use to air it will feeling very dead but if you’re coming from coil like I was it feels right at home.
Michael Marley interesting because the 153 is supposed to be pretty progressive. Maybe thats why it was better with 0 bands. Would be fun to give it a try
Would it be a good upgrade on a 2021 Specialized Enduro Comp?
I love eggnog now I want that magneg
what gilet has brandon got on in the vid?
I just set up my shock last night and I according to Norco ride aligned I added 220 psi to get 30% sag and I weigh 160lbs
So for a Rider around 240lbs. I am lost on how many bands I should run at this time I am running 2 but it doesn't look like I'm using all of my travel. Still have about 10 to 15 percent left but set it up at 30 percent sag. Please help
Damn what trail is that at 3:19? I wanna go there...
it looks like the fox float x from 2017, just that the fox only had positive volume spacers. The fox had to much negative volume. I had that shock last summer. It was so smooth, it was perfect, but i was always botitming out, That's why fox change it to the DPX2, it has less volume negative. I think the rockshox one is cool because you can change the negative volume.
@@piciu256 ok. thx for the information. did not know that, anyway the float x it felt good just a lack of support.
I want to swap my 36 rhythm and DPX2 performance that came stock on my bike with a ZEB ultimate but don’t know if the super deluxe ultimate with a megneg would be a better option on my status 160 (FSR link obviously) than the DPX2. Or should I use the money and just get 38/36 factory and keep the DPX2 🙃😂
Having the same thoughts right now. Same bike. I wonder what did you end up with? Thanks.
So did you leave the same amount of spacers in the positive spring? I find the same thing on my patrol, even at 22-24 and max spacers i blow through the mid stroke but then only get full travel on fuck ups basically, and less spacers and less sag makes small bump terrible.
Yes, the positive volume spacer was left the same on the Patrol. It may need to vary on other bikes.
What's that handlebar you have there?
What you thing about dpx2 for trsnsition 2020 frame
Would this work on a 2019 capra?
Are there some guys how put the new megneg on a santa cruz v4?
So adding bands reduces the midstroke support and as theres less total pressure ? And running less bands will result in greater mid stroke support as theres higher over pressure?
Correct.
Great video , only part I’m confused with , is it suited to my bike ? I’m on a 290 nukeproof mega
How do you know if your bike is has a digressive, progressive, less progressive, etc. setup?
Love my megneg on the 2019 giant trance. Feels bottomless and predictable after a little tuning. I’ve had it for about 7 months in Colorado now, tested on every type of riding including park.
When tuning, I had to run the maximum spacers in both chambers. (Well, one band away from max spacers in negative chamber and Full max in positive.) The change in positive spacer was absolutely key, so I’d plan on experimenting with it if you want to ensure happiness using a megneg.
Pedal Bob is more pronounced with a megneg, but that’s what the 3pos lsc lever/“lockout” is there for. Even then, I honestly climb open on most trails.
Overall it’s seriously awesome. Midstroke is far more refined. And the bottom out resistance is amazing even at trestle. Traded bikes with my friend who rides a Bronson for a lap at trestle who described mine as vague. But I found his to be far too rough and choppy. So much feedback it was absurd. The megneg just mutes little stuff out at slow and high speeds. The ramp up is on the money. Close as I’d ever want to be to a coil. And on bigger hits, satisfying and predictable are the only way to describe it.
If the megneg was any older, I’d be appalled that this isn’t standard issue for many frame makers bike’s out there today. There simply must be bikes out there which are better suited with a megneg to optimally tune in the suspension. So they aught to be leveraging it soon.
Ftr, I’ve also a/b tested the dpx2 and super deluxe. With and without megneg. The dpx2 is just not up to speed with a superdeluxe. Love fox forks, but the super deluxe is king right now and worth making the most out of. Especially if you need to service it anyhow.
This is going on my '18 Trance this week, Ill start off with the recommended 3 bands in Neg and Max in Positive. Im coming from a DVO Jade and wanted something different with a similar coil feel. Any other thoughts after another year of riding?
@@mutantsatellite nothing really. But I recently took a spin of the new trance advanced x at a LBS. It was equipped with a DPX2 and it was just zero fun. The entire bike failed to impress. Partly because the stem was at the top of its stack, but there still weren’t any redeeming qualities shining through. It was a total bummer for me, even though it makes me appreciate the 27.5 trance even more. I’m also running a 170mm fork. The whole setup of my bike feels absolutely optimal.
@@zanetaylor7 right on!! Yea I’ve got a 160 fork on mine and running a mini enduro build. I do enjoy the 27.5 as more and more are going to 29 only. Thanks dude
I put a Megneg on my Evil Calling and it s a solid upgrade. The shock should
Come stock like that, it s so much better. It grips more, it s bottomless and feels even plusher .
thinking on running it on my calling as well , can you comment on the pressures u r running before and after ? and how much tokens were u running with the standard air can ?
AMIR ZEMANEK I don t remember the exact pressure, however I was running 30% sag with one token. I now run 30% without the token and the Megneg is empty. It s just really easy to set up and it feels really good. You should really go for it, you won t be disappointed.
Thinking of upgrading the Debonair Super Deluxe on my Evil Calling. How many bands did you use?
aughtrnb no band for now
@@asselinpower Awesome thanks for the feedback!
What handlebars?
What are those handlebars?
WHAT TRAIL IS THIS IT LOOKS SO GOOOOOD
That's Nachos www.trailforks.com/trails/hummingbird-trail-nachos/
Nachos at Ute Valley Park
Perfect for a norco sight
I second this. It gave my 2020 Sight A1 suspension the bottom out resistance that this suspension lacks as a stock
@@eden4x4 How many negative rings are you running?
@@AustinSue 2
Note for regressive to progress. frame kinematic riders: Nuke Mega 290, stock shock: 260 PSI (no tokens) for 30% SAG with 105 kgs bw. After Megneg: 325 PSI = 31-32% SAG, without tokens, 3 neg. bands. In future I attempt 1 pos. token, because its help me with about 25 PSI more pressure in pos. chamber. Over 250-260 "stock" PSI need more 25-27% pressure for same SAG!
Good luck with those seals.
Wow that's interesting, I consider to buy one for my Transition Sentinel instead of a Coil Shock 🤔
I designed the megneg while riding a Sentinel. Coil on the Sentinel works but you need to run a stiff spring and around 20% sag or else you're on the bottom out bumper half the time.
dcamp29 or run a progressive spring.....I have a super deluxe rct with a mrp progressive spring on my 17patrol and the only thing I miss is the feather weight of an air spring. I may upgrade the OEM airshock with a megneg for bikeparks
I've got the cube stereo 170 2021, and it's lacking both mid stroke and bottom out support. Should I buy the megneg, or just mount it in the coil shock position?
I've got the 2021 CUBE STEREO TM with the Super Deluxe, new bike, bottom out is my issue. Did you upgrade yet? I'm seriously considering going to the Megneg. 220lbs. on XL frame.
Absolutely love the CUBE, just like the rear shock...
@@scott9660 hey, i havent upgraded the shock with a megneg, but i bought a 28x8 bushing, to mount the shock in a more progressive position. I think volume spacers will be good enough. Let me know if you have any other issues with the bike.
@@iliyadavoodipour258 Iliya, that's a good idea. RockShox site states Megneg not compatible with Super Deluxe Ultimate w through bolt attachment. Hmmm...
How will it perform with the Evil Calling?
Good.
How would this perform on a Ripmo?
Probably really good - would give it more mid and end of stroke support while making the beginning stroke slightly more supple
Interesting for sure. So you take the DVO Topaz concept and make it work on a RS for $90? I guess that's better than forking over $500 for the DVO Topaz.
Similar in its ability to be tuned. Larger volume, however.
The negative chamber on a topaz is tiny compared to the megneg. Topaz is a great shock though.
What are those handlebars???
Those are the Fasst Flexx MTB bars. Learn more here: www.vitalmtb.com/product/guide/Handlebars,38/Fasst/Flexx-Enduro,24182#product-reviews/3503/expand
Is this recommendable on a nomad v4 ?
Jep! Interesting for me too! Also the V4 and it feels like to low on pressure, but has 25% sag for me. Even on smooth terrain it's nearly at the end of its travel.
Any ideas?
Wanted to test out a thicker Damperoil. But with this, it opens a new Option.
i would like to know as well. anyone running on the nomad v4?
If the megneg makes the shock more linear then wouldn't that mean it suits more progressive suspension designs? You said it wouldnt suit a Capra because of its progressivity but that doesn't sound right.
Piotr Sulej does it reduce the volume in the positive chamber somehow?
"Closer to a coil" with regard to the initial and mid-stroke. You still retain the ability to use volume spacers to increase end-stroke progression in the shock. It may be difficult to use full travel or you may feel too many bumps deeper in the stroke on more progressive bikes with the MegNeg.
Better way to think about it is, the shock is still progressive, but the curve is more straight rather than hammock shaped as it goes up.
So you know if the megneg would work well on a 2019 trek remedy
I also have the 2019 remedy with the super deluxe thru shaft, i really wanna know if its a upgrade for my shock..
Piotr Sulej where would you look for leverage curves can’t find them online for my bike
This website is a good resource for looking up close approximations of various bike kinematics: linkagedesign.blogspot.com/
Nicky Stuer ordered one for my remedy will tell you how it feels when I get it
Nicky Stuer just got mine run it with one band in and took out 1 volume spacer at the same pressure turned my bike into a mini dh rig incredible upgrade total transforms the bike get it
What the hell type of handle bars are those?!!?
Blair Aitken Fasst Company.
MegNeg air can is not compatible with MY21 Super Deluxe Ultimate ThruShaft.
When I see this I'm so happy I have coil :D
would it work well on a Santa Cruz bronson v3 ?
I've been trying one on my Bronson V3 for a couple of weeks.. still experimenting but already noticeable improvements. Like Brandon says in the video, be prepared to do a lot of tweaking and testing to get the most out of it.. I'm in that process now.
@@greganderson9618 How many bands/token are you currently running?
@@greganderson9618 Hi. What shock do u use? I have the rct
Mike P.
I started with 2 bands/2spacers @ 265psi (non-megneg psi + 20%). It was very supportive but spikey in the last 3rd of travel.. ended up removing 1then both + spacers and increased psi to 270. Much smoother but using full travel a little too easily. I decided to start over and start at the “extremes” of bands with no spacers, actually measuring sag accurately (PITA on the Bronson). Once I get the beginning/mid stroke how I want I’ll add spacers if necessary to control bottom out. I’m currently on the first step with 4 bands/0 spacers @ 275psi (30% seated sag). First couple rides, it’s a little firm off the top, mid stroke is good, very smooth use of travel on big hits/drops but left - 10mm (18%) shock travel unused. Next step will be with no bands.. and we’ll see. I weigh -215 geared up btw.
el G
Mine is the basic R.. no lsc or lever.
Anyone try this on a Reign 29?
Yeah, i cant say it makes a huge difference. Although im 284lbs and running it at 300 with 4 bands and 2 spacers.
Good or Bad with nomad v4?
Just fitted one to mine, so guess I'll find out!
Nicholas Stanfield any update?
so this isn't a good option for an Intense Carbine because it's progressive?
Lol. Definitely not for my bike then. It’s one of the most progressive bikes. Thanks for the infos. I will say I don’t like tuning things myself though (probably because I’m complete rubbish at it)
So one can assume this would be a good upgrade for a frame designed to run either an air or a coil shock? Such as a Megatower?
I'm starting to wonder, does make it feel plusher. If you put more spacers in does it get harder to bottom out the shock? And why is it better with more negative air conidering this upgrading to this if i think it is as good as it says to be.
They always ship with air shocks. maybe I'll try a coil shock some day, but it's not on my current to-do list.
