Air pressure fluctuations due to temperature. As far as I can research from a warm 30c day to a 0c day you could see a 10% change in pressure. I’m sure there are lots of statistics on this but living in Canada where I’ve ridden 40c and -5 c all I can say is that the pressure difference is not enough to have a pedal hit the ground vs perfect sag. Would agree with the damping changing more at lower temps and have felt that myself but that is in -5. Also about 2 corners into the trail the suspension is moving at such a rate that it heats back up to a level that you would not noticed the difference. Being from Aus originally I don’t feel the temps there change enough to really make it an issue.
Did you go back to one token because you were bottoming out, or was it just a better feel from the spring? I've haven't ridden it yet but I just pulled my last token out. I'm heavier and on a more progressive bike however, but other than not getting full travel I had no issues with 1 token or even 2. Agree the shock is sensational!
@01:32 - I totally agree with this! I'm in New Mexico/Colorado and I run the X2 on my SB160. We had some snow and cold weather and it took about 2 weeks for the lower dryer trails to be rideable. So the bike sat, changed nothing on the tune, same pressure. Began a ride after snow melted and I said, "man this bike feels like a pig today. What is going on?" Went on the climbs and it felt like it weighed 50 pounds. I checked air pressure and added about 15psi more to adjust for the cold air as I forgot about this and it was my first cold air ride at 40 degrees. Maybe most people don't realize this but those who know suspension can feel the difference. It messes with my head and I can't enjoy the ride I keep trying to think of adding more air or more compression. So, I get it and I keep saying I'm getting a coil but end up not because I have no clue on what spring to get. I hate to purchase all kinds of them to find the right one.
That is true about the coil. Excellent once you’ve found your preferred spring rate and preload position, but you’ll likely go back and forth a bit with different springs and fine tuning with preload to find the sweet spot
do you endeavor to use specific amount of stroke while pumping on parking lot? I feel like with proper SAG Im still able to push shock to bottom out bumper easily.
what do you think of this compared to the super deluxe? I am thinking about getting one for a 2nd shock for my remedy while the super deluxe is getting serviced. the super deluxe/lyrik combo has been good to me this season been riding more enduro tracks.
I forgot to ask, you ever ride the Fox X2? If so, how does this compare, the Vivid? Fox is recalling all of their 2020-2023 X2's for brand new 2024 X2's (all new internals), I just need to send mine in.
Yeah I’ve spent a fair bit of time on X2s the 2020-23 shocks were all failing non stop. Under hard riding on certain frames they’d be done in a week, some are lasting a full service cycle. But the new 24 seems to have addressed all the reliability issues. Apart from that the performance of an x2 when set up right is as good as it gets on an air shock. I’d say the new vivid is every bit as good as the X2 in performance, with an easier setup process. But less fine tuning compression range than the X2
The nukeproof spring I bought came with the spacer but was not necessary on the shock, but the spacer was necessary using the mrp progressive spring so it came in handy in the end
Air is 78% nitrogen. Very little gains to be made. Get a hard tail instead and pick better lines. Your knees are nearly 90% of the suspension travel on a FS bike anyway.
It would be killer on that bike aswell. This shock will improve almost any bike given the right setup. Certainly an improvement on the slashes thrushaft shock
I’m 77 ish on the bike. Static sag is a hard one to get accurate on that shock because it equalises at around 30% so it always drops you in from 30-33%ish. Great for performance equalising at sag. To compare the riding sag to the equivalent seated coil sag I’d say 32%. But reads 34 35 because of the eq hole
Thanks for that and putting a video up about the Vivid air as there’s not a lot out there on it ! I might try dropping 20-30 or so psi and see how it behaves as long as the sag doesn’t change to dramatically but it jumps great at the moment just the rougher stuff rock garden type thing it could do with being a bit more compliant apart from that it’s a great shock especially with HBO dialed in .
Theoretically it should be pretty simple to figure out how much your pressure changes with temperature. Ik air isn't an ideal gas, but you could still probably use the ideal gas law PV=nRT to figure it out. Doing that calculation with your shock could tell you pretty close to the exact amount of psi you need to add/remove for a given change in temperature
@@dezzydiamond7121 Yep!, I have fallen in love with my hard tail again. FS bike has been stuck in garage with a blown shock for past 8 weeks. I've had the bits to fix it for 6 weeks.
@@dezzydiamond7121 Some people enjoy getting into the technical weeds of stuff. It's like making coffee, you can get a drinkable cup pretty easily but if your hobby is really sinking your teeth into it you can.
Clunking at full extension, like when the shock or fork extends it hits a hard stop rather than a more controlled transition from extending to fully extended
What kind of trails do you ride? RockShox app recommends me 212 PSI to get 28% sag on this shock, and it's right on the money(with all dials OPEN). I'm confused how you're running 162 PSI, I read below that you're around 77 KG which is exactly what I weigh with all of my gear on. I went for my first ride the other day and had some good size drops to flat and completely bottomed the thing at 210 PSI with 3 tokens in it. If I went down to 162 I think I'd have way too much sag and nowhere near enough pressure to keep it from bottoming. How can you ride it with such low PSI? My Current settings: 212 PSI - 1 Token - 28% SAG HSC - OPEN LSC - Middle Rebound - 9 from Closed HBO + 1 This is my local hill, lots of rocks! ruclips.net/video/EHG_Uh78fVE/видео.html
What bike are you on? The different designs will require different levels of support from the shock to compliment the frame. I’m also at around 33-35% at those numbers

I agree with pressure I always recheck them at lunch when I am at park
True words of wisdom! Sounds like you should service that lockout switch.
Good as gold once I flicked it back and forth. Pretty killer shock

Interesting listen. Ive just got a 23 super deluxe ultimate and absolutely loving that shock at the minute. I think its the same damper as these two??
Yes I believe so
hey mate! who do you go to for the tune on the bomber thx

What coil and adapter you using on your ‘23 SDU?
The nukeproof spring I bought came with the spacer but was not necessary on the shock, but the spacer was necessary using the mrp progressive spring so it came in handy in the end
Perfect thank you! How’s the MRP spring fit?
@@owenswarthout686 yeah it fits fine, but needs the spacer or its too short to get contact on the upper retaining ring
Age old motorsport problem, fill it with nitrogen instead of air. Reacts less to temperature changes.
Yeah I’ve considered a nitrogen setup, but I haven’t made it happen yet
Air is 78% nitrogen. Very little gains to be made.
Get a hard tail instead and pick better lines.

would be interesting what you think about the new vivid on your slash compared to the other shocks you rode it with ?!
It would be killer on that bike aswell. This shock will improve almost any bike given the right setup. Certainly an improvement on the slashes thrushaft shock
