If you only use a spring cartridge with a smaller diameter, the spring-side ramp-up from the lowers will also be reduced as the volume is increased with the stanchion being opened up.

Apparently connecting the bleedports of the Zeb reduces the ramp-up. If true, I'd say it's because the damper side is experiencing exactly this - a much larger lowers volume overall with less ramp-up. Bleeding the spring-side air to the damper side will offset some of that issue and bring it to somewhere in the middle of it all ramp-up-wise.

How would you connect the bleed ports though?

You guys are having trouble bottoming out a Zebb? Weird…
 

Oh wait! I just remembered: I’m a 100 kg American fat body. Sick

I'm pretty sure my 170 Zeb has only hit 170 once and I had the sore elbows to prove it for a week after that one. Gotta get on those push ups....

What would happen if you just put pneumatic filters on the Release Valves of the ZEB so the presure in the lowers is the same as on the outside.

95kg an no issues using full travel on my 170 & 180mm zeb on Big hits if i ask it to.
a friend had issues getting full travel on his so he had it serviced/bushings done and its been excellent ever since.

Like I mentioned in the other thread, connecting the two lowers can cause the oil to flow from one side to the other, depending on the fork orientation. That would of course cause oil starvation in the lowers, which is not a good thing. The same miiiiight happen with filters and I'd still be vary of dirt being pulled into the lowers.

More importantly, a somewhat high enough level of air permeability to cover the pressure ramp up and actually offgas the excessive air in the lowers might not be reachable if you have the filtration capabilities to prevent dirt ingress.

I think it would make sense to solve this issue in a different manner to be honest.

Looks like it's not just an air version of the coil shock given the new damper. Does the mean a coil vivid is also coming?

I am a total layman when it comes to suspension, but it sounds to me like the damper in the new Vivid was designed to combat some of the negatives of an air shock i.e stiction, being supple in the first part of the stroke.  So it doesn't seem like tech isn't necessarily needed in a coil shock.

Hoof it got pulled right after I read it: to sum up what I remember: big difference with the SD is an early stroke oil bypass, after the first 30% of travel the main piston engages, plus the HBO seen on the SD. Retail price between $550 and $580 depending on stroke. Did I miss anything? 

BTW, I guess that press release article means it's already in the hands of journalists. Must be close to a release. I don't think they will introduce a new Vivid coil, or at least it's not being tested at WCs.

It was mentioned in that article that this vivid is going to be air only 👍

Service intervals increased from 50h to 100h.

Its just basically a current coil super deluxe with an air can and some bullshit marketing.

I hope the new Vivid will be easier to change the volume tokens on than the old one (required special tools).  When I owned one, I knew I needed to add tokens, but never got around to doing it because of the hassle before I sold it.  In the photos,

What's the difference between the Vivid Ultimate & the Vivid Ultimate DH version? edited: looks like the DH version looses the climb switch.

 

I ordered an EXT Aria but frankly would rather have this shock on my Relay.

Normally the Resi in relation to lock out or climb, Similar to fox offerings is my guess?

It will be a alloy Horst Link bike with vertikal shock mount. You already can see the blurred bike on the Youtube Channel from Mark Diekmann. On the top tube stays the name „Scrub“.

Spotted the reverse-arch Fox XC fork again in the Lifetime Grand Prix social media coverage of the Leadville 100. Resolution on the 2nd screenshot here is not great, but does it look to anyone else like the trail is visible through part of the arch? Maybe skeletonized to save even more weight? Might just be an optical illusion or weird reflection.

Yes indeed, that's how it looked to me too. It looks as if the arch is kind of folding backward, like some sort of generative design.
