If you've really got 5mm to the o-ring, you've got something weird going on.  There should be roughly a 1.5-2 o-ring's width between the end of the stanchion and the o-ring.  Like, the equivalent of 5% sag on the markings.IMG 6656.JPG?VersionId=Ww3ESb2M4LJ9eux

One guess is that maybe someone installed travel reducers in your shock after it was manufactured.  See the service manual page 51:  https://www.sram.com/globalassets/document-hierarchy/service-manuals/rockshox/rear-suspension/2024-vivid-service-manual.pdf  There are 2 possible travel reducer locations, the air can one is pretty obvious and easy to check and remove if needed.  It looks like you can check if the eyelet travel reducer is like 1 more step to check if it's present, but basically requires a full rebuild to remove.

Good point on the travel reducer, I'll give that a check. I pulled out the factory installed volume spacer but didn't look for a travel reducer.

This is the max the o-ring can hit:

20250331 152311

Hamncheez, the bike is an Ari La Sal that has the crab-link suspension. Its possible the c37 tune plus the progressive suspension is causing this but not very likely from my thinking, especially if adding more compression doesn't impact how much travel is used. 

If I can't see anything glaringly obvious when I service it then I'll check with RS, especially since others don't appear to be experiencing this. 

Thanks!

Some shocks may not go all the way to the end. Have you measured how far from the dust wiper to the o-ring is?

Measured the o-ring at around 60mm travel with a little over 5mm left at the end. This shock was for a SB160, but aside from the unneeded hardware and slightly different compression tune nothing else seemed unique. Sold as 230x65, unless a travel reducer was installed without mention - which is possible

And with that, last post on this until I pull it apart. 

Apologies for the hijack.

They have a ~5mm tall rubber bumper which will be very hard to compress the whole way, especially by hand

What are we even doing here

Need a new thread "Damper products that ARE suspension"

Likely.

 

(Properly) changing a Vivid's travel is no trivial task, it's doubtful unless it's been through a shop.

 

Anyway, go to MTBR for susp tech support.

If you want actual help I would personally recommend a suspension service centre

I heard a rumor that this new ebike from Specialized can toggle between class 1 and class 3. If true, this blatant disregard for land and recreation managers from one of the United States' biggest sellers is pretty sh*tty.

And yet entirely in keeping with the overall industry ethos.  My biggest initial reservation on ebikes was around their potential implications for access.  Rules vary a lot and in their quest for sales I can't recall any company providing any sort of guidance on potential "ethics".   I recall one manufacturer taking a fleet of Ebikes on a dealer demo past a "no motors" sign in Whistler.....

The implication that users will self police themselves is naive at best and disingenuous at worst...

Any rumors on a new Propain Tyee? Surely it’s going to get frame storage like the Spindrift is and they’re blowing them out right now.

The tyre is new, it’s got to pay for the molds first, the next one up is the Hugene to be renewed

Love the paint colors, and the frame looks very svelte even with their in-frame storage. Hoping the geo is better in the larger sizes, especially the stack to reach ratio 🤞🏽

Cool bike, but Pivot and Santa Cruz are shooting themselves in the foot by only producing Enduro and DH bikes in Carbon Fiber. Most people don't want to baby a long travel rig everywhere they go, they just want to ride it. Go ahead and down vote this post, I don't care.

I used to be of the same mindset, having just broken an aluminium enduro bike, I'm not so sure anymore.

What do you mean baby a long travel rig? Have you seen what material gravity race bikes have been made from for the last........10 years? I've seen more catastrophically broken alloy bikes in that time, and Pivot/Santa Cruz customers just plain don't want Aluminium anyway

Geo looks pretty solid to me, I like the XL with the 445 stays (low bb mx wheels)

Yep, I got sick of cracking alloy bikes so Been on Carbon only unless the bike i want to test only comes in alloy.
Think I've cracked pretty much every alloy bike i've owned except for the new Marin alpine & a merida

Want to be a carbon hater as much as the next guy, but only frame I've broken was full carbon except the chainstays, which broke. (strength where it matters amirite?) Happened on hard turning/breaking, not a big drop or harsh bottom out.

I do think Atherton is onto something truly innovative with the S range. They're the only bikes that can tempt me at full price at the present moment.

100% that’s a big improvement for XL too!

Kate Courtney is in Brazil already, posted a ride 31/3 with a pic of what I guess is her regular BC40 with red SIDs. 
Yesterday 1/4 posted a ride called new bike day, she’s Called the bike BC40 sparkle, can only see that it’s got purple-ish forks; and has otherwise kept the bike hidden. 
Possibly new, possibly just a custom paint job, possibly new rockshox stuff about to be revealed?

Nothing wrong with a carbon front triangle! In my opinion it's only the rear end that's susceptible to dings and rock impacts that ideally should be alloy.

When printing 7075 stops being exclusively for NASA applications, that's when some truly insane bikes will start to hit the market. I'm hoping to start prototyping my own alloy lugged rig from September and I'll be updating this forum on how it all goes!
