Are there any rumors about the RockShox lineup?

Apologies if I missed it (I’ve only consumed about 800 of the 846 pages in this forum while I shoulda been working or parenting) but is the 38 imminently due for a release? 

Assuming it’ll have a a staggered announcement like all these others trickling out but haven’t seen much chatter about the 38. Burly single crowns are my jam. 

I vaguely recall some talk of a Fox USD fork a while back but not much else in the forums about a new 38 so wondering whether it’ll get a major overhaul or the same kind of incremental updates as the 36.

 

This information is on one of the 46 pages you haven't read yet. 

In all seriousness, I don't recall seeing any information regarding the 38... but I guess I could of missed it too.

Nothing 38 has been officially rumoured yet... i think it's safe to say it's an inevitable rumour.

After that many years and issues on the same platform, it would have been a good time to rename the Float X2 to Float X3 to try to differentiate it from the unreliable last version 😅

The only hint I've seen is on the mud guard page, it shows the current version is for 2025 and earlier.

I thought I had posted this weeks ago, with what I think is a new 38, it could be the 36, but that bike seems more suited to a 38.

good eyes.  has the cutout arch ala the 34/36 SL.  wonder what's going on with the dongle on the bottom of the drive side lowers?  reminds me of the 40 penis from early days of that fork

All they really need to do is add that glidecore spring to the updated grip x2 38, as they have improved bushing overlap anyway.

Nice sleuthing chriskief - you get 8 1/2 Sherlocks out of 10 for that one. 

Finkill, pic angle makes it look like you stumbled across a proto fork for that 32/29er mullet all the XCers are getting hot and heavy over!

HBO is a nice "safety" feature - you can make a good shock without it so I'm not sure if its a deal breaker but I would definitely prefer HBO than externally adjustable High speed rebound.

Keeps you from breaking frames from repeated bottoming. If I was an OEM I'd be interested in HBO to cut down on warranties, particularly on aluminum frames with lifetime warranty.

Forum rats: "Why didn't they release the 36 wtih 170mm support? These larger stanchions (like the 38) are only to make ebikes look better" 
 

Whats your favorite single crown for,\k of all time, Forum Rat?

Yup but energy and heat aren't the same thing - a small alloy bolt only needs a small amount of energy to raise its temperature while a comparatively large shock needs far more energy to heat it to the same amount. Point a heat gun at a shock bolt for 5 seconds then pick it up - it will probably be too hot to handle, but do that to a shock and it will be barely any warmer than before, even though received the same amount energy (probably not quite because surface area but you get the point). 

I think the reason I mentioned it was with the Scott specifically I have worked on those bikes and found the fit of the bushings at the trunnion mount crazy tight so it was a possibility, unlike normal eyelets. Also heat is slow to be conducted across 2 different parts, so for it to be able to transfer the energy through the threads of the bolt and outside the frame would mean the shock is getting REALLY hot

Do temps of mountain bikes shocks really matter, when you can just tune it for a given temperature range? If you know during a DH run your shock will be in the 40-55C range, just tune it for that range. Its not like thats outside the envelope of what suspension oil can handle. 

Anyways, ignore what I said above, I'm developing a new product thats a Graphene additive to your suspension fuild that makes it 28.99% more tempurature stable, which in real life testing improves your suspension performance by at least 1 place on the poduim, even if you're not racing and just out on a solo ride.

I could believe it, maybe 2027 is 32" 38 Forks. Guess they will start with the 32x32 fork first.

There was the redacted post about the new Enduro fork, but that could be the 39 and not the 38 based on what was confirmed in the post.

Yup! One of the major problems with coil shocks on OE bikes is the majority of them get sold without changing the spring so the chances of excessive bottoming is way higher....anything to help reduce the damage is definitely a good thing

Ohhh yeah good call....I'm pretty sure graphene is the solution for everything! 

 

But yeah you pretty much nailed it - shocks generally stabilise around a fairly small window so really when you do your tuning you are always adjusting for how it feels when its warm anyway. The biggest temperature effects come from the change in pressure in the air spring or reservoir (if it has a large shaft, eg DVO) which can be noticeable in certain situations though

Neko said in the Jensons Fox 36 video that he was running the new 36 at 160mm instead of a 38 at 170mm and just lived with the axle to crown being 7mm shorter.

What if... the usd fork we keep rumourin' about it's actually the first 32" production fork (possibly an XC fork)? IIRC there was a photo some time ago of an Intend usd with a 32" wheel, most likely a modified 29" Samurai XC fork.

I just feel like that would be one of the worst ways to introduce a new step into a companies portfolio and advancement. Making a possibly very advantageous fork and then proceed to gate keep it, behind a very big (literally) new wheel size standard that no one has really asked for. 

Who am I kidding? We are mountain bikers! We are very open minded to new ideas and changes.

After spending some time on it, it’s basically a mandatory feature for me now.

Now that I've had it, I wouldn't want to go back. It's been a luxury to run a 50lb lighter spring while also virtually eliminating bottom outs and end of travel harshness. Went from a DHX at 400lbs to a SDLX at 350 fwiw.

My Vivid has HBO but no matter the settings,  nor how big the huck to flat that almost explode my ankles, the last 5mm is complete unobtainium. 

I wouldn't think its the HBO, but I can hit the same spot at 29% sag and 40% sag plus max to least compression set. HBO also set to max and min too.

A SDU without HBO and a X2 could use all 65mm stroke though, so the only thing I can guess is it's the HBO.
