Myself:- I have a litre bottle of the current shimano fluid and a small bottle of royal blood, they're notably different viscousities when you compare them, but neither are as thin as DOT. If the new shimano fluid is even close to DOT, they're probably on to a winner.

Sounds like a lot of work to replace DOT then try to get close to DOT instead of just using DOT...

This little tire plug setup looks pretty damn rad!!  Not bad for a kid that has only been out of high school for a year!! https://www.instagram.com/reel/C-k7COvRC2z/?igsh=NHRrM2p4bnd2Y3Jn

Been thinking about a 3D printed version of this for the past few weeks now and the solution with cuttable gromets is really, really good and adjustable. Probably a lot better than using an O-ring Smile

I have had mine for a month or two now and from what I heard he tried a few versions and his setup with the custom cut grommets is pretty impressive!  Fits right into my Message and isn’t going anywhere unless I pull it out to use it.  He done good!!😂. And help the guy out!!  Don’t steal IP please. 🙏

Many companies are trying to get away from DOT and other chemicals due to EU regulations. I believe that is one of the factors in SRAM switching to mineral oil.

With the new x2 and EXT shocks changing shape, is it time to start discussing shocks becoming crab too? Vertical reservoirs are on the way out now, with Ohlins being early adopters of horizontal reservoirs.

I had assumed that it was easier to package the twin tube base valve / adjusters that way, but with the DVO shocks and new Fox Float/DH X2s going sideways I'd guess it's just a packaging / frame fitment decision.

Apologies if I missed this discussion, but I’m very curious to know what smarter people than me think about the Rallon’s low anti-squat. As someone who has been planning to get a new enduro bike and DH bike over the next 12 months, I find this bike very appealing. However, I love big backcountry days on the enduro bike, and I’m worried this bike won’t be particularly good for that without an electronic shock to compensate for the anti-squat. Anyone else having similar thoughts?

On a related note, good on Orbea for not glossing over this compromise and formally addressing it.

I believe the pinkbike reviewer said he was pleasantly surprised by how well it pedalled despite the numbers, and that it didn't necessarily need the electronics on the shock to work. I'm sure a regular pedal/climb switch would deal with it rather well.

Ya, around 2021 super high antisquat was all the rage, esp. with things like O-Chain, now it looks like low antisquat is back in style.

Sounds like a great trend. Pedal circles and don’t mash your pedals, use a lock out, or go with Neo. No need to sacrifice suspension performance on a long travel bike.

We had a request for clarification pop up on the post, here's the answer from Öhlins with some more details around the changes being discussed in the press release above: 

The new surface treatment has reduced friction, and the compression damping base tune has been backed off a little. As a result, the fork feels softer. To compensate, the spring curve has been made a little bit more progressive, through the addition of spacers in the ramp-up chamber (yes, it's still the same, 3-chambner design). The "booster" they mention is some kind of insert or spacer that reduces the volume in the lower leg on the damper side, meaning they are using the lowers as part of the total spring system as well. Additionally, in the RXF38 m.3 they have removed both spacers from the negative spring (they are both included in the box), while the DH38 m.2 still has one spacer installed from factory in the negative spring.

The "booster" looks like what you would see in a moto spring perch. Which typically controls the low bath fluid flow. I would be super interested in how it works on an MTB fork. I am surprised that something like this hasnt come sooner but there isn't much volume to play with on here. These might be really nice with a coil fork and messing with oil volume heights.

IIRC Ohlins used a spacer in one leg to increase progression of their coil RXF36 m.2, I'm not sure if the current models do, but usage of a spacer for that purposes dates back a while with them.

thanks for the quick turnaround Smile


Any idea if these upgrades can be done with a damper service? I assume the compression tune and negative spacer would be easy.

Kudos to Ohlins for simple no nonsense evolution of an already great suspension based on rider feedback. Tried and true TTX18 damper that just works and is easy to service. This is refreshing in a sea of flashy marketing crap we have been bombarded with all season. We don't need your butter cups and 17% stiffer generatively designed arches.

So they made it rely more on the air spring and less on the damper? 

Less of what Ohlins has been and more like RS/Fox? 

Thankfully nothing a tune won't fix. I love my RFX36 and TTX22M.2 coil.

It’s all backwards compatible, so I assume it could be done during a full service.

Correct. I believe it's in the spring side, though. I'll have the lowers off mine this week and can confirm, if anyone cares.

From the other site.. could this be the new hope calliper? Looks to have a different bleed port.

No need to go by feel (though you are correct).  As per their respective SDS's.

low anti squad usually means low rearward axle path (without any idlers involved)

which i dislike.

but antisquat overall i a bit of a weird metric because it's calculation relies on the exact gearing and position of the center of gravity.
so it is always a bit of a gamble if the antisquat really works for you as intended

The shock is "live" on the US Ext website: https://extusa.bike/products/ext-vecta

$325 cheaper than the Storia V4. Euro pricing on the V4 is similar, so it will probably be around the same €750-775 in euros as well.

Good eye - IIRC that bleed port looks to be the same as on the lever someone posted here a few weeks ago. So we'll probably see a new bleed kit from them with two syringes for push/pull bleeds.

It's also the same as the one on their gravel caliper
