Öhlins RXF 34 ForkSpecialized has had a tight relationship with Öhlins for a few years now, a connection that began with them having exclusive access to Öhlins' TTX rear shock for their Demo DH bike back in 2014. We've since seen almost all of Öhlins' new mountain bike suspension first make an appearance on a Specialized, including their DH fork cartridges, lighter-duty coil-sprung shocks, and even the Swedish company's air-sprung shock. And now Specialized is partnering with Öhlins for their new mid-travel RXF 34 fork that will be available in 120, 140, and 160mm travel options for 29'' wheels. No word on a 27.5'' fork, but we expect it to be offered at some point in the future.
Pricing is in the same ballpark as the best from Fox, RockShox, and DVO, with an MSRP on the RXF 34 of $1,150 USD.RXF 34 Details• Intended use: trail / AM / enduro

www.specialized.com Damper and Spring: The RXF 34 features Öhlins' twin-tube damper design that they claim provides parallel and separated oil flow that controls pressure levels while ensuring initial smoothness and enabling the fork to stay high in its travel. External adjustments include high-speed compression and low-speed compression at the top of the left leg, and low-speed rebound at the opposite end. It sounds like the fork offers a clever air-spring design that employs three different air chambers: two positive and one negative. The company says that this allows for ''the shape of the spring force to be adjusted by the rider,'' which sounds a lot like it lets the rider separate initial sensitivity from end-stroke progression.
There will be three travel options - 120, 140, and 160mm - although there is no official word on if riders will be able to adjust one fork to all three settings. That said, it's likely that Öhlins will be manufacturing a single chassis, meaning that travel will probably be tuneable in some manner, albeit not externally. Don't quote us, though.
Fork Chassis: The chassis sports 34mm stanchions, but Öhlins claims that the RXF's forged ''unicrown'' steerer tube and crown assembly makes it ''more rigid than other brands' 35mm forks, and it's comparable with a 36mm fork.'' This is because the RXF's crown and steerer tube are created from a single piece of aluminum (much like X-Fusion uses) rather than being two separate pieces that are then pressed together.
There is no 20mm thru-axle option, and the RXF's 15mm axle threads in with a hex key and depends on a more traditional, single pinch-bolt on the right fork leg. No quick-release thru-axle system on the RXF.
The new Öhlins suspension will be available through Specialized dealers, who are going to have the RXF fork (and shocks, springs, and cartridges) in the near future, as well through the Öhlins USA website that will be shipping and servicing suspension out of their headquarters in North Carolina.
We'll have our hands on the new Öhlins RXF fork shortly, and you'll be able to read about what's inside and, more importantly, how it performs and compares to the competition.

Are you one of us? Can you... feeeeeel meeeeeee?

Why not make it a 35 that is stiffer than a 36 then? Weight disadvantage negligible.
There is the obvious issues of messing with the geometry. ......but reckon it should work!
I asked why? "nothing better available"..
This was when Yamaha owned a majority stake in the company, and Ken Ohlins(founder) bought back a 95% stake in 2007, which has lead to more involvement in the auto industry, and as we're all seeing now, the MTB industry as well.
Ohlins is the only company I would buy product from sight-unseen/tested.
Heck, plenty of people get on great with the Revelation, & it's a "wimpy" 32mm. I've got a DT Swiss that doesn't ever seem to bushing bind, while a Fox F29 I have does exactly that.
But for the average user, the message should still be: stiff forks are are stiff, flexy forks are flexy, & you can't tell which is which just by stanchion diameter. & if you're under 175 lbs, it may not matter for you anyway.
With an USD fork you're specifically you're talking about the lack of torsional stiffness and mucho independent stanchion movement that makes it track well. This is also what makes the same fork feel vague on rough, high speed tracks and harsh berms.
I know you know this but it needed clarification.
Most riders only see them on Red Bull TV.
How much bushing overlap is happening inside the fork? That will have a large effect on chassis stiffness......
IF IT WAS SIMPLY ABOUT PERFORMANCE, THEN 26" WOULD STILL BE IN MAINSTREAM PRODUCTION AND WE COULD CHOOSE FOR OURSELVES.
Could be a very good deal
hUH?
#1 ti coil spring
#2 open oil bath
#3 20mm axle
(27.5").
Also aren't they working a double crown fork at the moment?

Lets start with the 29er thing.... No company is that dumb to offer only a 29er fork when entering the fork market. The one-piece cast lower legs will have to change for the different wheel sizes. These are highly tooled components. Tooling is expensive capital investment. I bet one of two things is happening here.
1. They tooled up for 29er first to mesh well with Specialized bike offering and to "test the waters" to see how their product is received in the market. If things look positive, then the CEO will sign the check for additional tooling to cover the other popular wheel size (27.5). This gives them time to sort out any issues before cranking out the 27.5 lineup.
2. Or maybe the 27.5 is lagging due to issues with tooling manufacturer, maybe a design issue is driving redevelopment of other components for packaging, who knows...But perhaps 27.5 is on the way already and just lagging.
So what about 26"? Well, we all know those are popular in the DH world. So if Ohlins makes a fork 26" it will probably be a dual crown fork. We will have to wait and see if they decide to go that route.
Now lets look at the 34mm stanctions. Spindly in comparison to the beefy/stout looking Fox 36 lineup.
Ohlins claims that they are stiffer (or comparably stiff) because of their one-piece crown/steer tube design.
So let me get this straight.... They claim more stiffness at the crown/steer tube joint somehow makes up for the small stanctions....? Explain please? Does that mean that the competition flexes at that crown/steer joint to a point that it negates the advantage of the thicker stanctions?
Now, the all important price point. They have positioned them selves at the top of the market, in direct competition with Fox (and to a lesser degree RS). A new brand (to this market anyway) and relatively unknown to most bikers to slot themselves at the top of the market is risky. Sure they want to be the "premium" offering, but they are standing square in the same spot as Fox, who really is dominant and continues to grow. With Fox moving some production overseas, they are going to see reduced costs and spec'd more by bike OEM's for factory builds. Ohlins, needs to prove they are premium in some way, not just by price. It is a long battle. They have to win shoot-out after shoot-out with clear dominance over Fox (who is no slouch) and every other brand. This takes time. Basically you have to earn your spot at the top, and Fox has over many many years.
Just my 2 cents....
Good luck to Ohlins!
(p.s. I am not involved with the bike industry, just a guy who rides and reads)
@oregonryder I'd assume Ohlins has proved a bit of their premiumness in other markets (moto etc) and a bit with the rear shocks already.
IF IT WAS SIMPLY ABOUT PERFORMANCE, THEN 26" WOULD STILL BE IN MAINSTREAM PRODUCTION AND WE COULD CHOOSE FOR OURSELVES.

If it has wheels and goes fast, it likely has Öhlins on it. Take a look here: www.ohlins.com/about/hall-of-fame
