Ohlins have
just released an updated version of their DH38 double crown fork but it looks like that's not the only 38mm stanchion fork they've had in the works as we've just spotted this single crown RXF 38 specced on a new limited edition eMTB.
The Thok TK01 LTD bike is limited to 35 units, painted and assembled in Italy and customized with the name of the owner. It's supposed to show off the very best of the brand and is kitted out with a very high end spec - the price is listed as €0 so we're guessing it's one of those 'if you have to ask, you can't afford it' type situations. The thing that stood out to us though, was the new fork in the spec list, one we hadn't seen before.
The RXF 38 looks very similar in design to the RXF 36, and it likely uses the same TTX18 twin-piston design damper as the RXF 36 - that's almost confirmed by seeing it also has the same ramp-up valve on the right fork leg.
On this bike, the fork houses a 29" wheel, has 180mm of travel and, interestingly, a 1.8" steerer tube. This was a standard we
first spotted at Eurobike last year as SR Suntour had it on their stand fitted to a Bulls ebike. Rather than the common 1.5" tapered steerer that everyone uses, this fork had a 1.8" steerer that tapered down to 1.125" at the top where your stem clamps, and it looks like this new Ohlins fork is the same.
At the time, we spoke to RockShox and Suntour and they both said that the fork would be OE only for the time being, and while there are probably some improvements in rigidity, the 'Supertaper' standard was mainly aesthetic, allowing the bottom of the head tube to better match bulbous downtubes created by integrating batteries into ebikes.
Ohlins said: "This will be an OEM product only via a number of top MTB brands and will be launched August this year via the release of new 2020 bike models. There are plans to make an aftermarket version in the Q1 of 2021. Also - The fork is not 1.8 tapered but the standard 1.5."
And 114.999998mm axle length.
WakI: Should have gone 2” directly
Ohlins: We planned to roll that out in 2022 to make the 1.8" obsolete. #newstandardevery2years #bicycles.
LOL
But how do I fit the new fork onto my 1996 Klein Mantra? Is the fork compatible with my softride suspension stem? LOL

Give me a dual crown 1 1/8" any day over a single crown with a bigger steerer.
Maybe they think some Flex is needed in the Fork to get a good ride feeling. But if the Stanchion and Lowers flex to each other, they cant move freely into each other, which ends in poor suspension performance. Since they want good suspension performance the only part for flex is the head tube.
But i still think they should change something that the Forks dont allways start to be noisy after only a few rides.
So there are no 26in, 27.5in nor 29in wheels.
I believe 700c means 700mm overall diameter of wheel with rim and tire of a certain size (probably ~2in) and the c is for a certain range of inner rim width.
Legacy measurements run deep, I’ll lay to that.
What I'm getting at, is there is constant updated, changes, and new standards. People continue to get bent out of shape (Which is futile) and eventually we all just accept it, just to get bent out of shape on the next one. I'm sure 1.5-1-1/8 steer tubes aren't going anywhere, just as strait 1-1/8 aren't either, but nobody can deny that this is a logical fix to remedy a weak point in the structure of a single crown fork.
Not only would it allow the fork to become undeniably lighter and stiffer, especially compared to a dual crown fork, it would open up options to further refine the CSU. People are so quick to point out the flaws in products (especially suspention) that they fail to step back and really see how incredible suspention really is. In fact, maybe just over 5 years ago, you could almost consider suspention to be archaic.
Take into consideration that we are just now scratching the surface of what's possible.
We had to endure elastomers, cartridges, and silly shit that did not work and a real design engineer would laugh at.
I know sometimes progress is slow, but there is no excuse for a shitty design that has to be modded out of the box to work properly, If a tiny company can figure out what is wrong with a fork and make a part to correct it, what does that say for the company. And I am not talking race level performance just plain work.
The complaints about new standards for e bikes are understandable because it is an inconvenience. But the fact of the matter is that e bikes need new standards because they are heavier and put more stress on some parts. And many of the e bike options are great for big guys or people who want to make their bike stronger.
Secondly, you need to think about financial return. Every manufacturer (especially major players) have shareholders that expect a return on their investment. Corporate company's divy out budgets for each department for. One of those departments are design and engineering. One flaw could be the result of lack of budget.
Third, one major thing to consider is company perspective. Just as people have pointed out their dislike for the new fox 38 due to the csu design with the elliptical steer tube; That was ultimately fox's answer to an issue they had experienced without introducing a new standard. While maybe not without flaws, you can see the company is moving forward in identifying development challenges, and applying new techniques to remedy such challenges.
As we proceed through the eras of product evolvment, we will also see more and more challenges arise. As each challenge comes our way, there will be remedys to mitigate such challenges.
While this is no excuse for poor craftsmanship, or faulty products; It does however shine light on why and how flaws come to light. Especially when your manufacturing products in high volume in a semi controlled environment.
Once again, there needs to be a target price for the end consumer, and overhead such as development costs, manufacturing, marketing, logistics, profit, and retail costs all have to fall within the MSRP.
I'm sure if you had unlimited funding, you could eliminate every and all issues, but nobody does and nobody will.

Cos if not, then there's little point
Like it will make a difference for me being 85kg kitted now and then riding a bike 5kg heavier.
Or are they trying to help the 300lbs+ crowds into cycling? Get them off their electric personal mobility carts???
Is not disappointed. ????????????????
