Okay, let's pretend to be an open-minded bunch for this one, just for a few minutes. The Scurra 2 is the ''
most unique enduro bike,'' according to the company itself and, with a wild linkage fork up front that's controlled by a Magura shock and paired with a dual-link rear-end, it's hard to argue with them on that point. The fork is home to a 29'' front wheel (the rear wheels is 27.5'') and it delivers 170mm of travel, while the back of the bike has 200mm on tap. No, this is not your average enduro machine
First things first: what the hell is going on with that fork?
Suspension forks are pretty damn good these days, and I wouldn't say that anything from Fox, RockShox, and the rest of the gang are holding us back, but Scurra believes that depending on bushings is a silly way to going about things when you need your suspension to be as active as possible. Stanchion tubes sliding in and out of bushings feels smooth to me, and fork arches and axles seem to do a decent job of creating a stiff chassis, but this small Austrian brand says that they can do better with their 'Trelever' linkage fork.
They cite the evolution of motorbike rear suspension as a good argument for investigating a linkage fork: ''... rear suspension also designed with telescopic forks - plungers (just like front suspension nowadays), but as technology progressed, forks were replaced with more effective ideas - the first: simple swingarm. At the end of the 1950s, the rear wheel swingarm, known since the 1910s, replaced that construction of the straight-travel spring suspension. And finally, the last development by mountain bikes - 2 systems based on parallelogram technology: the 4-link suspension and virtual pivot point.''
Taking that thinking, Scurra designed their Trelever linkage fork. The idea is that the sealed bearings offer way less friction than a bushing-based design of a traditional fork, and they can also control anti-dive and the front axle path to make it to their liking. The fork activates a Magura shock that's located directly in front of the rear shock, a layout that Scurra says keeps the bike's weight centered.
The dual-link rear-end delivers 200mm of travel, also controlled by a Magura shock, and the geometry can be adjusted via a cam system without having to loosen any bolts: simply turn the cam with a hex key to change its head angle, bottom bracket height, and a few other numbers.
The aluminum frame kit is made to order in medium, large, and extra-large sizes, and the retail price is around €5,000. That's a big chunk of money, no doubt, and it will get you the frame, Trelever linkage fork, and two shocks.
I'm really curious as to how well it rides.
(And I'm always amazed at how many pinkbikers care more about looks than performance.)

I read im another article that the whole bike weighs 14-15 kg and the fork and front damper weigh about 2,5 kg. That isn't much and compared to a standard fork. you have the advantage that you can use carbon on this construction so it has the potential to become as light as standard fork maybe
This is never going to replace a fork completely so it doesn't threaten your comfort zone. It just gives you another option and something interesting to test and make a decision on if you care or just ignore if you are happy with a fork.
2- Is anyone forcing you to spend the time and effort on it? If the answer is no then why do you give a shit?
You cant expect goons that whinge about wheel size like the above to think any form of development that doesnt comply with their pre-concieved ideas of how a bike should look is a good idea.
"Kill new ideas with fire" - Im so glad the whole world isnt made up of people like, we would still be in caves.
My opinion is that it's ugly and I stand by that. I have no idea how it would work/ride and to be honest don't really care. I'm happy with the bike I have.
In other words motorcycles have been experimenting with this for literally decades now. It's never caught on with consumers, but the advantages are supposed to be the same as what they said in this article - controlled dive, separation of braking and steering forces.
Never had the good luck to try one myself. They tend to be exotics or just regular BMWs
Girvin.
Amp.
Lawwill.
Whyte.
Mountain bikers have been experimenting with linkage forks for decades, too. I had an Amp. It worked well, but the bearings would wear out too quickly, and were difficult to replace.
For your info, the same comments were directed towards the telescopic forks, once upon a time when they first appear (ah. Along with all those “expert” opinions on how much energy you are going to loose by the fork’s action!!!)
So,
Keep your negativity to yourself.
yeah I had the carbon one...sweet. It was "rebound" replacement to a Lawill Leader on a build. The air shock failed on the Lawill first air up.lol
@Tocomotion - I was just enterained by the idea of putting swing arm in the front and fork in the back... front wheel drive has already been done too
Actually, they chose 26 because the 700cc wheels of the day and the technology available couldn't stand up to the beating.
@Darknut - honestly? That argument by such design? And you take that joke out of context like that? You can pull out "how about you ride a bike with cantilever brakes" right now. I heard that even by the occasion of Boost.
Well,
What’s keeping you!? (industrial design pseudo perspective, rough-sketch style or something more realistic?)
Yep.
Someone has to inform that kid that humanity has suffered the “dark ages” and their various reincarnations…
Killing ideas just to look cool. How sad…
Or: Let's attack Roman Empire! Yea we get straight to Rome! - How will we find it? - all roads lead to R... - shut the fk up, that's how we always did it you fashion nazi! We'll get Elephants, through Alps!
Hey kiddo.
Don’t lose it now… YOU ARE THE HATER! Every time PB covers something that’s out of the mainstream aesthetics, you post the same message:
Kill it with fire!
Just like the dark ages (the medieval times, as I mentioned before). You are going to “kill” all that does not comply with your norm. With that I mean that YOUR NAZI FASHION ideas seem to “energize” every time you see something interesting, a new design or a new idea.
And watch you manners kiddo. When you write “kill it with fire” you DO EVOKE bad memories. I assume that you know by now who was burning people at the stake (yep, the church), or books (yep, the Nazis). So, now that you know (finally) I expect from you, more… educated posts.
As for your manners, go and talk like that to your Mother… kiddo.
History. Just read some and you will see that "we" are repeating the same shit (burn it with fire)... even in the small scale of bike design...
YES!
For the love of "him", so many people got burned at the stake...
It takes at least 2 to have a discussion....
C"mon !!
If that really was your first thought, you can't afford this bike anyway, stick to a hardtail.
1. Wrong, there are no more than 8 bearings in the fork which is all were talking about, the cost of replacing the bearings in the frame is what it is, you'd have to pay that anyway, you're just trying to make it sound worse by adding it together.
2. Cost, all you've done there is find the highest price you can on the internet to again hike up this cost to make your point and prove how clever you are. Even if you used Enduro Max type bearings (the most expensive), you can get them for almost half what you've quoted, but given the extra friction caused by the seals and careless design of these bearings they may not be the best choice in this application anyway, but of course you'd know that already wouldn't you smarty pants.
3. Labour costs, if you can't replace a bearing, you are retarded, and should be charged double for everything in life because you are a liability to the whole of society, and should give back what you will inadvertently take out by being f*cking stupid, bit like insurance costs, you pay more because you are more likely to f*ck up.
Go ahead and talk some more shit mate i love it.
So that's about $32 rather than $240.
I wouldn't be surprised if this is loads stiffer than a telescopic fork - having just one connection to the frame via the headtube and a load of sliding bushings makes forks very bendy. We just don't know any better because we never ride anything else.
But wait, should this be posted on Pinkbike in the USA?
I can't help it. I'm still upset we were left out of the ebike discussion and the content wasn't posted in the USA.
It's a sad state of affairs here in our country when journalists feel they might offend their audience by reporting the news.
Granted, I didn't notice that tendency in the video, but it would be a good thing to the manufacturer to address directly before they can hope for widespread adoption.
A linkage fork can move the front wheel however the designer chooses. The problem with many has been the *choice* to move the wheel rearward, for exactly the reason you describe.
As the Scurra goes through its travel, the head angle becomes steeper, front-centre becomes shorter, and trail decreases (though mechanical trail does increase). My analysis isn't accurate enough to comment on how these properties compare to a telescoping fork.
Our choice with the Structure was to be more aggressive with the dynamic geometry, making the head angle become slacker, maintaining front-centre length, and substantially increasing trail and mechanical trail through the travel. I can't say in absolute terms that one design is better than the other; naturally, I prefer the Structure (if I didn't, I would've redesigned it!), but I suspect the Scurra will take almost zero adaptation, while the Structure takes a few minutes to get used to, which will appeal to some.
The bottom line is that we commend Scurra for taking a bold step in the effort to improve on the fundamental design of the bicycle and increasing awareness of front linkage designs. The market is certainly big enough for both of us and we wish them well!
...
"Nah..."
I believe Linkage has been figured out and we are pretty much all content with the options that are available. Trying to be "radical" at this point kinda just takes away from being taken seriously.
Change is good and all, but this is not going to be the future of mountain bike suspension. It really makes good use of the saying, 'Just because you can, doesn't mean you should'.
