It's light, compliant, progressive, and it's got that WTF factor that some people like.
I'll confess I think a Girvin fork looks cool. This is a "Road Less Traveled" fork.
This is air-ride for your CX bike.


Lack of a lockout will have some whining that they have to change their riding style to accommodate this strange-looking fork, and it doesn't have 4" of travel like a conventional fork.
This isn't for downhillers, flying squirrels, big droppers and people who break stuff.
It's not cheap.

I've mounted this fork to an ICAN carbon CX frame. I've built the wheels to run with it, 32h WTB i21 LaserDisc, and I'm using a pair of WTB Nano 40C tubeless tires. The intent of this rig is to be a fun, light and comfortable Gravel Grinder, over built to make the rough parts smoother. Coming from mountain bikes rather than road bikes, I like the feel of a suspension fork, I like disc brakes, and I prefer more to less travel.
Unboxed, it's beautiful, and it's light. I should have another just to put on the coffee table.
Installed, it jacked up the nose and BB of the CX frame as you would expect over the rigid carbon fork.
Adjustments- none. Needed spacers to fit the brake caliper (Hayes CX-5, the barrel of the caliper hits before the mounting pads, I used a set of Avid self-leveling adapters top and bottom. Sorted) and it's set up to take a minimum 180 rotor. More brake does not make me sad.
So the ride- it's smooth. Under normal conditions, the axle simply floats behind the fork, similar to air ride, but with zero stiction. Bumps, seams, manhole covers- easily absorbed and attenuated. Feeling it suck in a speed bump just felt cool over the rigid fork. No issues tipping it into corners, it's a bit slacker than it was, so not as razor sharp, but still capable and confident. Under high rpm climb it can begin to bounce, in the way fat tires do when you're in the wrong gear, but felt planted and confident going down the road at 30mph. With no lockout, it's not a great fork for out of the seat and on the bars climbing, but the travel is only 65mm- not a 4" plunger- and if you keep your weight aft and your pedal motion smooth, the bike responds.
This fork does have a purpose, to smooth out unpaved surfaces, and it does that well. It fits that niche of being smoother than a rigid fork (and most telescopic), lighter than any telescopic fork, and makes two-track and some singletrack accessible, safer and faster for the gravel rider.

The Lauf fork on a full suspension bike is an excellent match for
smooth riding with good energy preservation. See discussion below.


It is flexing due to the glassfiber spring construction, see discussion below.

The aim: To evaluate the Lauf trail racer fork on a full suspension mtb.

The Devil’s MTB Advocate: The Lauf fork has been tested before, give
me something new!
The rider: This time it is mounted on a full suspension mtb.

The Devil’s MTB Advocate: It is designed for a hard-tail. The fully bike will
go up and down like a rocking horse.
The rider: That is what we have been testing and more.

The Devil’s MTB Advocate: Come on, there is no lock-out of the Lauf fork.
The rider: On stretches with no obstacles, eg. a flat road, up or down, the
fully is going smoothly with no ’boingy movements’ and the Lauf is
without significant movements.

The Devil’s MTB Advocate: Why not a light rigid carbon fork then?
The rider: On stretches with obstacles the Lauf does it’s job very well in
combination with the rear suspension providing excellent control, traction
and cornering abilities.

The Devil’s MTB Advocate: In previous tests it has been claimed that the
Lauf is flexing, that is, it allows for sideways movements.
The rider: It is flexing due to the glassfiber spring construction, but not so
much that it has an impact on steering abilities on classic cross country
trails or even XCO race circuits.

The Devil’s MTB Advocate: I new there was something!
The rider: Flexing is of course an undesirable movement of forks, but the
Lauf does not feel shaky or uncontrollable. Remember that this is a very
light fork hence the center of gravity is moved closer to the rider and
backwards on the bike in comparison to heavier forks, providing much
better control and smooth riding.

The Devil’s MTB Advocate: Come on, crushing the pedals riding uphill
moving the bike left and right, you want a stiff and locked fork
The rider: The preferred or optimal riding style may be different going
uphill on a fully, but in general the Lauf did allow for aggresive riding.

The Devil’s MTB Advocate: Of course there has to be maintenance.
The rider: Only easy washing so far, although used in almost all weather
and trail conditions, training and races. Just wash and ride.

The Lauf fork on a full suspension bike is an excellent match for smooth
riding with good energy preservation.

The Lauf has been shown to be ideal for cross-country marathon (XCM).
For the fully setup this still holds and the Lauf fully may even be more
favourable for trails characterized by a good flow but with lots of

The very fast rebound of the Lauf combines well with the rear suspension
providing excellent control, traction and cornering abilities.

Pumping for passing of smaller obstacles is much more effectful with this
light fork and then becomes a more natural part of cross-country biking.
