First Impression: Lauf Carbonara fat bike fork

Let me tell you, few things make quite an impression as seeing one of these in person. The Carbonara fat bike fork is the second major product release from Lauf, after the Trail Racer mountain bike fork, first for 29ers and then for 27.5. Hailing from Iceland, Lauf is a small company dedicated to bringing its radical design to market, and so far these suspension forks are its only product.

The very sight of the Lauf design usually results in the peanut gallery unloading in the comments section of its favorite social media network or making jokes about the brand’s name.* Mountain biking wouldn’t exist without experimentation, so hat’s off to Lauf for trying something new.

My first impression after taking it out of the (exceptionally nice) packaging is that it resembles something Ripley blasted out of the airlock at the end of “Alien.” The fork weighs 1,144 grams with the included, bolt-on axle and tapered steerer tube. It has a 494 mm axle-to-crown measurement and uses a 150 mm hub. It retails for $990 and is available stock in white or matte carbon (pictured). For $100 extra, you can order one custom painted in one of eight Pantone colors.

It works by using a dozen S2 glassfiber plates that flex to allow the axle to move vertically. The Carbonara has 60 mm of travel, and there are bumpstops integrated into the design so you can’t overdo it. I haven’t been able to bottom it out in normal riding. Lauf says the resistance is progressive, meaning it moves more easily through the first third of its travel than the last third. The springs slot into the carbon fiber chassis and are bonded in place, and Lauf says it took thousands of trial-and-error samples until they got the desired flex just right.

The Carbonara is available in two stiffness tunes for the leaf springs: one for riders under 187 pounds and one for riders over 175 pounds. Yes, they overlap. It’s not a weight limit, but more of a guide for how you want the fork to perform. The benefit of such a design? Zero maintenance for one, and no performance degradation from the cold. I’m led to believe it gets cold in Iceland.

I’ve mounted it up to my trusty Salsa Mukluk (which has had approximately 258 different build setups at this point) and we’re headed out to see what it can do.

*If you’re still making puns substituting this brand’s name for “laugh,” please stop. That joke is over. It’s the bike industry equivalent of people making “Seinfeld” references in regards to my last name.
