What The?! Wild Looking Lauf Trail Racer Fork

What The?! Wild Looking Lauf Trail Racer Fork

With 60mm of travel and incredible weight of only 980 grams, the Lauf Trail Racer eliminates as many moving parts as possible. It's made from carbon fiber and uses a set of composite leaf springs which are shockingly flexible and very impact resistant. The fork has a progressive feel to it.

Well polymers (the resin, that holds together composite materials) do have quite a lot of internal damping. But still, you have a ~70 kg weight over it. I doubt they have THAT much damping. I guess he actually did think that it's not that much travel for it not to be a problem. If at all, since he's into prosthetic design, not suspension design (i have a feeling this was more of a design excercise than an engineering design).

groghunter i predict a different problem - using all the travel and not limiting it.

Very cool and innovative, I must say that. But it just gets worse every time I look at it. Nice observation Primoz, 60mm of undamped travel. I guess at 60 you're just taking the edge off the bumps, so controlling that might not be a big deal. The wheel path is another thing. And where are the braking forces going? To one side of a flimsy leaf sprung system? Yuk.

Reportedly, breaking forces are 'neutral'. Also, there are three different weights to the leaf springs. But remember these aren't like steel leaf springs, some crazy fiberglass I read. So don't know how 'springy' they are or if they need damping.

Yeah I can tell those braking forces are neutral as fvck. I mean just look at it. I don't see that pivot moving at all when stabbing the brakes. Not one bit.

I predict the same problem as elastomer setups, too: impossible to get full travel.
