"the world's first gravel fork"

The EC look mentions the rigidity issue with some great pics:

The Invert suffers from neither of those issues as the massive carbon fiber upper structure is both plenty rigid – both fore-aft and through hard corners – and impressively light, the lower legs are relatively stout with 30 mm diameters, and there’s a lot of separation between the upper and lower bushings. I’m not sure how well such an arrangement would work in a longer-travel application, but it seems to do the trick just fine here.
