But you already know what has lower friction compared to sliding friction of bushings. Rolling friction of rollers.Or you could design a super-sealed and pressuried hydraulic chamber in the outer legs where innner stanchions would move. Just like turbocharger ... more »

@Primoz. I checked the FOX drawings, and they as well spec tolerance +-5mm for axle-to-crown distance, the same as RS on Lyrik from 2009. Wheel axle offset tolerances with +-2.5mm :-D. By any means do I consider such variances worth of premium price. ... more »

Why do you consider making the properly toleranced hollow space for sliding bushings a problematic, when manufacturers have no problem with making the properly toleranced hollow space for damper piston? It's not about possibilities, but about their design ... more »

The images show displacement of particular model points (in mm). Not actuall stresses (MPa).

Hi Primoz. I'm attaching picture of very interesting laboratory test that I found when studying Cannondale Ocho fork. That test was performed by Mountain Bike Germany magazine, I don't know when, but according to tested fork models, it must have been
