I was wondering the same. To me it kinda looks like the covered part is welded on the edges. Although, to me, that sounds more expensive than casting one piece

You know aside from the carbon, the shock layout, the yoke, the tube diameter, the paint work, the branding, the build, it's pretty much a knolly.

Last year, for one of my engineering classes I did a simulation in Ansys titled “The influence of the axle diameter on the torsional stiffness in an USD bicycle fork”. It was an exercise more focused on Ansys, not on being scientific, but still the results were interesting. Here’s a link to the presentation . TLDR: 20mm was only 4% stiffer

That's my son @brady_buck_MTB in action. He was so pumped to get to do the photo shoot on this one on his own trail that the SEH groms put so much work into. Give him a follow on YouTube, he'd be stoked.

I reckon axle stiffness inc clamping definitely contributes, but the dominant factors to torsional stiffness in an inverted fork are the tube section properties, bushing spacing, crown/leg interface stiffness and the hub design. As such to say everyone is right 🤷 -20mm axle is stiffer. -Other shit be flexin anyway, so the end user would struggle to notice a difference between axle types.

@sethimus @Evil96 @CascadeComponents I love, like love-love, that someone with an engineering background (and seemingly a degree) and a wealth of manufacturing experience provided factual mathematical evidence, and it has been refuted by "I believe the manufacturer of this shiny new thing I bought", like conformation bias doesnt exist or something.... There's a quote about facts and opinions that I'm trying to remember here...... it'll come to me....

In regard to front axles and stiffness of inverted forks, the angular deflection of a shaft is defined as θ=(T*L)/(J*G). The key variables for axles are J (polar moment of inertia since we're talking about circles) and G (shear modulus of the material). J for a circular cross section is J(r1,r2)=(π*((r1^4)-(r2^4)))/2 where r1 is the OD and r2 is the ID (zero if solid). As for G, the shear modulus of steel is approximately 3x that of aluminum. Now for a comparison between 15 and 20 mm axles... Lets say we have a solid 15 mm axle and want to...

Yeah that is very true, I knew that and you're definitely right, the rear end could very well be the same length considering it's a high pivot there's really no need for a longer back end, chainstay length is also on par with the current supreme. I did some measurements with the front and rear rotor and the perspective is definitely messing with it big time lol.

There's a good amount of perspective/distortion in play. If you take the center of the tire instead of the axle, you'd get a 40mm difference. Not saying the rear center is 420mm, but I'm not sure it's actually a longer backend and not just a stronger rear triangle.
