• They are cool.

    Wonder how much the arch adds in terms of stiffness, omitting it for a purely segmented design would seem to offer increased tyre clearance in that instance.

    I got plenty of the 3” tube so I’ll be interested to try and use more it on something I’m building from scratch. Making space for it should be a lot easier then.

  • I can't imagine it adding much to the segmented fork. A reason for adding it could be to close off the bottom of the fork to mud/dirt.

    Using it on the chain stays like you I can see it improving the stiffness like a chainstay bridge - with the stiffness improving linearly with the height of the tube section.
